Why is it that Jaguar X-Type engine still runs after the engine has been switched off

Hi, fail safe engine mode means that the ECM (Electronic control module) or computer box as some know it, is running in a mode whereby it is bypassing a particular component in the engine that has gone faulty in order to keep the car from cutting out, or has picked up an erratic function in any component, which is more than likely an electrical problem and could be one of the following which have to be checked by computer analysis equipment at the Jaguar agents or any one else that is familiar with the process that is required to trace the fault. Here are the possible causes: 1.Erratic wire connection 2, Engine cooling Fan thermal switch. 3. Control module 4. CKP sensor 5. Computer box not functioning correctly (a rare fault) 6.Engine coolant fan not working, or running erratically. Unfortunately only a computer analyis will depict the location of the fault and if the repair man is very experienced will be able to sort it out quickly with the computer analysis.( Although I strongly suspect it to be the cooling fan thermal switch which is working erratically and will soon fail completely.)
So get your car to the experts as soon as possible especially if it could be the cooling fan thermal switch, which could cost you a major expensive engine repair job if your Jaguar overheats.
Have a good day.

the 1582 code is a flight recorder code meaning that at some point one of the following has happened: the inertia switch has been triggered,throttle body signal has triggered the limp mode,the engine starts but stumble and then shuts off,or engine fail to start,or a engine stall has occured.This is what causes this code.If the issue was resolved,clear the code becuae it can become permanent and although the car will run fine the code will be there without a mil showing.

check coolant level

It is normal for your fan to continue to run for approximately 10mins AFTER shut off your engine. If it run's for longer than that or it drain's your battery,then you have a problem.

but their is an oil cut off switch or so iam informed ,if you lost oil with the engine running then the oil light switch cuts the engine off ,dealer only to reset

Jaguar runs there cylinder numbering different then the north american engines. They go from 1-2-3-4- front to back and bank 1 and bank 2. Bank one is on the passenger side and bank 2 is on the drivers side. This is the s type DOHC V8 (AJ28) engine for your car.

you have a faulty diode plate in altenator................

Have you managed to fix the problem yet..? I'm having the same problem on my 53 plate X-Type 2.0D SE.

Hi m just drain refill  turn the heater to full hot run engine or drive for a couple of miles let it cool and top up   never had any problums with a s type      D

According to Jaguar, the engine has a heater fitted inside the engine which automaticly switches on when you start the engine and switches of at a pre-determaned time, this expells steam from underneath the car, and considered as normal.
Therf are other answers in the Jaguar forum, take a look there. I have the same effect with my X-Type.
