Passenger cars and Light Commercial Vehicles (LCV)

Since 2016, in order to comply with the latest emissions legislation AdBlue® has been required for most new diesel powered passenger cars, vans and other light-duty vehicles.

Referred to as Selective Catalytic Reduction (SCR) technology, you will have to fill check the level of AdBlue® and fill your vehicle as when required. In addition to direct supply, our packaged AdBlue® is available in a variety of sizes to suit all needs, which are available via Fuel companies, Car & LCV manufacturers, franchises, retailers, workshops and motor factors.

How does the system work?

AdBlue® is a synthetic urea based solution, which is stored in a separate tank and injected directly into a specially modified part of the vehicle’s exhaust system. This begins a chemical reaction which removes the polluting nitrogen oxides (NOx), converting them into harmless water and nitrogen in a process known as Selective Catalytic Reduction (SCR)

SCR is only applicable to diesel engines. The frequency of tops up may vary due to the size of the AdBlue® tank fitted to your car, journey mileage, journey type and driving style. A passenger car can consume approximately 1 litre of AdBlue® every 500 miles.

How will I know if the system needs topping-up?

A series of warnings will be given, accompanied by advice/messages via the driver information system.

If these warnings are not acted upon the car will not restart once the ignition is turned off. The system will need a full top-up before the car can be restarted. This is not a fault, but a required feature of the system.
