Selective catalytic reduction (AdBlue)
General information
Applies to vehicles: with selective catalyt ic reduction
In vehicles with se lective cata lytic reduction, a
urea solution (Ad B lue) is injected into the ex ­
haust system before a nitrogen ox ide catalytic
converter to reduce nitrogen emissions.
The AdBlue is carried in a separate tank in the ve­
hicle. The Ad Blue usage accounts for approxi­
mately 0.5% to 2.5% of the diesel fuel that is
used.
When a message about refilling the Ad B lue ap­
pears in the instr ument cluster disp lay, you must
refill the Ad Blue yourself or have it refilled by an
author ized Audi dealer or author ized Audi Service
Facility

(l) Tips
-The display indicates the distance remain ing
that can be driven
¢page 217. If the AdBl­
ue tank is complete ly empty, the engine w ill
not sta rt again after the ignition is sw itched
off.
- Ad Blue is req uired by law to operate this ve­
hicle.

Filling AdBlue
Applies to veh icles: w ith selective cata ly ti c reduction
Fig. 193 Right rear side of the vehicle: removing the AdBl­
ue cap
The Ad Blue tank opening is located near the die­
sel tank opening. Add at least 1 gallon (3.8 lit­
ers) of Ad Blue. This is the minimum amount re­
quired to ensure the system detects the refilling
and to start the engine. You can fill a maximum
of 6 gallons (23 liters).
Requirement: The request to add Ad Blue must
appear in the instrument cluster display.
• Switch the ignition off.
• Open the tank door
r::!) page 215.
• Turn the filler neck cap counter-clockwise using
the wheel wrench from the vehicle tool kit to
remove it
¢ fig . 193.
• Fill the Ad Blue with the bottle¢ page 218 or
the canister ¢
page 219.
A WARNING
AdBlue can irr itate the skin, eyes and resp ira­
tory system. If there is contact with the fluid,
flush immediately with plenty of water. Con­ sult a physician if necessary.
CD Note
- Only use Ad Blue that conforms to the
standard ISO 22241-1. Do not mix any addi­
tives w ith the AdBl ue and do not d ilute it
wi th water.
- Do not add Ad Blue to the diesel ta nk or add
diesel f uel to the AdBlue tan k. Do not start
the engine under any circumstances if the
wrong fue l is filled in the tank. There is a
risk of damaging the fuel tank system and
218
the engine . See an authorized Audi dea le r or
authorized Audi Service Facility for assis­
tance.
- Ad Blue attacks surfaces such as painted ve­
hicle components, p lastic and carpet. Re­
move the fluid as quickly as possible with a
damp cloth and plenty of cold water. If the

Using the prope r engine oil is important for the
functiona lity and service life of the eng ine. Your
engine was factory-filled with a high -quality oil
which can usually be used throughout the entire
year.
@ Note
Your Limited New Vehicle Warranty does not
cover damage or malfunctions due to failure
to follow recommended maintenance and use
requirements as set forth in the Audi Owner's Manual and Warranty
& Maintenance booklet.
- Use only a high quality eng ine oil that ex-
pressly complies with the Aud i oil quality
standard specified for your vehicle's engine.
Using any other oil can cause serious engine
damage .
- Do not mix any lubricants or other additives
into the engine oil. Doing so can cause en­
gine damage.
(D Tips
If you need to add oil and there is none availa­
ble that meets the Audi o il quality standard

Ch eck ing and Filling
Engine oil consumption
The engine in your vehicle depends on on ade­
quate amount of oil to lubricate and cool oil of
its moving ports.
In order to provide effect ive lubrication and cool­
i ng of internal engine components, all internal
combust ion eng ines consume a certa in amount
of oil. Oil consumption varies from eng ine to en­
gine and may change s ign ificantly ove r the life of
the engine. Typ ica lly, engines w ith a specified
break-in period (see
¢ page 197) consume more
oi l during the break -in period than they consume
after oil consumption has stabilized.
Under normal cond itions, the rate of oil con­
sumption depends on the q uality and viscosity o f
the oil, the RPM (revol utions per minute) at
which the engine is operated, the ambient tem­
perature and road condit ions. Further factors are
the amount of oil dilution from water condensa­
tion or fuel residue and the oxidation level of the o il. As any engine is subject to wear as mileage
builds up, the oil consumption may increase over
time unt il replacement of worn components may
become necessary.
With all these variables coming into play, no standard rate of o il consumption can be estab­
li shed or spec ified . T he re is no alte rnative to reg­
u la r and frequent checking of the oi l level , see
Note .
If the yellow engine o il leve l warning symbo l in
the instrument cluster
II lights up, yo u should
c h eck the o il level as soon as possible

venience

Before you check anything in the engine com-
partment, always read and heed all WARN­

ment on page 220.
(D Note
Driving wit h an insufficient oil level is likely to
cause severe damage to the eng ine. ..,.

Checking and Filling
@ Tips
-The oil pressure warning display. is not
an indicator of the oil level. Do not rely on
i t. Instead , check the oil level in your en­
gine at regular intervals, preferably each
time you refuel, and always before going
on a long trip.
- If you have the impression your engine con­
sumes excessive amounts of oil, we recom­
mend that you cons ult an autho rized Aud i
dealer to have the cause of your concern
properly diagnosed . Keep in mind that the
accurate measurement of oil consumption
requires great care and may take some
time. An authorized Audi dealer has instruc­
tions about how to measure oil consump­
tion accurately.
Checking the engine oil level
Fig. 198 D is play: Oil level indicator
Read oil level
• Park yo ur vehicle so that it is hor izonta lly level.
• Shut the engine off when it is at operating tem-
perature.
• Switch only the ignition back on.
• Wait approx . two minutes.
• Se lect:
ICARI function button > Oil level. Or
• Se lect:
ICARI funct ion button> Car systems *
control button > Servicing & checks > Oil level.
• Read the oil level in the radio or MMI* Display
¢
fig. 198. Add engine o il if the bar of the oil
level indicator is near "Min"
Q page 224.
The oil level needs to be checked at regular inter­
vals. The best times to do this are whenever you refuel and pr ior to long trips .
224
Depending on the way the vehicle is driven and
the operating conditions, oil consumption can be
up to a 1/2 quart per 600 miles (0.5 liter per
1,000 km). Consumption may be higher w it hin
the first 3,000 miles (5,000 km).
(D Tips
The o il level indicator in the radio or MMI*
D isp lay is only an information display. If the
oil level is too low, a m inimum oil warning ap­
pears in the instrument cluster. Add oil
