Hi,

This is my first post here. I just purchased a 2008 Audi TT 2.0T in February 2016. I noticed it was burning a lot of oil. I researched a bit and found that 0.5L/1000km is the limit and did a rough estimate and found that I was most likely over the limit. I then went to the Audi dealership that my car had a history with and requested an oil consumption test, which it then failed - .89L/1000km.

When I bought the car it was still covered by an extended warranty so they agreed to cover the repair which would involve replacing the piston rings. The only issue is that if they take the engine apart and find that the damage was caused by something getting past the air filter and damaging the cylinder wall then I will be on the hook for the cost of repair which of course by then will be very expensive and possibly require a new engine. Does this sound reasonable? Is it common for something to bypass the air filter and damage the cylinder? I haven't read of something like that happening, from what I've read it's been mostly poor tolerance issues. Should I be concerned? I did ask about a pre-inspection using a endoscope but the answer was that it would cost more and I might have to pay for it regardless of the what it tells me. Would the endoscope test be worth the extra money?

Thank you for any insight or answers to the questions,
Dave
