It has just occurred to me that I have never seen or heard the engine bay fan operate. The car doesn't over heat and has never lost coolant if fact it operates perfectly even after a really hard on track work our. Should I be concerned and if so is there any test I can do for the fan operation?

Mine comes on all the time, though only when I stop. Never when I'm moving.

TF 160 VVC here.

Craig,
If you disconnect the sensor(it sits slightly forward of the expansion tank) the fan should come on all the time.
I'll see if I can find a piccy of the sensor.

Ah there you go!

Mine only comes on on a hot day if I am in traffic, almost not moving.

Mine comes on fairly regularly in the summer. I believe the fan kicks in earlier on an Mpi than it does on a VVC

and i can vouch for it being astonishingly loud!!! put it this way it could be herd over a TT mk3 and Janspeed De-Cat!........ well on idle anyway

The fan normally kicks in when the sensor reads 75° C on an Mpi and 85°C on a VVC
It stops at 60°C (all data depend on the individual ECU timing !).

Make sure fuse 6 is not blown

Thanks for your help everyone, Fan works fine and kicks in at about 80°C - 90°C

Now I have tested it and know it works I have to say I can barely hear it over my D&T exhaust even at idle.

Good to know it works! One thing less to worry about.:rolleyes2:

hmm do the 1.6 TF's have them? well mine has one but it's very small so i assumed it's there i just can't hear it?

Mine is huge.

The engine fan is pretty big, too.
