I have a 2004 Audi A6 2.7t with about 35k miles. Radiator fan is running
for 10 - 20 minutes even when the engine is not hot, for example, after a 1
or 2 mile drive. Dealer did not show any diagnostic faults and recommended
replacing the temperature sensor, Had the local shop replace the sensor
(dealer wanted over $300) but the situation remains.
So the questions are:
1. Is this normal behavior that I just don't notice before?
2. Any other ideas for what to check or replace?
Thanks for the help.
