I just got back from a 2,500 km road trip with my 2012 Sportwagen TDI DSG. Went to check the oil today, and everywhere on the top of the engine, in behind the headlights on both sides, the firewall, etc is all coated in oil. I had no indication of this when I was driving, no smell, nothing. I'm 99% sure it's not engine oil, as it's a light brown, and my oil is where it should be. So that leaves transmission oil, or? I lifted the air box out to see if I could see trans oil there, there was some, but no more than anywhere else. It must have to be a fine mist because it is EVERYWHERE. Any thoughts as to where to start digging for a transmission oil leak? I haven't popped the skid plate off yet (I have a steel one) and a guy can't exactly just check the transmission fluid level. Could it be AC oil if my condensor exploded or something? Anyone experience anything like this before? Thanks!
