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 ⇒ Refilling AdBlue. If you ignore the last refill reminder, it is impossible to
start the engine again after it is switched off ⇒ Warning and indicator lights.
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 b and > both come on together, there is a malfunction. Volkswagen recommends that you take the vehicle to the closest qualified workshop.
