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-
18
ponent will be identified and the fault stored as a
code in the contro l module memory.
The MIL light may also illumin ate if there is a
l
eak in the on-boa rd fuel vapor recovery system.
If the light illuminates after a refuelling, stop
the vehicle and make sure the fue l filler cap is
properly closed c:> page 233 .
In order to make an accurate diagnosis, the stor-
ed data can only be displayed using special di ag-
nostic equipment (generic scan tool for OBD).
In order to connect the special diagnostic equip-
ment, push the plug into the Data Link Connector
(DLC). Th e DLC is located to the right of the hood
release c:> fig. 4.
Your authorized Audi dealer or a qua li fied service
station can i nterpret the code and perform the
necessary repair.

Do not use the diagnostic connector for per-
sonal use. Incorrect usage can cause malfunc-
tions, which can increase the risk of a colli-
sion!
