On-Board Diagnostic
system (OBD)
Malfunction Indicator Lamp (MIL)
The Malfunction Indicator Lamp (MIL) Ill in
the instrument cluster is part of the On-Board
Diagnostic (OBD II) system.
The warning/indicator light illuminates when
the ignition is switched on and goes o ut after
the engine starts and the idle has stabilized.
This indicates that the MIL is working proper­
ly.
If the light does not go out after the engine
is started, or illuminates whi le you are driv­
ing, a ma lfunction may exist in the engine sys­
tem. If the light illuminates, the catalytic con­
verter could be damaged.
Continue driving
with reduced power (avoid­
ing sustained high speeds and/or rapid accel­
erations) 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 ¢
page 30, Electronic speed
limiter.
An improperly closed fuel filler cap may also
cause the MIL light to illuminate
¢page 162.
On-Board Diagnostics
Fig. 23 Location of Data Lin k Co nn ector (DLC)
On-Board D iagnostics monitors the compo­
nents of your emission control system . Each
monitored component in your engine system
has been ass igned a code. In case of a mal­
funct ion, the component 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 sys­
tem .
If the light illuminates after a refuelling,
stop the vehicle and make sure the fuel filler
cap is properly closed¢

from the vehicle.

150 Driving and en vironm ent
Avoid damaging the
vehicle
When you are driving on poor roads, or over
curbs, steep ramps, etc ., make certain that
low-lying parts such as spoilers and exhaust
system parts do not bottom out and get dam­
aged.
This is especially true for vehicles with low­
slung chassis (sports chassis) and fully loaded
vehicles .
Driving through water
on roads
Note the following to avoid vehicle damage
when driving through water, for example on
flooded roads:
- T he water must not be any highe r tha n the
bottom of the vehi cle body.
- Do no t drive faster than wa lking speed.
_& WARNING
After d riving through water, m ud, slush,
etc., the brakes may be slow to take effect
because o f wet brake ro tors and pads . Dry
the brakes fi rst by braking carefully to re­
store the full braking effect.
(]) Note
Vehicle components such as the engine,
transmiss ion, suspension or electrical sys ­
tem can be severely damaged by driving
through water.
- Check the depth o f the water before driv ­
ing through it.
- Do not stop the veh icle, dr ive in reverse
or switch the engine
off when driving
through water.
- Keep in mind that oncoming vehicles may c reate waves that raise the water
l evel and make it too deep for your vehi­
cle to drive through safely.
- Avoid driving thro ugh salt water because
it can ca use corrosion.
-
Catalytic converter
It is very important that your emission con­
trol system (catalytic converter) is function­
ing properly to ensure that your vehicle is run­
ning in an environmentally sound manner.
.. Always use lead-free gasoline¢ page 160,
Fuel supply .
.. Never run the tank down all the way to emp­
ty.
.. Never put too much moto r o il in yo ur eng ine
¢ page 169, Adding engine oil ~-
.. Never try to push- or tow-st art you r vehicle.
The catalytic co nverter is an efficient "clean­
u p" dev ice built into the exhaust system of
t h e vehi cle. The cata lytic conve rter bu rns
many of the pollutan ts in the exha ust gas be ­
f ore they are re leased into the atmosphere.
T he exclusive use of unleaded fuel is critically
impor tant for the life of the catalyt ic convert­
er and prope r funct ion ing of the engi ne.
A WARNING
- Do not park or operate the vehicle in
areas where the hot exha ust system may
come in contact with dry g rass, brush,
fue l spill or other material wh ich can
cause a fire.
- Do not app ly additiona l undercoating or
r u stproofing on or near the exhaust
manifold, exhaust pipes, catalytic con­
verter or heat sh ields. Dur ing driv ing, the
substance used fo r undercoating could
overheat and cause a fire.
(D Note
- Be aware that just one tank filling with
leaded fuel will already ser iously de-
grade the performance of the catalytic
converte r.
- Do not exceed the correct engi ne oil level
¢page 169.
-Do not drive until the fuel tank becomes
completely empty . The engine co uld mis-
fire. Unburned fuel could also get into ..,.
