I have a 1999 S4, 182k miles. Still original turbos. It has an oil leak of sorts for years but not too bad. Recently it has got worse. No oil is deposited on the ground when parked up but come out 'on the move', or 'under load/pressure'. Slight leakage found round turbos upon brief investigation. This worsening has coincided (maybe unrelated) with an intermittent grumbling under load and the car is help back - like when a lambda sensor goes. There are no fault lights coming up, and I am yet to have a diagnostic test. Does this kind of thing ring a bell with anyone? I have had the car for 145k so know it pretty well and love it even more and had a failed lambda at 38k, with no fault lights, but this did not produce the odd rumblings or oil drippage. Thank you in advance.
