2017 AUDI A7 sensor

Wheels
As an added safety feature, your vehicle has been
equipped with a tire pressure mon itor ing system
(TPMS) that illuminates a low tire pressure tell­
tale when one or more of your tires is significant­
ly 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 signifi­
cantly under-inflated tire causes the tire to over­
heat and can lead to tire failure. Under-inflation
also reduces fuel efficiency and ti re tread life,
and may affect the vehicle's handling and stop­
ping ability.
Please note that the TPMS is not a substitute for
proper tire maintenance, and it is the driver's re­
sponsibility to maintain correct tire pressure,
even if under- inflation has not reached the level
to trigger illumination of the TPMS low tire pres­
sure telltale.
Your vehicle has also been equipped with a TPMS
malfunction indicator to indicate when the sys­
tem is not operating properly. The TPMS mal­
function indicator is combined with the low tire
pressure telltale . When the system detects a
malfunction, the telltale will flash for approxi ­
mately one m inute and then remain cont inuously
illuminated . This sequence will continue upon
subsequent vehicle start-ups as long as the mal­
function exists .
When the malfunct ion 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.

Tire pressure monitoring system
Applies to: vehicles with Tire Pressure Monitoring System in­
dicator
The tire pressure indicator in the instrument
cluster informs you if the tire pressure is too low
or if there is a system malfunction.
Fig. 194 Instrumen t cl uster : indicator l ig ht with me ssage
Using the ABS sensors, the tire pressure monitor­
ing system compares the tire tread circumfer­
ence and vibration characteristics of the individu­
al tires. If the pressure changes in one or more
tires, this is indicated in the instrument cluster
display with an indicator light
Rt] and a message.
If only one tire is affected, the location of that
tire will be indicated.
The tire pressures must be stored in the Infotain­
ment system again each time the pressures
change (switching between partial and full load
pressure) or after changing or replacing a tire on
your vehicle
¢ page 231. The tire pressure mon i­
toring system only monitors the tire pressure you have stored . Refer to the tire pressure label for
the recommended tire pressure for your vehicle
¢page 221, fig. 193.
Tire tread circumference and vibrat ion character­
istics can change and cause a tire pressure warn­
ing if :
- the tire pressure in one or more tires is too low.
- the tire has structural damage.
- the tire was replaced or the tire pressure was
changed and it was not stored¢
page 231 .
-the spare tire* is installed.

malfunction, the telltale will flash for approxi­ mately one minute and then remain cont inuously
illum inated. This sequence will continue upon
subsequent vehicle start-ups as long as the mal­
function exists.
When the malfunct ion indicator is illuminated,
the system may not be able to detect or signal
low tire pressure as intended. TPMS ma lfunctions
may occur for a variety of reasons, including the
installation of replacement or alternate tires or

Description
A pp lies to: ve hicles w ith tire p ressure monitoring system
The tire pressure monitoring system monitors
the pressure in the four tires when driving.
The system uses sensors that measure the tem ­
perature and pressure in the tires . The data is
sent from these sensors to the contro l module by
radio frequency.
The Tire Pressure Monitoring System shows the current pressures and temperatures of the tir es
in the Infota inment system
c:> page 232. It also
compares the current t ire pressures with the
stored tire pressu res and gives a warning in the
d river information system if the tire pressure is
different from what is stored
r:';> page 233.
232
The system does not detect if the stored tire
pressures match the recommended tire pres­
sures. You must store the tire pressures again
c:> page 233:
-every time the tire pressures change, for exam ­
ple when the load in the vehicle changes,
- after replacing a tire, or
- if wheels with new whee l sensors are used.
_&. WARNING
- The tire pressure monitoring system assists
the driver in monitoring tire pressures. The
driver is responsib le for having the tires in­
flated to the correct pressure.
- Do not change the tire pressure when the
temperature of the tire is high. This could
result in serious damage to the tire and
even cause the tire to burst, increasing the
risk of an accident.
-A tire with low pressure flexes more. This heats the tire up too much. This could cause
the tread to separate and even cause the
tire to burst, increasing the risk of an acc i­
dent.
- The tire pressure monitoring system does
not warn about damage or defects in the
tire construct ion that could cause the tire to
burst, for examp le. Inspect your tires reg u­
larly.
(D Tips
- If tires are replaced, the sensors/valves do
not need to be removed or replaced. Just re­
placed the va lve stem and, if necessary, the
valve and the wheel electronics.
If you have
questions, see your authorized Audi dealer
or authorized Audi Service Facility.
- An incorrect display or a malfunction in the
tire pressure monitoring system can occur
after using the tire mobility kit. Have the
sensors rep laced by an authorized Audi
dealer or author ized Audi Service Facility.

Malfunctions
Appl ies to : vehicles wi th tire pressure mo nito rin g system
If the Tire Pressure Monitoring System is not
avai lable, the
mm indicator light appears in the
driver information system. The
Rt] indicator light
also blinks for approximately one minutes each
time the ignition is switched on. The tire pressure
monitoring system cannot be selected in the In­
fotainment system. The following are examples
of situations that could cause a malfunction:
- If the message appears at the end of the adap­
tation phase, the system cannot detect the
wheels installed on the vehicle. This may result
from one or more wheels being installed with­ out wheel sensors or with incompatible wheel
sensors.
- A wheel sensor or another component has
failed.
- Using snow chains can affect the function of
the system because of the shield ing effect of
the cha ins.
- The tire pressure monitoring system is not
available due to a malfunction .
- Transmitters with the same frequency, such as
headphones or remote-controlled devices, may
cause a temporary system malfunction due to
the strong electromagnetic field.
The
mm indicator light turns off once the Tire
Pressure Monitoring System is available again.
If
you cannot correct the malfunction and the mm
234
indicator light stays on, drive immediately to an
authorized Audi dealer or authorized Audi Service Facility to have the malfunction repaired.
