Thermostat went out (indicated by the "air coolant overheating" light going on) also, the air cooling fan never turned off even after I turned off the engine - had to remove the timing belt and the front end of the engine, replace the thermostat (so the VW dealership said) and it cost me $1,800!!! Didn't know where else to go, had to get done.
