Hi folks.i am a virgin audi owner and i love my little a3 1.6.however i am a little concerned.i have creamy stuff on the oil filler cap.the car runs perfect no overheating or power loss.also it is not using coolant.spoke to the garage and they said give it a thrash and get it hot and do a oil and filter change and observe for two weeks.what if headgaskets goes ss i was wanting to catch it early also is the creamy substance common on these cars?he mentioned that the alloy creates condensation hence mixibg with the oil.can anyone shed some light to a .worriedauidi newbie?cheers
