2021-2024 Audi Gearbox Malfunction TSB 2067653/8

Owners of 2021-2024 Audi A4, A5, A6, A7, and Q5 models may encounter various transmission-related issues, often indicated by a "Gearbox Malfunction" message in the instrument cluster. This Technical Service Bulletin (TSB) 34 24 69 2067653/8, which supersedes TSB 24-68, details the diagnostic and repair process for these concerns, particularly when specific Diagnostic Trouble Codes (DTCs) are present.

This TSB is crucial for addressing conditions such as the vehicle having no power, intermittent shifting problems, or entering limp home mode. Understanding the symptoms and associated fault codes is the first step in resolving these complex transmission issues.

Symptoms of a Gearbox Malfunction

If your Audi is experiencing a gearbox malfunction, you might observe one or more of the following symptoms:

• A warning message, "Gearbox Malfunction", displayed in the instrument cluster.
• The vehicle may have no power or exhibit reduced performance.
• Intermittent issues with the vehicle not shifting up or down correctly.
• The vehicle entering a "limp home mode", limiting its speed and functionality.
• A message stating "Reverse gear unavailable" appearing in the instrument cluster.
• A notification indicating "You can continue driving (functions limited)" in the instrument cluster.

These symptoms are often accompanied by specific fault codes stored in the transmission control module (TCM), J217.

Associated Fault Codes (DTCs)

When diagnosing a gearbox malfunction, technicians will look for specific DTCs stored in the transmission control module (J217, address word 0002). The TSB identifies the following codes:

DTC Code	Description	Symptom Code
P071800	"Input/Turbine Speed Sensor 'A' Circuit Intermittent"	20736
P276800	"Input/Turbine Shaft Speed Sensor 'B' Circuit Intermittent"	20737
278700	"Clutch Temperature too High"	20882
P081100	"Excessive Clutch Slippage"	20870
P081E00	"Clutch 2 excessive clutch slippage"	20872

These codes indicate specific issues within the transmission system, often related to sensor performance or clutch operation, contributing to the Audi gearbox malfunction P071800 or similar issues.

Important Transmission Production Date Range

Owners should be aware: This TSB applies only to transmissions manufactured within a specific date range. If your transmission's manufacturing date falls outside of June 15, 2020, and November 30, 2023, this TSB does not apply to your vehicle's issue. Technicians must first determine the transmission's production date by checking data stamps located on the front differential and bell housing (as shown in Figure 1 of the original TSB document).

Diagnosis and Repair Procedure

The repair procedure outlined in TSB 34 24 69 2067653/8 involves a precise diagnostic flow:

1. Reproduce the Complaint: The technician will attempt to confirm the customer's reported symptoms.
2. Check Transmission Production Date: Verify the transmission was built between June 15, 2020, and November 30, 2023.
3. DTC Analysis: The key to diagnosis lies in the status of the DTCs:
   • If DTC P071800 ("Input/Turbine Speed Sensor 'A' Circuit Intermittent") is stored as active/static, this TSB does not apply. The technician must follow the ODIS test plan for further diagnosis.
   • If DTC P071800 is stored as passive/sporadic, the repair involves replacing the transmission control unit J217 according to the Workshop Manual.
   • Similarly, if DTC P276800 ("Input/Turbine Shaft Speed Sensor 'B' Circuit Intermittent") is stored as active/static, this TSB does not apply, and the ODIS test plan should be followed.
   • If DTC P276800 is stored as passive/sporadic, the transmission control unit J217 should be replaced.
   • If DTC 278700 ("Clutch Temperature too High") is logged as passive/sporadic, the transmission control unit J217 should also be replaced.

After replacing the control unit, technicians are instructed to use the "Replace control module" test program and conduct a test drive to confirm the repair has resolved the Audi gearbox malfunction P071800 or other related issues.
