Selective catalytic reduction (Ad Blue)
General information
Applies to: vehicles with selective catalytic reduction (SCR)
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 1.2% of the diesel fuel that is
used.
When a message about Ad Blue appears in the in­
strument cluster display, you must refill the
Ad Blue yourself or have it refilled by an author­ ized Audi dealer or author ized Audi Service Facili­
ty
¢ page 217.
@ Tips
-The instrument cluster display indicates the
distance remaining that can be driven
¢page 216. If the AdBlue tank is com­
pletely empty , the eng ine will not start
again after the ign ition is switched off.
- Ad Blue is required by law to operate th is ve­
hicle.
