Your vehicle will not be taken anywhere and the filter will not leave it. An engineer turns up at your place across Hartley Hill, treats the diesel particulate filter still on the motor and carries out a DPF regeneration. The visit runs typically around 2 hours, the clean begins from £299, and the number is fixed on the phone before anyone leaves. Written for the position most owners are in: the light already on, the vehicle short for power, and the clean still to fix. ## DPF light on? What comes next It may not be the DPF at all. That is the first thing. That light can come from several faults, not merely one, so the visit starts with a scan and not with treatment. The use you get in the meantime matters. That is the second thing. - Motor yet driving normally on an amber light — have a go at a long steady run first. It costs nothing at all and regularly sorts the filter without help. - Once the motor is in limp mode, driving will not shift it. The window has shut. - A diesel smell in there, or black smoke under acceleration, is the stage to stop arranging long drives and ring. ## Signs the motor has been giving you The light is late news. By the time it arrives, the symptoms have normally been building for some time: - power tailing off, particularly going uphill - the revs no longer pull the way they once did - fuel consumption getting worse - a stop/start that has meekly bowed out - a diesel smell in the interior, or smoke under hard acceleration None of that is conclusive on its own. The light with them points at a blocked filter. ## The cause diesel particulate filters choke round Hartley Hill Hartley Hill is a residential suburb, and the driving that belongs to one is the worst kind for a DPF. The school run to New Ash Green Primary School, Hartley Hill at a crawl at the morning rush, ten minutes to Co-op Food, the hop to Longfield — none of it lasts long enough or is hot enough for the filter to see through a regeneration. The soot banks up rather than clearing. Neither is a long way from Hartley Hill: under 3 miles to the M20, under 25 miles to London. Neither is on the way to anything most weeks, though, so the run that would empty a filter never comes. ## Why limp mode prevents a DPF regeneration It is self-defence: that is all limp mode is. With pulling power limited and the revs pinned, the regeneration the filter needs can never happen at all. That tells, because triggering one is exactly what a long run does. So the standard advice to get it up the motorway is sound advice, until it stops being. The far side of that point — limp mode — driving will not do it, and the filter wants cleaning. ## DPF cleaning at the vehicle across Hartley Hill The filter does not budge. That is the bit most drivers do not see coming: the job takes place with the DPF still fixed to the vehicle, on your drive, in a work car park, any place the vehicle can stand for a couple of hours. A check comes first — running data off the ECU, soot load by proportion and by weight, and a check of the sensor readings, glow plugs and connected components, so other faults are cleared before anything is touched. Then the clean. A solution is fed in through the access port on that car and spreads inside the filter, loosening the soot and ash a regeneration by itself will never move. Where the filter is heavily clogged, plan on a second pass. Then a regeneration, to drive off what the clean has loosened. Ride along with the motor and it becomes a monitored drive out of Hartley Hill. Leave it and the regeneration goes in place, with live data read once it is done. Finally the check runs again — the change verified, the light reset, anything still outstanding noted. Both reports reach you by email, so the numbers are on record. ## The problems a DPF clean cannot fix A filter choked with soot and ash is the one thing a clean fixes. It will not reach: - sensors, pressure or temperature, showing a blockage that is not real - a stuck-open EGR valve - an AdBlue system failure - a regeneration that simply never starts, because of glow plugs or injectors - oil coming through the filter from a worn turbo That is what the first check is for. Turning out to be one of them means hearing it before the work begins, not after settling up a penny. Gutting the filter out is not a remedy: without a working DPF a vehicle fails its MOT, and driving it is illegal. DPF renewal is the phrase people look up, though nothing is swapped — your original filter is cleaned in place and sent back into use. Two more worth noting. ## DPF cleaning prices around Hartley Hill Every visit attracts a call-out charge — travelling to you, taking the booking, running the check and offering the advice. The clean itself opens from £299. Quoting a flat rate would not be truthful. We agree it over phone, once the vehicle and its likely needs are known. Whereabouts you are tells as much as what you own: Hartley Hill itself, New Ash Green next door, or otherwise out across the DA postcode area. You are not billed for treatment that the diagnostic says will not do it. Because the visit, the diagnostic and the advice have taken place, the call-out charge nonetheless applies. Aftercare is included by a 30-day warranty: should the light come back within it, an engineer returns to Hartley Hill. ## The vehicles we clean and the patch we take in around Hartley Hill A single on-site service takes in private cars, vans of any size and light commercials, HGVs and lorries, plant and construction machinery and agricultural machinery, and on every one the filter is cleaned in place rather than carried anywhere. Hartley Hill is hardly ever a special trip: engineers are out on Hartley Hill most weeks, and the same run takes in New Ash Green, Ash and the villages out past West Yoke. Phone anyway from even further out around Kent. Coverage reaches UK-wide, and the day you are given depends on the diary rather than how far away you are. ## About Hartley Hill Hartley Hill is a suburban area in Kent, situated inland at an elevation of 128 metres, and is located approximately 21 miles from London.

Sometimes, if you get it in time and the motor has not fallen into limp mode. Ten minutes to Co-op Food and back will not do it; motorway speed, held for some time, will. Broadly how long does it last? Expect typically around 2 hours — badly blocked filters sometimes need a second pass, which adds to it. How much does it come to in Hartley Hill? It starts from £299, plus the call-out charge paying for the visit, the scan and the advice. We price on the phone, because the vehicle and your address both move the number. Have I got to be present? The vehicle needs a place for two hours or so. You need not be in it. If you would prefer to come along, the regeneration can be done as a supervised drive instead. When can someone come to Hartley Hill? You are offered often same-day or next-day, though it depends what is currently in the schedule. One ring to 0303 330 1830 and you will know what the DA area has open. Is the filter taken off the vehicle? It is cleaned where it sits, on the mobile service. We do not take filters off or bolt them back on, whichever way. Suppose the light reappears? Aftercare comes inside the 30-day warranty, and that includes an engineer heading back to Hartley Hill. ## Setting up a DPF clean around Hartley Hill Phone 0303 330 1830 and describe what the vehicle is doing: light, limp mode, smoke, whatever it is.
