MY oil leak, which at first I thought was a oil line, turns out to be the cooler itself. One of the oil lines "sawed" through the cooler on the inboard cap. Is the cooler a Ur-q only part or is it used on a few diffren Audi models? I would love to get the car running today , I miss it, and if I can find one at the local wrecking yard? Cheers, Jim Hahn
