Bulletin Summary
Audi is releasing a software calibration update to the Approved Emissions Modification (AEM). This software calibration will include the following changes to the vehicles' emissions control and on-board diagnostics (OBD) software: (1) It will correct an issue that is causing the 'check engine' light to falsely illuminate under certain driving conditions, which has resulted in replacement of the diesel oxidation catalyst (DOC) for certain customers; (2) It will reduce the likelihood of experiencing an engine shudder that could occur during certain warm-up driving conditions; and (3) It will improve OBD monitoring of vehicle emissions systems and otherwise improve the software used by your vehicle.
About Technical Service Bulletins
A Technical Service Bulletin (TSB) is a document issued by a vehicle manufacturer to its dealers, describing a known issue with a specific vehicle or set of vehicles and the recommended procedure to fix it. Unlike recalls, TSBs are not mandatory and are typically only performed if an owner reports the related issue. However, TSBs can be an indicator of common problems with a vehicle.
