Checking and topping up fluids
Selective catalytic
reduction (AdBLue/DEF)
General notes
Applies to: vehicles with selective catalytic reduction
On vehicles with selective catalytic reduction, a
urea solution (AdBLue/DEF) is injected into the
exhaust system upstream of
a
NOx catalytic
con­

verter in order to reduce nitrogen oxide emis­

sions.
The urea solution is known under the name
of AdBlue or DEF (Diesel Exhaust Fluid). The term
AdBlue is used below.
The AdBlue is held in a separate tank on the
vehi­

cle.
AdBlue consumption is approximately 1.0 -
2.5% of diesel fuel consumption.
As soon as a message appears in the instrument
cluster display reminding you to refill AdBlue,
you must refill the AdBlue tank or have this done
by
a
qualified workshop
^>page
293.
Checking the remaining range
The remaining (estimated) range for the current

AdBLue
level can be displayed on the on-board
computer:
- Vehicles with analogue instrument cluster

•=>
page 20.
- Vehicles with virtual cockpit*
<$page
19.
-The instrument cluster display will
tell
you
how far you can drive before the tank runs
dry
•=>page
292. If the AdBlue tank runs
dry, the engine cannot be started again af­
ter you switch off the ignition.
-The use of
AdBLue for
the operation of this
vehicle is required by Law.
Instrument cluster display
Applies to: vehicles with selective catalytic reduction

The
display informs you if the AdBlue level is too
low or if a system malfunction occurs.
Low AdBlue level
You will be informed if the amount of AdBlue in
the tank falls below a certain
Level.
Add at least
the minimum (smaller) amount of AdBlue

shown:

Filling the wrong fluid / system fault
If
you
fill the AdBlue tank with a fluid other than
AdBlue and the system detects that the wrong
fluid has been added or there is a system fault, a
driver message will appear.

|
AdBlue:
system fault. No restart in x km!
See owner's manual
This message tells you the maximum distance

that
you can drive. Drive to a qualified workshop
and have the fault rectified. Otherwise, after driv­
ing the maximum distance and switching off the
engine, you will not be able to restart the car.

AdBlue:
system fault. No restart! See own­
er's manual
This message appears if the system detects that
the tank has been filled with the wrong fluid or if
there is a system fault. Drive to the nearest quali­
fied workshop without delay and have the fault

rectified.
Otherwise, you will not be able to re­
start the car after you switch off the engine.

Fig.
241 Vehicle as seen from the rear right: Unscrewing
the AdBlue cap
The AdBlue filler neck is located immediately be­
side the diesel filler neck. Add at least the
amount of AdBlue displayed in the instrument
cluster. If
you
do not refill this amount of
fluid,

the system may not detect that the tank has
been refilled and it may not be possible to restart
the engine. You can refill with a maximum of 12

litres.

Important: A message in the instrument cluster
display informs you if
you
need to refill AdBlue.

•
Park the vehicle on a level surface.

•
Switch off the ignition.
• Open the tank flap
<^>page
290.

•
Unscrew the cap on the filler neck
anti-clock­

wise

A WARNING
AdBlue can cause irritation to the
skin,
eyes,
and respiratory organs. Wash thoroughly with
clean water should you come into contact
with this
fluid.
Seek medical assistance if nee­

ded.

© CAUTION
- Use only
AdBLue
that complies with the ISO
22241-1 standard. Do not mix AdBlue with
additives and do not dilute it with water.
- AdBlue must not be added to the diesel
tank, and diesel must not be added to the
AdBlue tank. Never start the engine if you
fill up with the wrong type of
fuel,
as this
could damage the tank system and the en­

gine.
Obtain professional assistance.
-AdBlue attacks surfaces such as paintwork,
plastic veneer and carpets. Remove spilt
flu­

id as soon as possible with a damp cloth and
plenty of water. If the AdBlue has already

solidified,
use warm water and a sponge.
Residues of AdBlue solidify after
a
while if
they are not removed and can damage the
affected surface.
- Do not keep refill bottles or canisters in the
vehicle, as AdBlue can leak and damage the
vehicle interior.
- Keep AdBlue away from clothing. Wash
thoroughly with clean water should you
come into contact with this
fluid.

\J
Note
Please follow the AdBlue manufacturer's in­
structions for storage and use.
Refilling AdBlue from a filler nozzle
Applies to: vehicles with selective catalytic reduction

•
Open the tank flap
^>page
290.

*•
Unscrew the cap on the filler neck
anti-clock­

wise
^>page
293, Fig. 241.

*•
Fill up with AdBlue until the first time the filler
nozzle cuts off the supply
•=>(]}.

•
Put the tank cap back on
opage
294, After re­
filling.
CAUTION
- The handle of the filler nozzle must point
downwards when filling the tank. Otherwise
the filler nozzle will not cut off the supply
automatically
^0
in Preparations on
page 293.
- You should stop refilling the first time the
filler nozzle automatically cuts off the sup­
ply. Otherwise the level of AdBlue in the
tank may be too high and AdBlue could
overflow

Wheels
more tyres, the driver is alerted by an indicator
lamp
0H ar|d a
message in the instrument cluster
display. If only one tyre is affected, the display
will indicate its position.
Each time you change a tyre, change the wheels
round or change the tyre pressures on your
vehi­

cle (e.g. when switching from partial load to full
load and vice-versa), you must store the new tyre
pressures in the menu display
<=>page
311.
Mon­

itoring of the tyre pressures is based on the tyre
pressures you have stored. The inflation pres­
sures recommended for your vehicle are given on
the tyre pressure sticker
opage
307, Fig. 253.
The rolling circumference and vibration can
change and cause a tyre pressure warning if:
- The inflation pressure in one or more tyres is
too low.
- The tyre has suffered structural damage.
- The wheels were changed or the tyre pressures
were changed and the new tyre pressures were
not stored
<>page
311.
- The vehicLe load is not balanced (more load on
one side).
- There is more load on the wheels of one of the
axles (e.g. when towing a trailer or driving up
or down a gradient).
- You are driving with snow chains.
- You are driving with the temporary spare

wheel*.

- Only one wheel of an axle has been changed.

Check and change or repair the tyre(s). Check and
adjust the tyre pressures again on all four
wheels. Then store the tyre pressures in the

appears and the indicator

LampBH in the
instrument cluster dispLay flashes
for approx. one minute and then remains lit after
you have switched on the ignition or while you
are driving, there is a fault in the system. Check
and adjust the tyre pressures for all four tyres
and store the
new
tyre pressures
•=>page
311. If
the indicator lamp does not go out or if it comes
on again after
a
short time, drive to a qualified
workshop without delay and have the fault
recti­

fied.

®
No
- If
a
malfunction occurs in the ESC/ABS sys­

tem,
the tyre pressure loss indicator may al­
so be out of action.
-When driving with snow chains, a system
malfunction can occur.
-The tyre pressure Loss indicator on your Audi
is specially matched to "Audi Genuine Tyres"

^>page
305. We recommend that you use
these tyres.
- The tyre pressure Loss indicator can only
monitor the pressures of the tyres fitted on
the car. For this reason please regularly
check the tyre pressure of the spare wheel
in the luggage compartment so it can be
used if required.

A
WARNING
- If the tyre pressure loss indicator appears in
the instrument cluster display, slow down
immediately and avoid any severe braking or
steering manoeuvres. As soon as you can do
so safely, stop and check the tyres and the
tyre pressures.
- It is the driver's responsibility to ensure that
the tyre pressures are correct. For this rea­
son you must check the tyre pressures
regu­

larly.
- Under certain conditions (e.g. driving at
high speeds, on ice and snow or on poor
road surfaces) the tyre pressure loss indica­
tor may not appear immediately.
- The use of run-flat tyres on your vehicLe is
NOT authorised! Unauthorised use can cause
an accident or damage your vehicle.
