I've had my 2002 TDI for over two years now. Yesterday after an 8 hour trip I turned the engine off and the rad fan stayed on. After about 10 minutes it turn off by it self. I have never before heard this before and the weather is not hot. It is 16C right now.


This morning I turned the ignition on (without the engine running) the fan starts to run (it seems to run slow) and as long as the ignition is on it turns on and off. I heard a click every time it turn on and off. When I turn the engine off it stays on for a while again without turning on and off.

Any ideas?
