apparently ALL gti's do this as it is a fault with the fans that VW never botherd correcting
i think its because there a 2 fans, a small one and a large one, the large one is only ment to run when its very hot and the small one for traffic jams and such, and they are ment to run seperate, but both run together,
dont quote me on this but its something like that and it IS a known fault
