The engineer arrives at your door over in Longbridge and gets to work. The diesel particulate filter is treated fitted to the car, a DPF regeneration runs after it, and you end up with the filter you arrived with. You'll have a number by phone before anyone departs, the clean starting from £299, and the visit lasting typically around 2 hours. The light is already on and the vehicle is short of power — that is how we normally meet people, and what this page covers. ## Your DPF light is lit — what then? The unit is not automatically what is at fault, and that leads. That light can follow a number of faults, not merely one, so the visit begins with a diagnostic and not with a clean. Second thing: how you drive it between now and then counts. - Worth a try before you ring anything: amber light, motor driving as normal, just one even run, no cost. - Vehicle already fallen into limp mode — that window has shut. A drive will not reach it now. - Diesel smell in the car, or black smoke under acceleration — stop booking long drives and get it seen to. ## Before the light, what the car was telling you Last news, the light. The symptoms tend to mount for weeks before it arrives: - going uphill, the power tails off - revs that will not climb the way they used to - consumption that is worse than before - without a word, the stop/start gives up - a diesel smell in the interior, or smoke under hard acceleration None of that is conclusive alone. The light with them suggests a blocked filter. ## The explanation diesel particulate filters block round Longbridge For a DPF, the poorest driving is the sort you meet around a residential suburb such as Longbridge. The school run to Woodford Primary School, St Modwen Road at a crawl at half eight, ten minutes to The Food Warehouse, the run to Plymouth — none of it lasts long enough or is hot enough for the filter to finish a regeneration. The soot that should burn off banks up instead. Geography does not help either. The M5 is under 50 miles from Longbridge and Plymouth is under 3 miles away, so unless something carries you out that way often, weeks go by without the long steady run that might scour the filter by itself. ## DPF regeneration, and the point limp mode ends it What limp mode comes down to is the vehicle looking after itself. With output limited and the revs kept low, the regeneration the filter wants can never run at all. That counts, because setting off one is just what a long run does. So the common advice to get it up the motorway is sensible advice, until the day it is not. Past that stage — limp mode — more driving will not do it, and the filter wants a clean. ## The motor stays where it is for on-site DPF cleaning round Longbridge Nothing leaves the vehicle. That catches out people. The DPF stays fixed where it is and the work is done around it, on a forecourt, in a works car park, anywhere it can wait for a few hours. Nothing is touched until other faults are cleared. That requires a diagnostic first: real-time data off the ECU, soot load by percentage and by weight, and a look over of the sensor feeds, glow plugs and connected hardware. Soot and ash that a regeneration by itself will never move are freed after that, by a solution fed through the access point on that car, which spreads inside the filter. Sometimes a filter is blocked enough to need doing twice. Next, a regeneration drives off everything the clean freed. Ride along with the motor and it is done as a monitored drive out of Longbridge. Leave it and the regeneration runs statically, with running data verified once it is done. A second scan proves the change, puts out the warning light and notes anything still open. Both read-outs are emailed over, so you end up with the before and after figures to hand. ## When a DPF clean is not the solution Only one fault is answered by cleaning: the filter clogged with ash and soot. It does nothing for: - the wrong figure from a pressure or temperature sensor - a stuck-open EGR valve - the AdBlue system going wrong - injectors or glow plugs that stop a regeneration starting whatsoever - oil passing through the filter from a failing turbo That is what the first scan is for. If it proves to be one of those, you are warned before any work gets going rather than after you have paid for it. Lastly, two things. A vehicle with the filter cut out will fail its MOT, and driving it is an offence, so that is no remedy. What gets typed in as DPF renewal swaps nothing: your filter is cleared in place and goes back into service. ## DPF cleaning costs around Longbridge The treatment begins from £299. A call-out charge is added to every visit, and pays for the call-out itself, the booking, the scan and the advice that comes with it. Once we are told what you own, and about what the filter will need, the figure gets agreed on the phone. A single price for all would not be honest. The vehicle changes it, and so does the address — Longbridge, Crabtree, or anywhere farther out in the PL postcode area. Where the scan says a clean will not work, you are not billed for a clean. What nonetheless holds is the call-out charge, since the visit happened, the diagnostic was carried out and the advice was offered. Aftercare is taken in by a 30-day warranty: should the light return within it, an engineer comes back to Longbridge. ## The vehicles we clean and the patch we cover around Longbridge A single mobile service covers cars and estates, panel vans and light commercials, HGVs, plant and construction machinery and agricultural machinery, and on every one the filter is cleaned where it sits rather than taken anywhere. Week in week out there is by then someone on St Modwen Road, so Longbridge hardly ever means a detour, and Crabtree, Leigham and the spots past Sherford are on the way. It is the diary, not the distance, that picks whether it is today or tomorrow, and coverage runs UK-wide — so call anyway from further out across Devon. ## A word on Longbridge Longbridge is a small suburban area in Devon, situated near the coast and close to the city of Plymouth. Longbridge has a low elevation of around 2 metres, indicating its proximity to the sea. Longbridge is characterized by its semi-detached housing and is located near other suburban areas such as Marsh Mills and Leigham. ## Things Longbridge drivers ask about DPF cleaning Is a long drive enough by itself? It may, provided you catch it early enough and limp mode has not begun. It wants a sustained run at motorway speed, not fifteen minutes to The Food Warehouse and back. Roughly how long does it take? Allow typically around 2 hours — severely blocked filters sometimes need a second pass, which lengthens it. The cost around Longbridge — what is it? The call-out charge pays for the visit, the check and the advice; treatment itself begins from £299. We price on the phone, because the vehicle and your address both move the price. Must I be present in person? A spot for the motor to wait, for a couple of hours, is all that is required. Not you. Travel along if you like, and the regeneration is done as a monitored drive. When can someone travel to Longbridge? It is often same-day or next-day, depending on what is now in the calendar. One ring to 0303 330 1830 and you will learn what the PL area has available. Will the filter be removed? It is treated where it is, on the on-site service. Nor does taking a filter off nor fitting one back on is work we do. What if the light reappears? An engineer travels back out to Longbridge — the 30-day warranty includes aftercare. ## Book a DPF clean in Longbridge Phone 0303 330 1830 and talk us through what the vehicle is doing: a light, limp mode, smoke, whatever it is.
