2022-2023 Audi A6/A7 Abrupt Shifting Behavior TSB

Owners of 2022-2023 Audi A6, A6 allroad, and A7 models may experience an Audi A6 abrupt shifting sensation, specifically described as the transmission feeling "rough" or "abrupt" when shifting to a higher gear. This condition is addressed by Audi Technical Service Bulletin (TSB) 37 24 30 2075033/2, which supersedes an earlier bulletin, Group 37 number 24-26, dated October 8, 2024.

Symptoms

If you own a 2022-2023 Audi A6, A6 allroad, or A7 with the DL382 transmission, you might notice the following symptom:

• "Shifting to a higher gear feels 'rough' or 'abrupt'"

It's important to note that when this Audi A6 abrupt shifting occurs, technicians typically find no relevant event memory entries or diagnostic trouble codes (DTCs) logged in the gearbox control unit, making it a purely experiential symptom for the driver.

Diagnosis / Trigger Conditions

To confirm this issue, a technician will attempt to reproduce the customer's complaint of "rough" or "abrupt" shifting behavior. The TSB emphasizes that the repair should only be performed if the condition is consistently reproducible and matches the description.

Repair Procedure Summary

The core of the repair involves updating the software for the Transmission Electronics control module, also known as J217 (diagnostic address 0002). This software update aims to resolve the internal software issue within the gearbox control unit that causes the Audi A6 abrupt shifting.

After the software update, various other control units in the vehicle must be reconfigured to ensure they function correctly with the newly updated gearbox control unit. This process requires using the SVM (Software Version Management) system with SVM code 02A230. Technicians are instructed to follow all guidelines outlined in TSB 2011732, which covers general software version management operating instructions.

Required Tools or Parts

For this software update, specific software part numbers are involved:

• Old Software Part Number: 4K0927153BT
• Old Software Version: 0002
• New Software Part Number: 4K0927153DH
• New Software Version: >0001

Technicians must use Diagnostics over Internet Protocol (DoIP) when flashing control modules via ODIS (Offboard Diagnostic Information System). To activate DoIP, the technician needs to navigate to Administration >> General >> GFF Process >> DoIP communication >> Only allow DoIP communication. A red LED on the VAS 6154(A) diagnostic tool indicates when DoIP is active.

Important Warnings for Owners and Technicians

Audi has issued several critical warnings regarding this service bulletin:

• Non-Genuine Components: "If non-genuine retrofits or modifications have been carried out on the vehicle by third parties, neither AUDI AG nor your own company will accept liability for any damage that may be caused by updating the software, or by failing to do so." Owners should disclose any aftermarket modifications to their service center.
• Warranty Claims: "The following repair must only be carried out if all the criteria (model/type, chassis number, engine/motor and gearbox code, PR number(s), part number, software version, code etc.) apply exactly. Otherwise, this solution will not eliminate the problem, and repeat repairs may be necessary. In such a case, we may reject the warranty claim and charge back the cost of the parts."
• Warranty Coverage: "If the vehicle is outside of any warranty, this Technical Service Bulletin is informational only." This indicates that out-of-warranty repairs for this issue may not be covered free of charge.
