Hi, recently bought a brand new A4 Black edition - Automatic 35tsfi model. noticed slow acceleration, engine revs high when changing gear. phoned Audi dealership and they advised to contact Audi Roadside Assistance. Roadside Assistance came out and did a diagnosis check and 6 mile road test and found no faults and said vehicle was okay Since then car now appears to have more acceleration, but engine idle is more noisy and slight vibration in the engine and car
