Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Tire Pressure Monitoring System (TPMS) General Information
Follow the information in the Owner's Manual.
If the vehicle has a tire pressure monitoring system display, it will be documented on the vehicle data label or in ELSA in Vehicle-Specific Information under "Vehicle Data" by the PR number. For A5, refer to EXPLANATION OF PRODUCTION CONTROL NUMBERS (PR NUMBER), AUDI A5 - TIRE PRESSURE MONITORING SYSTEM/TIRE PRESSURE MONITORING SYSTEM DISPLAY , or for A4, refer to EXPLANATION OF PRODUCTION CONTROL NUMBERS (PR NUMBER), AUDI A4 - TIRE PRESSURE MONITORING SYSTEM/TIRE PRESSURE MONITORING SYSTEM DISPLAY .
The tire pressure monitoring system monitors the pressure of the four tires while driving.
Replace any tire pressure sensors for safety reasons.
Do not clean tire pressure sensors with steam blasting or strong compressed air.
For safety reasons, replace the tire pressure monitoring sensor and clean the rim after using tire sealant.
The tire pressure monitoring system consists of a control module, a central antenna integrated in the control module and one tire pressure sensor in each of the four wheels.
If wheel positions on the vehicle are changed, tires are changed, tire pressure sensor are replaced or pressures are changed, control module must be readapted.
When changing a tire with tire pressure sensors (summer/winter tires), check the tire pressure and adapt the sensor to the control module.
A fault stored in the Diagnostic Trouble Code (DTC) memory will be saved if:
There is a system malfunction.
When installing less than four wheels with tire pressure sensors.
When installing tires or incorrect tire pressure sensors. (If this is the case, the yellow warning lamp in the instrument cluster "system malfunction diagram" illuminates and cannot be deactivated by the system.)
The system has detected new sensors but the Multimedia System Control Head -E380- button was not been pressed to confirm the current tire pressures. (In this case, the system malfunction is erased by pressing the button.)

When to See a Mechanic
Stop DIY work and contact a certified mechanic immediately if any of the following apply:
- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
