While driving on the city street, the engine overheated and smoke came out. Stopped vehicle on the side road to see what's happening. Drove after engine has cooled off to the next body shop. Diagnostic: engine cooling is leaking, water pump is defect. Timing belt will be affected if not replaced as well.
Water pump bearings were damaged, that caused to rebuilt the whole engine.
We have a 2002 Audi A4 1. 8l with 16,700 miles on it (very very low mileage). At 16,700 miles, the water pump (according to the dealer) went bad . . . For the year of the vehicle, and the very very low usage, I simply find this unacceptable.
