Mercedes Facing New Dieselgate Nightmare

For the record, the devices are not on a currently-produced E-Class. The report – commissioned by US law firm Milberg and carried out by automotive software expert Felix Domke – claims that a 2016 E 350d with the OM642 engine has six defeat devices connected to the car’s SCR catalytic converter and another two for the car’s exhaust gas recirculation system. The DUH deems these devices illegal and says that they are used to misstate emissions results during laboratory testing. In the real world, the engine produces as much as 500% more in nitrogen oxide emissions than the legal limit allows. Domke goes on to say that one of these devices “significantly reduces the amount of AdBlue injected, which is urgently needed to neutralize the nitrogen oxides in the SCR catalytic converter.”
