potential ECU problem

[stuart edwards]

hello all, my ongoing problem with my se alhambra diesel is not going away at the moment, its going into limp mode at around 2600 revs, the seat dealers think its time for a new turbo or a faulty ECU, could i please ask if anyone has any experience of an ECU breaking down on their car and the symptoms that it produced. just to add to my confusion yesterday the voltmeter on the dash started to read 11 volts for a while and then went to zero volts, alternator i thought and perhaps the root of all my problems, today the pesky thing is reading a healthy 14.5 volts again, i have cleaned the earth cable where it bolts onto the engine which was very grubby so i dont know if this has helped matters. has anyone had an ECU tested or repaired by seat or an independent?

cheers

I've a Leon FR TDi which has had multiple failures causing it to go into limp mode. The car would drive normally 99% of the time then suddenly fail without warning. Multiple visits to the dealer failed to resolve the problem.

Yesterday, the dealer got someone from Seat to look at the car and he diagnosed a faulty ECU which is being replaced today. I won't be able tell you if this fixes the fault because I'm taking the dealer's offer of a replacement vehicle in a couple of weeks.

have you any idea how the ECU was diagnosed as being the fault, did the seat person have any special teat equipment with him/her

I believe it was hooked up to something for testing but I don't know if it was special equipment he brought with him or if it was standard dealer equipment and the dealer had never bothered to test the ECU before.

I'd recommend speaking to your dealer about getting someone from Seat over to check out your car if it's still under warranty and you feel you aren't getting anywhere with solving your problems.
