A fitter comes at your place over in New Town, clears the diesel particulate filter while it is fitted to the vehicle, carries out a DPF regeneration, and you hold on to the filter you started with. You'll be given a number by phone before anyone departs, the clean beginning from £299, and the visit lasting typically around 2 hours. The light is showing and the vehicle is short of power — that is how we generally meet people, and what this page covers. ## What to do when the DPF light shows It may not be the unit whatsoever. That is the first thing. Plenty of faults put the same light on the same dash, which is why a visit opens with a diagnostic rather than with a clean. It counts what you do with the vehicle between now and the appointment. - Worth a try before you book anything: amber light, vehicle driving normally, just one constant run, no cost. - Motor already fallen into limp mode — that window has gone. A drive will not touch it now. - A diesel smell inside, or black smoke under hard acceleration, is the point to stop planning long drives and ring. ## What the car has been warning you The light is late news. By the time it shows, the symptoms have usually been building for weeks: - dropping away on power, particularly uphill - you find the revs never reach where they used to go - the fuel economy is worse - a stop/start that has meekly given up - a diesel smell in the car, or smoke under acceleration Any one of those, taken alone, is not conclusive. It is a fair guess the filter is full once the light is showing too. ## What blocks diesel particulate filters near New Town New Town is a rural hamlet, and the day-to-day driving that comes with one is the poorest kind for a DPF. None of it runs long enough or runs hot enough for the filter to finish a regeneration: the school run to Trinity Church of England Primary School, M4 standing at half eight, a few minutes to M&S Simply Food, the hop to Chippenham. Instead of burning off, the soot load collects. Neither is a long way from New Town: under a mile to the M4, under 15 miles to Bath. Neither is on the way to much most weeks, though, so the drive that would empty a filter hardly ever gets made. ## DPF regeneration, and the point limp mode kills it Limp mode is the motor defending itself. The entire problem is that a long drive works by setting off a regeneration, and once in limp mode the revs will not rise and power is capped. The usual advice — take it up the motorway — is sound, up until it is not. The filter needs cleaning rather than driving once the car has slipped into limp mode. ## Where the car stands is where the DPF is cleaned across New Town On your front, in a work car park, wherever the car can sit for a couple of hours: the job happens with the filter yet fitted on, which is the bit most drivers do not expect. A scan goes first — real-time data off the ECU, soot load by percent and by mass, and a look over of the sensors, glow plugs and associated components, so other faults are eliminated before anything is touched. Then comes the clean itself: solution in through the vehicle's own access point, opening out inside the filter and loosening what a regeneration never can. Where the filter is heavily loaded, allow for a second pass. What the clean has freed is then burned off by a regeneration. That is a monitored drive out of New Town if you are there, or a static regeneration where the motor sits, with the running data verified afterwards. Then a second check, verifying the change, clearing the warning light and logging anything still showing. Both read-outs are emailed over, so the before and after figures are kept. ## The faults a DPF clean cannot answer Only one fault is fixed by a clean: the filter clogged with ash and soot. It does little for: - sensors, pressure, reporting a blockage that is not real - an EGR valve held open - a fault in the AdBlue system - injectors or glow plugs that block a regeneration starting in the first place - turbo failure, with oil entering the filter Which is why the scan comes first. You are let know before any work starts, not after you have settled up, if it turns out to be one of those. Cutting the filter out is not a remedy: without a functioning DPF a vehicle cannot pass its MOT, and driving it is against the law. DPF renewal is the wording people look up, though nothing is replaced — your existing filter is cleaned in place and put back into use. Two more worth bearing in mind. ## What DPF cleaning runs to around New Town Cleaning begins from £299, with the call-out charge on top of that for every visit — it pays for the call-out, the booking, the checks and the advice. Once we are told what you run, and roughly what the filter will take, the number gets agreed over phone. A single price for everyone would not be truthful. Two separate things move it: what you run, and where you are — New Town itself, out at Littleton Drew, or further out in the SN postcode area. A clean that will not work is not a clean you pay for, and the diagnostic is what says so. You still pay that charge: someone travelled, did the scan and offered you the advice. Aftercare is included by a 30-day warranty: should the light return within it, an engineer returns to New Town. ## Where we get to round New Town, and what we clean Cars, vans and light commercials, heavy goods vehicles, plant machinery, agricultural vehicles — a single mobile service across all of them, and on all of them the filter is done on the vehicle rather than carried anywhere. The same run that keeps engineers on M4 most weeks covers New Town, Littleton Drew, The Gibb and the places beyond Burton. Call anyway from farther out across Wiltshire. Coverage reaches UK-wide, and the day you are offered hangs on the calendar rather than how far away you are. ## About New Town New Town is a small hamlet in Wiltshire, situated on the riverside at an elevation of 131 metres, with detached housing being the predominant type of accommodation.

Sometimes, if you spot it early and the car has not dropped into limp mode. Ten minutes to M&S Simply Food and back will not be enough; motorway speed, held for some time, will. About how long does it take? That is typically around 2 hours, though a badly blocked filter can need cleaning twice, which adds time. What does it run to in New Town? Treatment opens from £299, and the call-out charge on top pays for the visit, the check and the advice. The vehicle and your address both move the figure, so we settle it on the phone. Have I need to be around? No. The motor wants space to wait for a couple of hours; nobody expects you to stand with it. Ride along if you would rather, and the regeneration is done as a supervised drive. How soon can someone travel to New Town? 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 open across the SN area. Will the filter be removed? Treated where it sits, on this service, so no. Getting a filter off or fitting one back on amount to anything a job we do in either direction. And if the light returns? An engineer travels back out to New Town — the 30-day warranty includes aftercare. ## Booking a DPF clean in New Town Call 0303 330 1830 and set out what the motor is doing: a light, limp mode, smoke, whatever it is.
