2021 Audi A4-Q5 Transmission Malfunction TSB P071800

Audi has released Technical Service Bulletin (TSB) 34 22 54 2060242/2, dated March 17, 2022, to address various transmission-related concerns in certain 2021 Audi A4, A5, A6, A7, and Q5 vehicles. This bulletin supersedes TSB Group 34 number 20-48 dated August 5, 2020, and provides updated information regarding diagnosis and repair procedures for specific diagnostic trouble codes (DTCs) related to transmission performance. Owners experiencing an Audi A6 transmission fault should review this information.

Symptoms of Transmission Malfunction

Owners of affected Audi models may observe one or more of the following symptoms, indicating a potential Audi A6 transmission fault:

• The message "Transmission Malfunction" is displayed in the instrument cluster.
• The vehicle has no drive capability.
• The vehicle temporarily does not shift gears up or down.
• The message "Transmission Malfunction” message with "Journey can be continued with restrictions" is displayed in the instrument cluster.
• The vehicle enters emergency operation mode.
• The message "Reverse gear not available" is displayed in the instrument cluster.

Associated Fault Codes (DTCs)

When these symptoms occur, a technician performing a diagnostic scan may find one or more of the following Diagnostic Trouble Codes (DTCs) stored in the Transmission Control Module (TCM), also known as J217 (address word 0002):

Code	Description	Symptom Code	Status
P071800	Input/Turbine Speed Sensor "A" Circuit Intermittent	20736	Passive/Sporadic or Active/Static
P081100	Strong clutch slip	20870	Passive/Sporadic only

Important Warnings for Diagnosis

It is critical for technicians to correctly diagnose the condition of DTC P071800. If the DTC P071800 is logged as active/static, the repair procedure outlined in this TSB does not apply. In such cases, the Guided Fault Finding test plan must be completed thoroughly, and an Audi Technical Assistance Center (TAC) case should be opened for further assistance. This ensures that the correct diagnostic path is followed and prevents unnecessary repairs.

Repair Procedure Summary

For instances where DTC P071800 is logged as passive/sporadic, or for DTC P081100, the TSB outlines a specific repair process designed to restore proper transmission function and eliminate the Audi A6 transmission fault. This procedure involves replacing key transmission components and performing necessary software adaptations.

1. Component Replacement: The primary step involves replacing the gear actuator module, which is crucial for controlling gear selection. Simultaneously, the Transmission Control Module (TCM), identified as J217, must also be replaced. These replacements are critical for addressing the root cause of the fault codes and are to be performed strictly according to the detailed instructions provided in the official Elsa repair manual.
2. Control Module Test Plan and Adaptation: Following the physical replacement of the components, technicians must execute a specific "control module replacing" test plan using a compatible diagnostic scan tool. This test plan is essential for correctly integrating the new TCM with the vehicle's systems, ensuring all parameters are set accurately, and clearing any remaining fault memories.
3. Post-Repair Test Drive: A final, comprehensive test drive is mandated to verify the effectiveness of the repair. This allows the technician to confirm that the transmission operates smoothly, shifts correctly, and that the original symptoms and fault codes, including the Audi A6 transmission fault, have been completely resolved.

Affected Transmissions

This TSB applies to vehicles equipped with various transmission types, depending on the model. These include:

• OCK Transmission
• OCL Transmission
• OCJ Transmission
• OHL Transmission
• ODK Transmission

Required Parts and Tools

The successful completion of this transmission repair, as detailed in TSB 34 22 54 2060242/2, necessitates a comprehensive inventory of specific parts and a range of specialized tools. Technicians are advised to always consult ETKA and their dealership's Parts Department for the most current information, including any updated part bulletins, as part numbers can evolve.

Key Replacement Parts: The required parts list is extensive and varies slightly depending on the specific transmission type (e.g., OCK, ODK). It includes numerous gaskets, such as 0CK301463A (gasket for housing), 0CK301164 (gasket), and 0CK325446 (gasket), ensuring proper sealing after disassembly. Various bolts, including N 91043601 (hex socket head bolt) and N 10801101 (hexagon socket flat head bolt), are also specified for secure reassembly. O-rings like WHT006777 (O-ring for accumulator) and WHT 009 273 (O-ring) are essential for maintaining fluid integrity. Crucially, the control unit for the automatic gearbox (Order to VIN) and specific transmission fluids, such as Dual Clutch Gearbox Oil ATF (G 055529A2) and Transmission oil MTF (G 052549A2), are vital for the repair.

Specialized Tools: The complexity of the transmission repair demands a suite of specialized tools to ensure precision and safety. These tools include, but are not limited to:

• Lifting and Support Equipment: VAS6100 (Shop Crane), T40123A with T40123/2 (Dual Clutch Lifting Device with sleeve), 10-222A/2 (Engine Support Bridge - Additional Hooks), 10-222A/12 (Engine/Gearbox Support Shackle), and T40321 (Support) are used for safe handling and positioning of the transmission and engine.
• Measurement and Assembly Tools: T40099 (Pressure Stand), T40100 (Ruler), VAS6087 (Digital Depth Gauge), T40323 (Press Tool), T40305 (Assembly Tool), T40199 (Oil Sump Assembly Pin), and VAS6122 (Engine Bung Set) are necessary for precise measurements and component assembly.
• Removal and Installation Aids: T40288 (Guide Pins - Gearbox), VW771 (Slide Hammer Set), T40155 (Retaining Strap), and VW637/2 (Puller - Grease Cap) facilitate the removal and installation of various transmission components.
• Heating Equipment: VAS1978/14A (Hot Air Blower) is also listed, likely for specific heating requirements during the repair process.

For vehicles equipped with the ODK transmission, particularly PHEV models, additional specialized tools such as T40412 (Assembly Tool) and T40410 (Lifting Device) are specifically required, highlighting the unique requirements of these variants.
