Audi A8 Quattro chirping sound increases when accelerator is released after driving on Audi A8 Quattro

Some Audi A8 Quattro owners report experiencing a chirping sound that increases when the accelerator is released after driving. This issue may stem from a failing drive belt idler pulley, which can produce an audible chirping noise due to a worn pulley bearing. Additionally, a dirty or damaged CV axle can also lead to similar chirping sounds, particularly upon releasing the accelerator. An incorrect RPM indicator may contribute to these noises as well, indicating potential malfunctions in the vehicle's systems. Furthermore, owners have noted that clipped or irregularly worn tires can generate chirping noises that become more pronounced when the accelerator is disengaged. It is recommended that affected owners have their drive belt idler pulley, CV axle, RPM indicator, and tires inspected by a qualified mechanic to promptly address the issue and prevent further damage to the vehicle.
