This notice, dated February 23, 2026, informs Audi dealer personnel about the upcoming closure of this specific service action.

What is an Audi Service Action?

An Audi Service Action, unlike a safety recall, is typically a proactive measure taken by the manufacturer to address potential issues or improve vehicle performance and reliability. These actions often involve inspecting or updating components that may not pose an immediate safety risk but could lead to customer dissatisfaction or premature wear.

In the case of Service Action 19P9, the focus was on the "Engine Coolant Concentration." Proper engine coolant concentration is crucial for maintaining the engine's operating temperature, preventing freezing in cold climates, and protecting against corrosion. An incorrect concentration could lead to overheating, freezing, or damage to cooling system components over time. While the specific details of the original action are not provided in this closure notice, it would have involved checking and adjusting the coolant mixture as necessary.

Understanding the Closure Notice for Service Action 19P9

This document serves as a formal notification to Audi dealers that Service Action 19P9 is concluding. For owners, this means that the period during which dealers are authorized to perform this specific service action under warranty or a special program is coming to an end. The official closure date for the action is March 1, 2026.

Important Deadlines for Dealers

The notice specifies critical deadlines for dealers. All outstanding claims for work completed under Service Action 19P9 must be submitted through the SAGA system by March 31, 2026. After this date, Audi will no longer accept claims for this service action, and no further payments will be processed for related work. This ensures that dealers finalize all administrative tasks associated with the program.

What This Means for Owners

For owners of affected 2021 Audi A6, A7, S6, and S7 models, this closure notice indicates that if your vehicle has not yet had Service Action 19P9 performed, you should contact your authorized Audi dealer immediately. While the service action officially closes on March 1, 2026, the claims deadline for dealers extends slightly longer. It is important to ensure any necessary adjustments to your Audi A6 Engine Coolant Concentration are completed before the program fully concludes.

If you have concerns about your Audi A6 Engine Coolant Concentration or believe your vehicle might be affected by Service Action 19P9 and has not yet been serviced, it is recommended to check your vehicle's service history or contact an Audi dealership. They can confirm if your vehicle was part of this service action and if the required work has been completed.
