Service bulletin TB011420
A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

| Dealer 23EP | 2023-11-06. Service bulletin. Vehicles included in this action have been identified as having received the Diesel Approved Emissions Modification (AEM). Volkswagen dealers will inspect the software level on the vehicle's Engine Control Module (ECM) to ensure that the AEM software level is current. If a software discrepancy is found, the ECM software will be updated free of charge. Please note that the ECM software check will automatically result in a check of the Transmission Control Module (TCM) software level, which would also be updated to the AEM level, if a software discrepancy is found. Only in the event that current software is not found on a vehicle, there could be an impact on vehicle tailpipe emissions. |
