Our daughter's 2009 A4 CPO was part of the oil consumption problem. Audi replaced the bottom half of the engine around 60,000. Car was maintained according to their directions. Now at 114,000 miles the tensioner failed and the timing chain broke and threw shards of metal throughout the engine. She still has $8,000 left to pay on the loan and they are telling her it will be $12,000 to replace the engine. Got Audi corporate involved and they are acting like they are helping, but spoke to the dealer and Audi is putting it on them. They are trying to find a used engine and will charge us $6,000. Ugh any solutions out there?
