Why does the Audi auto start-stop system shake significantly?

[VonEdward]

Audi auto start-stop system shakes significantly due to: poor tire balance condition, wheel rim deformation, etc. Poor tire balance condition: If slight shaking or deviation of the car body is noticed during driving, it is generally caused by tire issues. The first possibility is poor tire balance condition, which requires the owner to perform a four-wheel alignment and dynamic balance as soon as possible. If the vehicle does not deviate, performing a tire dynamic balance will suffice. Wheel rim deformation: Another more serious condition may be caused by wheel rim deformation, which requires the owner to visit a professional repair shop for inspection. This condition generally occurs in vehicles that have been in use for a long time.
