How long had it been burning oil for? Did you ask them to cover more of the cost?My 2011 A5 2.0T was eating 1 Litre of oil every 150 Kilometers (had to buy 1L of oil every every 2 days). Plumes of smoke would come out of the exhaust after about half an hour of driving (I guess the cat was burning off the oil).
Odometer was 95000km
Brought the car back to the Audi Dealer where I bought it from 3 years ago (2nd hand) and it went through the usual tests, and failed miserably.
They ended up replacing the pistons, piston rings, engine block (cylinders were scored too much), and some other parts. They said the total repair was around $16000 but Audi Australia said they will cover most of the cost, I ended up paying around $4000.
Its been fine since then. The oil light hasn't come on for 8 months..
