The correct grade of petrol is listed inside the
fuel tonk flop.
The vehicle is equipped with a catalytic con-
verter and must only be run on unleaded pet-
rol. The petrol must comply with the EN 228
or DIN 51626-1 standard and must be sul-
phur-free. You can fue l your vehicle with fuels
containing a maximum of 10% ethanol (ElO).
The petrol grades have different octane rat-
ings (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,
regular 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 prem ium petrol is not available, the engine
can be run on regular petrol with 91 RO N as
a n
emergency measure.
In this case on ly use
moderate engine speeds and a light t hrottle.
Fill up with premium or Super Plus petrol as
soon as possible.
Unleaded fuel only RON / ROZ 98 Super

CAUTION
- Do NOT fuel your vehicle with high-etha-
nol fuel blends (e.g. E50 or E85). This
will damage the fuel system.
- Just one tank of leaded fuel or fuel with
metallic additives will permanently im-
pair the efficiency of the catalytic corn-
verter.
- You should use only petrol additives
which have been approved by Audi. Addi-
t ives with so-called octane boosters or
antiknock add itives can contain met a llic
add itives that cause significant damage
to the engine and the catalytic converter.
Do not use such additives.
- Metal-based fuels, which can be identi-
fied from the marking on the fuel dis-
penser, must not be used. LRP fuel (lead
replacement petrol) also contains high
concentrations 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 cor-
rect grade for the engine.
