What causes steering wheel vibration in an Audi Q7 at idle?
1 Answers
Audi Q7 steering wheel vibration at idle is generally caused by excessively high or low idle speed. When the idle speed is too high or too low, the engine's operating frequency reaches the vehicle's resonance point, transmitting vibrations to the body and resulting in noticeable steering wheel vibration. In such cases, it is advisable to inspect the vehicle's engine spark plugs and ignition coils, followed by cleaning the throttle body and fuel injectors. Taking the 2021 Audi Q7 as an example, it is a mid-to-large-sized SUV with dimensions of 5067mm in length, 1970mm in width, and 1731mm in height, featuring a wheelbase of 2996mm and equipped with a 2.0-liter turbocharged engine.
