In vehicles with selective catalytic reduction, a special urea solution (AdBlue) is injected into the
exhaust system ahead of the catalytic converter in order to reduce nitrogen oxide emissions.
AdBlue is stored in a separate tank of the vehicle and should be refilled under normal driving
conditions during service according to the maintenance schedule. The AdBlue tank holds slightly less
than 5 gallons (20 liters).
AdBlue consumption depends on the individual driving style, system operating temperature, and
outside air temperature. Therefore in rare cases AdBlue may have to be refilled between service
events.
Starting with a remaining range of about 1500 miles (2400 km), a reminder to refill AdBlue is displayed
in the instrument cluster. If you ignore the last refill reminder, it is impossible to start the engine again
after it is switched off
Volkswagen recommends that you have the AdBlue tank refilled by an authorized Volkswagen dealer
or an authorized Volkswagen Service Facility. If no authorized Volkswagen dealer or authorized
Volkswagen Service Facility or other qualified workshop is available, you should refill at least 1.5
gallons (5.7 liters) of AdBlue (3 AdBlue bottles). Refill only the type of AdBlue that Volkswagen has
explicitly approved for your vehicle.
If warning lights ~ and d both come on together, there is a malfunction. Volkswagen recommends that
you take the vehicle to the closest qualified workshop.
