2022-2026 Audi A/C Compressor Replacement TSB 2041717/11

Why This Matters

Audi Technical Service Bulletin (TSB) 87 24 89 2041717/11, also known as TSB 2041717, establishes a critical procedure for any Audi A/C compressor replacement. This bulletin makes it mandatory to perform an ODIS GFF cooling performance test plan before replacing an A/C compressor, regardless of the reason for its failure. This ensures a thorough diagnosis of the A/C system and proper documentation of the repair process.

Important Warnings

Audi emphasizes the mandatory nature of this procedure with a direct notice:

"As previously mentioned, the cooling performance test plan is in various locations in the navigation depending on the vehicle and equipment level. This variation in test plan location does not in any way waive the requirement for this test plan to be run before an air conditioning compressor is replaced. If the test plan is missing or cannot be found in ODIS, please file an ODIS Feedback."

This means that the test plan must be completed before any Audi A/C compressor replacement, even if it is difficult to locate within the ODIS system.

Diagnosis and Repair Procedure Summary

Before performing an Audi A/C compressor replacement, technicians must run the ODIS GFF test plan. This test helps evaluate the A/C system's cooling performance. The test plan is typically found under 'functions', 'other functions', or 'general function tests' within the ODIS diagnostic program.

Navigating ODIS for the GFF Test Plan:

• For vehicles with 08 - Heating and Air Conditioning Electronics: Navigate to the Guided Functions tab, select "08 – Front A/C display control head –E87-" >> "08 Heating/Air Conditioning Electronics, functions" >> "08-Other Functions." Alternatively, from the Test plan tab, 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: Navigate to "Diagnostic capable system" >> "00C5 - Thermal Management Control Module -J1024-" >> "00C5 - Thermal management control module, functions" >> "System function test" >> "Interior cooling."
• For PHEV vehicles with C5 - Thermal Management Control Module: Navigate to "Body" >> "Heating / Air Conditioning" >> "01 - On Board Diagnostic (OBD) capable systems" >> "00C5 - Thermal Management Control Module -J1024-" >> "00C5 – Thermal management control module, functions" >> "System function test" >> "Interior cooling."
• For vehicles with HVAC control in 09-Vehicle Electrical System Control Module: Navigate to "Body" >> "Electrical Equipment" >> "01-On Board Diagnostic (OBD) capable systems" >> "09-Vehicle Electrical System Control Module J519" >> "09-Electric Central Electric, functions" >> "09-Other functions, Air Conditioning test plan." Once the function test is added, select "Vehicle is not cooling."

Post-Test Actions:

• If the A/C performance test indicates "No malfunctions," no further repairs are necessary, as the system is functioning correctly.
• If a malfunction is detected, further diagnosis and repair are required. If the compressor is determined to be faulty and replaced, the following documentation steps are mandatory:
  • Upload a final protocol of the Diagnostic Log to GFF Paperless.
  • Print and attach the "Function Test" version of the diagnostic log to the replaced compressor for return to the WPRC (Warranty Parts Return Center).
  • Print the summary report detailing the amount of refrigerant and refrigerant oil recovered/discharged from the A/C service machine, and upload an image of this report to DocIt.
