2024-2025 Audi A3 / S3 / RS 3 Air Flow Intensity Issue

Symptoms

Owners of 2024-2025 Audi A3, S3, and RS 3 vehicles may notice that the air flow intensity from the air conditioning system does not change when the blower speed is manually set to a level greater than 4. This means that despite increasing the fan speed setting, the volume of air being delivered into the cabin remains the same, leading to insufficient cooling or heating. This specific symptom, related to the Audi A3 air flow intensity, is observed only when using the manual air conditioning function.

It is important to note that the air conditioning system's function is not impaired when operating in "AUTO" mode or when the "AC MAX" function is activated. In these modes, the system should operate as expected, delivering appropriate air flow.

Technical Background

Audi has identified the root cause of this air flow intensity issue as a software problem within the vehicle's air conditioning control system. This software anomaly specifically affects the logic that controls the blower motor's output when the system is in manual mode and the fan speed is requested above a certain threshold.

Important Owner Advisories

Audi Transaction Number 2074919/2 provides crucial guidance for both technicians and owners regarding this condition. It explicitly states that no repairs are necessary at this point, and technicians are advised: "Do not replace any components for this condition since this will not resolve the customer's concern." This means that attempting to replace parts like the blower motor or control modules will not fix the underlying software issue and would result in unnecessary costs and effort.

Furthermore, Audi is currently tracking this issue through its Pending Service Solutions (PSS) system. This indicates that while a fix is in development, there is no immediate service action available for existing vehicles. Owners will not receive a direct notification for a repair until a service solution is finalized.

Current Status and Future Solution

Audi has already implemented an optimized software solution in series production for new vehicles, starting in week 48 of 2024. This ensures that newly manufactured 2025 Audi A3, S3, and RS 3 models will not exhibit the Audi A3 air flow intensity problem.

For vehicles already on the road, a service solution is currently under development. Audi anticipates that this service solution will not be available before the third quarter of 2025. This timeline is subject to change. Until then, owners experiencing the issue should be aware that no repair is immediately available.

What Owners Should Do

If you own a 2024 or 2025 Audi A3, S3, or RS 3 and are experiencing the described Audi A3 air flow intensity issue where the air flow does not change when the blower level is set higher than 4 in manual air conditioning mode, you should visit an authorized Audi dealership. While no repair is currently available, the dealership can document your complaint by creating a PSS record in the Pending Service Solutions application. This record helps Audi track the prevalence of the issue and ensures that your vehicle is noted for a future software update when the service solution becomes available. Do not authorize any component replacements for this specific symptom, as they will not resolve the problem.

Revision History

This bulletin, Transaction Number 2074919/2, was initially published on August 29, 2024. A revision (Revision 2) was made to update information regarding the production solution implementation date and the expected service solution date.
