Your vehicle will not be taken anywhere and the filter does not leave it. A technician turns up at your address across The Close, cleans the diesel particulate filter still on the motor and carries out a DPF regeneration. The visit runs typically around 2 hours, the clean opens from £299, and the figure is settled over the phone before anyone sets off. Written for the situation most callers are in: the light on already, the vehicle struggling for power, and the visit still to arrange. ## DPF light on? What happens next It could not be the unit whatsoever. That is the opening thing. Plenty of faults put the same light on the very same dashboard, which is why a visit starts with a scan rather than with treatment. It tells what you do with the motor between now and the appointment. - Amber light, car even now driving normally — a long constant run can still sort it on its own. Costs nothing at all, and worth attempting before you book anything. - That window has closed once the motor has fallen into limp mode. Driving will not get there now. - A diesel smell inside, or black smoke under the throttle, is the moment to stop arranging long drives and call. ## The motor has been showing you already By the time the light shows, things have generally been slipping for weeks. It is late news: - less power, especially pulling uphill - an engine whose revs will not climb as they should - worse fuel consumption - a stop/start that has quietly given up - the car smelling of diesel, or smoke when you accelerate By itself, none of that is evidence. Next to the light, it is a fair assumption the filter is full. ## The reason diesel particulate filters choke round The Close For a DPF, the least kind driving is the kind you get in a residential suburb such as The Close. The school run to St Richard's Catholic Primary School, West Pallant at a crawl at half past eight, a few minutes to Waitrose, the dash to Chichester — not one bit of it lasts long enough or is hot enough for the filter to finish a regeneration. What should burn away stays put. The A3(M) lies under 15 miles from The Close, Chichester under a mile off, and unless something pulls you out that way regularly, entire weeks slip past without the sustained run that scours a unit. Geography does not assist. ## DPF regeneration, and the stage limp mode stops it What limp mode amounts to is the vehicle protecting itself. A long drive works by setting off a regeneration, and that is exactly what limp mode blocks: power limited, revs held down, no regeneration possible. Sensible advice, that motorway run — up until the day it is not. Once the vehicle is in limp mode you are the far side of that point, and the filter requires treatment rather than driving. ## The motor stays in place for on-site DPF cleaning round The Close Nothing leaves the motor. That surprises people. The DPF stays fitted where it is and the work goes on around it, on a forecourt, in a works car park, anywhere it can sit for a few hours. Nothing is touched until other faults are ruled out. That involves a check first: running data off the ECU, soot load by percent and by weight, and a check of the sensor feeds, glow plugs and related parts. Then the treatment. A cleaning solution is injected through the entry point on that motor and spreads inside the filter, freeing the soot and ash a regeneration by itself will never budge. Where the filter is heavily blocked, allow for a second pass. A regeneration follows, clearing what the clean has freed. That is a monitored drive out of The Close if you are present, or a static regeneration where the motor sits, with the live data verified afterwards. Then a second diagnostic, proving the change, resetting the warning light and noting anything still outstanding. Both read-outs are sent over, so the before and after figures are kept. ## The problems a DPF clean cannot fix One thing is what treatment answers — a filter clogged with soot and ash. It does nothing for: - the wrong signal from a temperature or pressure sensor - an EGR valve jammed open - the AdBlue system failing - injectors or glow plugs that block a regeneration starting whatsoever - a turbo passing oil through the filter That is what the first scan is for. Where one of those turns out to be the fault, you hear about it in advance rather than once the money has changed hands already. Cutting the filter out is not a solution: without a serviceable DPF a vehicle fails its MOT, and driving it is against the law. DPF renewal is the term people look up, though nothing is replaced — your own filter is cleared in place and returned into use. Two more worth knowing. ## Costs for DPF cleaning around The Close Cleaning begins from £299, with the call-out charge on top of that for every visit — it covers the call-out, the booking, the scans and the advice. Once we are told what you run, and broadly what the filter will want, the figure gets agreed by phone. A single price for everyone would not be truthful. A pair of things shift it: what you own, and where you are — The Close itself, across at Chichester, or otherwise out within the PO postcode area. You are not asked to pay for treatment that the scan says will not work. You still pay that charge: someone travelled, did the diagnostic and offered you the advice. A 30-day warranty takes in aftercare on the job, and that includes an engineer travelling back out to The Close if the light reappears inside the window. ## Vehicles we clean, and where we reach round The Close The filter is treated where it sits on all of them: cars, vans and light commercials, heavy goods vehicles, construction and plant machinery, agricultural vehicles. Nothing is taken anywhere. Engineers are along West Pallant most weeks, so The Close is rarely a detour, and the same run picks up Chichester, Whyke and the spots out past Fishbourne. It is the calendar, not the distance, that picks whether it is today or tomorrow, and coverage runs UK-wide — so phone even from farther out around West Sussex. ## A line on The Close The Close is a suburban area situated on the outskirts of Chichester in West Sussex, with a riverside setting and an elevation of around 17 metres. The Close is characterized by its predominantly flat housing stock, which reflects the area's relatively low-lying terrain. The Close is located close to the city centre of Chichester, with nearby neighbourhoods including Whyke and Stockbridge. The Close has a population of approximately 5433 residents. ## What The Close drivers wonder about DPF cleaning Does a long run sort it? If you spot it in time, and the car is not in limp mode, sometimes. A sustained run at motorway speed is what it takes — not ten minutes flat to Waitrose and back. About how long does it last? Count on typically around 2 hours, with a second clean adding to that where the filter is heavily loaded. What does it come to across The Close? It begins from £299, plus the call-out charge covering the visit, the diagnostic and the advice. Both the vehicle and where you are change it, which is why pricing goes by phone. Do I have to be there? No. The motor needs space to sit for a couple of hours; nobody expects you to stand with it. Choosing to be there is welcome: the regeneration then runs out on the road, monitored. Can someone travel to The Close soon? It is often same-day or next-day, depending on what is now in the calendar. Ring 0303 330 1830 and we will say to you what is open across the PO area. Will the filter be lifted off? On the on-site service, no: the filter is treated in place. Taking a filter off or bolting one back on count as anything a job we do in either direction. Suppose the light comes back? Aftercare sits inside the 30-day warranty, and that includes an engineer heading back to The Close. ## Arrange DPF cleaning across The Close Ring 0303 330 1830 and tell us what the motor is doing — a light, limp mode, smoke, whatever it is. The price is settled first, and so does the date, before anyone sets off for The Close. Out of phone hours, email enquiries@dpf-fixer.co.uk and it is dealt with first thing.
