On-Board Diagnostics
Fig. 15 Location of
Data Link Connector
(OLC)
On-Board Diagnostics monitors the components of your emission
control system. Each mon itored component in your engine system
has been assigned a code. In case of a malfunction, the component
will be identified and the fault stored as a code in the control module
memory.
The MIL light may also illum inate if there is a leak i n the on-board fuel
vapor recovery system.
If the light illuminates after a refuelling, stop
the vehicle and make sure the fuel filler cap is properly closed
~page 285.
In order to make an accurate diagnosis, the stored data can only be
displayed using special d iagnostic equipment (generic scan too l 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 hood release~ fig. 15. Your authorized
Audi dealer or a qualified service station can inter­
pret the code and perform the necessary repair.•
Electronic speed limiter
Your vehicle may be factory equipp ed w ith tires that are rated for a
maximum speed of 130 mph (210 km/h) . This is less than the
maximum speed of your vehicle. To reduce the risk of sudden tire
failure and loss of control if the vehicle is operated at excessive
speeds, your vehicle a lso has an electronic speed limiter. The elec­
tronic speed limiter prevents your vehicle from going faster than the
tire speed rating . For more information ~
page 318.
If the eng ine control unit receives faulty vehicle road speed signals ,
the Malfunction Indicator Lamp (MIL) will illuminate. If this
occurs, contact the nearest a uthorized Aud i dealer for assistance.
& WARNING
Always observe the posted speed limits and adjust your speed to
suit prevailing road , traffic and weather conditions. Never drive
your vehicle faster than the maximum speed rating of the tires
i nstalled. •
Auto Check Control
Introduction
The Auto-Check control monitors the funct io n of certain vehicle
features and components . It simply makes sure these features and
components are working properly. The Auto-Check control works as
long as the ignition is on, as well as whenever the vehicle is driven.
If a component is malfunctioning or if the need for an urgent repair
has been detected, this w ill appear in the instrument cluster display . .,,_

again even though the engine oil level checks OK on the
dipstick,
do not continue driving and do not let the
engine run in idle.

dealer for assistance.
[ i) 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 without delay. Do not wait until the red oil pres­ sure warning ~ starts to flash before you respond to the low oil
level warning _ . By then, your engine may already have suffered
serious damage. •
