X-type gone into what they call limp mode - 2004 Jaguar X-Type

Hi Heidi
A code fault reader needs to be plugged into your vehicle, there are to many possible faults that can cause this to happen to your vehicle and a code reader will give some guidance.
Good luck

try using a scan tool to reset the computer

check the fuel filter, if it plugs up this can cause no fuel flow to engine. Also check the air filter and the plugs, and wires, if not the filter. It can be most anything but hope this helps. or it may of went into limp mode, if so call or take it to a garage.

Try a computer reset disconnect batterie and wait 2 minutes

I would suggest checking all wire connections to the tranny as there may be water in them causing the fault

as have been given limited info re vehicle , it would be a safe option to disconnect the battery for 5 minutes then reconnect and see if that clears the issue, keep me posted if you wish

run the fault codes to find the sensor that put it in limp mode and repair/ replace it . use that scanner to reset the CPU program to get it out of limp mode.

If your mechanic is clearing the code he should also be able to diagnose the code he is clearing. Your transmission is in safe mode or limp home. Take it to a shop that knows what they are doing

Limp mode can be reset as eaily as shutting off the car and restarting it. the computer will then retest the system, if the problem is gone you will not go into limp mode. but if the problem is still evident, you will have to have it repaired before it will work properly.

get diagnostic codes to get a starting point for repairs required
