2022-2026 Audi A/C Compressor Replacement GFF Test Plan TSB

Audi has issued Technical Service Bulletin (TSB) 82 24 00 2041717/10 to clarify the mandatory procedure for any Audi A/C compressor replacement. This bulletin, dated July 11, 2024, supersedes previous guidance (TSB Group 87 number 23-45 dated July 19, 2023) and applies to all Audi vehicles from model years 2022 through 2026 that require an A/C compressor replacement.

The core requirement is the completion of an ODIS GFF cooling performance test plan, specifically the Function Test Log version, whenever an A/C compressor is replaced. This process ensures proper diagnosis and documentation of the recovered refrigerant volume, which is mandatory without exception.

What This TSB Addresses

This TSB emphasizes that regardless of the reason for failure, an Audi A/C compressor replacement must be accompanied by a specific diagnostic procedure. The ODIS GFF (Guided Functions Framework) test plan is a critical step to confirm the A/C system's performance and to document the refrigerant recovery process. This ensures that repairs are conducted thoroughly and that environmental regulations regarding refrigerant handling are met.

Diagnosis Procedure: The ODIS GFF Test Plan

Before any Audi A/C compressor replacement, technicians must run the ODIS GFF test plan. The exact navigation path within the ODIS diagnosis program can vary based on the vehicle and its equipment level. The A/C cooling performance test is categorized as a 'function test' and can typically be found under 'functions', 'other functions', or 'general function tests'.

Here are example navigation paths:

• For vehicles with 08 - Heating and Air Conditioning Electronics:

  1. Navigate to the Guided Functions tab in the diagnosis program.
  2. Select '08 – Front A/C display control head -E87-' then '08 Heating/Air Conditioning Electronics, functions' and finally '08-Other Functions'. Alternatively:
  3. Go to the Test plan tab of the diagnosis program.
  4. Select 'Body' >> 'Heating / Air Conditioning' >> '01 – On Board Diagnostic (OBD) capable systems' >> '08 Climatronic control module, functions J255' >> '08-General function tests'.

• For BEV Vehicles with C5 - Thermal Management Control Module:

  1. Navigate to 'Diagnostic capable system' >> '00C5 - Thermal Management Control Module -J1024-' >> '00C5 - Thermal management control module, functions' >> '00C5 - Basic Setting' >> '00C5 - Basic setting complete'.

• For PHEV Vehicles with C5 - Thermal Management Control Module:

  1. Navigate to 'Body' >> 'Heating / Air Conditioning' >> '01 - On Board Diagnostic (OBD) capable systems' >> 'C5 Thermal Management Control Module -J1024-' >> '00C5 – Thermal management control module, functions' >> '00C5 - Basic Setting' >> '00C5 - Basic setting complete'.

Once the function test has been added to the list of "Tests in current test plan", technicians should select "Vehicle is not cooling". The cooling system performance test plan can then be completed by following the prompts provided by the ODIS system.

Important Notes and Documentation Requirements

• Test Results: If the A/C performance test returns "No malfunctions", then no repairs are needed, indicating the system is operating properly. If the test returns a malfunction, further diagnosis and repair are required.
• Documentation: If the compressor is determined to be faulty and is replaced, it is mandatory to upload a final protocol of the Diagnostic Log to GFF Paperless. Additionally, the "Function Test" version of the diagnostic log must be printed out and attached to the replaced compressor for return to the WPRC (Warranty Parts Return Center). It is not necessary to print the complete diagnostic log; only the test plan section is required.
• ODIS Feedback: The location of the cooling performance test plan can vary. If the test plan is missing or cannot be found in ODIS, technicians are instructed to file an ODIS Feedback. This requirement for the test plan is not waived due to navigation difficulties.
• Related Bulletins: Other applicable bulletins still apply. Specifically, TSB 2035582: 87 A/C compressor replacement provides additional information on required documentation of recovered refrigerant volume for vehicles up to and including Model Year 2017.

Revision History

This Technical Service Bulletin has undergone several revisions to update its header and expand the applicable model years:

• Revision 10: Updated the header to include Model Year 2025.
• Revision 9 (July 20, 2023): Revised the header to include Model Year 2024.
• Revision 8 (May 6, 2022): Revised the header to include Model Year 2023.
