Selective catalytic reduction
General information
Applies to vehicles: with selective catalytic reduction
In vehicles with selective catalytic reduction, a
urea solution (AdBlue) is injected into the ex­
haust system before a nitrogen oxide catalytic
converter to reduce nitrogen emissions.
The Ad Blue is carried in a separate tank in the ve ­
hicle. The AdBlue usage accounts for approxi­
mately 0.5% to 2.5% of the diesel fuel that is
used.
When a message about refilling the AdBlue ap­
pears in the instrument cluster display, you must
refill the Ad Blue yourself or have it refilled by an
authorized Audi dealer or authorized Audi Service
Facility
r:!.>page 213 .
{!) Tips
-The instrument cluster display ind icates the
distance remaining that can be driven
¢ page 213. If the AdBlue tank is com­
pletely empty, the engine will not start
again after the ign ition is switched off.
- Ad Blue is required by law to operate th is ve­
hicle.

CJ) Note
-Only use Ad Blue that conforms to the
standard ISO 22241-1. Do not mix any addi­
tives with the AdBlue and do not dilute it
with water.
- Do not add Ad Blue to the diesel tank or add diesel fuel to the AdBlue tank. Mixing can
lead to damage to the engine and the Ad Bl­
ue tank system .
- AdBlue attacks surfaces such as painted ve­
hicle components, plastic and carpet. Re­
move the fluid as quickly as poss ible with a
damp cloth and plenty of cold water . If the
Ad Blue has already crysta llized, use warm
water and a sponge. Ad Blue residue that is
not removed will crysta llize and can damage
the affected surface.
- Do not store refill bott les or canisters per­
manently in the vehicle. If the container
l eaks, the escaping AdBlue could damage
the vehicle interior.
- Do not allow Ad Blue to come into contact
with clothing. If there is contact with the
fluid, flush immediately with plenty of wa­
ter.
