No workshop, no filter going anywhere. A technician travels to your door over in Hunston, cleans the diesel particulate filter where it is, carries out a DPF regeneration, and you keep the filter you started with. You'll have a figure by phone before anyone leaves, the clean opening from £299, and the visit taking typically around 2 hours. The light is showing and the motor is short of power — that is how we normally come across people, and roughly what this page deals with. ## DPF light on? What comes next First thing: it is not automatically the unit. That light can arise from plenty of faults, not just one, so the visit begins with a check and not with treatment. It counts what you manage with the vehicle between now and the booking. - A long even run may still manage it, provided the light is amber and the vehicle goes as normal. Costs zero, so try that before booking. - Once the car is in limp mode, driving will not shift it. The window has closed. - Get it looked at rather than driving it — diesel in the interior, or smoke on the throttle, has gone past the long-run stage. ## The car has been telling you already Last news, the light. The symptoms usually build for a while before it shows: - going uphill, the power tails off - an engine whose revs will not climb like they did - fuel use getting worse - stop/start quietly packing in - a diesel smell in the cabin, or smoke under hard acceleration Any one of those, taken by itself, is not conclusive. With the light, it is a fair guess the filter is blocked. ## The explanation diesel particulate filters choke round Hunston Being a coastal village, Hunston produces just the driving a DPF handles the poorest. Look at a typical week: North Mundham Primary School and home again, Southover Way at a crawl before half nine, a short hop to Waitrose, a run to Chichester. None of it there goes on long enough or is hot enough to complete a regeneration. Instead of burning away, the unburnt soot builds up. Geography does not oblige either. The Waterlooville Bypass is under 15 miles from Hunston and Chichester is under 3 miles away, so unless something takes you out that way often, entire weeks pass without the sustained run that would clear the filter alone. ## DPF regeneration, and the stage limp mode ends it What limp mode means is the motor defending itself. With output limited and the revs held, the regeneration the filter needs will not run at all. That tells, because triggering one is just what a long run does. The usual advice — get it up the motorway — is good, until it is not. The far side of that point — limp mode — more driving will not be enough, and the filter requires cleaning. ## Where the car stands is where the DPF is done across Hunston Most people do not see coming this bit: the filter remains. The job happens with the DPF still fitted to the motor — on your drive, in a work car park, anywhere the motor can wait for a couple of hours. First a check. Live ECU data, the soot load as a percent and as a figure, the sensor feeds, the glow plugs, the connected parts — all of it taken before any of it is touched. Soot and ash that a regeneration on its own will never shift are loosened next, by a solution put through the access point on that car, which opens out inside the filter. Sometimes a filter is clogged enough to take doing twice. A regeneration is next, burning off what the clean has freed. Either it is done as a monitored drive out of Hunston, with you present, or it runs where the vehicle stands and the live data is checked afterwards. Then a second scan, proving the change, putting out the warning light and noting anything still showing. Both sets of figures are emailed, so the before and after figures are recorded. ## Where treatment is not the solution A filter choked with soot and ash is the one thing cleaning cures. It will not reach: - temperature or pressure sensors reporting a blockage that is not there - the EGR valve stuck open - an AdBlue system fault - worn glow plugs or injectors, so no regeneration ever starts - the turbo passing oil into the filter That is what the first diagnostic is for. When one of those turns out to be the fault, you hear about it in advance rather than once the money has left already. DPF renewal is what people type in, but no part is swapped: the filter you have is treated where it sits and put back to work. Nor is having it gutted a remedy, since the MOT then fails and driving becomes illegal. Two more things worth knowing. ## The price for DPF cleaning around Hunston Treatment opens from £299, with the call-out charge on top of that for every visit — it takes in the call-out, the booking, the checks and the advice. Once we have what you run, and broadly what the filter will take, the figure gets agreed over phone. A single price for every job would not be straight. Two separate things shift it: what you run, and where you are — Hunston itself, over at Donnington, or farther out in the PO postcode area. Where the check says cleaning will not do it, you are not billed for cleaning. What even so holds is the call-out charge, since the visit took place, the diagnostic was carried out and the advice was given. Aftercare is taken in by a 30-day warranty: should the light reappear within it, an engineer heads back to Hunston. ## Where we reach around Hunston, and what we clean Cars and estates, vans and light commercials, heavy goods vehicles, plant machinery, farm vehicles — one on-site service across all of them, and on all of them the filter is cleaned where it sits rather than taken anywhere. Our engineers are along Southover Way nearly every week, so Hunston is rarely a journey of its own, and the same run takes in Donnington, North Mundham and the spots out past Runcton. Coverage runs UK-wide, so even further out through West Sussex is even so worth a phone call, and what decides between today and tomorrow is the diary rather than the distance. ## Hunston itself Hunston is a small village in West Sussex, situated near the coast and close to the city of Chichester. Hunston has a low elevation of around 4 metres, and its location near the sea has influenced its development. Hunston is characterized by its terraced housing and is part of a network of nearby villages, including Donnington and North Mundham. Hunston is also within commuting distance of London, being approximately 55.7 miles away. ## Frequent questions on DPF cleaning across Hunston Will a long drive clear it? If you get it early, and the car is not in limp mode, sometimes. It needs a sustained run at motorway speed, not ten minutes or so to Waitrose and back. Does the visit last long? Expect typically around 2 hours — heavily blocked filters sometimes take a second pass, which adds to it. Around Hunston, what does it run to? It opens from £299, plus the call-out charge covering the visit, the scan and the advice. Both the vehicle and where you are change it, which is why quoting happens by phone. Do I have to be around? The car needs a place for two hours or so. You do not need to be in it. Choosing to be there is no problem: the regeneration then runs out on the road, monitored. Can someone travel to Hunston soon? That hangs on the calendar, but it is often same-day or next-day. Call 0303 330 1830 and we will let you what is open across the PO area. The filter — does it come away from the car? Done where it stands, on this service, so no. We do not get filters off or put them back on, either way. And if the light comes back? Aftercare comes inside the 30-day warranty, and that includes an engineer coming back to Hunston. ## Organise DPF cleaning in Hunston Whatever it is doing — light, limp mode, smoke — mention so when you call 0303 330 1830.
