I went to get my A4 fixed for the exhaust fumes with heater on and found out it was only a $78 breather hose I was told by a Audi tech that it was most likely a oil leak that would hit the pipes in the engine and then cause the smell in the cabin. But after they put die into my oil there was no leak and after they looked around they found the breather hose was broken. It is nice to get a cheap fix for once. thank to all the input from everyone while I was trying to figure this out.
