AdBlue

You may be asking ‘what’s AdBlue and why do I need it?” AdBlue is a special liquid that’s sprayed into diesel car exhausts to reduce the amount of harmful gases released into the environment by diesel engines. Your AdBlue is typically topped up as part of a service, with many drivers unaware it’s even there. If your AdBlue warning light comes on, then you’ll need to top it up quickly, or your vehicle may enter limp-home mode or even stop working at all.
