Could also be the afterrun timer relay, big brown relay located behind
the passengers kick panel. The relay transistor in my went south, and
the relay in the fusebox engaged occationally. I think the sensor is the
one alongside the MFTS, check Scott's site for furter info and test
procedure.

'92 S4 etc..
