What is AdBlue?
AdBlue is an exhaust fluid in DIESEL VEHICLES, not a fuel additive. It is stored in a separate reservoir and is topped up via a (usually) blue filler cap located either next to your fuel filler, in the boot or under the bonnet.
What happens if I run out of AdBlue?
If you run out of AdBlue while driving, then the engine’s performance will be reduced to limit its emissions. Once stopped, you will not be able to restart the engine if the AdBlue tank is empty.
The car will give you plenty of warning that the AdBlue tank’s running low. You will usually see a text warning on the dashboard at around 1500 miles to go followed by an amber warning light.
Which vehicles use AdBlue?
Not all car manufacturers use AdBlue technology. But it is very likely that if you have got diesel from Jaguar, Land Rover or any French or German manufacturer, new from 2015, it will use AdBlue.
