2025 Audi A5/Q5/S5 Tire Pressure Not Storing TSB 2079417/1

Owners of certain 2025 Audi A5, Q5, and S5 vehicles may encounter a problem where the tire pressure monitoring system fails to store or display tire pressures correctly. This issue, detailed in Technical Service Bulletin (TSB) 2079417/1, specifically affects vehicles equipped with the direct measuring tire pressure monitoring system (PR number 7K3).

Symptoms

Owners of affected vehicles may notice several symptoms related to the tire pressure monitoring system. The most common complaint is that the MMI display gets stuck at the "Storing values" stage when attempting to save tire pressures. Other observed issues include the tire pressures not being displayed on the MMI at all, or the display showing incorrect readings.

Specific complaints noted in the TSB include:

• "Tire pressure cannot be stored"
• "Tire pressure monitoring display" issues
• "Tire pressure monitoring system malfunction display"
• "Tire pressure loss information display" not activating
• "Wheel electronics adaptation mode" showing incorrect operation sequence or being unselectable
• General "functionality cannot be selected", "gives incorrect reading", "does not activate", or "no function" for tire pressure monitoring features
• "Display clarity design error"

Diagnosis and Trigger Conditions

This issue typically occurs in vehicles fitted with the direct measuring tire pressure monitoring system (PR number 7K3). The primary condition is that tire pressures are not displayed on the MMI, and the system gets stuck on the "Storing values" stage during the storage process. Workshop findings indicate that this complaint can be consistently reproduced and may even have been present during pre-delivery inspections.

The underlying technical background suggests that the display on the MMI is not being processed correctly, leading to the observed symptoms where the 2025 Audi A5 tire pressure cannot be stored.

Repair Procedure Summary

If your 2025 Audi A5 tire pressure cannot be stored and the display remains at the "Storing values" stage, the initial step involves pressing the "Back" button on the MMI. This action triggers the initialization of the tire pressure monitoring system, even if the display does not visually confirm it.

Following this, a test drive is required. The vehicle should be driven for approximately 10 minutes at a speed greater than 30 mph. During this drive, the tire pressures should eventually display correctly on the MMI.

If the display still does not work after performing the test drive, technicians should proceed to check the tire pressure monitoring system (module address 0065) and the sensors located in the tires. This diagnostic step requires the use of a specialized tool.

Required Tools or Parts

For further diagnosis if the initial steps do not resolve the issue, the following specialized tool is required:

• VAS 741099

Additionally, the tire pressure monitoring system control module, located at address 0065, will need to be inspected.
