Jaguar S-Type
X200 · 1999-2008Faults written up for this generation: likely causes and the order to check them in.
-
4
AC Blows Hot Air, Heater Control Valve
On the S-Type the heater control valve (DCCV) seizes, draws too much current and burns the track in the climate module that drives it — so a new valve alone often…

Air Conditioning Problems, AC Not Working
The compressor clutch gets tested first, and it belongs last. On the S-Type the fuse, relay, heater valve and climate module all come before it — a valve the module…
-
6
Battery Drain, Battery Flat Overnight
With a good battery, the S-Type usually goes flat because it never goes to sleep — it thinks the key is in or the ignition is on.
-
3
Battery Light On, Not Charging
On the S-Type I wouldn't start with a new alternator. The engine computer commands its output, so a generic unit can charge and still keep the lamp lit.

5
Bluetooth Not Working, PHONE NOT FITTED
Each message points to a different fault, and the cheapest is usually the answer. PHONE NOT FITTED on a car that used to pair — I'd look at a fibre-optic plug in the…
-
3
CD Changer Stuck, CDC Error
A stuck S-Type changer is usually a mechanical, free fix: one disc tray stops half-way and holds the magazine in.
-
8
Central Locking Problems
On the S-Type, locking that undoes itself a second later is usually the driver's door lock — a worn switch or solenoid inside it tells the system the door never locked…
-
6
DSC Not Available, ABS Fault
On the S-Type, DSC Not Available with ABS Fault usually means one wheel speed sensor has dropped out, most often at the rear.
-
2
Front Suspension Knocking
On the S-Type a knock from the front over small bumps is most often the front anti-roll bar bushes or the drop links, both cheap.
-
3
Gearbox Fault, Transmission Fault
On the S-Type, Gearbox Fault often isn't the gearbox — it names what the car noticed, not what failed.
-
3
Headlights Not Working
On the S-Type, xenon headlights lighting only the road just ahead are usually a failed front level sensor or a broken plastic adjuster inside the lamp.
-
5
Heater Not Working
On the S-Type no heat is usually the heater control valve stuck shut, or simply low coolant from a cracked expansion tank or air in the heater.
-
4
Misfire
On the S-Type a misfire is nearly always an on-plug ignition coil — usually one at a time, often after rain, a car wash or oil seeping into the plug wells.
-
4
Overheating
On the S-Type overheating usually comes down to the electric cooling fan, a split coolant hose or a sticking thermostat.
-
5
Parking Brake Fault
On an S-Type with the electric parking brake, a Parkbrake Fault message is most often low battery voltage, not a broken brake.
-
2
Radio Code
The S-Type radio code belongs to the radio's serial number, and the radio will show you that serial: hold buttons 6 and 1 (or 6 and 2) together.
-
2
Rear Light and Brake Light Problems
On the S-Type, a rear light that goes dim or dead on one side is most often a blown 10 A fuse in the luggage compartment fuse box, even when the fuse was looked at once…
-
3
Restricted Performance
On the petrol S-Type, Restricted Performance or Engine Failsafe Mode usually comes from the drive-by-wire throttle — either the throttle body itself or the sensor in the…
-
3
Rough Idle
On the S-Type a rough or hunting idle is most often air getting into the inlet manifold — on the 3.0 V6, the breather elbow, the hoses under the manifold or the manifold…
-
6
Stereo Upgrade and Radio Replacement
An aftermarket radio fits the S-Type's double-DIN opening with a fascia and an adapter lead.
-
5
Touch Screen Blank, 50 51 on Display
50 and 51 on the small display mean the screen gets no answer from the navigation unit in the boot — the screen itself is almost never at fault.
-
6
Water Leak, Water in Boot
On the S-Type, water in the spare wheel well nearly always comes past the boot lid seal or the welded seams it crosses at the sides of the opening, with the rear lamp…
-
1
Window Problems, Window Regulator
On the S-Type, a window that drops into the door, crunches or stops halfway is almost always the regulator — its cable or a plastic clip lets go, while the motor…
-
2
Wipers Not Working, Wiper Linkage
When S-Type wipers slow down, stop part way across the screen or won't park, the motor is usually fine and the spindles are seized.
-
5
Won't Start, No Crank
Before buying anything, watch the red security lamp by the screen at key position II: on for two seconds then out means the key was accepted and the fault is in the…
