TPMS Reset: Audi S4 2002-2009 Tire Pressure Monitoring System Sensor Relearn
Easy to follow tutorial on how to reset the TPMS Service Maintenance indicator message light on Audi S4 from the year 2002, 2003, 2004, 2005, 2006, 2007, 2008. 2009.
No special tools are required to perform this relearned procedure.
Audi A3 Sensor Relearn Procedure:
- Inflate all tires to pressure listed on the tire placard.
- Turn the ignition ON.
- Hold down the RESET button (B) (on the end of the wiper lever) until DISPLAY TIRE is displayed.
- Press the button, on the end of the wiper lever (A), to select SET.
- Press the RESET button (B).
- Press the button on the end of the wiper lever (A) to select TIRE PRESSURE.
- Press the RESET button.(B)
- Press the button on the end of the wiper lever (A) to select WHEEL CHANGE (select STORE PRESSURES if resetting air pressure).
- Press the RESET button (B). Relearn can take 20 minutes to complete.
- Drive the vehicle for at least 10 minutes at a speed of 15 MPH, or more. All sensor IDs will be memorized automatically.
Tire pressure monitoring system
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 underinflated. The TPMS only provides a low tire pressure warning and does not reinflate your tires.
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 underinflated 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.
TPMS malfunction indicator
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 starts up 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 prevents 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.
The tire pressure monitoring system monitors the air pressure in all four road wheels while the vehicle is moving.
As soon as the tire pressure monitoring system senses a significant loss of air pressure in one or several tires, text messages and yellow symbols appear in the instrument cluster display to alert the driver. The warning light in the instrument cluster comes on when the tire is significantly underinflated.
The warning light C also illuminates in the case of a system malfunction.
Be aware that tire pressure is also dependent on the temperature of the tire. For every 18 °F (10 °C) increase in tire temperature, tire pressure increases by about 1.5 psi (0.1 bar). The tire warms up while the vehicle is moving and tire pressure rises. So you should adjust the tire.
Pressure only when they are cold when the temperature of the tires is roughly the same as the ambient air temperature. In order to keep the tire pressure monitoring system properly calibrated, tire pressure on all four tires should be checked at regular intervals, adjusted if necessary, and saved in the proper setting (recommended pressure). The tire pressure is shown either on the driver’s side B-pillar or on the inside of the fuel filler flap.
- 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.
- Each tire, including the spare, 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.) •
