My vehicle suffered loss of power and as a result too much of hesitation, it behaved as if it is about to stop on highway.it is a new car and thought it could be bad gas, changed gas station made sure gas is not an issue and hesitation/loss of power continues. I was about to schedule an appointment for service but dealer called me saying my car's VIN number has been listed for an imp update in order to prevent failure of certain components and people in germany are looking forward to get this fixed asap I.e ; 18 Sept 2015. I scheduled an appointment on 24 Sept 2015 it is not just update but the entire turbo is replaced, month later car is having similar symptoms, no power/hesitation, intermittently stuttering or misfiring. Audi mechanics kept car for a day (13 Nov 2014)and replied they couldn't find the issue and returned the car back to me. I assured them the vehicle had premium gas only and nothing else. I will keep you informed of the status.
