40 Noises from front end and dash panel, rolling noises 40 17 65 2047920/1 May 24, 2017. Model(s) Year VIN Range Vehicle-Specific Equipment A4, A5, Q7 2017 - 2018 All Not Applicable Condition The customer states that there is a buzzing, booming, humming, whistling or a similar noise from the front end. The noises can possibly be heard from the area the steering or behind the dash panel. The noises may also suspected to be tire rolling noises. The noises can be reproduced in a test drive. Technical Background Mechanical damage on the wheel bearing of the front axle. Production Solution Not applicable. Service The noises from the wheel bearing can be transmitted via the steering into the vehicle interior. Because of the close proximity it can be difficult to distinguish them from tire rolling noises. Therefore with such noises check whether the wheel bearings of the front axle may be the source and replace the affected component. The following steps are helpful: 1. Does the frequency rise as the speed increases or does the sound get higher? 2. Does the noise get louder when steering? 3. Is the noise still there when slowing down? 4. Is the noise amplified on the steering wheel/airbag well? 5. Can the vibrations be felt on the unpressed coil spring when the wheel is turning? Page 1 of 3 © 2017 Audi of America, Inc.

When swapping around the wheel bearings does the noise move with a particular bearing? Tip: Please precisely locate the source of the noise with acoustic testers. It is possible that a noise perceived on the left side of vehicle is caused by the right wheel bearing. The front wheel bearings should not be replaced in pairs. If the cause of the noise cannot be traced to a wheel bearing, continue the analysis on other components. Warranty Claim Type: 110 up to 48 Months/50,000 Miles.
