Hallo,
I have posted befor in the general forum, but I suppose this electric forum is better for my problem.
I just want to find out if my problem really, without question, is in the tachoeinheit.
The problem is that when the car is cold, and I turn the ignition key, all lights/indicators that shall come on the first positions of the lock are all right. But when the key is turned to the ignition on position, the lights/indicators that shall light up then (aircondition, various lights/indicators in the tacho, and outside of the tacho too) begin just to flicker. When engine is started and i drive to get the temperature up, the lights settle to normal working.
Can this be related to wiring or relays outside of the tacho, or must the problem be inside the unit?
The local VAG servic said I could find info, schematics etc. on https://erwin.audi.de, but as far I can see, I have to pay for that.
Rolf
