Tyre pressure: fault. See owner's manual
Applies to: vehicles with tyre pressure loss indicator
If appears and the indicator lamp in the
instrument cluster display flashes for approx.
one minute and then remains lit after you have
switched on the ignition or while you are driving,
there is a fault in the system. Try to store the cor-
rect tyre pressures ðpage 343. In some cases
the indicator lamp may not go out until you have
driven the vehicle for a few minutes after storing
the pressures. If the indicator lamp does not go
out or if it comes on again after a short time,
drive to a qualified workshop without delay and
have the fault rectified.
The tyre pressure loss indicator in the instrument
cluster informs the driver if the tyre pressure is
too low or a system malfunction has occurred.
The tyre pressure loss indicator makes use of the
ABS sensors to compare the rolling circumfer-
ence and the vibration of the tyres. If changes in
the inflation pressure are detected on one or
more tyres, the driver is alerted by an indicator
lamp and a message in the instrument cluster
display. If only one tyre is affected, the display
will indicate its position.
WARNING
Each time you change a tyre, change the wheels
round or change the tyre pressures on your vehi-
cle (e.g. when switching from partial load to full
load and vice-versa), you must store the new tyre
pressures ðpage 343. Monitoring of the tyre
pressures is based on the tyre pressures you have
stored. The inflation pressures recommended for
your vehicle are given on the tyre pressure sticker
ðpage 338, Fig. 208.
– If the tyre pressure loss indicator appears on
the display, slow down immediately and
avoid any severe braking or steering ma-
noeuvres. As soon as you can do so safely,
stop and check the tyres and the tyre pres-
sures.
– It is the driver's responsibility to ensure that
the tyre pressures are correct. For this rea-
son you must check the tyre pressures regu-
larly.
The rolling circumference and vibration can
change and cause a tyre pressure warning if:
– Under certain conditions (e.g. driving at high
speeds, on ice and snow or on poor road sur-
faces) the tyre pressure loss indicator may
not appear immediately.
– The inflation pressure in one or more tyres is
too low.
– The tyres have suffered structural damage.
– The wheels were changed or the tyre pressures
were changed and the new tyre pressures were
not stored ðpage 343.
Note
– If a malfunction occurs in the ESC system,
the tyre pressure loss indicator may also be
out of action.
– Only some of the worn tyres have been re-
placed.
– When driving with snow chains, a system
malfunction may occur.
Indicator lamps
If the indicator lamp lights up, there is a loss
of pressure on one or more tyres ð . Check the
tyre(s) and change them if necessary. Check and
adjust the inflation pressures of all four tyres
again and store the new tyre pressures
ðpage 343.
– The tyre pressure loss indicator on your Audi
is specially matched to “Audi Genuine Tyres”
ðpage 336. Audi recommends that you use
these tyres.
If the indicator lamp flashes and an acoustic
signal is issued although you have not yet stored
