Audi A4 2.0 2001 model B6
I have had the problem of burning too much oil, so I did a little test to see how often I have been toping up my oil. It turns out I am managing to do about 230 miles before I need to top up. The car has done 100.000 miles now and it was a company car before I bought it.
Anyway I have taken it to AUDI and they are stripping the engine to find out what it could be at a cost of £400 just for looking at it, and then what ever it cost's to repair.. I reckon it might be the piston rings but who knows what crap they come out with to rip me off. Fingers cross and will get back to you shortly..
