Your motor will not be taken away and the filter does not budge. An engineer arrives at your place in Ashton, clears the diesel particulate filter fitted to the motor and performs a DPF regeneration. The visit takes typically around 2 hours, the clean starts from £299, and the price is agreed by the phone before anyone travels. The light is showing and the car is down on power — that is how we normally meet people, and what this page is about. ## What to check when the DPF light is on Not the filter, always. First thing to say. Treatment is not where a visit begins. A diagnostic is — several faults register as the same warning. Second thing: how you handle it between now and then makes a difference. - Vehicle still driving as normal on an amber light — have a go at a long constant run first. It costs nothing at all and regularly sorts the filter without help. - Once the motor is in limp mode, a long run will not reach it. The window has shut. - Diesel smell in the car, or black smoke under hard acceleration — stop arranging long drives and get it seen to. ## What the car has been showing you The light is belated news. By the time it arrives, the symptoms have normally been building for weeks: - power tailing off, especially climbing uphill - an engine whose revs will not rise as before - the fuel consumption is poorer - silently, the stop/start gives up - a diesel smell in the interior, or smoke under acceleration By itself, none of that is conclusive. Next to the light alongside them, the filter is a fair bet. ## What clogs diesel particulate filters around Ashton For a DPF, the least kind use is the sort you get around a rural hamlet such as Ashton. A regeneration wants long enough and heat, and sees not much: not on the school run to Bishops Waltham Infant School, not on Ashton Lane at half eight, not on a few minutes to The Co-operative Food, and not on the dash to Botley. Instead of burning off, the soot collects. The M27 sits under 10 miles from Ashton, Winchester under 10 miles away, and unless something pulls you out that way often, whole weeks slip past without the long unbroken run that scours a filter. Geography does not oblige. ## Why limp mode blocks a DPF regeneration Limp mode is the motor protecting itself. The real difficulty is that a sustained drive works by triggering a regeneration, and once in limp mode the revs will not climb and power is limited. The standard advice — take it up the motorway — is good, right until it is not. Past that point — limp mode — driving will not manage it, and the filter wants cleaning. ## The motor stays in place for mobile DPF cleaning in Ashton Nothing is taken from the car. That surprises people. The DPF sits fitted where it is and the work goes on around it, on a forecourt, in a works car park, wherever it can sit for a couple of hours. A diagnostic happens first — running data off the ECU, soot load by percent and by actual weight, and a look over of the sensor feeds, glow plugs and associated parts, so other faults are cleared before a thing is cleaned. After that comes the clean itself: a cleaning solution in through the car's own access port, opening out inside the filter and loosening what a regeneration cannot. Sometimes a filter is clogged enough to take doing twice. Then a regeneration, to drive off what the clean has lifted. If you are there, that is carried out as a monitored drive out of Ashton; if not, in place where the car waits, with the live data read afterwards. Finally the scan runs again — the change verified, the light reset, anything still outstanding logged. Both read-outs reach you by email, so the numbers are recorded. ## When a DPF clean is not the fix A filter blocked with soot and ash is the one thing treatment cures. It will not touch: - temperature or pressure sensors showing a blockage that is not there - a jammed EGR valve - an AdBlue system failure - a regeneration that simply never starts, because of glow plugs or injectors - oil working through the filter from a failing turbo The first diagnostic is there for just that. Where it proves to be one of those, you are warned before any work starts rather than after you have paid anything. Two things more worth bearing in mind. Getting the filter hollowed out is not a remedy — a vehicle without a working DPF will fail its MOT and driving it is an offence. And cleaning is sometimes looked up as DPF renewal: nothing is replaced, your original filter is treated in place and put back into use. ## What DPF cleaning runs to across Ashton A clean begins from £299, with the call-out charge on top of that for every visit — it pays for the call-out, the booking, the scans and the advice. The price is settled over the phone, once we are told the vehicle and what the filter is apt to need. No flat rate could be honest. What you own and where you are both change it: Ashton itself, out at Street End, or farther out in the SO postcode area. Where the check says a clean will not do it, you are not billed for treatment. You even so pay that charge: someone came out, ran the diagnostic and gave you the advice. Aftercare is covered by a 30-day warranty: should the light return within it, an engineer heads back to Ashton. ## What we clean, and how far we go around Ashton Whatever it is — estate, van, light commercial, heavy goods vehicle, plant, construction machinery, agricultural vehicle — the same call-out service holds, and the filter never departs it. The same round that keeps engineers on Ashton Lane most weeks takes in Ashton, Street End, Bishops Waltham and the places beyond Upham. Farther out through Hampshire is still worth ringing about — coverage runs UK-wide, and it is the diary rather than the distance that decides between one day and the next. ## About Ashton Ashton is a small hamlet in Hampshire, situated inland at an elevation of around 80 metres, approximately 7.5 miles from Winchester. Ashton lies within the wider countryside of the South East region, with the nearest major city being Winchester and London being around 60 miles distant. Ashton is characterised by its predominantly detached housing stock, reflecting its rural setting. Ashton is close to other small settlements such as Street End, Dean, and Northbrook. ## Questions Ashton drivers ask about DPF cleaning Can I simply take it for a long drive? If you get it early enough, and the vehicle is not in limp mode, sometimes. That means motorway speed for a sustained stretch, rather than a quick trip to The Co-operative Food. How long does the visit take? That is typically around 2 hours, though a heavily clogged filter can need cleaning twice, which adds time. Cost across Ashton — what is it? The call-out charge pays for the visit, the check and the advice; cleaning itself begins from £299. The vehicle and your address both shift the number, so we settle it on the phone. Must I be there in person? You do not need to stand with it — the motor only needs space to wait for a couple of hours. If you would rather come along, the regeneration can be carried out as a supervised drive instead. Coming to Ashton — how soon? Depending on the diary, often same-day or next-day is usual. One ring to 0303 330 1830 and you will know what the SO area has available. Is the filter taken off the motor? Not on the on-site service — it is treated where it sits. That job — a filter off, a filter back on — is not work we do. Suppose the light reappears? The 30-day warranty covers aftercare, including an engineer coming back to Ashton. ## Have a DPF clean booked around Ashton Whatever it is doing — light, limp mode, smoke — mention so when you phone 0303 330 1830.
