Hello,
I've got an emissions issue with my 60 plate, 1.6 multijet Doblo, and I'm hoping the extensive knowledge base on here can help me sort it out.
I bought the van with an MOT from a dealer in 2019, and its since gone through 6 MOT's at 2 depots without any emissions issues. This time - first time at a third depot, it has failed on emissions big time. Van is running fine with no noticeable smoke issue.
The repair garage have replaced the fuel filter and flushed through the diesel system, but this has apparently only made a small difference to the readings. Garage have said the problem could be anything, and it could soon be economically unviable to repair.
They also asked if the engine had been replaced or if I had removed the DPF, as it is not in place. I do work on my vehicle, but haven't touched either of those items - indeed, if it wasn't for this issue arising, I would have been none the wiser as to what a DPF is (or was in van 's case!).
Upon research, I see that it is an offence to remove such an item, and it is also an MOT failure to not have a DPF if one should be fitted. Looking at the engine briefly, I can see a small bore metal pipe coming from the area of the block, that looks like it should be connected to something.
So, I'm wondering several things.....
1/ Should my vehicle have a DPF, and where do I go to find out whether it should or not?
2/ If it should have one, is it feasible to retro fit one?
3/ Is the lack of a DPF likely to cause very high emissions readings?
