(D 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

requires oil refill or workshop service with­
out delay. Do not wait until the red oil
pressure warning. starts to flash before
you respond to the low oil level warning
m. By then, your engine may already have
suffered serious damage.

Some functions and vehicle components are
scanned for their operati ng status when you
switch the ign ition on and whi le you a re driving.
Malfunctions or required service procedures are
s ignaled audib ly and ind icated by red and yellow
illuminated symbols and rem inders in the dis­
play.
A WARNING
-
- Never rely exclusively on the o utside tem­
perature display to determine if a road sur­
face is icy or not. Keep in mind that road sur­
faces, especially bridges and overpasses, could be ice covered and slippery even at an
outs ide temperature above 41 °F (+5 °C).
- Always remember, even i f the "snowflake"
symbo l (ice warning) does not appea r in the
display, black ice could be on the road.
- Always reduce your speed and drive with
specia l care in cold weather cond itions when
the chance of encountering icy road surfaces
increases.
(D Tips
If the vehicle is stationary, or if you are driv­
i ng at a very low speed, the temperature
shown in the disp lay m ight be slightly higher
than the act ual outs ide temperatu re. This is
caused by the heat being radiated from the
engine.

On Board Diagnostic
System (OBD)
Malfunction Indicator Lamp (MIL)
The Malfunction Indicator Lamp (MIL) ¢.ij in the
instrument cluster is part of the On-Board Diag­
nostic (OBD II) system.
The warning/indicator light illuminates when the
ignit ion is switched on and goes out after the en­
g ine starts and the idle has stabilized. Th is ind i­
cates that the MIL is working properly.
28
If the light does not go out after the engine is
started, or i lluminates while you are driving, a
malfunction may exist in the eng ine 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.
An improperly closed fuel filler cap may also
cause the MIL light to illuminate
c::;, page 185.
On-Board Diagnostics
Fig. 17 Locatio n of Data Link Co nnector (O LC)
On-Board Diagnostics monitors the components
of your emission control system. Each monitored component in your engine system has been as ­
signed a code. In case of a malfunction, the com­ ponent will be identified and the fault stored as a
code in the control module memory.
The MIL light may also illuminate if there is a
leak in the on-board fuel vapor recovery system.
If the l ight illuminates after a refueling, stop the
vehicle and make sure the fuel filler cap is prop­
erly closed
c::;, page 185.
In order to make an accurate diagnosis, the stor­
ed data can only be displayed using special diag­
nostic equipment (generic scan tool for OBD).
In order to connect the specia l diagnostic equip­
