as suggested by first members solution, i tend to agree, valve stem seals & oil & filter change.
however has your car lost power & become hard to start, ie turning over a long time on starter before engine starting,if so then it could well be piston rings.as for the most econ solution, i'm afraid i can't help as i've had no connection with audi expenses. hope i've helped in some way, best of luck, regards dj dave
