2024-2025 Audi A3, S3, RS 3 Air Flow Intensity TSB

Owners of certain 2024-2025 Audi A3, S3, and RS 3 models may notice that the air flow intensity from their manual air conditioning system does not increase when the blower speed is set higher than level 4. This condition, documented in Audi Technical Service Bulletin (TSB) 2074919/1, indicates a software-related problem. It's important to note that this issue does not affect the system when using the "AUTO" function or "AC MAX" settings.

Symptoms

If you own a 2024 or 2025 Audi A3, S3, or RS 3, you might experience the following:

• The intensity of the air flow does not change when using manual air conditioning, even when the blower speed is set to a level greater than 4.
• Despite increasing the blower setting, the perceived air output remains constant.

This specific problem, where the Audi A3 air flow intensity is affected, has been reproduced by workshop technicians, confirming the customer complaint.

Technical Background

Audi has identified the root cause of this air flow intensity issue as a software problem within the vehicle's climate control system. This means the hardware components of the air conditioning system are not at fault.

Important Warnings for Owners

Audi TSB 2074919/1 provides critical guidance regarding this issue:

• Do not replace components: Dealers are instructed "Do not replace any components for this condition since this will not resolve the customer's concern." Attempting to replace parts like the blower motor or control unit will not fix the underlying software problem and could result in unnecessary costs.
• Informational TSB only: This TSB is "informational only and not applicable to any Audi Warranty." This means that while Audi acknowledges the issue, the bulletin itself does not authorize warranty claims for this specific condition at this time. Owners should be aware that no formal recall or free repair program has been announced in conjunction with this TSB.
• Model applicability: The bulletin text states, "This bulletin applies to MY24 – 25 A3 vehicles only." However, the National Highway Traffic Safety Administration (NHTSA) has linked TSB 2074919/1 to Audi S3 and RS 3 models for the 2024-2025 model years as well. Owners of S3 and RS 3 vehicles experiencing this symptom should also consult their dealer.

Repair Procedure Summary

Currently, there is no immediate repair available for the Audi A3 air flow intensity problem. Audi expects a software solution to be available by the first quarter of 2025. Until then, the primary action for dealerships is to document the customer's complaint.

When a customer reports this issue, technicians are advised to:

1. Explain to the customer that a solution is anticipated by the first quarter of 2025 (though this timeline is subject to change).
2. Reiterate that no repairs are necessary at this point, and no components should be replaced.
3. Create a Pending Service Solutions (PSS) record in the PSS application via the "Pending Service Solutions (PSS)" link in AccessAudi. This step ensures that Audi tracks the prevalence of the issue and that affected vehicles are noted for future updates.

Owner Action

If you are experiencing the described air flow intensity issue in your 2024-2025 Audi A3, S3, or RS 3, here's what you should do:

• Contact your dealer: Inform your authorized Audi dealer about the problem. They should be aware of TSB 2074919/1 and can create a PSS record for your vehicle. This helps Audi monitor the issue and ensures you are in the system for when a fix becomes available.
• Do not seek unauthorized repairs: As advised by Audi, replacing components will not resolve this software-related problem.
• Monitor for updates: Keep an eye out for further communications from Audi or your dealership regarding the availability of the software update in early 2025. Since this is an informational TSB, direct owner notification may not occur, so proactive inquiry is recommended.
