- Fig. 1 Display: Indicator lamp with message
Applies to vehicles: with tyre pressure monitoring display
The tyre pressure monitoring display in the instrument cluster informs the driver if the tyre pressure is too low or a system malfunction has occurred.
The tyre pressure monitoring system makes use of the ABS sensors to compare the rolling circumference and the vibration of the wheels. If changes in the tyre pressure are detected on one or more wheels the driver is alerted by an indicator lamp 
or 
and a message in the instrument cluster display Fig. 1. If only one tyre is affected, the display will indicate its position.
or and a message in the instrument cluster display Fig. 1. If only one tyre is affected, the display will indicate its position.Monitoring of the tyre pressures is based on the tyre pressures you have stored. Each time you change a tyre, change the wheels round or change the tyre pressures on your vehicle (e.g. when switching from partial load to full load and vice-versa), you must store the new tyre pressures on the MMI Link. The tyre pressures recommended for your vehicle are given on the sticker attached to the driver's door pillar Link.
The rolling circumference and vibration can change and cause a tyre pressure warning if:
- The inflation pressure in one or more tyres is too low.
- The tyre has suffered structural damage.
- The wheels were changed or the tyre pressures were changed and the new tyre pressures were not stored Link.
Warning and indicator lamps
One or more of the tyres has suffered slight loss of pressure WARNING!. In addition, the indicator lamp in the instrument cluster will light up. Check and adjust the tyre pressures for all four wheels and store the new tyre pressures on the MMI. One or more of the tyres has suffered severe loss of pressure WARNING!. In addition, the indicator lamp in the instrument cluster will light up. Check and replace the tyre(s) or repair the wheel. Check and adjust the tyre pressures for all four wheels and store the new tyre pressures on the MMI.TPMS (Tyre Pressure Monitoring System) Tyre pressure ! System malfunction. If TPMS appears and the indicator lamp in the instrument cluster display flashes for approx. one minute and then lights up continuously after you have switched on the ignition or while you are driving, there is a fault in the system. Please contact the nearest qualified workshop as soon as possible.
in the instrument cluster display flashes for approx. one minute and then lights up continuously after you have switched on the ignition or while you are driving, there is a fault in the system. Please contact the nearest qualified workshop as soon as possible.- If the tyre pressure indicator lamp appears in the instrument cluster display, slow down immediately and avoid any severe braking or steering manoeuvres. As soon as you can do so safely, stop and check the tyres and the tyre pressures.
- It is the driver's responsibility to ensure that the tyre pressures are correct. For this reason you must check the tyre pressures regularly.
- Under certain conditions (e.g. driving at high speeds, on ice and snow or on poor road surfaces) the tyre pressure indicator lamp may not light up immediately.
- The use of run-flat tyres on your vehicle is NOT authorised! Unauthorised use can cause an accident or damage your vehicle.
Note
- If a malfunction occurs in the ESP/ABS system, the tyre pressure monitoring display will also be out of action.
- When driving with snow chains, a system malfunction can occur.
- The tyre pressure monitoring display on your Audi is specially matched to tyres with the marking "AO" or "RO". We recommend that you use these tyres.
