2016 AUDI S8 fuel cap release

On-Board Diagnostics monitors the components
of your emission control system. Each monitored
component in your eng ine system has been as­
signed a code . In case of a malfunction, the com­
ponent 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 system.
If the light illuminates after a refueling, stop the
vehicle and make sure the fuel filler cap is prop ­
erly closed
¢ page 214.
In order to make an accurate diagnosis, the stor­
ed data can only be displayed using special diag­
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) . The DLC is located to the right of the hood
release
c> fig . 17.
Your author ized Audi dealer or a qualified service
station can interpret the code and perform the necessary repair.
A WARNING
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!
Electronic speed limiter
Your veh icle may be factory equipped with t ires
that are rated for a maximum speed of 130 mph
(2 10 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 operat­
ed at excessive speeds, your vehicle also has an
electronic speed limiter. The electronic speed limiter prevents your vehicle from going faster
than the tir e speed rating . For more information
¢page 243 .
If the engine control unit receives faulty vehicle
road speed signals, the Malfunction Indicator
L amp
(Mil) Ill will illuminate . If this occurs,

- Fuel is highly f lammable and can cause se­
vere burns and other injur ies.

into the fuel filler neck could cause fuel to
spray out of filler neck or to overflow . Fuel
spray and overflowing fue l can cause a fire .
