I have an Audi A6 4.2 Avant, '99 model year, and I wondered if anyone could please suggest the source of an electrical problem I'm having...
A couple of days ago I tried to adjust one of the door mirrors (using the knob between the front seats).
It was quickly apparent that this had been a Bad Idea. Firstly, the mirror didn't move. Secondly, the climate control stopped working, the lights in the centre instrument panel went out, and the DIS stopped showing the outside air temperature, and indicated that there was a failure of the oil temperature & level sensor.
I assumed that a fuse had blown, and consulted the driver's handbook to find out which one it might be. As there didn't seem to be any one fuse that would cause a failure of all these things, I inspected all of them - but none had blown. Clever people who know about cars (i.e: not me) suggested it might be caused by the failure of a relay. I took the car to two Audi dealerships, who laughed patronizingly at my suggested relay-failure diagnosis, and indicated that they *might* be prepared (in a week or two, and if I paid them a few hundred pounds) to look at the car to see what the problem might be.
(To digress: is it only here in the UK that customers are treated with such disdain by Audi dealers, or is it a more widespread problem?)
I have a VAG-COM, which now reports only that there's a failure of the "Outside Air Temp Sensor (G17)" and of the "Sensor for Oil Level/Temperature (G266)". Is it possible that these two components, plus the electric mirrors, have failed simultaneously? Or is there, perhaps, an underlying problem?
Any suggestions as to the source of the problem would be very welcome, and would earn my heartfelt gratitude.
Best wishes,
Peter
