2021-2026 Audi AC Not Cooling TSB 2067716

Owners of certain 2021-2026 Audi vehicles may experience issues with their air conditioning system, including insufficient cooling or complete failure. This problem, often indicated by a flashing AC button, is addressed by Audi Technical Service Bulletin (TSB) 2067716.

This TSB specifically highlights O-ring leaks within the air conditioning system as a potential cause for the Audi AC not cooling symptom. It provides guidance to technicians on proper documentation during diagnosis and repair, particularly for warranty claims.

Symptoms

If your Audi AC not cooling, you might observe the following:

• The air conditioning system is not working at all.
• The air conditioning system is only working insufficiently.
• The vehicle interior is not cooled or is only cooled insufficiently.
• The AC button on the dashboard is flashing.

Diagnosis and Documentation Requirements

When addressing an Audi AC not cooling complaint, technicians are instructed to first reproduce the customer's reported issue. This ensures that the repair directly addresses the observed problem. Repairs should only proceed if all specific criteria, such as model type, chassis number, engine/motor, gearbox code, PR number, part number, and software version, precisely match the TSB's guidelines. Failure to meet these criteria may result in warranty claim rejection and potential charges for parts.

A key aspect of this TSB is the emphasis on detailed documentation during any O-ring replacement. Technicians must precisely record the location of the damaged O-ring, including the part number of the corresponding line and component where the O-ring was fitted. This information is crucial for further component analysis and for proper warranty processing.

Owner Action

If you are experiencing your Audi AC not cooling or observing a flashing AC button, it is recommended to schedule an appointment with an authorized Audi dealership. Describe the symptoms clearly to the service advisor to assist technicians in diagnosing the issue.

Since this is a Technical Service Bulletin, the repair for an O-ring leak in the air conditioning system may be covered under Audi's warranty, provided your vehicle meets the applicable warranty guidelines and the issue is properly documented by the dealership. Always confirm warranty coverage with your service center before any work begins.
