Brake system malfunction
BRAKE (USA models) /
(CD) (Canada models)
A malfunction in the brake system must be repaired as
soon as possible.
When BRAKE/ (CD) (Canada models) appears in the display
and flashes, this means there is a malfunction in the brake
system. In addition to the symbol, one of the following two
messages also appears in the display:
STOP VEHICLE AND CHECK BRAKE FLUID
ABS FAULT! SEE OWNER'S MANUAL
- Pull of the road and stop the vehicle.
- Check the brake fluid level=>
page 230.
USA models: if there is a malfunction in the ABS system, the i:i
warning/indicator light illuminates along with the BRAKE system
malfunction warning/indicator light=>&.
Canada models: if there is a malfunction in the ABS system, the
warning/indicator light illuminates together with the ID brake
system malfunction warning/indicator light=>& .
& WARNING
• Always observe the warnings in=> page 212, "Engine compart­
ment", before opening the engine hood and checking the brake
fluid.
• Driving with low brake fluid is a safety hazard! Stop the car and
get professional assistance .
• If the brake system warning/indicator light illuminates
together with the ABS warning/indicator light, then the ABS
system is malfunctioning. The rear wheels could quickly lock up
when you apply the brakes. This could lead to loss of control _and
your vehicle could slide! Drive carefully to the nearest authorized
Audi dealer and have the malfunction corrected. •
Engine cooling system malfunction _t_
A malfunction in the engine cooling system must be
repaired as soon as possible.
When the _t symbol in the display flashes, then either the
engine coolant
temperature is too high, or the coolant level
is too low. In addition to the symbol, the following message
also appears in the display:
SWITCH OFF ENGINE AND CHECK COOLANT LEVEL
-Pull off the road and stop the vehicle .
Turn off the engine.
Check coolant level =>
page 228.
Add coolant if necessary => page 228.
-Continue driving only after the engine coolant
warning/indicator light goes out.

-Contact your authorized Audi dealer for assistance if
necessary.
If the engine coolant level is correct, then the radiator fan may be
the cause of the malfunction.
If the generator warning/indicator light should also illuminate
=> page 19 , then the fan belt may be damaged.
& WARNING
• If your vehicle should break down for mechanical or other
reasons, park at a safe distance from moving traffic, turn off the
engine and turn on the hazard warning lights
=> page 75, "Emer­
gency flasher A".
• Never open the hood if you see or hear steam or coolant
escaping from the engine compartment -you risk being scalded.
Wait until you can no longer see or hear steam or coolant
escaping.
• The engine compartment of any vehicle is a dangerous area.
Before you perform any work in the engine compartment, turn of
the engine and allow it to cool. Follow the warning stickers
=> page 212, "Engine compartment".
0 Note
Do not continue driving if the _F_ symbol illuminates. There is a
malfunction in the engine cooling system -you could damage your
engine. •

Engine oil pressure malfunction 'l=;:f.
The red engine oil pressure warning symbol requires
immediate service or repair. Driving with a low-oil-pres­
sure indication is likely to result in serious damage to the
engine.
If the ~ symbol appears in the display and flashes, the oil
pressure is too low. In addition to the symbol, the following
message also appears in the display:
SWITCH OFF ENGINE AND CHECK OIL LEVEL
Immediate actions
- Pull off the road and stop the vehicle.
- Shut the engine down.
- Check the engine oil level with the dipstick=> page 224.
Dipstick reading checks too low
- Top off oil to the proper level
=> page 225.
- Make sure that the oil pressure warning symbol ~
appears no longer in the display before you start driving
again.
Dipstick reading checks OK
- If the ~ symbol starts flashing again even though the
engine oil level checks OK on the dipstick ,
do not start
driving again and do not let the engine run at idle .
Instead, contact your authorized Audi dealer for assis­
tance.

[ i] Tips
• The engine oil pressure symbol 9:::r. is not an indicator for a low
engine oil level. Do not rely on it. Instead, check the oil level in your
engine at regular intervals, preferably each time you refuel, and
always before going on a long trip.
• The yellow oil level warning indication · requires oil refill or
workshop service without delay. Do not wait until the red oil pres­
sure warning symbol
9:::r. starts to flash before you respond to the
low oil level warning . By then, your engine may already have
suffered serious damage. •

• the wire connection to the light bulb is defective.
Have the bulb replaced or the connection repaired by your autho ­
rized Audi Service department.
& WARNING
• 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! •

Fig. 30 Display:
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.
Controls and equip ­
ment
Driver inform ation 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. •
