- Vito 116cdi, 2011 R Class 350cdi 4matic, Mitsubishi Outlander, Viano 2.2
So, a while back my Viano started to smell diesely and one of the injectors was blowing by, so I decided to have all replaced as the mileage is 327000, it ran much better, smoother pickup and more power plus better mpg, well worth it then? Well, maybe not as it has just failed mot on high emissions, not that they are really high but the plate figure is really low at 0.1 compared to the R class which is 0.5 all this assuming I am looking in the right place, so if the plate value isn't there or can't be found the limit for my age of car is 1.5 and mine is coming in at 0.4, but due to the plate value being 0.1 it has failed.
The MOT station say put a new dpf, without any diagnostic work this seems a bit dodgy, so I am doing what should be done, taking it to Mercedes for a diagnostic, there are no fault codes and the lambda reading appears ok so what could the issue be, does it just need a good thrash or has the garage that fitted the injectors not put the codes in correctly, it runs great so i doubt it would make any difference with the closed loop control, could it be the dpf, if so what is wrong with it, the usual issue is that they block up but there's no evidence of that and it does get some good runs.
Anyone had experiences similar to this? what was the final outcome?
