Hello All, Electronic Control Module ECM on 2003 RS6 has just failed and taken out ABS/ Vacuum pump with it- has this ever happened to anyone? This occurred on a heavy rain day in Northern California- tech. and inspectors are not certain if module had water intrusion or simply failed- very odd? Look of harness and module connections indicate minimal green corrosion (not too bad) apparently considered normal? Not sure if water had been intruding the seal boot all along or this happened all at one time with massive amount of rain and puddles while car was in operation.
Any info. can help. Thx.
