2020-2026 Audi AC Not Cooling TSB 2067716/2

Symptoms of AC Malfunction

Owners of 2020-2026 Audi vehicles, including the Audi e-tron, may notice that their air conditioning system is not cooling effectively or is not cooling at all. A common indicator of this issue is the AC button on the climate control panel flashing. These symptoms suggest a problem within the vehicle's refrigerant circuit, leading to the Audi e-tron AC not cooling issue.

Diagnosis of Refrigerant Leaks

When technicians investigate the Audi e-tron AC not cooling issue, they typically find that the refrigerant circuit is either very low on refrigerant or completely empty. A thorough refrigerant leak diagnosis will pinpoint the leak at a connection point that uses an o-ring seal. The root cause is often identified as a faulty o-ring seal, which then requires replacement.

Repair Procedure Summary

Technical Service Bulletin 87 24 79 2067716/2, which supersedes Technical Service Bulletin Group 87 number 22-30 dated August 2, 2022, outlines the procedure for addressing refrigerant leaks caused by faulty o-rings. This bulletin was revised on July 10, 2024, to add Model Year 2025 vehicles to its scope.

When replacing an o-ring seal anywhere in the refrigerant circuit to repair a leak, Audi requires specific documentation. This is crucial for tracking potential product quality issues, especially since many o-rings are used in various locations across the vehicle's refrigerant system. Technicians must ensure that the exact location of the replaced o-ring seal is precisely documented in the warranty claim notes within the SAGA system. Additionally, photographic or video evidence of the repaired refrigerant component connection must be uploaded to Doc-IT, clearly showing the location of the repair. This detailed documentation helps Audi monitor and improve the quality of these components, particularly for the Audi e-tron AC not cooling concern.

Important Warnings for Owners
