2022-2023 Audi A/C Compressor Replacement TSB

Symptoms

Owners of 2022-2023 Audi vehicles may experience issues with their air conditioning system, leading to the need for an A/C compressor replacement. Common symptoms include a lack of cold air, unusual noises from the A/C system, or the A/C simply not functioning.

Diagnosis and Trigger Conditions

This Technical Service Bulletin (TSB) outlines a mandatory procedure for technicians when an Audi A/C compressor replacement is required. Before any A/C compressor is replaced, a specific diagnostic step must be performed: the ODIS GFF cooling performance test plan. This test plan is essential for accurately diagnosing the A/C system's performance and documenting the recovered refrigerant volume.

This requirement is mandatory and applies universally, regardless of the initial reason for the compressor's failure. The TSB specifies that the GFF test plan must be run without exception.

Repair Procedure Summary

When performing an Audi A/C compressor replacement, technicians must follow a detailed ODIS GFF cooling performance test plan. The navigation steps within the ODIS diagnostic program vary depending on the vehicle's specific equipment and model type:

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

  • Navigate to the Guided Functions tab, then select "08 – Front A/C display control head – E87" followed by "08 Heating/Air Conditioning Electronics, functions" and "08-Other Functions."
  • Alternatively, use the Test plan tab: navigate to "Body" > "Heating / Air Conditioning" > "01 – On Board Diagnostic (OBD) capable systems" > "08 Climatronic control module, functions J255" > "08-General function tests."

• For BEV (Battery Electric Vehicle) models with C5 - Thermal Management Control Module:

  • 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 (Plug-in Hybrid Electric Vehicle) models with C5 - Thermal Management Control Module:

  • 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 is added to the list of "Tests in current test plan," the technician should select "Vehicle is not cooling." If the A/C performance test returns "No malfunctions," no further repairs are needed for the A/C system. If a malfunction is detected and the compressor is found faulty and replaced, the final protocol of the Diagnostic Log must be uploaded to GFF Paperless, and the "Function Test" version of the diagnostic log must be attached to the replaced compressor for return to the WPRC.

Important Warnings

Owners and technicians should be aware of several critical points regarding this procedure:

• The ODIS GFF cooling performance test plan is mandatory without exception for any Audi A/C compressor replacement.
• If the A/C performance test returns the message "No malfunctions," then no repairs are needed for the A/C system, as it is operating properly.
• Variations in the test plan's location within ODIS, depending on the vehicle and equipment level, do not waive the requirement to run this test plan before an A/C compressor is replaced.
• If the test plan is missing or cannot be located in ODIS, technicians are instructed to file an ODIS Feedback report.

Warranty Information

Warranty claims for this procedure fall under specific categories:

• Claim Type 110: Applicable for vehicles up to 48 months or 50,000 miles.
• Claim Type G10: For Certified Pre-Owned (CPO) vehicles; owners should verify coverage.
• If the vehicle is outside of its warranty period, this Technical Service Bulletin serves as informational guidance only.

The Service Number associated with this procedure is 8734, and the Damage Code is 0016. Diagnostic time for the GFF test plan is 0150 0000 (maximum 100 TU). No allowance is provided for road tests before or after the service procedure.

Owner Action

If you own a 2022-2023 Audi and are experiencing issues with your air conditioning system that may require an A/C compressor replacement, it is important to take your vehicle to an authorized Audi service center. Ensure that the technicians are aware of and follow the mandatory ODIS GFF cooling performance test plan as outlined in TSB 2041717/8. This ensures proper diagnosis and repair of your vehicle's A/C system.
