Thanks to BMW BluePerformance technology, the emissions response of this diesel engine has been further optimised and the level of nitrogen oxide in the exhaust gas has been further reduced. 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 further 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.
Further information on the uncomplicated refilling process can be found in the BMW BluePerformance brochure.
