runs perfect when cold?...i wonder if its fuel related........more fuel is sent to the engine when cold...abit like a choke.
Get it on vag/vcds....and checke for fault codes first and check what readings your getting on the coolant sensor,when the cars hot you should be getting a minimum of 80c.

Temp should stay at 90 all the time once car is warm.I hope not....but you may have a head gasket issue or a cylinder head issue
The only good thing here is your fan works!
oh if your cars a 8L MODEL YOUR ON THE WRONG A3 FORUM!!!!!!!!!!!
