Hello guys, I recently bought an Audi 80 1.8 S B3 Type 89 as a second car, especially for the winter. The car is year 11/1987 and runs so far still quite well. Now I would like to ask you for your help with the following problem. Since some lamps had failed in the instrument cluster, I had to worry new ones to replace the bad ones. Said, done! First everything went according to schedule. When I had replaced the defective light bulb for the fuel indicator lighting and there The only lighting that still works is for the digital clock. Otherwise all other lamps are dark! (DZM, Tacho, Motortemp.-Display and Tank Display) Can someone tell me what it can be? All other functions, such as DZ, speed, tank content, engine temp. and the control lights for Batt. oil pressure etc. are still in order. I have also changed the corresponding fuse already tried out, le ider without success! Could it possibly be due to the rotary control for the brightness setting? What is surprising is the fact that the newly inserted lamp for the digital clock works, but all the other newly used lamps and the still existing original incandescent lamps do not! I cannot explain this circumstance. Thank you for your efforts! Greetings from sammy_140206
