I just bought a 2011, 2 litre diesel Toyota Verso to use for journeys of approximately 50 miles round trip and needing a low loading area for my parents mobility scooter. I use my wife's petrol Yaris for town driving. I believe the Verso has chain cam engine but also a PDF and DMF. How long and at what revs should it be driven for to clean the PDF. If I do use it for short journeys, how often does it need a longer ride to clear the PDF?

You mean a DPF (diesel particulate filter). Your 50 mile round trips should be enough to promote regeneration when needed. If you use it for repeated short runs from cold starts when the engine never gets fully to temperature, then the PDF is likely to get clogged with smuts. There is a chance that running it for 50 miles or so at more than 2,000rpm will then clear it.

Is there a diesel car yet that can cope with town driving/short journeys without clogging the diesel particulate filter (DPF) and exhaust gas recirculation (EGR) components?
I am looking to buy a medium sized diesel without DPF. After reading too many internet forums I am now unable to decide what to plump for given that there seems to be so many diesels that have expensive...
I have just acquired a Citroen C8 and a warning came up on the panel that the diesel additive needed attention, and to get a local dealer to look at it.
