Selective catalytic
reduction (AdBlue/DEF)
General information
Appl ies to: vehicles with selective catalytic reduct ion
In vehicles with selective catalyt ic reduction, a
u rea solution (AdBlue/DEF) is injected into the
exhaust system before a nitrogen oxide catalytic
conve rter to reduce nitrogen em issions . The urea
solution is known as Ad Blue or D EF (Diesel Ex­
haust Fluid) . Ad Blue is used in the follow ing .
The Ad Blue is carried in a separate tank in the ve­ hicle. The AdBlue usage acco unts for approxi ­
mately 0 .5% to 2 .5% of the diese l fuel that is
u sed .
When a message about refilling the AdBlue ap­ pears in the instrument cl uster display, you must
ref ill the Ad B lue yourself or have it refilled by an
autho rized Aud i dea le r o r a uthorized Audi Serv ice

Checking and Filling
& WARNING
AdBlue can irritate the skin, eyes and respira­tory system. If there is contact with the fluid,
flush immediately with plenty of water . Con­
sult a physician if necessary.
(D Note
- Only use Ad Blue that conforms to the
standard ISO 22241 -1. Do not mix any addi ­
tives with the Ad Blue and do not dilute it
with water.
- Do not add Ad Blue to the diesel tank or add diesel fuel to the Ad Blue tank. Do not start
the engine under any circumstances if the
wrong fuel is filled in the tank. There is a
risk of damaging the fuel tank system and
the engine. See an authorized Audi dealer or
authorized Audi Service Facility for assis­
tance.
- AdBlue attacks surfaces such as painted ve­
hicle components, plastic and carpet. Re­
move the fluid as quickly as possible with a
damp cloth and plenty of cold water. If the
Ad Blue has already crystallized, use warm
water and a sponge . AdBlue residue that is
not removed will crystallize and can damage
the affected surface.
- Do not store refill bottles or canisters per ­
manently in the vehicle. If the container
leaks, the escaping AdBlue could damage
the vehicle interior.
- Do not allow AdBlue to come into contact
with clothing. If there is contact with the
fluid , flush immediately with plenty of
wa­
ter.

Ch eck ing and Filling
Catalytic converter
Applies to: vehicles with gasoline engine
It is very important that your emission control
system (cataly tic converter) is functioning prop­
erly to ensure that your vehicle is running in an
environmentally sound manner.
.,. Always use lead-free gasoline c:> page 190 , Fuel
supply.
.,. Never run the tank down all the way to empty .
.,. Never put too much motor o il in your engine
c:> page 203, Adding engine oil.
.,. Never try to push- or tow-start your vehicle.
The catalytic co nverter is an efficient "clean -up"
device built into the exhaust system of the ve hi­
cle. The catalyt ic converter b urns many of the
po llutants in the exhaust gas before they are re­
leased into the atmosphere.
The exclusive use of un leaded fuel is cr itically im­
portant for the life of the catalytic converte r and
prope r funct ion ing of the eng ine .
_&. WARNING
The tempera ture of t he exhaus t sys tem is
h igh, bot h when driv ing and a fter stopping
the engine .
- Never tou ch the exhaust tail pipes once they
have become hot. This cou ld resu lt in burns.
- Do not park or operate the vehicle in ar eas
where the hot exhaus t sys tem may come in
contact with dry grass, b rush, fuel spill or
other material which can ca use a fire.
- Do not app ly additiona l undercoating or
r u stp roofing on or near the exhaust mani­
fold, exha ust pipes, cata lytic converter or
heat shields . D uring driving, the substance
used for undercoat ing could overheat and
cause a fire.
CD Note
- Be aware that just one tank fi lling with
leaded fuel w ill already seriously degrade
the performance of the catalytic converter .
- Do not exceed the correct engine oil leve l
