I've got a 55 reg Fabia Ambiente TDi, about 23 months old, and have the following problem, the engine management light comes on 10 minutes after the engine has been started, the following is the scenario of events:
September 7th, engine management light came on during long journey, over the next couple of days it became apparent that the light would come on after 10 minutes of the engine being started.
September 10th, 20,000 mile service, during this service it was diagnosed that the car had a faulty alternator.
September 22nd, alternator replaced, problem still persists, after 10 minutes, engine management light comes on.
October 2nd, car in all day, diagnosed as a faulty alternator.
October 6th, alternator replaced, problem still persists, after 10 minutes, engine management light comes on.
The work is all being done under warranty at my local main dealer, the car is booked in again on October 16th for more investigations, but I'm fast losing confidence in them.
Anyone got any ideas ??
Thanks
Nick
