Thanks to BMW BluePerformance technology, it is possible to further optimise the emissions response of diesel engines. In addition to the diesel particulate filter and oxidation catalytic converter, there is also a NOx catalyst storage which further reduces the level of nitrogen oxide in the exhaust gas. The combustion process itself is not affected and the diesel engines’ high degree of efficiency is preserved.
With some models, an additional method of nitrogen oxide reduction is used: the SCR catalytic converter (SCR = Selective Catalytic Reduction) with AdBlue® injection. A chemical reaction triggered by injecting the AdBlue® solution greatly reduces nitrogen oxide emissions.
This enables the diesel models to already meet the requirements of the EU6 emission norm that comes into effect in 2014. You can refill the AdBlue® solution yourself or can arrange an appointment with your BMW Service Partner.
Your diesel engine must be regularly refilled with AdBlue® fluid to function smoothly. You can simply fill the AdBlue® tank yourself.
If needed your BMW Service Partner will be more than happy to help.
An overview of the main facts:
– From 2,400 km the remaining range is shown in the Control Display. You can also have the current remaining range and refill quantity displayed at any time
(Vehicle information > Vehicle status > AdBlue).
– The maximum range of a tank of AdBlue® will depend on your personal driving style and is usually approximately 15,000 km.
– A refill of AdBlue® fluid is required as soon as the reserve display appears on the instrument panel. Please refill the fluid yourself or contact your BMW Service Partner and arrange a refill appointment.
– The AdBlue® filler neck is to be found underneath the fuel filler flap or in the engine compartment, depending on the BMW diesel model.
Important: Remember to refill AdBlue® in time. If the tank is empty, the automobile cannot be restarted after parking.
