Selective catalytic
reduction (AdBlue/DEF)
General information
App lies to: vehicles with selective catalytic reduct ion
In vehicles with selective catalytic reduction, a
urea solution (AdBlue/DEF) is injected into the
exhaust system in front of a nitrogen oxide cata­ l ytic converter to reduce nitrogen em issions. The
urea solution is known as Ad Blue or DEF (Diesel
Exhaust Fluid) . The informat ion that follows w ill
u se the name Ad B lue .
The Ad Blue is carried in a separate tank in the ve­
hicle. The AdBlue consumption depends on the
dr iv ing behavior and veh icle operat ing cond i­
tions .
It is within a range of 1.0 L -3.0L every 600
miles (1,000 km). In some cases, the consump­
tion may a lso differ from this range depending
o n the dr iving behavior and vehicle operat ing
cond it ions.
When a message about refi lling the AdBlue ap­
pears in the instrument cl uster display, you must
refi ll the Ad B lue yourse lf or have it refilled by an
authorized Aud i dea le r o r a utho rized Audi Service
Facility

Observe the safety precautions¢ A in Working
in the engine compartment on page 319.
~ Park your vehicle on a level surface.
~ Shut the engine off when it is warm.
~ Switch only the ignition back on.
~ Wait approx imately two minutes.
~ Select in the Infota inment system: the I MENU I
button > Ve hicle > left contro l button > Ser vic e
& chec ks > Oil level.
~ Read the oi l level in the display . Add engi ne oil
if th e ba r in the oil leve l ind icator is j ust before
"min" ¢
page 323.
{U) Note
The engine o il leve l must not be unde r the
"min" marking, as this will increase the risk of
engine damage .
(D Tips
The oil level indicato r in the display is on ly an
informationa l display . If the o il level is too
low, a minimum oi l warning appears in the in ·
strument cluster. Add oi l and close the hood.
The current oil leve l is d isplayed in the Info­
tainment system the next time the ignition is
sw itched on.
(D Tips
The engine oil consumption may be up to
0.5 quart/600 m iles (0.5 liter/1,000 km), de­
pending on driving style and operating condi­
tions. Consumpt ion may be h igher during the
first 3,000 miles (5,000 km). Because of this, the engi ne oil level m ust be chec ked regular·
Ly. It is best to c hec k each t ime yo u refuel
your veh icle and before long dr ives.
322
- In order to prov ide e ffective lubrication and
cooling of interna l engine components, a ll
internal comb ustion engines consume acer ­
tain amount of oil. Oil consumption var ies
from engine to eng ine and may change sig­
nificantly over the life of the engine. Typi·
cally, eng ines with a specified break-in per i·
od consume mo re o il during the break-in pe·
r iod than they consume afte r oil cons ump·
t ion has s tabilized.
- Under no rma l co nd it ions, the rate of oil
c ons umption depends on the q ual ity and
vis cos ity of the oil, the RPM (revo lutions per
min ute) a t which the engine is operated, the
ambient temperature and road conditions .
Further factors are the amount of oi l di lu ­
t ion from water condensation or fuel resi­
due and the oxidation level of the oil. As any
eng ine is subject to wear as m ileage bu ilds
up, the oil consumption may increase over
t ime until replacement of worn components
may become necessa ry.
- With all these var iables comi ng into play,
no standard rate of o il consumption can be
established o r spe cified. There is no alter na­
t ive to c hec king the oil leve l reg ularly and
frequently.
- If you have the impress io n your e ng ine co n­
s u mes excessive amou nts of oi l, we recom ­
mend that yo u consult an authorized A udi
dea ler to have the cause of your concern
properly diagnosed . Keep in mind that the
acc urate measurement of o il cons umption
requires great care and may take some
