On-Board Diagnostic system (OBD)
Malfunction Indicator Lamp (MIL)
The Malfunction Indicator Lamp (MIL) • in the instrument cluster
::::>
page 14, fig. 7 is part of the On-Board Diagnostic (OBD II) system.
Th e warn ing/indicator light illuminates when the ignition is switched
on and goes out after the engine starts and the idle has stabilized.
Thi s ind icates that the MIL is working properly.
If
the light does not go out after the engine is started, or illuminates
while you are driving , a ma lfunction may exist in the engine system.
If the light illuminates, the catalytic converter could be damaged.
Continue driving
with reduced power (avoiding sustained high
speeds and/or rapid accelerat ions) and have the condition corrected .
Contact your authorized Audi dealer .
If the light i lluminates, the electronic speed limiter may also be
malfunctioning. For more information::::>
page 30, "Electronic speed
limiter".
An improperly closed fuel filler cap may also cause the MIL light to
illuminate (only vehicles with gasoline engine)::::>

On-Board Diagnostics

Data Link Connector
( DLC )
On-Board Diagnostics monitors the components of your emission
control system. Each monito red component in you r engine system
has been ass igned a code. I n case of a malfunct ion, the component
wi ll be ident ified and the fau lt 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 refuelling, stop
the vehicle and make sure the fuel filler cap is properly closed (only
vehicles with gasoline engine)::::>
page 294.
In order to make an accurate diagnosis, the stored data can only be
displayed using special diagnostic equipment (generic scan tool for
OBD).
In order to connect the special diagnostic equipment, push the plug
into the Data Link Connector (DLC). The DLC is lo cated to the right of
the hood release
::::> fig. 21.
Your authorized Audi dealer or qualified workshop can interpret the
code and perform the necessary repair .•
Electronic speed limiter
Your vehicle may be factory equ ipped 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 veh icle. To reduce the risk of sudden tire
failure and loss of control if the vehicle is operated at excessive
speeds, your vehicle also 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 330.
If the engine control unit receives faulty vehicle roadspeed signals,
the Malfunction Indicator Lamp (MIL)
0 will illuminate . If this
occurs, contact the nearest authorized Aud i dea ler for ass istance.

Fuel supply and filling your fuel tank
Your vehicle fuel tank has an on-board refuelling vapor recovery
system . This feature helps to prevent fuel vapors from escaping from
the tank and polluting the environment while you refuel your vehicle.
In order to fill the tank properly while protecting the environment,
please follow this refueling procedure carefully.
& WARNING
Under normal operating conditions, never carry additional fuel
containers in your car. Gas canisters and other containers used to
transport fuel can be dangerous. Such containers, full or empty, may leak and could cause a fire in a collision. If you must transport
fuel to use for your lawn mower, snow blower, etc., be very careful and always observe local and state laws regarding the use, trans
portation and storage of such fuel containers. Make certain the
container meets industry standards (ANSI/ASTM F852 -86).
0 Note
Never drive your vehicle until the fuel tank is completely empty. The
ir regular supply of fuel can cause misfiring. Gasoline could enter the
exhaust system and damage the catalytic converter. •
Refuelling
Fig. 224 Right rear
vehicle side: Opening
the fuel filler flap Fig
. 225 Fuel cap
hooked on the opened
fuel filler flap
When adding fuel, the ignition and any cellular phones in the
vehicle must be switched
off. When activating the central
locking, the fuel filler flap is automatically unlocked or
locked. Refuel the vehicle with the ignition turned
off.
Taking the fuel cap off
- To open the fuel filler flap, press on the left side of the
flap ~ fig. 224 -arrow-.
- Unscrew fuel filler cap counter-clockwise and hang it on
the fuel filler flap~ fig. 225.
- Check the label on the inside of the fuel filler flap to deter
mine if the vehicle must be fueled with gasoline or diesel
fuel.
Refuelling procedure
- Insert the fuel nozzle from the gasoline pump into the
fuel filler neck as far as it will go.
- Select a medium refuelling rate so that the nozzle
switches off automatically when the tank is full.
Fuel supply and filling your fuel tank
(I) Tips
• Runn ing your eng ine while refuelling may cause vapors to escape
or even cause fuel to spill out of the tank. This would then shut off the
fuel nozzle before the tank is full.
• Do not refuel your vehicle with the ignition turned on. The fuel
gauge may otherwise not ind icate the correct fuel level after refuel
ling.
• Diesel vehicles* are equipped w ith a mechanism to prevent incor
rect fueling. They can only be fueled with diesel pump nozzles. A
worn, damaged, or improperly specified nozz le may not allow this
mechanism to open, thereby preventing refueling. If you cannot
insert the pump nozzle, rotate it in the tank opening. This should
open the mechanism and allow refueling. •
Unlocking the fuel filler flap by hand
You can open the fuel filler flap by hand if the power
locking system should fail.

TDI clean diesel
App lies to veh icles: w ith diese l eng ine
General information
On TOI clean diesel vehicles, an urea solution (AdBlue®) is injected
into the exhaust system before a specia l catalytic converter to reduce
nitrogen emissions.
The Ad Blue is stored in a separate tank in the vehicle and f illed during
maintenance intervals. Under norma l driving conditions, there will be
enough Ad Blue to last from one maintenance interval to the next.
Because of this, the scheduled maintenance intervals should always
be followed.
The Ad Blue usage accounts for approximately 0.5% to 1 % of the
diesel fuel that is us ed. The Ad Blue tank capacity is approximately 6
gallons (23 liters). ..,_
