2025 Audi A5 KD2 Software Update Irregularities TSB

Symptoms

Owners of 2025 Audi A5, S5, Q5, and SQ5 vehicles may not directly notice symptoms, as this issue is typically identified by technicians during a KD2 combined software update. The update process, specifically the "00 Combined software update 03.10.00/C (28.13.01) KD2", can lead to various diagnostic messages appearing in ODIS-S and communication loss with the reversing camera system control unit. These irregularities prevent the successful completion of the 2025 Audi A5 KD2 software update.

Fault Codes / DTCs

When performing the KD2 combined software update, the following messages may appear in ODIS-S, relating to diagnostic addresses 8117 and 006C:

• 8060
• 8118
• 8125
• 8090
• SDB20F0E

Additionally, the following event memory entries (DTCs) may be logged in the control unit for data bus diagnostic interface -J1273- (diagnostic address 0019):

• U171400: Rearview Camera System Control Module, no communication on Ethernet data bus (symptom 4556)
• U171400: Rear peripheral camera control module No communication on Ethernet data bus (symptom 4557)

After these messages appear, the reversing camera system control unit -J772- (diagnostic address 8117) may no longer be reachable via ODIS-S, and diagnostic address 8117 will no longer be shown.

Diagnosis / Trigger Conditions

This condition arises during the KD2 combined software update. The overhead view camera control unit -J928- (diagnostic address 006C) enters bootloader mode, which prevents it from performing its master function. Consequently, the reversing camera system control unit -J772- (diagnostic address 8117) also becomes unavailable. This technical background explains why the 2025 Audi A5 KD2 software update encounters these issues, leading to diagnostic irregularities.

Repair Procedure

To address the irregularities during the KD2 combined software update, technicians should first check the code of the control unit for the overhead view camera -J928- (diagnostic address 006C) using ODIS-S or by reviewing the diagnostic log. If the code "000000" is logged for -J928-, it indicates that replacement of this control unit is necessary.

It is essential to refer to the instructions provided in ETKA and TSB 2078367, titled "91 Replacing reversing camera system control unit J772 + control unit for overhead view camera J928; Reference 2078219," for the detailed replacement procedure of both the reversing camera system control unit -J772- and the overhead view camera control unit -J928-.
