Came out to the car last Sunday to find a puddle of oil under the car.. Looked at the dipstick and no oil registered. Didn't trust driving it to the nearest Audi dealer (9 miles) so had the hook come and get it. Turns out the problem was something called an oil separator (possibly in the cam adjuster area?). The write-up indicated the "cam adjusters froze causing undue oil pressure". This caused the oil to damage the gaskets and caused a major leak.
Anyone know what an oil separator is what it does in the context of the cam adjuster mechanism?
