June 4 2016 my vehicle stalled while driving on the freeway. Per Audi dealer the cause is engine failure as the oil pump has a tendency to go bad causing no compression in the engine. The vehicle used synthetic oil and had its oil changed frequently including having to add additional oil as it was burning through oil quickly which appears to be common in these vehicles. The camshaft also needed replacing within one year after purchasing the vehicle. There is a fault in the engines and such breakdowns should not occur. Audi has quoted $14000 to fix and offered no financial support or further explanation.
