Ok so. My a4 b7 sometimes leaks oil and coolant. It seems like the coolant leaks after i drive my car in the morning and let it sit and cool down. No codes being thrown or temp gauge moving differently then normal. Coolant level doesnt change much. I had it looked a from a vw shop and they said it is the cam gear box gasket and a coolant flange. They want to charge me $600 to fix the leaks. Anyone else come across these problems!?

 

I can't remember which forum it was on, but I do remember someone having the flange issue Seems to me if I remember correctly the flange was in the back of the engine and a pain to access.
