Fuel Petrol grade
Applies to: vehicles with petrol engine
The correct grade of petrol is Listed inside the
fuel tank flap.
The vehicle is equipped with a catalytic converter
and must only be run on unleaded petrol. Petrol
must be sulphur-free and must comply with the
EN 228 standard. You can fuel your vehicle with
fuels containing a maximum of 10% ethanol
(ElO). The petrol grades have different octane
ratings (RON).
The following headings relate to the sticker on
the inside of your vehicle's tank flap:
Unleaded fuel only RON/ROZ 95 Super,
Premium or min. RON/ROZ 91 Normal
The use of premium petrol (95 RON) is recom
mended. If that type of fuel is not available, reg
ular petrol (RON 91) can be used with a slight
loss of power.
Unleaded fuel only, min. RON/ROZ 95
Super, Premium
Premium petrol (at least 95 RON) must be used.
If premium petrol is not available, the engine can
be run on regular petrol with 91 RON as an emer
gency measure. In this case only use moderate
engine speeds and a light throttle. Fill up with
premium or Super Plus petrol as soon as possi
ble.
Unleaded fuel only RON/ROZ 98 Super Plus
or min. RON/ROZ 95 Super, Premium
The use of Super Plus petrol (98 RON) is recom
mended. If that type of fuel is not available, pre
mium petrol (RON 95) can be used with a slight
loss of power.
If premium petrol is not available, the engine can
be run on regular petrol with 91 RON as an emer
gency measure. In this case only use moderate
engine speeds and a light throttle. Fill up with Checking
and topping up fluids
premium or Super Plus petrol as soon as possi
ble.
CD CAUTION
- Do NOT fuel your vehicle with high-ethanol
fuel blends (e.g. ESQ or E85). This will dam
age the fuel system.
- Just one tank of leaded fuel or fuel with
metallic additives will permanently impair
the efficiency of the catalytic converter.
- You should use only petrol additives which
have been approved by Audi. Additives with
so-called octane boosters or antiknock addi
tives can contain metallic additives that
cause significant damage to the engine and
the catalytic converter. Do not use such ad
ditives.
- Metal-based fuels, which can be identified
from the marking on the fuel dispenser,
must not be used. LRP fuel (lead replace
ment petrol) also contains high concentra
tions of metallic additive. Risk of engine
damage!
- High engine speed and full throttle can
damage the engine when using petrol with
an octane rating lower than the correct
grade for the engine.
((D Note
- You can use higher octane fuel than your en
gine requires.
- In countries where sulphur-free fuel is not
available, you may use low-sulphur fuel in
stead.
Diesel fuel
Applies to: vehicles
with
diesel engine
Please note the information on the inside of the
fuel tank flap.
The use of sulphur-free diesel complying with
the EN 590 standard is recommended.
Diesel can thicken at very low temperatures,
which can result in problems starting the engine
or prevent the engine from running smoothly.
For this reason, filling stations in some countries
offer winter-grade diesel fuel during the cold 1)11,,

months so that you can continue to operate your
vehicle reliably. Ask at your filling station wheth
er the diesel fuel available there is suitable for
the current conditions and for the temperatures
which could potentially occur.
CD CAUTION
- Never use FAME fuels (biodiesel), petrol,
heating oil, thinners or any other fuels or
additives, as these could cause serious dam
age to the fuel system and the engine.
- Never start the engine if you fill up with the
wrong type of fuel, as this could damage
the fuel system and the engine. Obtain pro
fessional assistance.

Fig. 208 Vehicle as seen from the rear right: Inserting the
filler nozzle
The fuel tank flap is unlocked and Locked auto
matically by the central Locking system.
... Press
the tank flap -arrow- ¢ Fig. 207 to open
it. Your vehicle has a new self-sealing fuel tank
without a tank cap.
242 ...
Insert the filler nozzle into the fuel filler neck
as far as the stop ¢ Fig. 208 and ensure it is
properly engaged .
... Start refuelling. When the automatic filler noz
zle is operated correctly it will switch itself off
as soon as the tank is full. Do not try to put in
more fuel after the nozzle cuts out, as this will
fill the expansion chamber in the fuel tank.
.., When the fuel filler pump switches itself off,
wait for 5 seconds before pulling out the filler
nozzle so that any remaining fuel can flow into
the tank opening.
... Close the tank flap. Make sure you hear it click
into place.
The correct fuel grade for your vehicle is given on
a sticker on the inside of the tank flap. Further
notes on fuel ¢ page 241.
The tank capacity of your vehicle is given in the
Technical data section ¢ page 288 .
A WARNING
Fuel is highly inflammable and can cause seri
ous burns and other injuries.
- When filling your tank or a spare fuel canis
ter with fuel, do not smoke and keep away
from naked flames -risk of explosion!
- Observe all relevant statutory regulations
on using, storing and transporting spare
fuel canisters.
- For safety reasons we do not recommend
carrying a spare fuel canister in the vehicle.
The canister could become damaged in an
accident and Leak.
- If, in exceptional circumstances, you have to
carry a spare fuel canister, please observe
the following warnings:
- Never fill fuel into the spare fuel canister
with the canister placed in or on top of the
vehicle. An electrostatic charge could
build up during filling, causing the fuel va
pour to ignite -risk of explosion! Always
place the canister on the ground to fill it.
- Insert the filler nozzle as far as possible
into the spare fuel canister .
- If the spare fuel canister is made of metal,
the filler nozzle must be in contact with �

and topping up fluids
- Switch off the warm engine. Wait for a few mi
nutes for the oil to drain back into the sump.
- Open the bonnet ¢page 245.
- Pull out the oil dipstick ¢page 246, Fig. 214,
wipe it with a clean cloth and insert it again,
pushing it in as far as it will go.
- Then pull the dipstick out again and check the
oil level ¢table on page 248.
- If the oil level is too low, add more engine oil.
Markings on oil dipstick ¢ Fig. 215
@ When
the oil Level is near the marking @
you must top up the engine oil. Please refer
to ¢ 0.
@ Do NOT add engine oil.

Drive to a qualified workshop without delay
and have the engine oil changed ¢0.
Topping up the engine oil
- Unscrew the cap "E::71 ¢Fig. 216from the oil fill
er opening ¢ page 246, Fig. 214.
- Carefully add 0.5 litres of suitable engine oil
¢page 247.
-After two minutes check the oil level once
again.
- If the oil level is too low, add a smaller quantity
of engine oil. The level must always be below
the marking @¢Fig. 215 ¢0.
- Screw the oil filler cap "E::71 back on and push
the dipstick all the way in.
A WARNING
- Ensure that no engine oil comes into contact
with hot engine components when topping
up: this could cause a fire.
- The oil filler cap must be properly closed to
prevent oil from squirting onto the hot en
gine or exhaust system while the engine is
running -risk of fire!
- Wash your skin thoroughly if it comes into
contact with engine oil.
248 CD
CAUTION
- The engine oil must never drop below the
marking (!)¢ Fig. 215 -risk of engine dam
age!
- When topping up the engine oil, make sure
that the oil level is not above the marking
@ ¢Fig. 215, as this may result in damage
to the catalytic converter or to the engine.
Do NOT start the engine. Contact a qualified
workshop to extract the engine oil if neces
sary.
- Applies to vehicles which have an oil dip
stick with area® ¢Fig. 215: If you run your
vehicle on diesel fuel of poorer quality than
EN 590 standard fuel, the fuel can get into
the engine oil. In this case, the oil Level
gradually rises and the quality of the engine
oil decreases. Once the oil level has reached
the marking @or the indicator lamp II
has come on, the engine oil level must not
be corrected by extracting the surplus oil -
risk of engine damage! The engine oil must
be changed ¢ page 18.
- No additives should be used with engine oil.
Any damage caused by the use of such addi
tives would not be covered by the factory
warranty.
® For the sake of the environment
- Never pour engine oil down drains or into
the ground.
-Always observe statutory requirements
when disposing of empty oil canisters.
@ Note
Depending on how you drive and the condi
tions in which the car is used, oil consumption
can be up to 0.5 Ltr./1000 km. Oil consump
tion on RS models can be up to 0.8 ltr./1,000
km. Oil consumption is likely to be higher for
the first 5,000 km. For this reason the engine
oil level must be checked at regular intervals,
preferably when filling the tank and before a
journey.
