Alfa 156 JTS 2.0 very weird issue VDC system failure please read!!
Good evening everyone,
I have been driving my 2004 2.0 jts for over three years now. Today as i was driving downtown i parked the car had to do some business for about two hours (it was rainy as hell in Sarajevo), came back sat down to turn on the car and the ignition was working but no engine start. Soon to be displayed an error saying VDC failure error.
My noob initial reaction was to check out relays and fuses and everything seemed fine, after a few desperate tries i had to tow the car to my mechanic.
He tried first to ODB the any faulty codes but it wont connect to the ECU at all, the connection wouldn't happen at all. Then he tried to re-check the relays and fusees and everything seemed fine.
He started investigating the fuel pump and apparently there was no fuel delivered to the engine, after further investigations the fuel pump relay (only black one amongst other reds) was not getting any electricity.
We tried connecting the fuel pump directly via cables to +12v and the pump worked.
Now he is saying its most likely a faulty ECU?!! having been not able to connect the ODB at all and the weird VDC system failure error and also no power to the fuel pump relay he concluded its most likely a faulty ECU and probably will work on replacing that.
Is there a possibility that its an immobilizer/Alarm cutting off power from fuel relay? does the ECU just die like that without any signs of going bad? do you think that the service guy is going in the right direction?
Any ideas, opinions are much appreciated guys.
Thanks for reading my long post.
