Check ing and F illing
Selective catalytic
reduction (AdBlue)
General information
Applies to vehicles: with diesel engine
In vehicles with selective cata lytic reduction, a
urea solution (AdB lue) is injected into the ex­
haust system before a nitrogen oxide catalytic
converter to reduce nitrogen emissions.
Ad B lue is the marketing name for Diesel Exha ust
Fl uid (DEF).
The AdBl ue is carried in a separate ta nk in the ve­
hicle. The Ad Blue usage accounts for approxi­
mate ly 0.5% to 1.2% of the diesel f uel that is
used .
W hen a message about refilling the Ad B lue ap­
pears in the instrument cluster disp lay, you must
refill the Ad Blue you rself or have it refilled by an
author ized Audi dealer or authorized Audi Service
Facility ¢
page 235.
A WARNING
-
Failure to heed AdBlue refill informat ion in
the instrument cluster can prevent the vehicle
from being started and dr iven . If the vehicle
cannot be driven and an emergency arises,
perso na l in jur y can occur.
- Always have the AdBlue tank refilled well
before the tank runs dry .
(D Tips
-The instrument cluster display indicates the
distance rema ining t hat can be driven
¢ page 234. If the AdBlue tank is com­
plete ly empty, the engine wi ll not start
again after the ignition is sw itched off.
- Ad B lue is req uired by law to operate this ve­
hicle.

0 > co ,...., Read and follow the WARNINGS before check­
ing anything in the engine compartment
c::> page 236, Working in the engine compart­
ment.
.. Turn the engine off.
.. Unscrew the engine oil filler opening cap~
c::>fig.197, c::>page239, fig.193 .

c::> page 242, Checking the engine oil level .
.,. Add o il, if necessary.
.. Close the engine oil filler cap and push the dip­
stick all the way in .
A WARNING ,--
- When adding oil, do not let oil drip onto hot
engine components . There could be risk of a
fire.
- You must secure the cap on the oi l filler
opening correctly so that oil does not leak
out onto the hot engine and exhaust system
when the eng ine is running, because this is
a fire hazard.
- Always clean skin thoroughly if it comes into contact with engine oil.
(D Note
-Applies to vehicles with a gasoline engine:
the oil level cannot be above the
0 range
c> page 242, fig. 195 or else yo u risk dam­
aging the catalytic converter and the en­
gine . Contact an authorized Audi dealer or
authorized Audi Serv ice Facility to have ex­
cess oil extracted if necessary .
-Applies to vehicles with a diesel eng ine: the

Checking and Filling
{® For the sake of the environment
-Oil shou ld never enter the sewer system or
come into contact with the ground.
- Pay attention to lega l requirements when
disposing of empty oil containers .
Changing the engine oil
We recommend that have your oil changed by an
authorized Audi dealer or a qualified service sta ­
tion .
Before you check anything in the engine compart­
ment,
always read and heed all WARNINGS
c::> page 236.
The engine o il must be changed according to the
intervals specified in your Warranty
& Mainte­
nance book let. This is very important because the
lubricating properties of oil diminish gradua lly
during norma l vehicle use.
Under some circumstances the engine oil shou ld
be changed more frequent ly. Change oil more of­
ten if you drive mostly short distances, operate
the vehicle in dusty areas or under predominantly
stop-and-go traff ic conditions, or have your vehi­
cle where temperatures remain below freezing
for extended periods.
Detergent additives in the oi l will make fresh oil
look dark after the engine has been running for a
short time. This is normal and is not a reason to
change the oil more often than recommended.
Because of the problem of proper disposal, along
with the special tools and necessary expertise re­
quired, we strongly recommend that you have
your o il changed by an authorized
Audi dealer or
a qualified service stat ion.
If you choose to change your oil yourself, please
note the following important information:
A WARNING ,-~
To reduce the risk of personal injury if you
must change the engine oil in your vehicle
yourself:
- Wear eye protection.
