How to Fix an AUDI Tire Pressure Malfunction

If your Audi displays a “Tire Pressure Malfunction” warning, it usually means the Tire Pressure Monitoring System (TPMS) has detected incorrect pressure levels or lost communication with one or more sensors. Fortunately, this issue can often be resolved quickly with a few simple steps — without requiring a visit to the dealership. Follow this comprehensive guide to safely fix and reset the system so your Audi drives smoothly again.

1. Check Tire Pressure on All Four Tires
Start by inspecting the pressure of each tire using a reliable digital gauge. Audi’s recommended tire pressure varies by model, but you can find the correct specification on the driver’s door frame or in your owner’s manual. Make sure all four tires — including the spare if equipped with a sensor — are inflated to the proper PSI. Underinflated or overinflated tires can both trigger the malfunction light. Adjust the pressure using an air compressor until all tires are within the recommended range. After this adjustment, drive the car for a few minutes to see if the warning disappears.

2. Perform a Manual TPMS Reset
Audi Tire Pressure Malfunction: If the message remains, you may need to reset the TPMS manually. Audi models allow this via the infotainment system or the MMI (Multi Media Interface). Here’s how:

• Turn on the ignition without starting the engine.

• Navigate to the “Car” or “Vehicle” menu.

• Select “Service & Checks” → “Tire Pressure Monitoring” → “Store tire pressures.”

• Confirm that you’ve set the correct pressure, then choose “Store.”
  The system will memorize the current pressures as the baseline. After driving a few kilometers, the malfunction warning should disappear if everything is functioning normally.

3. Reset Through the Steering Wheel Controls (Older Models)
Some older Audi models, such as early A4 or Q5 versions, use steering wheel buttons to reset the TPMS. Turn on the ignition, press the “CAR” button, go to “Tire Pressure Monitoring,” and select “Confirm Tire Pressures.” This process tells the car that the current pressures are correct. If the warning light remains, turn off the ignition, wait 30 seconds, and restart the car to reinitialize the system.

4. Inspect for Tire Leaks or Punctures
If the light reappears after resetting, you might have a slow air leak or a puncture. Use a soapy water solution and spray it around the tire tread and valve stem. Bubbling indicates escaping air. Small punctures can be temporarily fixed using a tire sealant or plug kit, but permanent repair at a tire shop is recommended for safety.

5. Check the TPMS Sensors
Each wheel contains a pressure sensor inside the valve stem or attached to the rim. These sensors communicate wirelessly with the vehicle’s control unit. You can identify faulty sensors using a TPMS diagnostic tool or at any tire service center. Replacing a bad sensor and reprogramming it usually clears the issue.

6. Inspect the Spare Tire (if applicable)
Some Audi SUVs, like the Q5 or Q7, have TPMS sensors in the spare tire as well. Check and inflate the spare to its correct PSI, and ensure its sensor is functioning.

7. Drive to Recalibrate the System
After correcting pressures and resetting the TPMS, take your Audi for a short drive — ideally at speeds above 25 mph (40 km/h) for 10–15 minutes. This helps the system read and store the new pressure data. If everything is working properly, the dashboard warning should disappear automatically.

8. Use Diagnostic Tools if the Warning Persists
If the malfunction light stays on, connect an OBD-II diagnostic tool to your Audi’s port (located under the dashboard). Check for fault codes related to the TPMS or wheel sensors. Common error codes like “C1114” or “C1116” indicate sensor communication loss. Clearing these codes after resolving the physical issue (like a bad sensor or incorrect pressure) will fully reset the warning system.

9. Software Update or System Calibration at a Service Center
In rare cases, a professional service center may need to update your vehicle software or recalibrate the TPMS using factory-level diagnostic equipment.

10. Preventing Future TPMS Malfunctions
To avoid seeing this warning again, check tire pressure at least once a month and before long drives. Always reset the TPMS after adjusting tire pressures or rotating tires. When changing wheels or installing aftermarket rims, ensure the sensors are properly installed and programmed. Regular maintenance keeps your Audi’s tire monitoring system accurate and helps extend tire life.

Conclusion
Most “Tire Pressure Malfunction” issues can be resolved with basic maintenance — checking tire pressure, resetting the system, and inspecting sensors. By following these steps, you can restore your Audi’s tire monitoring system and enjoy safe, confident driving every day.
