Mercedes-Benz has halted sales of its E 350d in Germany. The decision was delivered after confirming its intentions to re-engineer the turbocharged 3.0-litre V6 diesel model’s exhaust gas after-treatment system as part of a recertification process. The new E 350d went on sale in the Germany in May, 2017 in both saloon and estate body types following the re-manufacturing of the former model’s exhaust gas after-treatment system. The German brand now rights to have identified more changes required to its OM642 LS motor that will allow it to claim lower NOx emissions. The changes to be made to the E 350d include fitting a larger SCR catalyst. Adopting a larger SCR catalyst will provide a larger surface area for the atomization of the AdBlue solution, which will increase its ability to neutralize NOx emissions. Mercedes has denied the allegations that it has been forced to fit a larger
AdBlue tank to the diesel E350d as part of the changes.

The recertified system is claimed to use the same amount of AdBlue solution with each injection of fuel, ensuring it will not be emptied between servicing intervals. “It is the larger surface area of the new substance that is key to the proficiency gains,” The E 350d uses a 24.5-litre AdBlue tank, while larger models like the GLE 350d and GLS 350d have a 38.5-litre tank. Mercedes won’t confirm when the E 350d will go on sale again, but says the recertification should take “a little weeks”. Mercedes-Benz sells the long wheelbase version of the E-class in India with three engine options – the 184hp, E 200 petrol, the 194hp, E 220d diesel and the same 258hp 3.0-litre V6 in the E 350d. There is no word on the manufacturer suspending sales of the India-spec E 350d.
