      Hey everyone, I own a 2001 S4 with A/T. When I turn the key I do not have a cel light up on my dash and no scanner will connect to the car, the car will crank but will not start. What I have done:
      -checked fuses 10 and 29 (10 was blown, i replaced and still nothing)
      -checked for 12 volts at the back of the ecu adapter pin points, have 12v at 3 and 62)
      -grounds are good
      -relay beside ecu is clicking when key is turning
      -ecu was tested on a friends bench and is 100% fine

      Any help would be greatly appreciated.

      Check the fuse you replaced to see if it blew again then I would say check the engine timing.
