Diesel particulate filters (DPF) operate in a similar way, but as the temperature of a diesel vehicle's exhaust gas is lower than that of a petrol car, the DPF 'burn off' may need to occur DPFs are legally mandated on all diesel-powered road vehicles and must be kept in good working order to keep your vehicle running smoothly in accordance with the law. Failure to maintain a DPF filter can result in serious mechanical issues for your vehicle, never mind the repercussions if a police officer stops you. Our Gen 3 was diesel and we have a mix of months with fairly short journeys mixed with weeks of long distance driving and have never had any dpf issues, even with other makes of car, Renault, Citroen. It sounds a more deep seated problem than just the dpf, as it re-occurred after they changed the filter. An E.P.A. investigation has found that the owners of more than half a million diesel pickup trucks have installed devices to defeat emissions controls and boost pollution. Re: Are BS6 diesel cars with DPF suitable for primarily town/city usage (DPF–diesel particulate filt Given your usage pattern, I would strongly recommend a petrol. A diesel would inevitably give problems unless you are able to run at over 60 kmph for 15-20 minutes at a stretch regularly, which I presume is not possible with your usage pattern. Hi. We have an Urban Cruiser, and in a lot of ways its the perfect runaround car! Small, spacious, AWD, frugal, modern, safe, reliable, 5 doors, comfy, good ground clearance (we live in the countryside), lots of ticks! DPF- Argh! Had it cleaned 3 months ago by a DPF specialist at a cost of £300, DjSNI. Now making up around 50% of all new cars sold, diesel cars have risen in popularity, particularly because of their fuel economy and lower running costs. To reduce emissions, diesel cars are fitted with a diesel particulate filter (DPF) – something that filters and catches soot particles. Most DPFs will automatically clear as they’re used One of these systems is the Diesel Particulate Filter (DPF) which sits in the exhaust system and filters harmful carbon particulates produced in the combustion cycle, preventing these particles from being released into the atmosphere. First fitted to diesel vehicles from 2007, the DPF has been causing confusion and, in many cases, expensive Inadequately maintained particulate filters on vehicles with diesel engines are prone to soot buildup, which can cause engine problems due to high back pressure. In 2018 the UK made changes to its MOT test requirements, including tougher scrutiny of diesel cars. One requirement was to have a properly fitted and working DPF. Not many drivers know what a Diesel Particulate filter (DPF) is – until it costs them serious money. And replacing one can cost £1000 or more. Green Flag attends a lot of cars that have broken down with DPF problems and they are caused by one primary factor: the DPF is clogged with soot because the driver has ignored the warning lamp.

As long as the engine reaches 2000rpm for 15 minutes on a regular basis then the DPF won't clog up and need to go through a regeneration cycle.
