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

Audi has released Technical Service Bulletin (TSB) 2074919/3, a Pending Service Solution (PSS), concerning a specific climate control issue affecting 2024-2025 Audi A3, S3, and RS 3 models. This bulletin, with a release date of December 1, 2025, details a condition where the Audi A3 S3 RS3 air flow intensity does not increase as expected when the blower level is set higher than 4 in manual air conditioning mode.

This PSS serves to document the issue and inform technicians and owners about the manufacturer's ongoing efforts to resolve it. It is important for owners to understand the nature of this concern and the recommended actions.

Revision History of TSB 2074919/3

This Technical Service Bulletin has undergone several revisions to update information regarding the condition and solution:

• Revision 1 (August 29, 2024): Initial publication of the bulletin.
• Revision 2 (February 19, 2025): Revised information regarding the production solution implementation date and the service solution date.
• Revision 3 (Date not specified, pending): Further revisions to the condition description, including the addition of the model table, and updates to the service solution's estimated time of arrival (ETA).

Symptoms of Reduced Air Flow

Owners of affected 2024-2025 Audi A3, S3, and RS 3 vehicles may experience a specific issue with their climate control system. The primary complaint is that "the intensity of the air flow when using manual air conditioning does not change when the blower speed is greater than 4." This means that despite increasing the fan speed setting beyond level 4, the actual volume of air coming from the vents does not increase.

This issue specifically impacts the manual air conditioning function. Audi notes that the climate control system operates normally and the function is not impaired when using the "AUTO" function or "AC MAX" settings. Workshop findings confirm that this complaint can be consistently reproduced by technicians. This directly affects the Audi A3 S3 RS3 air flow intensity when manual control is desired.

Technical Background and Production Solution

Audi has identified the root cause of this air flow intensity problem as a software issue within the vehicle's climate control system. To address this, an optimized software solution is being developed.

This optimized software is scheduled to be implemented in series production vehicles starting in week 48 of 2024. This means that newly manufactured vehicles from that point onward should not exhibit this particular air flow intensity concern.

Important Warnings for Owners

Audi has provided specific instructions for dealers and important information for owners regarding this pending service solution:

• Do Not Replace Components: Owners should be aware that "Do not replace any components for this condition since this will not resolve the customer's concern." This highlights that the issue is software-related, and replacing hardware parts like the blower motor or control modules will not fix the problem and would be an unnecessary expense.
• No Immediate Repair or Notification: While Audi is actively reviewing this matter, there is no immediate repair available. Owners will be advised if any action is determined to be needed, with a result expected by the end of the second quarter of 2026. This implies that owners will not receive a proactive notification or recall letter at this time, and no repairs are currently necessary.

Recommended Owner Action

If you own a 2024-2025 Audi A3, S3, or RS 3 and experience the described Audi A3 S3 RS3 air flow intensity issue, where the fan speed does not increase past level 4 in manual AC mode, Audi recommends the following:

1. Contact Your Dealer: Explain the concern to your authorized Audi dealer. They will inform you that the matter is under review by Audi.
2. Create a PSS Record: The dealer is instructed to "Create a PSS record in the PSS application through the Pending Service Solutions (PSS) link in Audi Now; Service | AU-US > Pending Service Solutions (PSS)." This step is crucial as it formally documents your vehicle's concern with Audi, linking it to TSB 2074919/3. This record ensures your vehicle is noted for future solutions.
3. Await Further Advisement: A resolution is expected by the end of the second quarter of 2026. Until then, no repairs are necessary for this condition.

Warranty Information

According to TSB 2074919/3, this bulletin is "informational only and not applicable to any Audi Warranty." This means that any diagnostic work or potential future repairs related to this specific software issue may not be covered under the standard Audi warranty terms at this time, as it is a pending solution. However, since Audi is actively working on a resolution, it is anticipated that a future service action or recall, once developed, would cover the repair.
