I have a G80 Sport....I have noticed after I drive a while, half hour or 2 hours, and park with engine running I open the a door and I can smell is what smells like anti-freeze. I had the dealer look into this and cannot find any leaking. The temp. gauge just under half mark. Dealer said it is from the turbos. I cant figure out how they would smell like that when you are just sitting still Idling. I have set for 1 minute and 10 minutes and get the same result. Anybody else smell this?
