Your vehicle needs AdBlue® to reduce NOₓ emission. Due to the stricter emission legislation, diesel engines need to have cleaner exhaust gases. NOₓ is one of the emissions that causes acid rain. To meet the Euro 6 standards for diesel engine emission the use of Selective Catalyst Reduction-technology (and thus AdBlue®) is required. The Euro 6 standards are into force from September 2014 for new passenger cars.
All commercial vehicle manufacturers have to meet the Euro 6 standards for diesel engine emission. Although Euro 5 emission standards could be met by different technologies, Euro 6 standards require the use of Selective Catalytic Reduction with AdBlue®.
