General information

  • Carry out road test for at least 10 minutes. o Automatic transmission in ‘P’ or ‘N’.
  • If engine does not start: Crank engine for 6 seconds. Leave ignition switched ON.
  • Data link connector (DLC) – 2-pin: (A) black, (B) brown/white.

Accessing and erasing

  • The engine control module (ECM) fault memory can only be accessed and erased using diagnostic equipment connected to the data link connector (DLC):
o A4/RS4/S4 2000-+, A6/S6/RS6/allroad 1997-> A8/S8 2002 -> fascia, driver’s side [1]
