No workshop, no filter going anywhere. An engineer travels to your address across Highways, cleans the diesel particulate filter in place, runs a DPF regeneration, and you end up with the filter you arrived with. Reckon on the visit lasting typically around 2 hours. The clean begins from £299, settled by the phone before anyone sets off. If the light is already on and the car is down on power, this page is the right one. That is how most drivers arrive here. ## What to check when the DPF light shows The unit is not automatically what is at fault, and that goes first. Several faults put the very same light on the identical panel, which is why a visit starts with a scan rather than with treatment. It counts what you get with the motor between now and the visit. - A long steady run may yet be enough, provided the light is amber and the vehicle goes as normal. Costs zero, so have a go at that before ringing. - A drive will not touch it now — limp mode means that window has already gone. - Diesel smell in the interior, or black smoke under hard acceleration — stop arranging long drives and get it checked. ## What the motor has been showing you The light is late news. By the time it arrives, the symptoms have normally been growing for some time: - going uphill, the power falls off - revs that will not rise the way they used to - worse fuel consumption - silently, the stop/start gives up - a diesel smell in the interior, or smoke under acceleration That is not evidence on its own. With the light beside them, the filter is a fair guess. ## Why diesel particulate filters clog around Highways For a DPF, the poorest motoring is the type you get across a rural hamlet such as Highways. None of it lasts long enough or is hot enough for the filter to complete a regeneration: the school run to Micheldever CofE Primary School, Cowdown standing at the morning rush, five minutes to The Co-operative Food, the dash to Micheldever. What should burn off remains. The M3 sits under a mile from Highways, Winchester under 10 miles off, and unless something carries you out that way regularly, full weeks slip past without the sustained run that empties a filter. Geography does not assist. ## Why limp mode stops a DPF regeneration The vehicle is protecting itself, which is what limp mode amounts to. With output capped and the revs kept low, the regeneration the filter requires will not happen at all. That counts, because triggering one is exactly what a motorway run does. So the standard advice to take it up the motorway is sensible advice, right until it stops being. The filter needs cleaning rather than road work once the vehicle has gone into limp mode. ## DPF cleaning at the vehicle in Highways On your front, in a work car park, any place the car can wait for a while: the job is done with the filter even now fixed on, which is the part most owners do not expect. Nothing is touched until other faults are ruled out. That requires a scan first: running data off the ECU, soot load by proportion and by mass, and a check of the sensors, glow plugs and associated components. After that comes the clean itself: a cleaning solution in through the car's own entry point, spreading inside the filter and freeing what a regeneration cannot. Sometimes a filter is loaded enough to need doing twice. What the clean has freed is then driven off by a regeneration. That is a monitored drive out of Highways if you are along, or a static regeneration where the vehicle sits, with the running data checked afterwards. Finally the check runs again — the change verified, the light reset, anything still open noted. Both sets of figures arrive with you by email, so the numbers are recorded. ## When a DPF clean is not the answer A filter clogged with soot and ash is the one thing cleaning fixes. It will not help: - a temperature or pressure sensor reporting a restriction that is not there - EGR valves that jam open - the AdBlue system playing up - glow plugs or injectors preventing the regeneration starting at all - a turbo putting oil through the filter That is what the first check is for. You are warned before the work starts, not after you have paid, should it turns out to be one of those. Gutting the filter out is not a solution: without a serviceable DPF a vehicle will fail its MOT, and driving it is against the law. DPF renewal is the wording people type in, though nothing is swapped — your own filter is treated in place and returned into use. Two more worth bearing in mind. ## Figures for DPF cleaning around Highways A call-out charge applies whatever follows, and pays for the visit, the booking fee, the diagnostic and the advice offered. Treatment itself opens from £299. The figure is fixed over the phone, once we know the vehicle and what the filter is likely to need. No flat rate could be straight. The car moves it, and so does the location — Highways, East Stratton, or a spot farther out in the SO postcode area. If the scan rules cleaning out, there is nothing to pay for it. Because the visit, the scan and the advice have taken place, the call-out charge still holds. If the light reappears inside that window, an engineer heads back out to Highways — the work comes with a 30-day warranty including aftercare. ## Where we travel round Highways, and what we clean The filter is cleaned on the vehicle on all of them: cars and estates, vans of any size and light commercials, HGVs, construction and plant machinery, agricultural vehicles. Nothing is taken anywhere. The same run that puts our engineers on Cowdown most weeks covers Highways, East Stratton, Northbrook and the villages beyond Micheldever. Coverage runs UK-wide, so farther out across Hampshire is nonetheless worth a ring, and what picks between today and tomorrow is the diary rather than the distance. ## A word on Highways Highways is a small hamlet in Hampshire, situated inland at an elevation of 86 metres, approximately 6.7 miles from Winchester. Highways is surrounded by nearby places such as West Stratton, Micheldever, and East Stratton, and is characterized by its semi-detached housing. Highways is located in the South East region of England, about 54.2 miles from London. ## Things Highways drivers ask about DPF cleaning Does a long run sort it? Soon enough, and with the motor out of limp mode, yes — sometimes. It wants a long run at motorway speed, not ten minutes flat to The Co-operative Food and back. About how long does it take? That is typically around 2 hours, though a badly clogged filter can require cleaning twice, which runs on. What does it come to around Highways? Starting from £299, with a charge for coming out that pays for the diagnostic and advice on what to do next. Both the vehicle and where you are change it, which is why quoting goes by phone. Have I have to be present? Somewhere for the vehicle to stand, for a couple of hours, is all that is wanted. Not you. If you would rather come along, the regeneration can be run as a watched drive instead. Travelling to Highways — how soon? It is often same-day or next-day, depending on what is now in the schedule. Ring 0303 330 1830 and we will tell you what is free across the SO area. Will the filter be taken off? Treated where it sits, on this service, so no. Lifting a filter off or putting one back on come to anything work we do in either direction. And if the light reappears? The 30-day warranty includes aftercare, including an engineer coming back to Highways. ## Book a DPF clean around Highways Whatever it is doing — light, limp mode, smoke — mention so when you phone 0303 330 1830.
