Audi Q3: Tire pressure monitoring system

General notes

Each tire, including the spare (if provided), should be checked monthly when cold and inflated to the inflation pressure recommended by the vehicle manufacturer on the vehicle placard or tire inflation pressure label. (If your vehicle has tires of a different size than the size indicated on the vehicle placard or tire inflation pressure label, you should determine the proper tire inflation pressure for those tires).

As an added safety feature, your vehicle has been equipped with a tire pressure monitoring system (TPMS) that illuminates a low tire pressure telltale when one or more of your tires is significantly under-inflated. Accordingly, when the low tire pressure telltale illuminates, you should stop and check your tires as soon as possible, and inflate them to the proper pressure. Driving on a significantly under-inflated tire causes the tire to overheat and can lead to tire failure. Under-inflation also reduces fuel efficiency and tire tread life, and may affect the vehicle's handling and stopping ability.

Please note that the TPMS is not a substitute for proper tire maintenance, and it is the driver's responsibility to maintain correct tire pressure, even if under-inflation has not reached the level to trigger illumination of the TPMS low tire pressure telltale.

Your vehicle has also been equipped with a TPMS malfunction indicator to indicate when the system is not operating properly. The TPMS malfunction indicator is combined with the low tire pressure telltale. When the system detects a malfunction, the telltale will flash for approximately one minute and then remain continuously illuminated. This sequence will continue upon subsequent vehicle start-ups as long as the malfunction exists.

When the malfunction indicator is illuminated, the system may not be able to detect or signal low tire pressure as intended. TPMS malfunctions may occur for a variety of reasons, including the installation of replacement or alternate tires or wheels on the vehicle that prevent the TPMS from functioning properly. Always check the TPMS malfunction telltale after replacing one or more tires or wheels on your vehicle to ensure that the replacement or alternate tires and wheels allow the TPMS to continue to function properly.

If the tire pressure monitoring indicator appears

The tire pressure indicator in the instrument cluster informs you if the tire pressure is too low or if there is a system malfunction.

Using the ABS sensors, the tire pressure monitoring system compares the tire tread circumference and vibration characteristics of the individual tires. If the pressure changes in one or more tires, this is indicated in the instrument cluster display with an indicator light and a message.

If only one tire is affected, the location of that tire will be indicated.

The tire pressures must be stored again each time you change the pressures (switching between partial and full load pressure) or after changing or replacing a tire on your vehicle. The tire pressure monitoring system only monitors the tire pressure you have stored.

Refer to the tire pressure label for the recommended tire pressure for your vehicle fig. 157.

Tire tread circumference and vibration characteristics can change and cause a tire pressure warning if:

  • The tire pressure in one or more tires is too low
  • The tires have structural damage
  • The tire was replaced or the tire pressure was changed and it was not stored
  • Tires that are only partially used are replaced with new tires

Indicator lights

If the indicator light turns on, there is a loss of pressure in at least one tire. Check the tires and replace if necessary. Check and correct the pressures of all four tires and store the pressure again.

Tire pressure: malfunction! See owner's manual

If appears after switching the ignition on or while driving and the indicator light in the instrument cluster blinks for approximately one minute and then stays on, there is system malfunction.

Try to store the correct tire pressures. In some cases, you must drive for several minutes after storing the pressures until the indicator light turns off. If the indicator light does turn off or turns on again after a short period of time, drive to an authorized Audi dealer or authorized Audi Service Facility immediately to have the malfunction corrected.


  • If the tire pressure indicator appears in the display, reduce your speed immediately and avoid any hard steering or braking maneuvers.

    Stop as soon as possible and check the tires and their pressure.

  • The driver is responsible for maintaining the correct tire pressure. You must check the tire pressure regularly.
  • Under certain conditions (such as a sporty driving style, winter conditions, or unpaved roads), the tire pressure monitoring system indicator may be delayed.


  • The tire pressure monitoring system can also stop working when there is an ESC malfunction.
  • Using snow chains may result in a system malfunction.
  • The tire pressure monitoring system in your Audi was calibrated with "Audi Original Tires". Audi recommends using these tires.

Storing tire pressures

If the tire pressure changes or a tire is replaced, it must be confirmed in the system.

  • Before storing the tire pressures, make sure the tire pressures in all four tires meet the specified values and are adapted to the load.
  • Switch the ignition on.
  • Applies to MMI: Select on the home screen: VEHICLE > Settings & Service > Tire pressure monitoring > Store tire pressure > Yes, store now.


Do not store the tire pressures if snow chains are installed.
