This bulletin applies to all 2000-2020 Audi vehicles. The engine may return to an idle speed of about 1,400 rpm although the accelerator pedal is depressed, and the vehicle hesitates/lacks power on take-off. The condition is caused by the driver... when the brake pedal and accelerator pedal are depressed at the same time.
Drivers who drive with their left foot resting on the brake pedal are prone to experiencing this condition. With the introduction of non-cable Electronic Power Control (EPC) to fuel injection systems, an engine rpm control feature has been incorporated into the engine electronic control system software.
Inform the driver of this feature.
