2022-2024 Audi/VW Control Unit Software Update SM 38-2023

Audi and Volkswagen have issued Special Notice SM 38-2023, a Parts Circular directed at dealerships. This notice outlines a process for managing inventory of a specific control unit to ensure that only the most current versions are available for installation in vehicles. This is not a recall for a specific defect but rather an update to the parts supply chain.

The purpose of this notice is to improve the quality of parts reaching customers by ensuring that only control units with the latest software development are stocked. Owners of affected models, such as the 2022-2023 Audi A3 or 2024 Volkswagen Atlas and Atlas Cross Sport, should be aware that any replacement control units should have the updated software.

Affected Control Unit and Software Versions

Special Notice SM 38-2023 specifically targets the control unit identified by the part number 5WA-907-556-G. The key criterion for return is the software version. Only parts with software version SW: 00304 or greater are considered to be at the latest state of development. All previous software versions of this control unit are affected and must be returned by dealers.

Other identifiers associated with this control unit include 5WA 907 556 D H31, manufacturer FICOSA, and additional codes like 61986095 and FZ6-S2023.06.2300012643. The notice emphasizes that dealers must ensure they are stocking and installing the most current version of this part, which includes the updated Audi A3 control unit software 00304.

Why This Matters for Owners

While this Special Notice SM 38-2023 is primarily for dealers, it indirectly benefits vehicle owners. By ensuring that dealerships only stock and install the latest software versions of the 5WA-907-556-G control unit, Audi and Volkswagen aim to provide the best possible service and part quality. If your vehicle requires a replacement of this control unit, this directive helps guarantee that you receive a part with the most up-to-date software, potentially preventing future issues or ensuring optimal performance.

Important Dealer Instructions and Deadlines

The Parts Circular includes several critical instructions and deadlines for dealerships regarding the return of these control units:

• "Please return your inventory of the above-listed material numbers to your facing PDC, no later than 8/24/2023."
• "Only parts with software version SW: 00304 or greater correspond to the latest state of development. Previous versions are affected and must be returned."
• "Items returned after the above-mentioned date WILL NOT be accepted on any type of return/buyback."
• "Please re-order required new materials using the same part number."

These instructions highlight the urgency and strict policy surrounding the inventory update for the Audi A3 control unit software 00304 and related vehicles.

Dealer Return Process Overview

For dealers, the process involves several steps to ensure proper credit and inventory management. This includes filing a separate "Claim with Return" using the Special Notice Number and Parts Circular number, reviewing "Parts On Command" for delivery documents, and correctly labeling packages with a YELLOW DEPOT REQUEST RETURN label. A copy of the Delivery Document must be included with the returned parts. This structured approach helps streamline the return of outdated control units.
