Defective light bulb warning
The defective light bulb warning tells you when a vehicle
light bulb has become defective.
If a defective bulb has been detected by the system or a light bulb
burns out, the symbol with a message appears in the display to
tell you which bulb is burnt out and where it is located. For example:
REAR LEFT TURN SIGNAL
After 5 seconds, the message disappears. If you want to recall the
message into the display, press the CHECK button.
There are three reasons why the defective bulb message would appear in the display:
• the light bulb has burnt out=> page 277.
• the fuse is "blown" => page 273, "Replacing a fuse".
• the wire connection to the light bulb is defective.
Have the bulb replaced or the connection repaired by your autho ­
rized Audi Service department.

• Light bulbs are pressurized and could explode while they are
being changed causing serious personal injury.
• Work with due care when handling the high-voltage section of
gas discharge (xenon) lamps*. Failing to do so could result in death
or serious injury! •

System malfunction
If the t warning light in the instrument cluster flashes for approxi ­
mately one minute and then remains continuously illuminated and
additionally the
r fin'-=> fig. 30 symbo l appears in the display, the
tire pressure monitoring system is not available. This can have
various causes .
• If the message appears at the end of the learning process, the
system cannot recognize the wheels installed on the vehicle. This
can be because one or more wheels without a whee l sensor were
installed.
• A wheel sensor or other component may have failed .
• During initia lization the system has detected more than 4 wheels
on the vehicle, for example whi le driving next to another car with a
tire pressure monitoring system.

• A wheel change was made but the button => page 44, fig. 29 was
not pressed .
• Audi replacement parts were not used.
• If snow chains are being used, system function can be compro­
mised due to the shielding properties of the chains.
• The tire pressure monitoring system may not be available
because of a radio malfunction.
• Transmitters with the same frequency, such as radio head ­
phones in the vehic le or radio equipment, can cause a temporary
disruption of the system through excessive e lectromagnetic fields.
• Eliminate the interference if possible/if you can and then
proceed as follows: Turn off the engine for 20 minutes . Then drive
another 10 min. If the warning light comes on again, you should
contact your authorized Audi dealer immediately to have the
problem corrected.
• Do not use commercially available tire sealants. Otherwise, the
e lectrica l components of the tire pressure monitoring system will
no longer work properly and the sensor for the tire pressure moni­
toring system will have to be replaced by a qualified workshop. •
