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

Audi has issued Technical Service Bulletin (TSB) 87 24 95 2041717/12, dated December 17, 2024, which outlines a critical procedure for any repair involving the replacement of an air conditioning (A/C) compressor. This bulletin supersedes Technical Service Bulletin Group 87 number 24-89, which was dated September 20, 2024. The TSB applies to all Audi vehicles from model years 2010 to 2025, though NHTSA data specifically links it to 2022-2026 models.

Why the GFF Test Plan is Mandatory

This TSB, identified as 87 24 95 2041717/12, emphasizes that any A/C compressor replacement, regardless of the initial failure reason, must be accompanied by an ODIS GFF cooling performance test plan. This plan generates a "Function Test Log" version of the A/C system's performance. It also requires documentation of the recovered refrigerant volume. This Audi A/C compressor GFF test plan requirement is mandatory without exception to ensure proper system function and provide a record for quality control and warranty purposes.

Finding the ODIS GFF Test Plan

Before replacing an A/C compressor, technicians must run the ODIS GFF test plan. The location of this test plan varies depending on the specific vehicle, its equipment level, and the ODIS version. Since the A/C cooling performance test is a 'function test', it is generally found by navigating to sub-headers such as 'functions', 'other functions', 'general function tests', or 'basic settings complete' within the diagnostic program.

Here are common navigation paths based on the vehicle's control module:

• 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".

• 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".
  • Alternatively, from Diagnostic capable system: Select "00C5 - Thermal Management Control Module -J1024-" >> "00C5 – Basic Settings Complete" >> "Basic Setting Selection" >> "System function test" >> "Interior cooling".

• 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".

• 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".

Performing the Test and Post-Replacement Steps

Once the function test has been added to the list of “Tests in current test plan,” technicians must select "Vehicle is not cooling" to proceed. The cooling system performance test plan will then guide them through the necessary prompts.

• Test Outcome: If the A/C performance test returns "No malfunctions", no further repairs are needed, indicating the system is operating properly. If a malfunction is detected, further diagnosis and repair are required.

• Documentation Requirements: If the compressor is found faulty by the Audi A/C compressor GFF test plan and subsequently replaced, specific documentation steps must be followed:

  • 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. A complete diagnostic log is not required; only the test plan section is needed.
  • Print the summary report detailing the amount of refrigerant and refrigerant oil recovered/discharged from the A/C service machine. Upload an image of this report to DocIt.

Important Warnings

This TSB is informational only and is not applicable to any Audi Warranty. The variation in test plan location does not 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, technicians must file an ODIS Feedback report.
