Jaguar X-Type
X400 · 2001-2009Faults written up for this generation: likely causes and the order to check them in.
-
1
Air Conditioning Problems, AC Not Working
On the X-Type, weak cold at idle that returns at motorway speed is usually the control valve inside the compressor, not the compressor — Jaguar's bulletin fix swaps the…
-
2
AUX Input, iPod Module Silent or Freezing
The X-Type radio has no AUX socket; the factory answer is a dealer module that poses as a CD changer.
-
4
Battery Drain, Flat After Standing
On the X-Type the cause is usually simple: a battery ruined by weeks of standing, a lamp left on overnight, or a car left unlocked so it never sleeps.
-
3
Battery Light On While Driving
On the X-Type the engine computer tells the alternator how hard to charge, so a fault in that link or its earths looks exactly like a dead alternator — and a new…
-
1
Diesel Belt Tensioner Noise
The clatter at idle on the diesel X-Type is often blamed on the timing chain; it is almost always the auxiliary belt drive.
-
2
Bluetooth Not Working or NO PHONE
Every X-Type has phone buttons, but they're pre-wiring, not proof of Bluetooth — few cars were ordered with the module.
-
2
CD Changer Not Working
On the X-Type the boot changer fails in two main ways. CDC NO DISC with a full magazine is the changer's own mechanism, usually a slipping drive gear, and a reset only…
-
4
Check Engine Light
On the V6 the light most often means an oxygen sensor or a split PCV hose — both cheap.
-
3
Clutch Problems, Dual Mass Flywheel
On a manual X-Type a clutch that dies suddenly is rarely a worn plate: it is either the hydraulics or the dual-mass flywheel.
-
3
Diesel Limp Mode, Gearbox Fault Message
The Gearbox Fault message is misleading: the gearbox isn't the problem. Three engine-side faults cause it — carboned turbo vanes, leaking injectors, a failed injection…
-
3
Diesel Thermostat Housing
The diesel X-Type has two thermostats. The main one sits in a black plastic housing at the right-hand end of the engine (Jaguar JDE4149, Ford 1633900).
-
3
Diesel Timing Chain
The 2.0 and 2.2 diesel X-Type has a timing chain, not a belt, and no replacement interval. With regular oil changes it goes well past 180,000 miles.
-
5
Door Won't Open, Central Locking Not Working
On the X-Type a door that won't open from outside is usually the handle rod slipped in its clamp, or a dry latch that sticks in the cold.
-
3
DSC System Fault, ABS Light
On the X-Type the usual culprit is a cracked or rusted ABS sensor ring on a rear outer CV joint, and the fix is a CV joint, not a driveshaft or a module.
-
3
Gearbox Fault
Gearbox Fault on the X-Type is a catch-all message: the gearbox module raises it whenever something it relies on looks wrong, so read the codes from every module before…
-
4
Headlights Not Working, Bulb Failure
On the X-Type a dark headlight is usually just a bulb — or the plug on it, melted onto the spade — and access, not the part, is the hard bit.
-
3
Heater Not Working
On the X-Type a heater that blows cold is most often simply low coolant, and heat only when moving is the classic sign.
-
4
Key Fob Not Working
On the X-Type a dead remote is often a good fob that has lost its pairing, or a sticking flap in the key slot that makes the car think the key is still in.
-
2
Overheating
On the X-Type the usual culprit is the radiator fan control module, especially on early cars, followed by the thermostat and coolant leaks.
-
2
Radio Code
The X-Type radio code belongs to the radio's serial number, and the radio will show you that serial: hold EJECT and PTY together. I'd get the code from it first.
-
2
Sat Nav Update and Retrofit
On the X-Type the map and much of the software come from the DVD in the boot drive, so updating the navigation means fitting a newer disc.
-
6
Speakers Not Working or No Sound
Two faults hide behind this. If the tweeters and subwoofer play but the doors are nearly silent, the door speakers have blown — very often all four.
-
3
Touch Screen Not Working, 50 51 Flashing
The screen is almost never the fault. It's a remote control for the navigation computer in the boot and stays black whenever that computer doesn't answer.
-
3
Transfer Case Problems
On the AWD X-Type most whines and rumbles from underneath come from the propshaft centre bearing or a worn transfer box.
-
5
Boot Won't Open, Trunk Release
On the X-Type a lid that won't stay shut is usually the latch closed with the lid up — one press of the boot button on the fob resets it.
-
3
V6 Misfire
On the V6 the rear bank sits under the inlet manifold, so don't guess before the free checks.
-
1
Vibration at Speed
On the X-Type a shake at speed is nearly always the tyres: one out of round, a balance that isn't fine enough, or a worn-in pattern after rotating them.
-
4
Won't Start, No Crank or Crank No Start
The expensive-looking answer is usually the wrong one — I wouldn't buy a control module (quoted around £800) before two minutes with a multimeter at the diagnostic…
