20 Most Recent 2003 Jaguar S-Type Questions & Answers

Have you another key and fob ?

Try lock/unlock cycle with new key + fob. Your key may be corrupted.

Try also just unlocking the car with the key (not the fob) as soon as you unlock the door put the key in the ignition immediately and see if the car starts.

If you have your radio code it may be worth trying a total reset (leave the car unlocked) disconnect the battery and leave for 20 mins. then reconnect, most systems will then reboot and this MAY help?
Failing all the above it looks like dealer time - more ££ss

good luck !

If the coolant isn't low you most likely have a defective coolant level sensor.

You will need to reach up from underneath and either locate the latch and pull it or grip the cable near the latch and pull that to try and release the bonnet catch!

I had the same problem. Restricted performance and running rough at 3000 RPM. I have an OBDII code reader and found that the problem was in the air mass flow sensor, which is just after the air filter. I pulled this out and found it was dirty and had butterfly wings in it. The last shop where I had the oil changed replaced the filter for me but put in the wrong size. Close but no cigar. Bought some *** Flow Sensor cleaner at auto store and fixed the problem. Get an OBDII reader with the ability to erase the codes. Comes in real handy.

you have done something very wrong obviously.
I suggest you get a pro auto electrician round to quote for repairs before you set fire to the car.

Your Dynamic Stability Control and ABS are both critical safety system... Rather than TRYING to LIMP home...
Park BRAKE means focus on the REAR AXLE...!!

It might be Wiser to has a look at each wheel... and under the car to see if a ROAD-HAZARD has taken out speed sensor...
or a similar SAFETY SYSTEMS impairment...

Getting a FREE read from an AUTOZONE (were they're
very likely to try to peddle OXYGEN SENSORS...
(even if your wheel & tire are gone (in MY opinion))...
might be better WITH ALL THAT rather than trying
to LIMP home...

I personally purchase the FACTORY WORKSHOP
repair manuals (XJS: quite expensive)... but WORTH it.

Much cheaper than letting "DEALERS" mess...
things up ...
Be safe... (tow it home... part of that British Charm

Well, there are several "brains" in your car, but most people are referring to the ECU (engine control unit) when they refer to the brain. The ECU interfaces with all of the engine management sensors and adjusts fuel, timing and other performance-related issues real-time as you drive. It uses algorithms written into its programming to make your engine run as efficiently as possible. It also detects problems with engine sensors and equipment and alerts you via the check engine light and the OBD hook-up.

Hope this is an answer to your question,
