AdBlue® [*AdBlue® is a registered trademark of the Verband der Deutschen Automobilindustrie e. V. (VDA)] improves your "green" credentials on the road. The most important reasons for this, which models use AdBlue® and how to top up AdBlue® are provided here in black and white.
AdBlue® is an odourless urea solution, whose task is to reduce harmful nitrogen oxides
in the exhaust gases of diesel vehicles. A complex reaction, which proceeds completely unnoticed by you as a driver. All you have to do is simply top up AdBlue®
after several thousand kilometres.
Volkswagen models with AdBlue®.
How do you recognise AdBlue® models apart from their lower emissions of nitrogen oxide?
By a separate AdBlue® filler neck – in addition to the diesel filler neck,
in the boot or engine compartment. Why? AdBlue® is an operating fluid,
not a fuel additive and must be added separately.
