On-Board Diagnostics
Fig. 5 Location o f Data Li nk Con necto r (OLC)
On-Board Diagnostics monitors the components
of your emission control system. Each monitored
component in your engine system has been as­
s igned a code. In case of a malfunction , the com­
ponent will be identified and the fault sto red 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 light illuminates after a refueling, stop the
vehicle and make sure the fuel f iller cap is prop­
erly closed (only vehicles with gasoline engine)
r::'.>page 153 .
In order to make an acc urat e diagnosis, the stor­
ed data can only be displayed using special diag­
nostic equipment (generic scan tool for 080).
In order to connect the special d iagnost ic equip­
ment, push the p lug into the Data Lin k Connector
(DLC). The DLC is located to the right of the hood
release ¢
fig. 5.
Your authorized Aud i dea ler or qualified work­
shop can interpret the code and perform the nec­
essary repair.
_& WARNING ~
Do not use the diagnostic connector for per-
sona l use. Incorrect usage can cause malfunc­
tions, which can increase the risk of a colli­
sion!
