2024-2025 Audi A3/S3/RS3 Blower Air Flow Issue TSB 2074919/1

Symptoms of the Audi A3 Blower Air Flow Issue

Owners of certain 2024-2025 Audi A3, S3, and RS 3 vehicles may notice a specific problem with their manual air conditioning system. The primary symptom is that the "Air flow intensity does not change when blower level is higher than 4". This means that even if you increase the blower speed setting beyond level 4, the actual air flow from the vents does not increase proportionally. This particular Audi A3 blower air flow issue is confined to the manual air conditioning mode and does not affect the system when operating in "AUTO" function or "AC MAX" mode.

Technical Background: Software Issue

Audi has confirmed that the underlying cause of this Audi A3 blower air flow problem is a software issue. This indicates that the vehicle's control unit responsible for managing the HVAC system's blower motor is not correctly interpreting or executing commands when the manual blower speed exceeds level 4. The complaint can be consistently reproduced by technicians, confirming its presence.

Important Owner Information

Audi has provided specific guidance regarding this condition. It is crucial for owners to understand that no immediate repairs are necessary at this point. Do not replace any components for this condition since this will not resolve the customer’s concern. This warning prevents unnecessary part replacements and associated costs, as the issue is software-related.

What to Expect at the Dealership

If you experience this Audi A3 blower air flow problem, your Audi dealership will document the complaint. Technicians are instructed to create a Pending Service Solutions (PSS) record in the PSS application via AccessAudi. This process helps Audi track the prevalence of the issue while they work on a permanent fix. No physical repair will be performed at this time, as the solution is still under development.

Solution Timeline

Audi anticipates that a software solution for this blower air flow issue will be available by the first quarter of 2025. This timeline is subject to change, but it provides owners with an expectation of when a fix might be implemented. Once the solution is released, the Technical Service Bulletin 2074919/1 will be updated with further instructions for technicians.
