Your car is not taken away and the filter will not budge. A fitter arrives at your place over in Seavington St Mary, cleans the diesel particulate filter fitted to the vehicle and runs a DPF regeneration. Nobody sets off until the price is fixed on the phone. The visit runs typically around 2 hours and the clean begins from £299. If the light is showing and the vehicle is down on power, this page is yours. That is how most owners arrive here. ## What to check when the DPF light comes on The filter is not always what is to blame, and that goes first. A clean is not where a visit opens. A diagnostic is — a number of faults register as the same light. It matters what you do with the motor between now and the visit. - Worth a shot before you book anything: amber light, vehicle driving as normal, just one steady run, no outlay. - That window has shut once the motor has dropped into limp mode. A drive will not get there now. - Stop planning long drives and get it looked at if the cabin reeks of diesel or there is black smoke when you accelerate. ## What the car has been warning you The light is last news. By the time it shows, the symptoms have usually been building for weeks: - power tailing off, particularly climbing uphill - you see the revs fall short of where they once went - worse fuel economy - quietly, the stop/start bows out - diesel in the interior, or smoke on the way up through the gearbox Any one of those, taken by itself, is not proof. Next to the light, it is a fair bet the filter is blocked. ## What clogs diesel particulate filters around Seavington St Mary For a DPF, the least kind driving is the kind you get in a rural village such as Seavington St Mary. The school run to Shepton Beauchamp Church School, Scotts Hill at a crawl at half eight, five minutes to Tesco, the hop to Crewkerne — none of it runs long enough or is hot enough for the filter to finish a regeneration. Soot that should clear banks up instead. Neither is far from Seavington St Mary: under 15 miles to the M5, under 25 miles to Wells. Neither is on the way to anywhere most weeks, though, so the drive that would scour a filter never gets made. ## The moment a DPF regeneration can no longer complete What limp mode comes down to is the vehicle looking after itself. Pulling power is held down, the revs will not pull, and the regeneration the filter needs can no longer complete — which is the real catch, because a long drive works by triggering that regeneration. The common advice — get it up the motorway — is sensible, up until it is not. The far side of that line — limp mode — road work will not do it, and the filter needs cleaning. ## The motor stays put for on-site DPF cleaning in Seavington St Mary On your drive, in a work car park, wherever the motor can stand for a couple of hours: the job takes place with the filter still fixed on, which is the bit most owners do not expect. The ECU is read first, reporting soot load by proportion and by actual weight, along with a look over of sensor feeds, glow plugs and connected components, so nothing is started while another fault is still open. Soot and ash that a regeneration alone will never shift are loosened second, by a solution fed through the access port on that motor, which expands inside the filter. Badly blocked filters sometimes require a second pass. Next, a regeneration drives off everything the clean lifted. Stay with the vehicle and it turns into a monitored drive out of Seavington St Mary. Park it and the regeneration goes in place, with running data verified once it is done. Then a second check, confirming the change, resetting the warning light and noting anything still showing. Both read-outs are sent over, so the before and after figures are recorded. ## The failures a DPF clean cannot fix A filter choked with soot and ash is the one thing a clean answers. It will not reach: - the wrong signal from a temperature or pressure sensor - an EGR valve jammed open - an AdBlue system problem - glow plugs or injectors blocking the regeneration starting in the first place - a turbo passing oil through the filter Finding that out is the first check's whole job. Where it proves to be one of those, you are told before any work gets going rather than after you have settled up anything. Lastly, two things. A vehicle with the filter cut out cannot pass its MOT, and driving it is against the law, so that is no fix. What gets looked up as DPF renewal exchanges nothing: your existing filter is cleaned in place and goes back into work. ## The figure for DPF cleaning across Seavington St Mary Any visit carries a call-out charge — getting to you, taking the booking, doing the check and giving the advice. The clean itself starts from £299. Once we are told what you drive, and about what the filter will take, the price gets fixed on the phone. A single price for everyone would not be straight. What you drive and where you are both shift it: Seavington St Mary itself, out at Whitelackington, or farther out across the TA postcode area. Where the scan says a clean will not work, you are not asked to pay for cleaning. Because the visit, the check and the advice have been done, the call-out charge even so stands. A 30-day warranty takes in aftercare on the clean, and that includes an engineer coming back out to Seavington St Mary if the light comes back inside the period. ## Where we get to round Seavington St Mary, and what we clean Cars, panel vans and light commercials, HGVs, plant machinery, farm vehicles — one mobile service across all of them, and on all of them the filter is treated on the vehicle rather than taken anywhere. Technicians are along Scotts Hill most weeks, so Seavington St Mary is hardly ever a special trip, and the same run picks up Whitelackington, Dinnington and the places out past Seavington St Michael. Further out around Somerset is still worth ringing about — coverage reaches UK-wide, and it is the calendar rather than the distance that decides between one day and the next. ## The patch around Seavington St Mary Seavington St Mary is a small village in inland Somerset, situated near the villages of Seavington St Michael and Allowenshay. Seavington St Mary lies at an elevation of 53 metres, approximately 21 miles from the city of Wells.

If you spot it in time, and the vehicle is not in limp mode, sometimes. That means motorway speed for a steady run, rather than a short trip to Tesco. Broadly how long does it last? It is typically around 2 hours. A severely clogged filter can require a second clean, which adds to that. Around Seavington St Mary, what does it come to? Treatment begins from £299, and the call-out charge on top covers the visit, the check and the advice. Settling it is done by phone, since what you run and where you live both shift the price. Is it necessary for me to be present? No. The car needs somewhere to sit for a couple of hours; you do not need to stand with it. The regeneration can be run as a watched drive if you would sooner ride along. Coming to Seavington St Mary — how soon? Depending on the calendar, often same-day or next-day is usual. Phone 0303 330 1830 and you will know what is open across the TA area. Is the filter taken off the car? It is done where it sits, on the call-out service. We do not lift filters off or bolt them back on, either way. The light reappears — then what?
