On-Board Diagnostics monito rs the compo -
nents of your emission control system . Each
mon itored component in your engine system
has been assigned a code. In case of a mal-
f unction, the component will be identified
and the fault stored as a code in the control
module memory .
In order to make an accurate diagnosis, the
stored data can only be displayed using spe-
cial diagnostic equipment (gener ic scan tool
for OBD).
In order to connect the special diagnostic
equipment, push the plug into the Data Link
Connector (DLC). The DLC is located to the
right of the engine compartment lid release
c::,;, fig. 10 .
Your author ized Audi dealer or a qualified
service station can interpret the code and per-
form the necessary repair.

but t on @
c:> page 23, fig. 12.
You can te ll wh ich memory level is currently
active by t he number in the display c:> fig. 11.
The data from t he single -trip memory (memo -
ry level 1) is being displayed if a 1 appears in
the display. If a 2 is shown, then the data
from the total-trip memory is being displayed
(memory level 2).
Single -trip memory (Trip compute r 1)
The sing le-trip memory stores t he trip infor -
mation from the time the ignition is turned on
unt il it is turned off. If the t rip is cont inued
within 2 hours from the time the ignition was
turned off, the new data will be included in
the calculat ion of the current tr ip informa -
t ion. If the trip is interrupted fo r more than 2
hours the memo ry is reset automatically .
Total-trip memory (Trip computer 2)
Unlike the single-trip memory, the total-trip
memory is not reset automat ically . This per-
mits you to evaluate your driv ing data for the
entire per iod between ma nual resets.
Fuel range
The estimated cruising range in miles (km)
appears in t he display . The display changes in
increments of 6 m iles (10 km) .
