Hi all
Had my mk4 r32 since Saturday and absolutely love it. 89000 miles and feels like new compared to my old mk3 vr.
Few bits to do to get it where I want it but am so impressed with these cars.
Only concern is when the cooling fans should cut in.
Any advice would be much appreciated
Cheers
Paul

Hope its nothing major , temp guage dosent creep up past 90 after 10 mins of idling after a brisk run where as my vr fans would be spinning a good en after 2 mins lol
Cheers again

You can't stop it from overheating if you have faulty fans. Just switch the ignition off

Very true lol. But is there something at fault if the temp guage dont move over 90' even after 10 mins of idle after a brisk drive? I can only compare it to my vr6 and I know these cars are worlds apart but wiv the hot weather I would expect fans to cut in or the guage to rise?
Have searched on here for similar probs but they all seem to do with no slow speed fans with air con on etc.
Perhaps im bein paranoid just dont want to damage the engine .
Thanks for any help and your time replying .

Mines never ever gone past 90 after a dogging on a hot day.

My vr6 used to, if the gauge decided it wanted to work

The temperature gauge on the R32, like all modern VWs, is not real time, it's adjusted to display 90 if the actual coolant temp is between around 85 and 105 degrees.

You can either mod by VCDS or display real time on climate control display via "not so secret menu"

Obviously it's as good as impossible to have a real time analogue gauge that would fluctuate so often.

The majority are "damped" for minor fuctuations but modern ones one have a "plateau" across the normal operating range so the gauge sits in the centre position.

On my bikes the temp display was digital and would display real time

Thanks cheempeej thats exactly how id expect it to be, mine stays at 90 too but no fans when it pulls back up on the drive and idles and surely the motor would need cooling after that?
Is there anyway to test the fan module (plug into diagnostics ) ?
Dont know if it makes a diffetence but its got a miltek with stage 1 apr remap
Thanks again

Yeah for sure they should after a run. It won't throw up a fault, break out the multi meter and check the fan control module under the battery tray. But 100% it's the module, you either need a new one or 2nd hand one but the resistor will burn out again likely. Alternatives are buying an external resistor pack from the likes of NIME but at £105 it's not cheap.

Your mods make no difference
