:unsure: My fuel and temperature guage do not show any reading. I was wondering if maybe the guages were faulty, but im not certain. If you have any suggestions, please let me know! -Teemu [email protected]

"My fuel and temperature guage do not show any reading."

Is the fuse (S7; 5 A) good?

If so, then looks at the regulator TCA700Y.


Perhaps a bad contact with the printed circuit?
Or TCA700Y is defective?
TCA700Y is a positive voltage regulator 10 V; 1,5 A
To buy a new TCA700Y at Audi or a salesman of electronic components.

Good luck!
