In hot days or simply when in heavy traffic my 'BHZ' S3 suffers some serous heat soak.
I imagine other owners of the same car can tesdtify, right?
Was looking in to thermostats, searching for cooler-opening ones, but I found none.
The only part I came across is from Neuspeed, but is made for the older Golf.
Did anyone of you manage to address this problem?
