No body shop, no filter leaving. A fitter drives out to your address over in Cheldon, clears the diesel particulate filter in place, carries out a DPF regeneration, and you end up with the filter you started with. Nobody travels until the price is settled by the phone. The visit takes typically around 2 hours and the clean starts from £299. Most owners find us with the light already on, and the vehicle short of power. That is the situation this page is aimed at. ## The DPF light is on. What then? First thing: it is not necessarily the unit. That light can follow several faults, not just one, so the visit starts with a check and not with treatment. Second thing: how you run it between now and then matters. - A long constant run may still be enough, provided the light is amber and the motor runs as normal. Costs nothing at all, so have a go at that before calling. - A drive will not reach it now — limp mode means that window has already closed. - Stop planning long drives and get it seen to if the interior stinks of diesel or there is black smoke when you press on. ## The car has been telling you already The light is belated news. By the time it appears, the symptoms have generally been growing for weeks: - pulling uphill, the power tails off - revs that will not rise the way they used to - the fuel consumption is poorer - the stop/start silently bowing out - smoke under acceleration, or a diesel smell in the car That is not proof by itself. Next to the light beside them, the filter is a fair guess. ## Why diesel particulate filters clog round Cheldon Cheldon is a small village, and the motoring that goes with one is the poorest kind for a DPF. The school run to East Worlington Primary School, West Burridge Cross at a crawl at half past eight, five minutes to Sainsbury's, the run to Lapford — not one bit of it goes on long enough or gets hot enough for the filter to complete a regeneration. The soot load banks up rather than burning away. Neither is far from Cheldon: under 25 miles to the M5, under 25 miles to Exeter. Neither is on the way to anywhere most weeks, though, so the journey that would scour a filter never comes. ## Limp mode, and when DPF regeneration stops working The vehicle is defending itself, which is what limp mode is. With output limited and the revs kept low, the regeneration the filter requires can never complete at all. That counts, because starting one is just what a motorway run does. The standard advice — take it up the motorway — is sensible, up until it is not. Beyond that stage — limp mode — more driving will not manage it, and the filter wants a clean. ## DPF cleaning at the car in Cheldon On your front, in a work car park, any place the car can wait for a couple of hours: the job happens with the filter even now fitted on, which is the bit most drivers do not see coming. A diagnostic happens first — real-time data off the ECU, soot load by percentage and by mass, and a check of the sensor readings, glow plugs and related components, so other faults are cleared before anything is started. Soot and ash that a regeneration by itself will never shift are freed next, by a cleaning solution put through the access port on that car, which opens out inside the filter. Where the filter is badly loaded, allow for a second pass. A regeneration comes next, clearing what the clean has lifted. Either it goes as a monitored drive out of Cheldon, with you along, or it runs where the motor waits and the real-time data is verified afterwards. Then a second scan, verifying the change, putting out the warning light and listing anything still logged. Both reports are emailed, so the before and after figures are on record. ## What a DPF clean will not fix Treatment answers one thing: a filter clogged with soot and ash. It does little for: - sensors, pressure, reporting a restriction that is not real - an EGR valve stuck open - an AdBlue system fault - a regeneration that never starts, because of glow plugs or injectors - oil coming through the filter from a failing turbo The first scan is there for just that. Where one of those is the fault, you find out about it at the outset rather than once the money has gone already. Lastly, two things. A vehicle with the filter hollowed out cannot pass its MOT, and driving it is against the law, so that is no remedy. What gets typed in as DPF renewal exchanges nothing: your existing filter is treated in place and goes back into work. ## What DPF cleaning runs to around Cheldon A call-out charge stands whatever follows, and takes in the visit, the booking fee, the diagnostic and the advice passed on. Cleaning itself opens from £299. Quoting a flat rate would not be truthful. We agree it on the phone, once the car and its probable needs are clear. The vehicle moves it, and so does the address — Cheldon, Chawleigh, or a spot otherwise out in the EX postcode area. Where the check says a clean will not work, you are not billed for a clean. The call-out charge still holds, because the visit, the scan and the advice have taken place. The job includes a 30-day warranty taking in aftercare, including an engineer coming back out to Cheldon if the light comes back inside that window. ## Vehicles we clean, and where we travel round Cheldon Cars, vans and light commercials, HGVs and lorries, plant machinery, agricultural vehicles — the one call-out service across all of them, and on all of them the filter is done on the vehicle rather than moved anywhere. The same round that has technicians on West Burridge Cross most weeks picks up Cheldon, Chawleigh, Week and the villages beyond Chulmleigh. It is the diary, not the distance, that settles whether it is this day or the next, and coverage extends UK-wide — so ring still from farther out through Devon. ## The ground around Cheldon Cheldon is a small locality in Devon, situated on the riverside at an elevation of 156 metres, with detached housing being the predominant type of accommodation. Cheldon lies near the villages of Chawleigh, Filleigh, and Week, and is approximately 17 miles from the city of Exeter. Cheldon is a relatively small community, with a population of around 347 people. Cheldon is located in the South West region of England, about 164 miles from London. ## Things Cheldon drivers ask about DPF cleaning Can I simply take it for a long drive? It might, provided you get it early enough and limp mode has not arrived. A steady run at motorway speed is what it wants — not five minutes or so to Sainsbury's and back. How long does the visit take? Bank on typically around 2 hours, with a second clean extending that where the filter is severely blocked. In Cheldon, what does it come to? It begins from £299, plus the call-out charge covering the visit, the diagnostic and the advice. We quote on the phone, because the vehicle and your address both move the number. Is it needed for me to be present? No. The motor needs space to wait for a couple of hours; nobody expects you to stand with it. If you would sooner come along, the regeneration can be carried out as a watched drive instead. How soon can someone get to Cheldon? That comes down to the calendar, but it is often same-day or next-day. Ring 0303 330 1830 and we will let you what is available across the EX area. Does the filter come off the car? On the call-out service, no: the filter is done in place. Nor does getting a filter off nor bolting one back on is work we do. What if the light returns? Included by the 30-day warranty: aftercare, and an engineer heading back to Cheldon. ## Book a DPF clean in Cheldon Ring 0303 330 1830 and talk us through what the vehicle is doing: a light, limp mode, smoke, whatever it is.
