AdBlue E-Class W212

thingiverse

E-Class W212 owners rely on efficient diesel engine performance, which is made possible by an effective Exhaust Gas Recirculation (EGR) system and Selective Catalytic Reduction (SCR). To maintain this performance, periodic AdBlue injections are necessary. The process involves introducing a specialized liquid, also known as Diesel Exhaust Fluid (DEF), into the exhaust stream where it reacts with harmful nitrogen oxides to create harmless nitrogen gas and water vapor.
