Hi Guys,
As the Pistonheads forum search is useless I've posted a new topic.
This weekend my Cayman S has started running the front fan continuously. I guess its a faulty thermostat, has anyone had a similar issue.
Cheers
James

When mine had a dealer service they removed the front bumper and cleared the vents of leaves, rabbits and other detritus. Have you had this done or had a look to see if the vents are blocked?

Just checked, the vents are clear and the fan stops and starts with the air con off, so I'm assuming its not air con related. That works a treat.
Its the fan on the drivers side front. You can really feel the air blowing out the wheel arch.
Also the engine temperature looks fine. Just done a 400 mile trip this weekend, and no issues what so ever, purely the radiator fan cutting in and out.

I have exactly this, only on the nearside (albeit with 997). Seemingly excessive fan activity but everything else seems to be OK.
I virtually never switch off the air-con, but just adjust the temperature to suit. In case it affects anyone else, for a while I've noticed I need to turn up the temperature a bit higher to find a comfortable termperature. Probably just me getting old.

There are 2 fans on the front (as there are 2 coolant rads), one on each side and if one of them has packed up, the other one will work overtime (and eventually fail).
To make matters more complicated there are 2 speeds and the AC should only trigger low speed.
I would check that both side work first as it's a common fault and not particularly cheap to change (£250 to £300 per fan inc labour).

Quick update.
Had the passenger side wheel off and liners. Gave the fan a quick turn which appeared to be a little resistant to start with, like a stone was stuck in there.
Took the car for a spin, and all appears well again.
Looks like I've saved a few quid.

When I had this fault with the Spyder, it received a whole new fan unit under warranty...
