I have a problem in my C5, sometimes, the engine fail to start, the starter motor operates normally but the engine refused to operate and there is ?engine immobilizer fault? message in the central screen.
After a few retries (I wait a few seconds between each retry) the engine start normally and I can drive the car without any problem.
Can sombody help me?
C5 Engine immobilizer fault
Moderator: RichardW
It seems a big problem.
I took the car to Citroen garage. They checked the keys and the antenna and they claimed that the antenna receives the signal but from unknown reason the car does not start.
They suspected that it is the engine computer, they replaced it and the car started but after a few retries the problem rose again with the message: engine immobilizer fault.
they says that they needs more time to discover the reason for the problem, they didn't know how much time it will take.
Does anybody have an idea what to do?
