Warning light in the instrument cluster display-1-
If the _L warning light in the i nstrument clus ter display flashes, this
can mean one of two things: either the coo lant
temperature is too
high, or the coolant
level is too low ~ page 31 .
If the needle is well in the uppe r area of the gauge, the coo lant
temperature is too high.
Stop the vehicle, switch the engine off, and

could burn yourself . Let the engine cool off first so that you cannot
hear or see any steam or engine coolant .
0 Note
• Mounting add ition al lights o r accesso ries in fron t of the a ir inlets
reduces the cooling effect of the radiator . At high outside tempera­

On-Board Diagnostic system (OBD)
Malfunction Indicator Lamp (MIL)
The Malfunction Indicator Lamp (MIL) in the instrument cluster
=;,
page 12, fig. 7 is part of the On-Board Diagnostic (OBD II) system.
The warning/indicator light illuminates when the ignition is switched
on and goes out after the engine starts and the idle has stabilized.
This indicates that the MIL is working properly.
If the light does not go out after the engine is started, or illuminates
while you are driving, a malfunction may exist in the engine system.
If the light illuminates, the catalytic converter could be damaged.
Continue driving
with reduced power (avoiding sustained high
speeds and/or rapid accelerations) and have the condition corrected.
Contact your authorized Audi dealer .
If the light illuminates , the electronic speed limiter may also be
malfunctioning. For more information=;,

- 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.

• 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 2 72, "Engine compartment".

Engine oil pressure malfunction The red engine oil pressure warning symbol requires
immediate service or repair. Driving with a low oil pres­
sure indication is likely to cause severe engine damage.
If the 'l=:7: symbol on the display flashes, the engine oil pres­
sure is too low. A driver message appears as well to explain
the malfunction in more detail. The driver warning goes out

If the engine oil level is too low, add engine oil=> page 284.
Engine oil level correct
If the symbol 't=7: flashes even though the engine oil level is correct,
please seek professional assistance . Do not continue driving . Do not
leave the engine running
idle, either.
(I] Tips
• The engine oil pressure symbol~ 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 ... :lo requires oil refill or
workshop service without delay. Do not wait until the red oil pres­
sure warning ~ starts to flash before you respond to the low oil
level warning . By then, your engine may already have suffered
serious damage. •
