Two different issues - one is the radiator cooling fan, and one the injector
cooling fan. My 1982 80CD had the former - you could park the car and be
inside the house before it did an imitation of a Jumbo jet landing. This was
a carburretor engine - no injectors to cool. The 1988 ur-quattro has no
afterrun on this fan, but does have an injector cooling fan. It's loud,
perhaps, but it ain't anything _LIKE_ as loud as the 80CD's Jumbo imitation. If
you parked in the street, the 80CD would frighten passers by.
