Technical Service Bulletin Scenario 1: Grinding, squeaking, or tweeting noises 1. Let the engine run at idle speed and assess the noise. An example of the noise can be found in the following video: https://audiexternal.kzoplatform.com/player/medium/1823282939031459668 (Figure 1). Figure 1. QR code for supporting video. 2. For final confirmation of the source of the noise, spray the inside of the poly V-belt with a little tap water. One spray blast out of a commercially available water spray bottle is enough. The noise should disappear as a result. 3. If the noise disappears after spraying with water, replace the poly V-belt and belt tensioner. If a new belt tensioner has already been installed, do not replace it again. Scenario 2: Poly V-belt damaged or fallen off 1. Replace the belt tensioner and poly V-belt. If a new belt tensioner has already been installed, do not replace it again. Page 3 of 7 © 2022 Audi of America, Inc. All rights reserved.
