Sorry to wade straight in with a question having just joined the forum.
I have a 2010 Mk6 GT TDI which is a fantastic car.
Since purchase, bought from new in 2010, it continues to run the cooling fan for around 10 to 15 minutes once parked up.
We have repeatedly spoken to the local dealer about this and they say it is the Cat cleaning.
The car is not a high mileage vehicle, 47000 since new.
Always put decent fuel in it, Shell or Shell V-Power and never supermarket fuel.
I would appreciate some advice on what may be happening.
Alex
