2010-2026 Audi A/C Compressor Test Plan TSB

Audi has issued Technical Service Bulletin (TSB) 87 24 95 2041717/12, which details a mandatory procedure for technicians when replacing an air conditioning (A/C) compressor in 2010-2026 Audi vehicles. This TSB supersedes previous bulletin 87 24-89 and emphasizes the importance of a specific diagnostic test.

This bulletin ensures that all A/C compressor replacements, regardless of the initial reason for failure, include a thorough system check. The required procedure is an ODIS GFF cooling performance test plan, which must be completed without exception.

When This TSB Applies

This TSB applies whenever a repair requires the replacement of the air conditioning compressor in your Audi vehicle. It is not about diagnosing a specific A/C compressor fault, but rather a mandatory step during the replacement process.

Diagnosis and Test Plan

Before replacing the A/C compressor, technicians must run the ODIS GFF test plan. This test plan is a 'function test' designed to evaluate the A/C system's cooling performance. The navigation path for this test varies depending on the vehicle's specific configuration and ODIS version.

For vehicles equipped with 08 - Heating and Air Conditioning Electronics, technicians will navigate through the Guided Functions tab of the diagnosis program. They will select "08 – Front A/C display control head –E87-" then "08 Heating/Air Conditioning Electronics," and finally "08-Other Functions." Alternatively, they can go to 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 and PHEV vehicles with C5 - Thermal Management Control Module (J1024), the path is "Diagnostic capable system >> 00C5 - Thermal Management Control Module -J1024- >> 00C5 - Thermal management control module, functions >> System function test >> Interior cooling." Another option is "Diagnostic capable system >> 00C5 - Thermal Management Control Module -J1024- >> 00C5 – Basic Settings Complete >> Basic Setting Selection >> System function test >> Interior cooling."

Vehicles with HVAC control in the 09-Vehicle Electrical System Control Module (J519) will follow the path: "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, technicians select "Vehicle is not cooling" to proceed with the cooling system performance test plan.

If the A/C performance test returns "No malfunctions", it indicates the system is operating properly, and no repairs are needed. If a malfunction is detected, further diagnosis and repair are required. If the Audi e-tron A/C compressor or any other Audi A/C compressor is found faulty and replaced, specific documentation is mandatory.

Repair Procedure Summary

When an A/C compressor is replaced following a malfunction identified by the ODIS GFF test plan, technicians must adhere to strict documentation requirements:

• Upload Diagnostic Log: A final protocol of the Diagnostic Log must be uploaded to GFF Paperless.
• Attach Function Test Log: The "Function Test" version of the diagnostic log must be printed and attached to the replaced compressor for return to the WPRC. It is not necessary to print the complete diagnostic log; only the test plan section is required.
• Upload Refrigerant Report: An image of the summary report showing the amount of refrigerant and refrigerant oil recovered/discharged from the A/C service machine must be uploaded to DocIt.

Important Warnings

It is crucial to understand that the ODIS GFF cooling performance test plan is mandatory for all A/C compressor replacements. The variation in test plan location within ODIS does not waive this requirement. If the test plan is missing or cannot be found in ODIS, technicians must file an ODIS Feedback report.

This TSB is informational only and does not apply to any Audi Warranty. Always check with your Parts Department and service manuals for the latest information regarding parts and service references (TSB 2041717).

Owner Action

If your 2010-2026 Audi vehicle, including an Audi e-tron A/C compressor, requires an A/C compressor replacement, ensure your service center is aware of this Technical Service Bulletin. This mandatory test plan helps confirm the repair's necessity and proper function of the new compressor. There is no direct action for owners beyond ensuring any A/C service is performed by a qualified technician following Audi's guidelines.
