Euro 6, diesel engines and selective catalytic reduction: What is DEF, how to refill and FAQs
Diesel Exhaust Fluid (DEF) also known as AdBlue™, is a non-toxic, colourless, odourless and non-flammable fluid. Stored in a dedicated tank in your car, it is injected into the exhaust system to clean exhaust gases. Selective Catalytic Reduction (SCR) technology is fitted to all Land Rover diesel vehicles from 2016 Model Year. It enables Land Rover to meet EU6 emissions legislation by reducing the levels of nitrogen oxide (NOx) emitted from the exhaust system by up to 90%. In addition to a new generation of catalytic converter, SCR Technology requires the use of DEF.
The message centre displays a series of messages when the DEF level becomes low.
It is important that your Land Rover’ supply of DEF is maintained, as EU legislation means that you cannot start the engine without it. Your car’s message centre will give you advance warning when your DEF level is low and will alert you in plenty of time to book a refill.

Euro 6 is a piece of European Legislation aimed at making cars more environmentally friendly by limiting their exhaust emissions. The legislation sets restrictions on how much nitrogen oxide (NOx) and hydrocarbon gases may be emitted per kilometre by a road vehicle.
Petrol and diesel cars are subject to different restrictions under the new Euro 6 legislation. For diesel cars, the permitted level of NOx emissions has been brought down to 80 mg/km (from 180 mg/km), while the permitted level of hydrocarbons emissions has been brought down to 170 mg/km (from 230 mg/km). The permitted level of NOx emissions for petrol cars remains at 60 mg/km, while the permitted level of hydrocarbons emissions remains at 100 mg/km.
Along with other car manufacturers, Land Rover is legally obligated to comply with these new regulations by the following dates:
From 1st January 2015, all newly introduced vehicles must meet Euro 6 standards. This includes any new models on the market, for example: Discovery Sport. Vehicles already on sale must comply with Euro 6 by 1st September 2015, but;
Individual vehicles already on sale that were built by, and dispatched from, the manufacturer before 1st June 2015 can continue to be sold until 1st September 2016. However, the manufacturer must apply for derogation in these instances.
For more information on AdBlue® please contact your local Land Rover Retailer or refer to your Owner’s Handbook.
