I have an Jaguar XJ 6 1995 - the immobiliser and the key fob have gone off tune which immobilises the car. I understand that by disconnecting the battery and then reconnecting you can then reset the immobiliser by going through a press sequence with the key fob. Could you please give me the exact procedure.

hii sure i have the honor to helep you sur I've had a similar problem with my 1995XJ6 - in my case it was a faulty fuel pump. Cost of repacement from David Manners Ltd. approx. ?75 + VAT. Apparently the lead to the pump can also be a problem. To check if fuel is present partly undo fuel rail on the engine and then operate the starter - you should witness fuel spurting out! Have a fire extiguisher handy! If no fuel present suspect the fuel pump relay first - this is located in the boot behind the on the off-side, not far from the rear light control unit. If the relay is OK check the leads to the pump which is mounted in the fuel tank. Access to this will mean removing the spare wheel and the carpeting in the boot. If fuel is present then there is probably something wrong woth the ignition. Although I've eliminated the fuel problem there is still an intermittent problem with the ignition system which defies diagnosis! All the best.


accept regards sur

good luck

Hello, do you know what the locksmith did to get the code on your key? Did anything else flash on the screen when the car would not start. My car is doing the same thing, and my Jaguar dealer is 200 miles away. My screen is showing [Engine Fault, Transmission Fault and DSC Fault]. Any help would be greatly appreciated..

Hello

The locksmith re-coded the key from his computer in his van nothing else flashed on the screen as far as I know but then I wasn't aware of how to view messages I had only had the car one day and was very disappointed. I hope this helps in my opinion it was cheaper to call out a locksmith than to take it on a recovery truck to the dealer. Hope this helps.

Hi

I suspect the cold weather was the fundamental problem, usually emanating from a battery voltage drop, and kicking in the on board computer gremlins.

Jags just don't like it !

Lets hope the weather improves for you there in UK, and your little gremlin does not return.

Good Luck !

John.

hi, try disconecting the battery for a couple of hours and try again but make sure you have your stereo code. if this does not work your key fob may be out cync with your ecu and will require reprograming it is easy on x type , you can do it your self ,you can find the instructions in jag forums or ebay for 1.99
