Customer states:
Squeaking noises are heard when the steering wheel is turned or maneuvered. The noises may be more
prevalent in wet weather.
Technical Background
The folds of the outer rubber boots on the front axle shafts may come in contact with each other when the
steering wheel is turned, causing squeaking noises. These noises are more likely to occur when the vehicle is
new. The volume and occurrence of the noise will dissipate after a short break-in period.
Production Solution
Not Applicable.
Service
This is a normal condition. Explain the Technical Background to the customer.
Do not replace any parts, as replacing parts will not correct the concern. Needlessly replaced parts will be
debited.
Warranty
This TSB is informational only and not applicable to any Audi warranty.
