My daughters 2002 Jetta 1.8T has a fanlike buzz that continues making noise after the engine is off. What is this? is this normal? it is not the engine fan. It sounds like an electric motor. :confused:

That's correct. Often called the auxillary coolant pump. It will run for a few minutes everytime the engine is shut off. Its an small electric pump that from what I understand is only on the automatic tranny version of the 1.8Ts. I have three 1.8 Jetta manuals and none have the aux pump, but the Tiptronic 1.8 has it. Located right above the passenger side radiator fan.
I've never figured out why none of the manual versions have it.
