Selective catalytic
reduction (AdBlue/DEF)
General information
Applies to: vehicles with selective catalytic reduct ion
In vehicles with selective catalytic reduction, a
urea solution (AdBlue/DE F) 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 Flu id) . The informat ion that fo llows w ill
u se the name Ad B lue .
The Ad Blue is carried in a separate tank in the ve­
hicle. The Ad Blue usage accounts for approxi­
mately 1.0% to 4.0% of the diesel fuel that is
u sed.
When a message about refilling the AdBlue ap­ pears in the instrument cluster display, you must
refill the Ad B lue yourse lf or have it refilled by an
authorized Aud i dea ler or authorized Audi Serv ice
Fac ility<::>

ue tank is comple tely emp ty, the eng ine will
not s tart again after the ign ition is switched
off.
-Ad Bl ue is required by law to ope rate th is ve­
hicle.
Messages in the instrument cluster display
App lies to: vehicles wi th selective catalyt ic reduct ion
The display indicat es if the Ad Blue level is low or
if there
is a system malfun ction.
AdBlue level low
You w ill be informed in the instrument cluster
display if the AdBlue in the tank drops below a
ce rtain level. Add at a minimum the amount of
AdBlue shown in the message:

After filling
The vehicle must be driven so that the system

range of O mi (0 km) was shown in the display ,
switch the ign ition on for about 3 0 seconds be­
f ore star ting the engine .

Ad Blue in the tank can free ze at very low tem­
pe ra tures. If this happens, the system will
no t detect t hat the Ad Bl ue was refilled and i t
wi ll continue to inform you of the low Ad Blue
Ch eck ing and Filling
level. The message t urns off as soon as the
tank thaws out again .
Emissions control
systems
Catalytic con verter
Applies to: vehicles with gasoline engines
T he vehicle may only be driven with un leaded
gasoline, otherwise the catalytic converter will be
destroyed.
Never drive until the tank is compl ete ly empty .
The irregu lar supply of fuel that resu lts from that
can cause eng ine misfires. Uncombusted fuel will
enter the exhaust system, which can cause over­
heating and damage to the catalytic converter .
Diesel particulate filt er
Applies to: vehicles with diesel engines
The diese l particu late filter filters near ly all of
the soot particles out of the exhaust. The filter
cleans itself automatically under norma l driving
condit ions. If the filter cannot clean itself (for ex­
ample, because you are only driving short distan ­
ces), the filter becomes clogged with soot and
the
1\1 i ndicato r light for the diese l part iculate
filte r tu rns on
c;> page 33.
_& WARNING
The tempera ture of the exhaus t sys tem is
high, bot h when driv ing and a fter stoppi ng
the engine.
- Never tou ch the e xhaust tail pipes once they
have become hot. This cou ld res ult in burns .
- Do not par k your veh icle over flamm ab le
materia ls such as grass or leaves because
the high temperature of the emissions con­ trol system (catalytic converter or diesel particu late filter) cou ld start a fire.
-Do not app ly underbody protectant in the
exhaust system area, beca use this increases
the risk of f ire.
