I’m looking to buy a new van due to the clean air zone that’s been introduced where I live and am considering a Doblo XL 1.6L. Someone told me that diesel particulate filters on vehicles with multijet engines are less likely to block than with other vans. And I wondered if anyone else is able to confirm this? I do mainly short trips in the city centre where I live, and petrol vans aren’t an option as the ones on the market don’t provide enough cargo space for me. My knowledge of mechanics is zero so I’d really appreciate any advice !
