Technical Service Bulletin 26 Creaking noises are heard from exhaust flap at idle speed - V6 2.9TFSI 26 24 51 2062029/3 February 20, 2024. Supersedes Technical Service Bulletin Group 26 number 21-46 dated May 18, 2021 for reasons listed below. Model(s) Year RS 5 2018 – 2024 RS 5 Sportback 2019 – 2024 VIN Range Vehicle-Specific Equipment All Not Applicable Condition REVISION HISTORY Revision Date Purpose 3 - Revised header (Added MY23, 24) 2 05/18/2021 Revised header (Added RS 6 and RS 7) Revised Condition (Updated Customer statement) Revised Technical Background (Added information) Revised Service (Added information) 1 02/01/2021 Initial publication Customer states: • There are creaking noises from the exhaust system, from the exhaust flaps (with engine idling/when changing gear/maneuvering). • The exhaust flap may open/close several times independently. Workshop findings: • A flap/motor operating noise can be heard from the rear silencer when the exhaust flaps are activated. Technical Background The exhaust flap system is a mechanical system that is exposed to significant influences due to weather, thermodynamics and other environmental conditions which may affect the flap mechanism and the noise emitted from the area of the rear silencer. Although these influences can cause noises that may be heard inside or in the vicinity of the vehicle, this is due to technical design and is not a cause for concern. If the exhaust flap opens and closes several times independently while you are using the vehicle, this is part of a functional check of the exhaust flap mechanism that is initiated by the software. While the vehicle is being operated, the ECM may detect friction on the exhaust flap mechanism. A “loosening” function is implemented in many models to overcome this type of friction which may occur suddenly (self-rectification). This can be seen by © 2024 Audi of America, Inc.

Technical Service Bulletin the exhaust flap being activated several times in a row during an operating cycle. The customer may notice this happening in some cases. Production Solution Not applicable. Service Explain the Technical Background to the customer if necessary. 1. Evaluate the customer concern by comparing it with the video located at: https://audiexternal.kzoplatform.com/player/medium/1872019322604361204 (Figure 1). Figure 1. QR code for viewing the supporting video. 2. The noise can be compared by following the sequence below: • Engine idling. • Drive select mode: dynamic. • Shift selector lever from P to D and N. 3. When shifting, the exhaust flap is activated and opens or closes, providing the best opportunity to check the normal operating noise of the exhaust flaps. 4. • During diagnosis, please note: • Drivability issues may occur if the flap motors are disconnected, and/or are causing the DTCs. • If the control motor and exhaust flap noise is found comparable to the audio file, then the concern is not valid, and the noise is normal operation. In this case do not replace any components and explain to the customer that this sound is normal and caused by the operation of the exhaust flaps. The vehicle can be released to the customer. © 2024 Audi of America, Inc. Internal Page 2 of 3 All rights reserved.
