Motor System Failure......Help
I have a 2001 147 1.6 that has just developed the habit of putting up the Motor System Failure warning, then going into safe mode. First time it happened I made it to an Alfa dealer who took it in and replaced the throttle potentiometer. It was fine for a couple of weeks then the fault appeared again, only this time I switched off then on again, the warning light remained but the car drove normally, not in safe mode. Started it up yesterday morning to return it to the dealer but now no warning light. The guy at the dealer reckons it could be wiring, he rechecked the connections etc.....car fine again today.
Now I'm just driving around waiting for the fault to appear again...has anyone else had a similar problem or any ideas how I could track down the fault without a dealer just changing odd bits and pieces and it costing me a fortune.
Any help or advise much apprieciated.
