--- title: Long Dean Mobile DPF Cleaning, Wiltshire canonical: https://mobiledpfcleaner.co.uk/mobile-dpf-cleaning/long-dean-wiltshire/ location: Long Dean county: Wiltshire latitude: 51.480030 longitude: -2.216180 service: Mobile DPF Cleaning updated: 2026-09-28 --- # Mobile DPF Cleaning in Long Dean, Wiltshire If the DPF warning light is lit and you are driving in Long Dean, mobile DPF treatment is the straightforward answer. You get a DPF engineer at your door across in Long Dean, a diesel particulate filter treated without coming off the vehicle, and a DPF regeneration carried out before they drive off. Rather than removing the car or pulling anything out, we leave the lot with you. Call 0303 330 1830 and we will go through a couple of questions about what the car is doing. With that clear, we will quote you the price and arrange a slot. You are paying from from £299 for mobile DPF treatment around Long Dean, and about two hours of an engineer's time. Filters block here because of the way people use the roads, not because of anything unusual about the place. It still surprises us the number of DPF cleans we carry out around Long Dean, given a population of only about 469. How committed the calendar already is will settle when an engineer gets to you. Most of the time that amounts to that same day or the next, across Long Dean and the rest of the SN postcode area. Our cleaning service does not break at a weekend, but the phones do keep normal hours: 7.30am to 6.30pm Monday to Thursday, and 7.30am to 5.30pm come Friday. ## Just what clogs diesel particulate filters around Long Dean If you drive to and from Long Dean, a rural hamlet, you are making the trips a DPF copes with worst. Think about your own week: By Brook Valley CofE Primary School and back, West Yatton Keynell Road at a crawl, a few minutes at M&S Simply Food, a short run to Chippenham. None of it goes on long enough for it or climbs hot enough to finish a regeneration cycle, so what should clear banks up instead. Just under 3 miles to the M4, and under 10 miles to Bath. Neither is far, but neither is on the way to anything most weeks, so units here seldom get the sustained drive that empties them. Hence the steady stream of calls from Long Dean and from Giddeahall and Yatton Keynell. Fuel economy is usually the first thing people pick up on getting worse. Stop/start goes quietly, acceleration tails off, the revs will not rise the way they should, and there may be a diesel odour in the interior or dark smoke on acceleration — often well before the light shows. The light merits attention even if it clears again by itself. ## Everything mobile DPF cleaning involves, once the van is around Long Dean Your own drive, a yard off A420, the M&S Simply Food car park round the corner while you get on with something else — the van operates wherever it can stop. Here is the sequence once it gets there. The engineer shows up in a fitted-out working van carrying everything the job calls for, so nothing has to be brought from a branch. Before any treatment commences, a system check is run and live readings pulled from the vehicle's ECU. That establishes how full the diesel particulate filter actually is, as a percentage and by soot weight, and checks the sensor readings, glow plugs and associated parts. The aim is to establish whether the DPF is actually the culprit, because a dashboard light by itself does not prove it. You cannot clear ash out with a burn cycle, which is why the cleaning solution is injected through the optimal entry point on the vehicle and given time to spread inside the filter. You may need a repeat clean if the blockage is a severe one. A regeneration run then drives out whatever is left. If you are about and willing to come along, that goes as a live regeneration on a monitored drive out of Long Dean — the type of run the unit has been denied. If not, a static burn is run on site and the live data checked after that. You get that warning light reset, the difference proved, and any stored codes still unresolved noted for you. All you require is somewhere the car can stand for the length of the job with the motor running at times. You do not have to hang about with the car at all. A drive over in Long Dean works, so does a workplace car park, so does a spare space near Castle Combe Circuit. ## How do our engineers know the diesel particulate filter is to blame? Two things fall out of the questions on the phone: whether DPF cleaning will solve the signs you have given us, and what the quote is. That is why they are raised, and it is not a box-ticking exercise. You have the figure agreed before a DPF engineer is dispatched to Long Dean. A choked DPF is what cleaning the DPF solves. Not everything that illuminates a dashboard has the same answer. Separating a choked DPF from everything else is the purpose of the check before cleaning. Where the fault proves to be an EGR valve, injectors, a turbo, an AdBlue system, plugs or a sensor, treatment will not fix it — and we say so up front rather than once the money has been paid. ## When you are going to need more than a DPF regeneration The easiest thing to try is a long unbroken run, and on a DPF unit that has only begun to load up it works. under 3 miles sits between Long Dean from the M4, and that is the journey to take, holding the cruise steady. The scenic way out to Bath does the same work. Five more minutes out to Ford and back does not. There is a point beyond which a regeneration by itself will not scour the DPF, and reduced power with the light on means you are well past it. An on-site cleaning visit in Long Dean is the next move. Before you choose, a couple of things are worth bearing in mind: - Taking it on the road without a serviceable DPF is illegal, and the vehicle will fail its MOT. Hollowing the unit out is not a solution. - No piece is changed on the on-site service. A clean is looked up as DPF renewal, but your existing filter sits where it is and goes back to work. A car that will not start at all calls for the other option, because treating it where it stands in Long Dean depends on the engine running. Twenty-four hours from receipt is the turnaround at our own workshop, plus overnight courier each way. The filter has to be removed and crated by you or your local garage first, then taken by courier. You will require a garage to take the filter off and fit it again, on either service. ## How much mobile DPF cleaning costs around Long Dean You are looking at from £299 for mobile DPF cleaning. What a given job works out at hinges on the motor and on what the unit proves to need, which is why the number is quoted over the phone rather than published as a flat figure. Tell us what you drive and broadly whereabouts you sit, whether that is up towards Roman villa, over by Giddeahall, in the middle of Long Dean, or further off in the SN postcode area. Both move the number. You will have the figure ahead of anyone being sent. Aftercare is not an add-on. It falls under the 30-day warranty the work includes. The question everybody asks is what follows if the light comes back. It is answered by a DPF engineer driving back to Long Dean inside the period, which is worth a good deal more than a badge on a website. ## Vehicles Mobile DPF Cleaner Long Dean cleans diesel particulate filters on round Long Dean There is no separate commercial service. The same on-site service is done on cars, on light commercials, on HGVs, on site and construction plant, and on agricultural machinery. The DPF is treated where it sits on all of them, at your address rather than our own. You are well inside the area whether you are in Long Dean, over in Giddeahall or Yatton Keynell, or out beyond Ford and Castle Combe. There is normally a van down West Yatton Keynell Road week in week out. Being away from Long Dean is nonetheless worth a call — coverage runs right across Britain, not just Wiltshire. You are sent both diagnostic sets of figures, from before cleaning and after it, together with advice matched to how the vehicle really gets driven round Long Dean. That last part is what prevents the filter from clogging again. A clogged catalytic converter is a different fault with different symptoms — flat response, a sulphur or rotten-egg smell, unusual warmth underneath, and frequently a P0420 fault code. Worth distinguishing the two, because they are easily confused, and we clean catalytic converters on the vehicle also. ## Long Dean at a glance Long Dean is a small hamlet situated on the riverside in Wiltshire, with a low elevation of around 72 metres.

Tell us what you run and where you are, whether that is across at Yatton Keynell, in Long Dean itself, or anywhere across the SN postcode area. Both change the figure, which begins from £299. Do you get to my address in Long Dean? Yes. An engineer comes to your home or workplace, right across Long Dean or the surrounding Wiltshire area. You hold on to the filter on the car throughout, because it is treated exactly where the vehicle sits. How fast is an engineer over to Long Dean? Often the same day or the one after, though it comes down to what is already booked. You will be given a direct answer on what is free in the SN postcode area the second you ring 0303 330 1830. How long am I without the car for a mobile DPF job? A severely loaded DPF takes cleaning twice and adds time, but around two hours is usual. Could I perhaps have the DPF cut out instead? You need it. A vehicle without a working DPF fails its MOT and using it is an offence, so taking it out is not a remedy and not something we offer. Am I protected if the DPF dash light shows again? An engineer returns to Long Dean. Aftercare of that sort is what the 30-day warranty includes. How long does a DPF cleaning last? That hinges on how the vehicle is driven after that. Longer runs — out past Bath, or on the M4 under 3 miles from Long Dean — do far more for it than short trips around Giddeahall and back. The engineer on the job will show you what works for your car. ## Book DPF cleaning and regeneration for Long Dean Phone 0303 330 1830 and tell us what the vehicle is up to.
