2025 Audi A5/Q5/S5 Gearbox Warning Lamp with DTC P060A00

Owners of certain 2025 Audi A5, Q5, and S5 models may experience a "gearbox warning lamp" illuminating in the instrument cluster, often accompanied by a "drive system fault". This issue is addressed by Audi Technical Service Bulletin (TSB) 2080077/3, which outlines a software update to correct underlying control module malfunctions. This bulletin, released on January 30, 2026, is the third revision of this guidance.

This TSB 2080077/3 supersedes the previous PSS TSB 2079003 and provides updated guidance for technicians. The primary fix involves performing a combined software update for various control units in the vehicle, specifically referencing TSB 2079690 for the detailed procedure.

Symptoms of the Gearbox Warning Lamp and Drive System Fault

Owners typically report seeing the "gearbox warning lamp" light up in the instrument cluster. This warning indicates a potential issue with the vehicle's transmission or drive system. The presence of this lamp often signals a "drive system fault" which can affect vehicle performance.

In some cases, the diagnostic trouble codes (DTCs) associated with this issue may be present in the vehicle's systems even without an active customer complaint. These codes are often discovered by technicians during routine diagnostics or when investigating other, unrelated complaints. The primary concern for owners is the illuminated Audi gearbox warning lamp P060A00.

Diagnostic Trouble Codes (DTCs)

When diagnosing the "gearbox warning lamp" and "drive system fault", technicians may find specific diagnostic trouble codes (DTCs) logged in the vehicle's control units. These codes pinpoint the exact nature of the control module malfunction.

Code	Description	Symptom Number	Control Unit / Diagnostic Address
P060A00	Control module internal processor monitoring malfunction	20899	J217 (0002)
P1FD700	Transmission control module warning light request active	385025	J1312 (812C)

Specifically, DTC P060A00, indicating a "Control module internal processor monitoring malfunction", is logged in the transmission electronics control unit J217 (diagnostic address 0002). Concurrently, DTC P1FD700, which signifies "Transmission control module warning light request active", is logged in the control unit for drive system and running gear functions J1312 (diagnostic address 812C). Both codes are critical indicators of the issue leading to the Audi gearbox warning lamp P060A00.

Diagnosis and Trigger Conditions

To properly diagnose and address the "Audi gearbox warning lamp P060A00" issue, technicians are instructed to first attempt to reproduce the customer complaint. This helps confirm the presence of the fault and ensures the correct repair path is followed.

The repair outlined in TSB 2080077/3 should only be carried out if all specified criteria are met. These criteria include the exact model and type of vehicle (A5, S5 (FU), Q5, Q5 Sportback, SQ5, and SQ5 Sportback (GU)), the specific VIN range (all up to CW 36/25 for 2025 models), and other vehicle-specific equipment, engine/motor, gearbox code, PR number(s), part number, and software version. Failing to adhere to these precise criteria may result in the problem persisting, requiring repeat repairs, and potentially leading to warranty claim rejections where the cost of parts may be charged back to the dealer.

Important Warnings for Owners and Technicians

Audi has issued specific warnings to ensure the correct and effective resolution of this issue:

• Do not replace hardware components without proper diagnosis. The bulletin explicitly states: "Otherwise, this solution will not eliminate the problem and repeat repairs may be necessary. In such a case, the warranty claim may be rejected, and the cost of the parts may be charged back." This prevents unnecessary part replacements and associated costs.
• Remove all electronic auxiliary equipment from the vehicle before performing the software update. This includes devices such as electronic tachographs connected to the OBD socket. Audi warns that "This equipment could have an impact on the vehicle electronics, triggering this complaint." Ensuring a clean diagnostic environment is crucial for a successful software update.

Repair Procedure Summary: Software Update

The resolution for the "Audi gearbox warning lamp P060A00" and P1FD700 DTCs involves performing a combined software update for various control units. This update is not performed in isolation but is part of a broader software optimization strategy.

The specific software update required is detailed in a separate document, TSB 2079690, titled "00 Combined software update 03.10.00/C (28.13.01) KD2". Technicians are instructed to perform this update. The optimized software is available from week 36/2025. This software update is designed to correct the internal processor monitoring malfunction and the active warning light request, thereby resolving the "gearbox warning lamp" and "drive system fault" conditions.

Warranty Information and Labor Operations

For vehicles still under warranty, this Technical Service Bulletin 2080077/3 provides specific guidelines for submitting claims to Audi. If the vehicle is outside of any warranty, this Technical Service Bulletin is informational only, meaning the repair may not be covered by Audi.

• Service Number: 3410
• Damage Code: KD02
• Claim Comment: As per TSB 2080077/3

The following labor operations are specified for warranty claims:

• 0151 0010: This operation covers the software update itself, including the necessary step of connecting a battery charger to maintain stable voltage during the process. Technicians should refer to the Standard Repair Time (SRT) for associated operations.
• 0151 0040: This is a fixed-rate operation for the software update, encompassing all required preliminary and follow-up work. This includes critical steps such as the bus sleep cycle, calibration drives, and any additional work needed to complete the update successfully. This operation is allotted 130 Technical Units (TU).
• 0150 9999: In cases where additional attempts are required due to flash cancellation, an additional lump sum of 50 TU is possible per documented attempt.

All warranty claims submitted for payment must strictly adhere to the Audi Warranty Policies and Procedures Manual. Audi Warranty reserves the right to review or audit any submitted claims. A key benefit for technicians performing this combined software update is that time stamps are not required for billing under warranty, allowing them to work on other vehicles concurrently. Furthermore, this specific software update can also be performed by non-productive personnel, streamlining the service process.
