Review: Jaguar X100.I XK8 and XKR (1996-00)

Overview

Released in October 1996, the Jaguar X100 Series I (X100.I) XK range consisted of XK8 and XKR coupes and convertibles. Manufactured in Coventry, England, the rear-wheel drive XK8 and XKR were powered by naturally aspirated and supercharged 4.0-litre V8 petrol engines, respectively, that were mated to five-speed automatic transmissions.

AJ26 and AJ26S engines

Of the engines,

• the naturally aspirated 4.0-litre AJ26 V8 engine had an aluminium block and cylinder head, double overhead camshafts (per cylinder bank), variable cam phasing and four valves per cylinder. From 1998, the engine also featured variable valve timing (known as the AJ27 engine); and,
• the AJ26S engine differed in that it was fitted with an Eaton M112 roots-type supercharger, twin air-to-liquid intercoolers and omitted variable cam timing. In October 1998, the AJ26S was upgraded with an improved engine management system and oil temperature sensor.

While the naturally aspirated engine was mated to a five-speed ZF 5HP24 automatic transmission, the supercharged engine was mated to Mercedes-Benz’s W5A580 automatic unit.

Dimensions

The X100 XK8 coupe was 4760 mm long, 1829 mm wide, 1296 mm tall and had a 2588 mm long wheelbase; convertible models differed in that they were 10 mm taller (1306 mm). For the convertible, the power-operated soft-top roof had one-button operation, automatic latching and a heated rear window; raising or lowering the roof could be completed in 20 seconds.

Suspension

The front suspension used unequal length upper and lower wishbones, while the independent rear suspension featured double wishbones. As an extra-cost option, the XK8 could be specified with Jaguar’s Computer Active Technology Suspension (CATS) which included uprated springs for increased roll stiffness and electronically-controlled, adaptive dampers. The XKR, however, was fitted with CATS as standard.

Safety equipment

Standard safety equipment included dual front airbags, ABS, traction control and mechanically-activated front seatbelt pretensioners.

Features

Standard features for the XK8 included alloy wheels (17-inch wheels for convertibles, 18-inch wheels for coupes), a four speaker sound system with a CD player, climate control air conditioning, leather seats, power adjustable front seats, cruise control, front fog lights, remote central locking, power mirrors and windows, a trip computer, an alarm and immobiliser. The Sport variants were differentiated by their firmer suspension settings, while the Classic variants had burr walnut interior trim and a leather-wrapped steering wheel.

The XKR models were further equipped with 18-inch wheels with sports suspension (for both coupes and convertibles), a six-disc CD player, heated front seats and tilt and telescopic steering wheel adjustment.

October 1999: XK update

In October 1999, the XK range was updated and safety equipment was improved with the introduction of an ‘ABS Plus’ braking system and electronically-activated front seatbelt pretensioners. Standard features were also extended to include a six speaker sound system, while the XKR was fitted with rain-sensing wipers.

AJ26 V8 engine: chain tensioner rattle

For Jaguar XK8 engines produced from 1996 to 2000, the original all-plastic timing chain tensioners or guides were susceptible to stress fractures and could break apart. Symptoms of worn chain tensioners include a rattling noise on start up or unusually rough running – if experienced, the engine should be turned off immediately and not restarted. If the upper chain tensioners fail, the pistons can contact the valves and cause serious engine damage. The lower tensioners can also break, though their breakage does not damage the engine. If the vehicle is fitted with the first generation tensioners, preventive replacement is recommended at 60,000km.

In October 1998, more durable second-generation tensioners (with some metal components) were introduced from engine no. 98102106XX (see technical bulletin 303-30).

In August 2001, all-metal ‘third generation’ tensioners were introduced.Relatedly, Jaguar issued technical bulletin 303-68 in March 2005 for 1997-02 model year Jaguar X100 XK vehicles with VINs in the range 001001 to A24195. In these vehicles, a rattling noise may be heard from the engine on start-up and at idle due to a failed primary or secondary timing chain tensioner. If there was a fault with the primary tensioner, all primary and secondary tensioners had to be replaced. If, however, a secondary tensioner had failed, then both secondary tensioners required replacement. When installing the new secondary tensioner, updated (shorter) bolts were to be fitted.

Nikasil failure

In overseas (i.e. non-Australian) markets and particularly the US, there were cases of the Nikasil cylinder linings degrading due to high sulfur levels in the fuel. Symptoms of worn cylinder liners include difficulty starting, sluggish performance and piston slap. A blow-by compression test will indicate whether the cylinder linings are intact – an engine in good condition should rate between 9 and 19 litres of air per minute; more than 30 litres of air per minute indicates worn liners.

From August 2000, the Nikasil linings were replaced with steel linings (engine serial number 0008181043). The original spark plugs and ignition coils may deteriorate before the manufacturer’s recommended 160,000 km replacement interval, causing rough running and poor starting.

Jaguar X100 XK: camshaft position reluctor misalignment

In August 1997, Jaguar issued technical bulletin 303-08 post-1997 model year Jaguar XK vehicles with VINs in the range 001001 to 011682. In some of these vehicles, the camshaft position sensor reluctor may have been misaligned, resulting in the Diagnostic Trouble Code (DTC) P1396 being stored.

Jaguar X100 XK: camshaft damper adjustment

In February 1997, Jaguar issued technical bulletin 303-05 for post-1997 model year Jaguar XK vehicles with VINs in the range 001001 to 006380. In some of these vehicles, the crankshaft damper may have been loose such that it could shift position on the crankshaft. For the repair procedure, please refer to the technical bulletin. For later vehicles –

• From engine no. ##961028####, Loctite was applied to the crankshaft damper; and,
• From engine no. ##961216####, a split cone locking device was fitted between the crankshaft damper and the crankshaft.

Jaguar X100 XK: part-load engine breather blockage

In October 2004, Jaguar issued amended technical bulletin 600-03 for 1997-01 model year Jaguar XK vehicles with VINs in the range 001001 to A13614. During normal service, the V8 engines in these vehicles could experience partial blockage of the restrictor in the engine part-load breather – this blockage would restrict the correct operation of the engine breather system. As part of Service Action S474, a routine cleaning procedure was to be performed on the restrictor at 16,000 kilometre intervals.

Jaguar X100 XK: buzzing/knocking noise after ignition ‘on’

In June 2004, Jaguar issued technical bulletin 100-24 for 2001-04 model year Jaguar XK vehicles with VINs in the range A11051 to A39957. In these vehicles, a buzzing/knocking noise may be heard when the ignition is switched ‘ON’ or just after engine start-up. According to the technical bulletin, this noise may be due to a radar scanner inside the adaptive speed control module; in some modules, the scanner would hit its end stops, causing a noise. A revised adaptive speed control module, which contained a contactless potentiometer and a new internal actuator, was released to address this problem.

Jaguar X100 XK: Service Action S499 – lower wishbone front bushing

In August 2003, Jaguar issued an amended technical bulletin 204-S499 for 1999-00 model year Jaguar X100 XK vehicles with VINs in the range 034426 to A06104. The lower wishbone bushings in the front arms of these vehicles could split, though this was less likely for vehicles manufactured after February 2000 due to improved parts used from that date. The updated specification replacement parts for the wishbone front arm bushing was MNE 1360CA.

Jaguar X100 XK8: Service Action S468 – rear hub carrier fulcrum bolts

In November 1998, Jaguar issued technical bulletin 204-10 for 1998 model year Jaguar X100 XK8 vehicles with VINs in the range 025588 to 026519. Some of these vehicles may have had outer fulcrum bolts of the incorrect specification in the rear suspension; the fulcrum bolts connected the rear hub carriers to the outer ends of the rear suspension wishbones. As part of Service Action S468, the fulcrum bolts on all vehicles within the above VIN ranges were to be replaced.

Jaguar X100 XKR: pinion oil seal leak

In May 2004, Jaguar issued technical bulletin 100-23 for 2003-04 model year Jaguar XKR vehicles with VINs in the range A30645 to A41576. In these vehicles, there may be a noise from the supercharger drive belt after a cold start. A revised drive belt (part no. C2C 26235) was released to address this concern.

Jaguar X100 XK: steering rack knock or rattle

In April 2002, Jaguar issued an amended technical bulletin 211-06 for post 1997 model year Jaguar XK8 vehicles with VINs after 001001. In these vehicles, the driver may experience a rattling or knocking noise from the steering rack. For the Jaguar XK, a modified lower steering column entered production from VIN A11051. For affected vehicles, the modified lower steering column could be fitted as well as a new steering rack return line.

Jaguar X100 XK8: steering rack leak

In August 1997, Jaguar issued technical bulletin 211-01 for post 1997 model year Jaguar XK8 vehicles with VINs after 001001. In these vehicles, the steering rack may leak at one of the transfer pipe union nuts as a result of damage to the O-ring seal beneath the union nut caused during installation. To fix, the O-rings were to be replaced.

Jaguar X100 XK: click or clunk noise from Drive to Reverse

In February 1998, Jaguar issued technical bulletin 205-05 for 1997 to 1998 model year Jaguar XK8 vehicles with VINs in the range 001001 to 022125. In these vehicles, the driver may hear a ‘click’ or ‘clunk’ noise, particularly when changing from Drive to Reverse or vice versa. To address this condition, a revised torque specification for the nuts and bolts which secured the rear universal joint flange of the drive shaft to the differential pinion flange was introduced in production from VIN 022126 (67 Nm). Furthermore, ‘Loctite’ thread-locking compound was applied to the bolt threads during vehicle assembly. Both these measures could be applied to affected vehicles.

Jaguar X100 XK: unable to move from park & ‘Failsafe’

In April 2002, Jaguar issued an amended technical bulletin 206-07 for 1997-00 Jaguar X100 XK vehicles with VINs in the range 001001 to A03097. In these vehicles, drivers may experience the following:

• Being unable to remove the gear lever from the ‘Park’ position when depressing the brake pedal;
• The brake lights may illuminate without depressing the brake pedal; and,
• ‘FAILSAFE’ may be displayed in the message centre and Diagnostic Trouble Code (DTC) P1571 may be stored in the ECM.

To address these concerns, an improved brake pedal switch assembly was introduced on XK vehicles from VIN A03098. The improved brake pedal switch assemblies were interchangeable with those previously fitted.

Jaguar X100 XK: parking brake release

In April 1998, Jaguar issued an amended technical bulletin 206-01 for post-1997 model year Jaguar XK8 vehicles with VINs in the range 001001 to 009013. In these vehicles,

• The parking brake (handbrake) warning lamp may remain on; and/or,
• A rattle noise may be heard from the rear of the vehicle on uneven road surfaces.

Readjustment of the parking brake mechanism could provide a more positive return to the hand brake lever, ensuring that the warning lamp would not remain on. Furthermore, removing the slack from the cable would eliminate rattle which may be caused by the hand brake equalizer. A secondary return spring and bracket were introduced at VIN 009014; for instructions on installing these components, please refer to the technical bulletin.

Jaguar X100 XKR: Brembo brake vibration

In February 2005, Jaguar issued technical bulletin 206-11 for post 2001 model year Jaguar XKR vehicles with Brembo brakes and VINs after A22191. In these vehicles, there may be a vibration when the brakes are applied, even after the front brake discs have been replaced. To fix this condition on a repeat repair, new front brake discs were to be installed on the hub flange in a position which minimised the lateral run-out of the brake disc. For further information, please refer to the service bulletin.

Jaguar X100 XK: ticking noise from footwell

In November 2004, Jaguar issued an amended technical bulletin 303-62 for 2003-05 model year Jaguar XK vehicles with VINs in the range A30645 to A40920. In these vehicles, there may be a ticking noise from the left footwell when the vehicle is driven at low speeds. A modified Evaporative Emissions (EVAP) Canister Purge Valve was introduced to address this concern. After installing this valve with a new insulation pad, the engine control module (ECM) needed to be reprogrammed.

Jaguar X100 XK: coolant leaking from heater hoses

In February 2002, Jaguar issued an amended technical bulletin 303-48 for 1997-99 model year Jaguar XK vehicles with VINs in the range 010343 to 042635. In these vehicles, coolant may leak from the heater hoses. To fix, both heater hoses were to be replaced and the coolant system flushed.

Jaguar X100 XK: TPS, wiring harness connector and DTC P0121

In November 2002, Jaguar issued technical bulletin 303-58 for 1999-01 model year Jaguar XJ vehicles with AJ27 engines and VINs in the range 853936 to F40117. In these vehicles, Diagnostic Trouble Code (DTC) P0121 (Throttle Position Signal) may be stored in the ECM due to a mismatch of electrical connector terminal materials between the Throttle Position Sensor (TPS) and the wiring harness electrical connector (gold terminals on the TPS and tin terminals on the wiring harness). To fix, new gold terminals were to be installed into the TPS wiring harness electrical connector.

Jaguar X100 XK: difficulty starting and engine hesitation

In April 2002, Jaguar issued technical bulletin 303-52 for 1999-00 model year Jaguar X100 XK vehicles with naturally aspirated AJ27 engines and VINs in the range 031303 to A11050. In these vehicles, two conditions may arise:

• Difficulty starting or a failure to start from cold when the vehicle travelled only a short distance the previous day (1999-00 model year vehicles); and,
• Slight engine hesitation when the air conditioning or slow speed-cooling fan operated (2000 model year only).

For affected vehicles, the engine control module (ECM) was to be reprogrammed using the JTP 759/12 or later version of the Worldwide Diagnostic System (WDS) disc.

Jaguar X100 XKR: loss of performance due to loose intake ducts

In August 2003, Jaguar issued amended technical bulletin 303-57 for 2000-03 model year Jaguar X100 XKR vehicles with VINs in the range A0001 to A33944. In these vehicles, a loss of performance may be experienced due to the intake ducts not being fitted securely. Revised ducts and clamp plates were introduced to fix this problem.

Jaguar X100 XKR: ‘restricted performance’ and limp home mode

In March 2002, Jaguar issued technical bulletin 303-49 for 2000-02 model year Jaguar XKR vehicles with VINs in the range A00083 to A22973. In these vehicles, the ‘Restricted Performance’ message may be displayed on the message centre to indicate that the vehicle is running in ‘Limp Home’ mode. A revised engine management system calibration was issued to prevent this condition.

Jaguar X100 XK: overheating and coolant pump

In April 2003, Jaguar issued amended technical bulletin 303-60 for post-1997 model year Jaguar X100 XK vehicles with VINs after 001001. This technical bulletin was issued due to the unnecessary replacement of coolant pumps in response to overheating, incorrect diagnosis of leakage or incorrect identification of impeller material.

For Jaguar XK vehicles with VINs in the range 001036 to 028000, the coolant pump was to be replaced if it had the following part number: 96JV-8501-CA, 96JV-8501-CB, 96JV-8501-CC or 96JC-8501-CD. To check the coolant pump part number, the coolant pump pulley had to be removed.

For Jaguar XK vehicles with VINs after 82001, it was not necessary to remove the coolant pump pulley for inspection unless there was a genuine coolant pump concern.

Jaguar X100 XK: chirping accessory drive belt

In January 2003, Jaguar issued technical bulletin 303-59 for 2001-02 model year Jaguar X100 XK vehicles with VINs in the range A11051 to A30644. In these vehicles, a chirping noise may be heard from the Front End Accessory Drive (FEAD) due to misalignment of the drive belt. For affected vehicles, a revised FEAD belt tensioner and a new FEAD belt were to be fitted; the Air Conditioning (A/C) compressor locating dowel was also be checked to see that it was installed correctly (i.e. it should be protruding by at least 3.2 mm). If not, a new A/C compressor/PAS pump bracket was also to be fitted.

Jaguar X100 XK: DTC P0442, P0455 and P0446

In July 2001, Jaguar issued technical bulletin 303-46 for 2000-01 model year Jaguar X100 XK vehicles with VINs in the range A00083 to A13691. In these vehicles, the Malfunction Indicator Lamp (MIL) may illuminate with Diagnostic Trouble Codes (DTCs) P0442, P0455 and P0466 stored in the ECM. According to the technical bulletin, this condition could be caused by internal corrosion in the vapor pipe that vented the carbon canister to the atmosphere – this caused rust particles to enter the Canister Close Valve (CCV), causing the valve to stick open. To fix, the vapor pipe and CCV were to be replaced.

Jaguar X100 XK: hesitation and rough idle

In December 2004, Jaguar issued technical bulletin 303-67 for post-2003 model year Jaguar X100 XK vehicles with VINs after A30645. In these vehicles, the engine may hesitate during acceleration or have a rough idle; the Malfunction Indicator Lamp (MIL) may also illuminate. According to the service bulletin, these symptoms may be caused by contaminated fuel injectors.

Jaguar X100 XKR: wiring harness change & Service Action S844

In March 2004, Jaguar issued Service Action 303-S844 for 2003 model year Jaguar X100 XKR vehicles with VINs in the range A29176 to A36998. In these vehicles, a wiring harness change made at the introduction of the 2003 model year on XKR vehicles prevented the P111 OBD System Readiness flag from being set – this would prevent the comprehensive component monitor (CCM) from successfully completing. As a result, vehicles may be rejected by Inspection and Maintenance (IM) stations during their periodic checks. To fix, the Engine Control Module (ECM) was to be reprogrammed with updated software and a revised purge valve installed.

Jaguar X100 XKR: exhaust gas recirculation (EGR) transfer pipe

In July 2004, Jaguar issued an amended technical bulletin 309-S501 for 2000-02 model year Jaguar XKR vehicles with VINs in the range A00116 to A27550. In these vehicles, the Exhaust Gas Recirculation (EGR) transfer pipe fitted to vehicles within the above VIN range may crack due to a combination of normal engine resonance and the form of the pipe. If cracked, the ‘check engine’ Malfunction Indicator Lamp (MIL) may illuminate and the engine may make more noise than usual. As part of Service Action S501, the EGR transfer pipe was to be replaced with a redesigned EGR transfer pipe for all vehicles within the above VIN range.

Jaguar X100 XK: corrosion of canister close valve & Service Action S841

In January 2004, Jaguar issued Service Action 303-S841 for:

• 1999-01 model year Jaguar XK vehicles with VINs in the range 031303 to A13961; and,
• 2000-01 model year Jaguar XKR vehicles with VINs in the range A00001to A13961.

In some of these vehicles, the canister close valve (CCV) to filter vapor pipe may internally corrode, causing rust particles to flow into the CCV. For these vehicles, the filter vapor pipe was to be replaced with a later specification vapor pipe.

Jaguar X100 XK: oil cooler feed pipe & Service Action S846

In November 2004, Jaguar issued amended technical bulletin 303-S846 for 2004-05 model year Jaguar X100 XK vehicles with VINs in the range A39699 to A41740. In these vehicles, a failure could occur at the outer crimp face of the oil cooler feed pipe/hose that led from the engine to the intermediate connector. This same problem could occur on the oil cooler return pipe/hose leading from the intermediate joint back to the engine. These conditions could result in engine oil loss and reduced performance.

As part of Service Action S846, the feed hose/pipe from the engine to the intermediate connector and the oil cooler return pipe/hose from the intermediate connector back to the engine were to be checked for a date code of ’43 03′. If the date code was illegible, absent or ’43 03′, both pipes/hoses were to be replaced.

Jaguar X100 XK: Service Action S514 – engine cuts out

In November 2004, Jaguar issued amended technical bulletin 303-S514 for 1997-98 model year Jaguar XK8 vehicles. In these vehicles, operation of the throttle could cause the engine to cut out, although the engine would continue to be driven by the road wheels through the transmission and drive the ancillaries (so there should be no loss of power steering, brakes, air conditioning, etc). The engine should restart without difficulty once the vehicle had come to rest.

As part of Service Action S514, the following measures were to be performed:

• 1997-98 model year Jaguar XK vehicles with VINs in the range 001036 to 020734: reprogram ECM; and,
• 1998 model year Jaguar XK vehicles with VINs in the range 020735 to 031302: replace throttle body.

Jaguar X100 XK: Service Action S498 – ‘Engine Fail Safe’

In July 2003, 2004, Jaguar issued amended technical bulletin 303-S498 for 1999 model year Jaguar XK8 vehicles with VINs in the range 036938 to 042591. In these vehicles, engine performance may be impaired by a manufacturing issue with one of the throttle body components – this would cause the Malfunction Indicator Lamp (MIL) to illuminate and the message ‘Engine Fail Safe’ to be displayed on the message centre. If the date code on the throttle body was in the range 10T5 to 11T25 (inclusive), the throttle body was to be replaced.

Jaguar X100 XK: fuel smell or DTC P0455

In February 2005, Jaguar issued technical bulletin 303-63 for 1999-02 model year Jaguar XK vehicles with VINs in the range 031303 to A30644. In these vehicles, a fuel smell may emanate from the evaporative system or Diagnostic Trouble Code (DTC) P0455 may be stored in the Engine Control Module (ECM). According to the service bulletin, this condition may be caused by the purge valve corroding and sticking closed. To fix, a modified Evaporative Emissions (EVAP) Canister Purge valve, filter and hose were to be replaced.

Jaguar X100 XK: transmission thumps when cold

In August 2003, Jaguar issued technical bulletin 307-14 for 2000-02 model year Jaguar X100 XK vehicles with naturally aspirated engines and VINs in the range A00083 to A30644. In these vehicles, the driver may experience ‘transmission shift quality issues’, most noticeable when the engine air intake temperature is between 20-30 degrees Celsius and when coolant temperature is below 40 degrees Celsius. In these conditions, engine speed would increase to 1300 rpm for an initial 30 seconds and then reduce to 1000 rpm. During the initial period when the engine speed is at 1300 rpm, the driver may experience the following:

• With no throttle application, the transmission hesitates and then thumps into gear when shifting from neutral to drive; and,
• With no throttle application, the transmission hesitates and then thumps into gear when shifting from neutral to reverse.

For affected vehicles, a new Transmission Control Module (TCM) was to be installed.

Jaguar X100 XK: transmission recall (US only)

In July 1999, Jaguar issued technical bulletin 307-11 for 1999 model year Jaguar XK8 vehicles with VINs in the range 031401 to 038608. For a limited number of these vehicles, the ZF 5HP24 automatic transmission may have a component which had the potential for failure due to an incorrect manufacturing process. In the event of the component concerned failing in one possible manner, the complete powertrain of the vehicle could lock up (though this was only likely to occur at very low vehicle speed as the transmission downshifted into 1st). For affected vehicles, the transmission was to be replaced.

Jaguar X100 XK8: squawk noises on gearshifts

In December 2007, Jaguar issued technical bulletin JTB00070 version 1 for 2003-05 model year Jaguar X100 XK8 vehicles with VINs in the range A30645 to A48684. In these vehicles, the driver may hear a squawk noise from the automatic transmission when changing into third gear; the noise may also occur on kick-down from fourth to third and sixth to third gears. A squawk or chirp noise can also be heard when changing from third to fourth gear at 50 per cent throttle. According to the technical bulletin, the likely cause of these noises is that the ‘E’ clutch sticks and releases when engaging and disengaging gear. To fix, one litre of an additive (C2C 37157) should be injected into the transmission using a syringe.

Jaguar X100 XK: DTC P0741 and replace torque converter

In August 2003, Jaguar issued technical bulletin 307-15 for:

• 2003 model year Jaguar XK8 vehicles with VINs in the range A30645 to A35317; and,
• 2003 model year Jaguar XKR vehicles with VINs in the range A30645 to A35726.

In these vehicles, the Malfunction Indicator Lamp (MIL) may illuminate and Diagnostic Trouble Code (DTC) P0741 (torque converter clutch stuck open) may be logged in the transmission control module (TCM) and engine control module (ECM). According to the service bulletin, a fault was found with the clutch lining of the torque converter and a modified torque converter was introduced to fix the problem.

Jaguar X100 XK: poor heater performance

In September 2001, Jaguar issued an amended technical bulletin 303-11 1997-99 model year Jaguar XK vehicles with VINs in the range 001001 to 042635. In some of these vehicles, the anti-freeze solution in the cooling system may deteriorate and reduce circulation through the heater core, resulting in poor heater performance. For vehicles with poor heating, the coolant was to be replaced with XLC Extended Life Coolant (introduced after VIN 042635 for XK vehicles). For further information, please refer to the service bulletin.

Jaguar X100 XK: instrument pack assembly and CAN failure

In December 2001, Jaguar issued amended technical bulletin 413-S484 for 2000 model year Jaguar XK vehicles with VINs in the range A00116 to A05322. Some of these vehicles may display multiple electrical circuit malfunctions such as:

• Multiple warning lights;
• No messages displayed on the message centre;
• All or some gauges go to zero;
• Gear selector will not come out of the park position; and,
• No A/C operation.

According to the technical bulletin, these malfunctions may be due to a Controller Area Network (CAN) failure in the instrument pack caused by a short to ground – this was due to a combination of pressure from the instrument pack back plate and possible migration of solder on certain printed circuit board (PCB) contacts.

Coolant/water pump failure

In April 2003, Jaguar issued Technical Service Bulletin (TSB) 303-60 due to water pumps which had nylon impellers that could wear and break up, potentially causing the engine to overheat. As such, coolant pumps with the following part numbers were to be replaced:

• 96JV-8501-CA;
• 96JV-8501-CB;
• 96JV-8501-CC; and,
• 96JV-8501-CD.

For the Jaguar X100 XK, this corresponded to serial numbers (i.e. last six digits of the VINs) 001036 to 028000. It is understood that these serial numbers correspond to Jaguar XK and XJ vehicles manufactured prior to 1998.

For vehicles after these serial numbers, the water pump had phenyl sulphide impellers which were not susceptible to wear.

Jaguar X100 XK: revised fuel filler cap

In June 2005, Jaguar issued amended technical bulletin 310-S509 for 2001-03 model year Jaguar XK vehicles with VINs in the range A11051 to A35295. In these vehicles, it may be difficult to properly seat the fuel filler cap due to a large lead angle on the fuel filler cap. Incorrectly installed fuel filler caps could leak to a vapor leak and result in the ‘check engine’ Malfunction Indicator Lamp (MIL) illuminating. For vehicles in the above VIN range, a revised fuel filler cap was to be installed.

Jaguar X100 XK: slow convertible roof operation

In April 2003, Jaguar issued amended technical bulletin 501-33 for 1997-99 model year Jaguar XK vehicles with VINs in the range 001001 to 037188. In some of these vehicles, the convertible top may operate slowly or experience slow/erratic of the latch – this may be caused by a tendency of the Univis hydraulic fluid in the system to slowly evaporate and, in certain conditions, to gel within the hydraulic system pipes and hoses. From VIN 037189, vehicles in production were filled with an improved fluid, Pentosin CHF 11S.

If the hydraulic fluid was low, it should be topped up using the Pentosin fluid and the top cycled to see if performance returns to normal. If this failed to resolve the problem, however, the service bulletin described a more extensive repair procedure.

Thermostat failure

For V8 engines from the late 1990s, the thermostat should be replaced every two years as a failed thermostat can cause secondary problems such as the engine warning light, low coolant indicator and other symptoms.

XK8: ZF 5HP24 transmission

For the Jaguar XK8 (but not XKR), the five-speed ZF 5HP24 automatic transmission was described as a ‘sealed for life’ unit, though transmission fluid changes are recommended every few years. For this transmission, a steel retraining clip can wear through the steel surround and fall out, causing the gears to slip or require higher engine speeds before ‘Drive’ engages.

XKR: Mercedes W5A580 transmission

For the Jaguar XKR, the output shaft and planetary gear assemblies for the Mercedes W5A580 transmission were susceptible to failure.

Suspension

• Knocking noises from the rear suspension may be due to worn bushes in the A-frame which forms part of the rear suspension.
• Worn wheel bearings can cause accelerated tyre wear.
• For XK vehicles fitted with CATS (Computer Active Technology Suspension), the wires connecting the suspension to the main wiring can experience wear – this may cause a warning light on the dashboard to illuminate. To fix, a section of wiring loom will need to be replaced.

Supercharger noise

For the Jaguar XKR, rumbling noises from the supercharger may be due to worn bearings which require replacement.

Power adjustable seats

The power adjustable seat fuses may fail due to chafing of the wiring harness near the seatback; a harness repair kit was released for this problem.

Recalls: Jaguar X150 XK and XKR

Overview

Manufacturers, or importers, issue recalls for defects or faults which have the potential to cause injury. Generally, manufacturers will inform the original buyers if their vehicle is subject to a recall and of the steps required to remedy the defect or fault. Please note that the recalls below (if any) are for Australian-delivered vehicles only. Furthermore, the number of recalls should not be taken as an indication of a model’s reliability or its safety more generally.

Recalls: Jaguar X150 XK and XKR

• In May 2008, a recall was issued for Jaguar XK models produced from 2005-09 due to restraint control modules being incorrectly configured for left-hand drive vehicles and affecting the deployment of the side airbags (PRA 2008/10033).
• In August 2010, a recall was issued for Jaguar XK models with naturally aspirated 5.0-litre V8 engines in the VIN range B28268 to B39482. The in-tank electric fuel pump for these vehicles may not activate correctly following the start-up cycle, potentially causing the engine to cut out. Power assisted steering could also be lost if the vehicle speed dropped below the torque converter’s speed threshold (PRA 2010/11929).
• In March 2011, a recall was issued for 2010 Jaguar X150 XK and XKR model year vehicles with petrol engines and in the VIN range B34722 to B38302. In these vehicles, power steering pipes were manufactured with zinc-nickel plating that did not meet corrosion protection requirements. As a result, the pipes could corrode, leading to pin-holing of the pipe; this could allow pressurised power steering fluid to leak into the engine bay, causing a loss of power assistance steering system and possible ignition of the fluid (PRA 2011/12445).
• In April 2014, a recall was issued for 2013 model year X150 XKR-S vehicles that had serial numbers (i.e. the last six digits of the VIN) in the range B51453 to B54244. After prolonged racetrack use, it was possible that the toe link in these vehicles could fracture and separate from the rear subframe. If this occurred, the vehicle would not be stable and may pose a hazard to the driver and other road users (PRA 2014/14046).

Jaguar X150 XK: engine won’t crank and ‘DSC not available’

In July 2006, Jaguar issued technical bulletin XK206-002 for 2007 model year Jaguar XK vehicles with VINs in the range B00001 to B05215. In these vehicles, the engine may not crank and ABS Diagnostic Trouble Codes (DTCs) C0082-54 or C0044-28 may be stored. When this occurs, the ABS module is unable to provide the required brake pressure inputs to the Central Junction Box (CJB) such that the engine crank sequence cannot be initiated. In this situation, the engine would not crank and the message ‘DSC not available’ would appear on the message centre. To fix, the ABS pressure sensor was to be re-calibrated.

Jaguar X150 XK: front brake caliper creak

In June 2006, Jaguar issued technical bulletin XK206-001 for post-2007 model year Jaguar XK vehicles with VINs after B00001. In these vehicles, the driver may hear a creaking noise from the front brakes under light brake applications, at slow speeds and while steering. The noise may also be heated under light or medium braking while coming to rest with the steering wheel in the straight-ahead position. According to the technical bulletin, these symptoms could be due to contact between the calliper carrier and brake pad anchor points. To fix, the front calliper carrier and brake pad anchor surfaces should be cleaned and greased.

2007-09 model year Jaguar X150 XK 4.2 V8: engine won’t start or stalls

In December 2012, Jaguar issued Technical Bulletin JTB00268NAS2 for 2007-09 model year Jaguar X150 XK vehicles that had 4.2-litre naturally aspirated V8 engines. According to the technical bulletin, the driver may experience difficulty in getting the engine to start (a ‘rough start’) or the engine may stall following a hot soak of 15-20 minutes (i.e. the engine had previously been running but had been off for 15-20 minutes). According to the technical bulletin, this could be caused by the fueling calibration not being ‘robust’ for 10 per cent ethanol fuel. To fix, the Engine Control Module (ECM) software was to be updated. The affected Jaguar X150 XK vehicles had serial numbers in the range B00001 to B32752.

2010-12 model year Jaguar X150 XK: faulty fuel gauge

In March 2014, Jaguar issued Technical Bulletin JTB00301NAS1 for 2010-12 model year Jaguar X150 XK vehicles that had 5.0-litre V8 petrol engines (naturally aspirated and supercharged). In these vehicles, the fuel gauge may:

• Not work;
• Not show more than half full;
• Fluctuate; and/or,
• Switch on/off intermittently.

According to the technical bulletin, these symptoms could be caused by:

• Backed-out pins
  • internal to the fuel tank (sender wiring);
  • in the fuel pump module; and,
  • in the fuel tank flange assembly; or,
• Fretting corrosion across the fuel sender harness pins inside the fuel tank (black connectors).

To fix, the fuel sender harness was to be modified; this process is described in Technical Bulletin JTB00301NAS1. The affected Jaguar X150 XK vehicles had serial numbers in the range B32753 to B47682.

2010-14 model year Jaguar X150 XK 5.0L Supercharged V8: rattling/knocking noise from supercharger

In May 2014, Jaguar Land Rover issued Technical Bulletin JTB00349v2 for 2010-14 model year Jaguar X150 XK vehicles that had 5.0-litre supercharged V8 engines. For these vehicles, the owner may hear a loud clattering, rattling or knocking type noise from the engine bay, specifically the supercharger. This noise could be due to wear on the torsional isolator and/or the torsional isolator spring support shaft, causing excessive backlash in the supercharger drive.

To fix,

• The supercharger belt drive was to be removed and the supercharger pulley rotated by hand;
• The supercharger spring isolator kit was to be fitted if there was a clunk or knocking noise from the supercharger, or if there was significant free play when turning the pulley before the rotors started to turn;
• If any of the following symptoms were present, the supercharger was to be replaced:
  • The pulley did not rotate freely (i.e. it would stick, be difficult to move or roughness could be felt in the bearing during rotation;
  • The blades/rotors were damaged; or,
  • During normal engine operation, the supercharger made an excessive whine noise.

The affected Jaguar XK vehicles had serial numbers after B32753.

Supercharged V8: rattling noise

A rattling noise from the Jaguar XKR’s variable valve timing system may be due to its hydraulics. If so, the variable valve timing system requires replacement.

ZF transmission

The six-speed ZF automatic transmission is described as a ‘sealed for life’ unit, though specialists recommend changing the oil every 100,000 kms; the filter in the gearbox should also be replaced. Leaks from the automatic transmission may be coming from the connector sleeve.

Suspension

• CATS failure: For XK vehicles with Jaguar’s CATS (Computer Active Technology Suspension), the electronic components within the dampers tend to fail around 100,000 kms.
• Around 100,000 kms, the lower wishbones and all suspension bushes may require replacement to maintain the XK’s ride and handling qualities. Worn lower wishbones and bushes may cause uneven tyre wear, vague steering or shuddering when braking.
• A knocking noise from the front end may be due to a dislocated lower control arm bushing for the stabiliser bar.

Hand-brake failure

There have been reports of the electric park brake failing at around five years of age.

Jaguar X150 XK: seats

The power adjustable front seats may move roughly due to a lack of grease on the seat rails. If the seats do not move at all, the motor may have failed or the module may not be responding to the wake-up signal from the network.

The seatbelt warning light may illuminate and the warning chime may activate intermittently even though there is nobody in the passenger seat due to a faulty seat occupant sensor.

Released in June 2006, the Jaguar X150 Series I (X150.I) XK range consisted of the XK and XKR models, both of which were available as two-door coupes or convertibles. Manufactured in Birmingham, England, the rear-wheel drive XK and XKR were powered by naturally aspirated and supercharged 4.2-litre V8 petrol engines… Read full Jaguar X150 XK review

Released in November 2000, the Jaguar X100 Series II (X100.II) XK8 and XKR introduced improved safety equipment, additional features and mechanical changes. The range was also revised as the ‘Sport’ variants were discontinued and the ‘Classic’ variants were no longer identified as such. The Jaguar X100.II XK8 and XKR could be identified by their new ‘jewel-like’ tail-lights with chrome surrounds, new front and rear bumper covers, a chrome boot lid plinth, the omission of front fog light recesses, new alloy wheel designs for the XK8 and, for the XKR, larger tail pipe finishers.

Released in October 2002, the Jaguar X100 Series III (X100.III) XK8 and XKR introduced new engines and transmissions. The 4.2-litre AJ33 V8 engines were stroked versions of their predecessors, but also featured stiffer blocks, oil-cooled pistons, new exhaust manifolds and camshafts, small-pitch silent camchains, bigger cylinder-head porting, an upgraded fuel system and vane-type variable cam phading. Furthermore, the five-speed automatic transmissions were also replaced by ZF’s six-speed 6HP26 automatic. The Jaguar X100.III XK could be identified by its new badging, alloy wheel designs and paint finishes (Jaguar Racing Green, Ebony, Midnight and Adriatic Blue); XKR variants could also be identified by their standard xenon headlights. Inside, there were new interior trim combinations (Warm Charcoal contrasted with Heritage Tan or Cranberry) and a revised J-gate gear shift.
