A fitter turns up at your address across Langley, clears the diesel particulate filter while it is attached to the motor, runs a DPF regeneration, and you hold on to the filter you came with. Budget for the visit taking typically around 2 hours. The clean begins from £299, agreed on the phone before anyone leaves. Most drivers find us with the light showing, and the motor low on power. That is exactly what this page is written for. ## Your DPF light is on — what now? Not the DPF, always. First thing to note. A scan goes before all work, because that same dash light has plenty of candidate faults behind it. Second thing: how you drive it between now and then counts. - Car yet driving as normal on an amber light — attempt a long constant run first. It costs nothing and frequently shifts the filter without assistance. - A drive will not reach it now — limp mode means that window has already shut. - Get it checked rather than running it — diesel in the car, or smoke on hard acceleration, has gone beyond the long-run stage. ## Before the light, what the car was telling you The light is last news. By the time it appears, the symptoms have usually been mounting for weeks: - pulling uphill, the power drops away - the revs no longer pull the way they used to - fuel use getting worse - the stop/start quietly packing in - diesel in the cabin, or smoke on the way up through the box None of that is evidence alone. With the light, it is a fair guess the filter is loaded. ## The reason diesel particulate filters clog around Langley The day-to-day driving that goes with a residential suburb like Langley is the worst type for a DPF. The school run to Marish Primary School, Spencer Road at a standstill at half past eight, a few minutes to Co-op Food, the hop to the nearest station — nothing of it lasts long enough or gets hot enough for the filter to see through a regeneration. What should clear stays behind. Neither is a long way from Langley: under a mile to the M4, under 25 miles to Westminster. Neither is on the way to anything most weeks, though, so the drive that would scour a filter never gets made. ## DPF regeneration, and the moment limp mode kills it The car is protecting itself, which is what limp mode amounts to. A long drive works by setting off a regeneration, and that is precisely what limp mode blocks: power limited, revs pinned, no regeneration possible. Sensible advice, that motorway run — until the day it is not. The filter needs cleaning rather than more driving once the motor has gone into limp mode. ## Where the motor stands is where the DPF is treated across Langley On your driveway, in a work car park, anywhere the motor can sit for a couple of hours: the job is done with the filter yet bolted on, which is the bit most owners do not anticipate. Nothing is touched until other faults are cleared. That requires a scan first: real-time data off the ECU, soot load by proportion and by weight, and a check of the sensor readings, glow plugs and associated components. Then the clean. A cleaning solution is fed in through the access port on that vehicle and opens out inside the filter, lifting the soot and ash a regeneration on its own will never move. Where the filter is severely blocked, expect a second pass. Then a regeneration, to drive off what the clean has loosened. If you are there, that is run as a monitored drive out of Langley; if not, on the spot where the motor stands, with the running data checked after. Both sets of figures go over by email, so the figures from either end are recorded. The second scan is what proves the change, clears the light and logs whatever is still showing. ## The problems a DPF clean cannot answer One thing is what cleaning fixes — a filter blocked with soot and ash. It does no good for: - sensors, pressure or temperature, reporting a restriction that is not real - EGR valves that stick open - a problem in the AdBlue system - injectors or glow plugs that prevent a regeneration starting at all - a turbo pushing oil through the filter Which is why the check goes first. When one of those proves the fault, you hear about it at the outset rather than once the money has gone already. Lastly, two things. A vehicle with the filter hollowed out fails its MOT, and driving it is illegal, so that is no fix. What gets searched for as DPF renewal swaps nothing: your existing filter is treated in place and goes back into service. ## What DPF cleaning costs around Langley The cleaning opens from £299. A call-out charge is added to every visit, and pays for the call-out itself, the booking, the check and the advice that comes with it. The number is agreed by the phone, once we are told the vehicle and what the filter is likely to need. No flat rate could be honest. What you drive and where you are both change it: Langley itself, across at Sutton, or further out within the SL postcode area. Where the scan says treatment will not help, you are not asked to pay for a clean. Because the visit, the diagnostic and the advice have happened, the call-out charge nonetheless holds. If the light comes back inside that time, an engineer heads back out to Langley — the clean carries a 30-day warranty including aftercare. ## Vehicles we clean, and where we reach round Langley Cars, vans of any size and light commercials, HGVs, plant machinery, agricultural vehicles — the one mobile service across all of them, and on all of them the filter is treated where it sits rather than moved anywhere. Most weeks there is usually someone on Spencer Road, so Langley hardly ever means a special trip, and Sutton, Middle Green and the spots past Colnbrook come with it. It is the diary, not the distance, that picks whether it is this day or the next, and coverage extends UK-wide — so call anyway from even further out through Berkshire. ## The ground around Langley Langley is a suburban area in Berkshire, situated inland at an elevation of 28 metres, and is located approximately 18 miles from London.

If you get it early enough, and the vehicle is not in limp mode, sometimes. It needs a sustained run at motorway speed, not fifteen minutes flat to Co-op Food and back. Roughly how long does it last? That is typically around 2 hours, though a badly blocked filter can take cleaning twice, which takes longer. Around Langley, what does it run to? It opens from £299, plus the call-out charge taking in the visit, the diagnostic and the advice. The vehicle and your address both shift the number, so we price on the phone. Do I have to be around? You need not stand with it — the vehicle just requires space to wait for a couple of hours. Wanting to be there is welcome: the regeneration then runs out on the move, monitored. Can someone get to Langley soon? It is often same-day or next-day, depending on what is already in the calendar. Ring 0303 330 1830 what is available across the SL area. Is the filter removed from the motor? Cleaned where it stands, on this service, so no. Neither job — a filter off, a filter back on — is not work we do. Suppose the light comes back? Aftercare sits inside the 30-day warranty, and that includes an engineer heading back to Langley. ## Put a DPF clean booked around Langley Whichever it is doing — light, limp mode, smoke — say so when you call 0303 330 1830.
