Diesel Exhaust Fluid testing

In an big effort to reduce environmental pollution, the European Union has established certain rules about emissions from heavy and light goods vehicles. One method adopted by vehicle manufacturers to allow compliance is SCR (Selective Catalytic Reduction), which chemically reduces NOx-emissions using a urea additive, known as AdBlue® within Europe (or DEF in the USA) in to the exhaust flow.
