Selective catalytic
reduction
General information
Applies to vehicles: wit h diese l en gi ne
On vehicles with selective catalytic reduction,
an urea solution (Ad Blue) is injected into the
exhaust system before a nitrogen oxide cata
lytic converter to reduce nitrogen emissions.
The Ad Blue is stored in a separate tank in the
vehicle . The Ad Blue usage accounts for ap
proximately 0.5% to 1.2% of the diesel fuel
that is used.
You must refill the Ad Blue or have it refilled
by your authorized Audi dealer or qualified
workshop as soon as the AdBlue refill mes sage appears in the instrument cluster
c;,page229.
A WARNING
Failure to heed Ad Blue refill information in
the instrument cluster can prevent the ve
hicle from being started and driven. If the
vehicle cannot be driven and an emergency
arises, persona l inju ry can occur.
- Always have the Ad Blue tank refilled well
before the tank ru ns dry.
@ Tips
-The instrument cluster display indicates
the distance remaining that can be driv
en
c;, poge 228. If the Ad Blue tank is
completely empty, the engine will not
start again after the ignition is switched
off.
- AdBlue is required by law to operate this
vehicle.

standard ISO 2224 1-1. Do not mix any
additives with the Ad Blue and do not di
lute it with water .
- AdBlue is not a diesel additive . Do not
add it to the diesel tank. If Ad Blue is
mixed w ith diesel fuel, it can lead to
damage to the engine and the Ad Blue
tank system. The Limited New Vehicle
Warranty does not cover such damage.
-Ad Blue attacks surfaces such as painted
vehicle components, plastic and carpet .
Remove the fluid as quickly as possible
with a damp cloth and plenty of cold wa
ter. If the Ad Blue has already crystal
li zed, use warm water and a sponge .

Engine oil
Engine oil specifications
The engine in your Audi needs the right kind
of oil.
The engine in your Audi is a sophisticated
powerplant that was built to exacting specifi
cations. This eng ine needs the right k ind of
engine oil that meets specifications regarding
quality and viscosity so that it can run
smooth ly and reliab ly. Choosing the right oil
and changing oil within the time and mileage
intervals printed in your vehicle's Warranty
&
Maintenance booklet matters a lot more to
day than it did years ago . Audi has developed
a specia l quality standard for engine oil that
will help assure that your vehicle's engine will
get the lubrication it needs for proper opera-
tion. .,..

names etc.) that conform to Audi oi l standard
VW 502 00 (vehicles with gasoline engine) or
VW 507 00 (vehicles with diesel engine).
C hang ing th e engin e oil
The engine oil and oi l filter must be changed
according to the m ileage (kilomete rs) and
time inte rva ls specified in yo ur vehicle's War
ranty
& Maintenance booklet. Do not exceed
these intervals -harmful deposits from old
engine oil can reduce engine performance and
can lead to expensive eng ine repairs.
Changing the o il at the recommended inter
va ls is so very important because the lubricat
ing properties of oi l decrease gradually during
norma l vehicle use . If you are not sure when
you have your oi l changed, ask your author
ized Audi Service Advisor.
Under some circ umstances the engine oi l
should even be changed more frequently .
Change o il more often if you drive mostly
short distances, operate the vehicle in dusty
areas or mostly under stop-and -go traffic con
d itions, or when you use your veh icle where
temperatures stay below freezing point for l ong periods.
Detergent addit ives in the o il w ill make fresh
oil look dark after the eng ine has been run
n ing for a short time. This is norma l and is not
a reason to change the o il mo re often than
r ecommended.
Damage or ma lf u nction s du e to lac k of
ma intenance
It is essential that you change your oil at the
recommended interva ls using only engine oil
that complies with Audi oil standard
VW 502 00 (vehicles with gasoline engine) or
VW S07 00 (veh icles with diese l engi ne). Yo ur
L im ited New Vehicle Warra nty does not cover
damage or ma lfunctions due to failure to fol

· Engine oil consumption
The engine in your vehicle depends on an ade
quate amount of oil to lubricate and cool all
of its moving parts.
In order to prov ide effective lubrication and
cooling o f inte rna l engine components, all in
ternal combustion engines consume a certain
amount of oil. Oil consumpt ion varies from
engine to engine and may change sign ificantly
over the life of the engine. Typically, engines
with a spec ified break-in period (see
Q page 205) consume more oil during the
break-in pe riod than they consume after o il
consump tion has stabilized.
Under normal cond itions, the rate of oi l con
sumption depends on the quality and viscos ity
of the oil, the RP M (revolut ions per minute) at
which the engine is operated, the ambient
tempe rature a nd road conditions. Furt her fac
tors are the amount of oil dilut ion from wa ter
condensation or fue l residue and the oxida
tion level of the oi l. As any engine is subject to
wear as mi leage builds up, the oil consump
tion may increase over time until replacement
of worn components may become necessary.
With a ll these variab les coming into p lay, no
standard rate of oil consumpt ion can be es
tablished or spec ified. There is no alternative
to regular and frequent check ing of the o il lev
el, see
Not e.
If the yellow engine oil level warning symbo l
in the instrument cluster
II lights up, you
shou ld check the oil leve l as soon as possib le
