Hi have you taken the car to your audi centre was ther any faults stored in the engine ECU? If not I would suggest looking to see when the fuel filter and air filters where last replaced failing that check the acctuator rod on the turbine make sure it moves nice and freely and is not jammed let me know how you get on cheers
