How does the AdBlue® system work on BMW models?
BMW diesel models meet the Euro VI standard, which imposes limits on nitrogen oxide emissions for diesel models sold since September 2015. Therefore, in addition to a particulate filter, BMW equips some of its diesel engines with SCR (Selective Catalytic Reduction) technology—known as BMW Blue Performance—in order to reduce emissions generated by fuel combustion. This technology uses AdBlue®, which it injects into the engine to convert the harmful nitrogen oxide emissions produced by diesel vehicles into water and nitrogen. Some BMW diesel vehicles do not need AdBlue® to meet the Euro VI standard.
How does the warning system work on a BMW?
The warning system simply lets you know that you need to top up your tank. When your remaining range is 1440 miles (2400 km), a warning will appear on your car’s display. You can check your remaining range at any time using the “Vehicle information > Vehicle status > AdBlue®” function. As soon as the warning light comes on, you will need to go to a filling station to refill your tank. Warnings will gradually decrease until your tank is completely empty, at which point it will no longer be possible to restart your car.
How do you fill up a BMW with AdBlue®?
The capacity of AdBlue® BMW tanks is either 12 l or 15 l. The filler neck is located either in the fuel-filler flap next to the diesel tank filler flap or in the engine compartment. Refer to the different vehicle specifications for the various models to find specific information on your vehicle model.
