Hi i've got a 2002 passat 2.0 20v 130HP
When I bought it I had an alternator problem and bought a new one,
this is now fitted however over the last few weeks abs waring lights have started coming on when im in traffic.
I called the AA and the only problem they could find is a drop in voltage when at idle speeds and ive got the Climate control on. With just the Climate control and headlights the volate drops from 14.2 to 12.1, and with the heated screen on it goes down to 11.8v.
I've had the alternator replaced under warrenty but the problems still there.
I changed the battery and still no problem
I cant find a bad earth anywhere, and when reved the alternator is capable of 14v no problem, its just at idle.
The garagem who supplied and fitted the alternator are a general electrical specialist and claim that no two alternators could have the same issued and that the regulator is functioning correctly.
they are currently investigating the car but are at a loss to the problem.
Does anyone have any suggestions on how I can get this resolved or what could be causing this problem.
The bigest drain in the climate control but it seems to function perfectly?
Please help if you can!
