How to Refill AdBlue

Model: (Various brands) Various
Part: AdBlue warning light

Video tutorial

In this video, you will learn how to refill AdBlue (or urea, if you prefer the non-commercial name of the additive). The five-litre containers available in shops have a special nozzle designed to access the tank.

Position it over the opening of the container and use this nozzle to locate the additive cap: On most vehicles, it is next to the diesel cap, but some have it inside the boot, even under the spare wheel (making it less accessible). Taking care not to spill it, pour the additive into the tank.

Remember that keeping the tank nearly full is the best way to avoid crystallisation of the additive in the tank. Replace the cap, and the operation is complete.
