Technical Service Bulletin Improved belt tensioner in production. Service 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/18232829 39031459668 (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. Replacing the belt-driven starter-generator will not fix the problem. 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. Check for correct belt running alignment after poly V-belt and tensioner replacement as follows: 1. Run the engine at idle speed. 2. The belt must not protrude forward or backward over the roller edge of the tensioner (Figure 2, red marks). © 2024 Audi of America, Inc. Internal Page 2 of 5 All rights reserved.
