Cayman cooling

I have a 2009 (facelift) Cayman S. The cooling fans have stopped working after the ignition is switched off and I am not getting help from Porsche Centres. I have been told various stories including that this feature was not fitted to my model, although it worked for most of its life! I've had the car from new and it has 82k miles on it.
 
Are you talking about the front radiator cooling fans or the engine bay cooling fan (on the driver side air intake)? In both cases, the problem could be that the air or water temperatures are not high enough to trip the fan, or there is a faulty temperature sensor or connection. A decent diagnostics tool should pick up sensor or connection faults.
 
Have you turned-off the aircon? I think that if it’s turned-on the coolant fans should run at high speed if the cabin temperature is high enough with the ignition on/engine running?🤔

The dealers are wrong. The fans on my 987.2 CS run when the ignition is turned-off if the coolant temperature is high enough.

I have a 2011 boxster. The engine compartment
fan will run with the ignition off if it needs to. Not sure I have ever noticed the radiator fans doing the same but I guess they could.

The engine compartment fan only does it occasionally. And typically not straight away with ignition , it kicks in when heat soak happens.

This is my second 987.2, the first one behaved the same.

I would suggest that if yours has always run the fans after ignition off then you have (had) an issue that’s now not a problem. Any recent work , service etc. ?
