X100 · 1996-2006Faults written up for this generation: likely causes and the order to check them in.

Jaguar XK8 ABS and Traction Control Light
On these cars the ABS and traction lights usually come on together, and the usual culprits are cracked solder joints inside the ABS module (code C1095) or a broken lead…

Jaguar XK8 Antenna Stuck, Antenna Mast Replacement
On the XK8 a stuck aerial is rarely the motor: it's a seized mast or a snapped drive cable left on the spool.

Jaguar XK8 Bluetooth NO PHONE and AUX Input
Most XK8s have no factory Bluetooth, and none has a real AUX socket. If the factory module is there and says NO PHONE, I'd clear the code entry first.

Jaguar XK8 CD Changer E-01, NO DISC or Stuck
On the XK8 a changer showing E-01 rarely needs replacing: usually it's a jammed magazine, a corrupted disc inventory or dry gears.

Jaguar XK8 Convertible Top Repair, Top Not Working
On the XK8 convertible the usual culprit is the pair of high-pressure hoses to the latch above the windscreen: they weep green fluid at the header and the roof stops…

Jaguar XK8 Engine Failsafe Mode
On the XK8 an amber FAILSAFE ENGINE MODE with cruise control dropping out is most often the brake pedal switch, not the engine.
-
4
Jaguar XK8 Gearbox Fault
On the XK8 a GEARBOX FAULT message is as often a bad signal as a broken gearbox: a wheel speed sensor, a weak battery or the gear selector switches can all put it into…
-

Jaguar XK8 Headlights Not Working
On the XK8 headlights that are dead in the manual switch positions but work on AUTO are a light stalk fault: a loose earth wire or broken wiring inside it.
-

Jaguar XK8 Instrument Cluster Problems
On these cars a dead or misbehaving instrument pack is rarely the pack itself. It is usually a weak battery, a plug disturbed during other work, or the ABS module that…
-

Jaguar XK8 Key Fob Not Working, Alarm or Immobiliser
On the XK8 most remote and alarm faults need no new parts: a low battery that leaves the modules confused, a sticking key-in switch, a loose door lock barrel, or a dirty…

Jaguar XK8 Misfire, Coil Packs and Spark Plugs
On the XK8 a misfire is most often a weak coil-on-plug unit or water or oil sitting in the plug wells.
-

Jaguar XK8 Navigation INSERT DISC
The XK8 navigation reads only its own Alpine-format Jaguar map disc — S-Type, X350 XJ and X-Type discs look the same but won't load. I'd read the disc label first.

Jaguar XK8 Nikasil Engine Problems
Every XK8 and XKR built before August 2000 has Nikasil-coated bores, and the engine number, not the VIN, tells you which you have.
-

Jaguar XK8 Oil Leak
On the AJ-V8 the usual source is the cam covers: tired gaskets, bolts that have lost their torque, or the plastic cover itself cracked by a bolt.
-
5
Jaguar XK8 Overheating
On the XK8 overheating is usually a thermostat stuck shut, coolant lost from a leak hidden under the intake, or a tired plastic-impeller water pump.
-
4
Jaguar XK8 Power Steering Leak, Steering Rack
On the XK8 a power steering leak is either the rack itself or a hose at the rack, and the hose is often blamed on the rack.
-

Jaguar XK8 Radio Code After Battery Change
Many North American XK8 radios were never coded, whatever the handbook says — reconnect and carry on. If yours suddenly asks, a hidden set-up option may be set to Euro.
-
5
Jaguar XK8 Radio Not Working, No Sound
Display and tuning work, nothing plays — the amplifier is rarely to blame. It's usually a boot fuse that looks fine and isn't, or a plug or wire off the back of the…

Jaguar XK8 Rear Lights Not Working, Check Rear Lights
On the XK8 rear lights that flicker, glow the wrong colour or die usually come down to a melted earth pin in the tail-light plug.
-

Jaguar XK8 Rear Speakers Only Bass or Muffled
On a premium-sound XK8 convertible from the 2000 model year, bass-only at the rear is how the car was built — the rear speakers run on the subwoofer outputs, and the…
-
3
Jaguar XK8 Restricted Performance, Limp Mode
Restricted Performance doesn't always mean a new engine part — a rebuilt throttle body, re-tensioned connector pins or a properly charged battery can cure it.
-
1
Jaguar XK8 Stuck in Park, Gear Shift Won't Move
On the XK8 a lever locked in Park is almost always the electrical interlock, not the gearbox.
-
4
Jaguar XK8 Timing Chain Tensioner Problems
On the 4.0 V8 built before mid-August 2001, the plastic upper (secondary) chain tensioners crack and drop their shoe, and the chain can jump or snap with no warning…
-
5
Jaguar XK8 Turns Over But Won't Start
When the V8 spins, sometimes too easily, and never catches, the usual culprit is fuel-washed bores after a short cold start — too little compression to fire.
-
6
Jaguar XK8 Window Problems
On the XK8 a door window that drops further each time and won't come back up has usually lost its learned limits: a two-minute relearn fixes it, and a weak battery…

Jaguar XK8 Won't Start, Just Clicks
A single click with bright lights is most likely the starter — quite possibly a remanufactured one fitted about a year earlier, and perhaps still under a lifetime…
