The engineer pulls up at your door in Fontwell and sets up. The diesel particulate filter is treated on the motor, a DPF regeneration follows, and you keep the filter you came with. The visit lasts typically around 2 hours, the clean starts from £299, and the price is agreed on the phone before anyone leaves. The light is already on and the car is short of power — that is how we usually find people, and precisely what this page is about. ## The DPF light is on. What now? The filter is not always what is to blame, and that comes first. That light can follow several faults, not merely one, so the visit starts with a scan and not with treatment. It tells what you get with the motor between now and the visit. - Motor yet driving normally on an amber light — have a go at a long constant run first. It costs nothing at all and frequently shifts the filter without assistance. - A drive will not shift it now — limp mode means that window has already shut. - A diesel smell in there, or black smoke under acceleration, is the point to stop booking long drives and call. ## The car has been warning you already By the time the light appears, things have normally been slipping for a while. It is belated news: - less power, particularly going uphill - revs that will not rise the way they used to - fuel consumption getting worse - without a word, the stop/start packs in - smoke under acceleration, or a diesel smell in there Any one of those, taken singly, is not conclusive. With the light with them, the filter is a fair bet. ## Choked diesel particulate filters near Fontwell, and the why Being a rural village, Fontwell throws up precisely the motoring a DPF handles worst. Run through a typical week: Slindon CofE Primary School and back, Fontwell Avenue at a halt before nine, a quick trip to Co-op Food, a dash to Barnham. Nothing there lasts long enough or gets hot enough to complete a regeneration. The unburnt soot builds up rather than clearing. The Waterlooville Bypass lies under 25 miles from Fontwell, Chichester under 10 miles off, and unless something takes you out that way routinely, whole weeks pass without the long steady run that empties a filter. Geography does not assist. ## Why limp mode stops a DPF regeneration It is self-preservation: that is all limp mode is. A sustained drive works by triggering a regeneration, and that is precisely what limp mode rules out: power capped, revs held down, no regeneration on offer. Sensible advice, that motorway run — until the point it is not. Once the motor is in limp mode you are beyond that stage, and the filter requires cleaning rather than driving. ## The motor stays put for on-site DPF cleaning round Fontwell Most people do not anticipate this detail: the filter stays on. The job happens with the DPF even now fixed to the car — on your front, in a work car park, wherever the car can sit for a couple of hours. A diagnostic goes 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 hardware, so other faults are cleared before anything is cleaned. Soot and ash that a regeneration on its own will never move are loosened after that, by a cleaning fluid passed through the access port on that motor, which opens out inside the filter. Where the filter is badly blocked, plan on a second pass. A regeneration follows, clearing what the clean has lifted. Either it runs as a monitored drive out of Fontwell, with you there, or it goes where the motor sits and the live data is read after. A second scan proves the change, clears the warning light and lists anything still open. Both sets of figures are emailed over, so you end up with the before and after figures recorded. ## What a DPF clean will not fix Treatment fixes one thing: a filter clogged with soot and ash. It does no good for: - a pressure or temperature sensor reporting a restriction that is not there - EGR valves that hang open - the AdBlue system going wrong - a regeneration that simply never starts, because of glow plugs or injectors - a turbo putting oil through the filter That is what the first diagnostic is for. When it turns out to be one of those, you are warned before any work gets going rather than after you have handed over a penny. DPF renewal is what people type in, but no part is exchanged: the filter you already own is cleaned where it sits and sent back into service. Nor is having it cut out a solution, since the MOT then fails and driving becomes unlawful. Two more things worth noting. ## What DPF cleaning comes to around Fontwell Any visit carries a call-out charge — travelling to you, setting up the booking, running the diagnostic and giving the advice. The clean itself begins from £299. Once we know what you own, and broadly what the filter will want, the figure gets fixed over phone. A single price for all would not be honest. Where you are tells as much as what you drive: Fontwell itself, Little Heath close by, or further out within the BN postcode area. A clean that will not work is not treatment you pay for, and the scan is what says so. You nonetheless pay that charge: someone travelled, carried out the check and passed on you the advice. If the light reappears inside that window, an engineer comes back out to Fontwell — the clean includes a 30-day warranty taking in aftercare. ## The vehicles we clean and the patch we cover around Fontwell The filter is cleaned in place on all of them: cars, panel vans and light commercials, HGVs and lorries, construction and plant machinery, agricultural vehicles. Nothing is moved anywhere. Week in week out there is usually someone on Fontwell Avenue, so Fontwell rarely means a detour, and Little Heath, Eastergate and the spots past Slindon are on the way. It is the calendar, not the distance, that settles whether it is this day or the next, and coverage extends UK-wide — so ring even from even further out through West Sussex. ## Fontwell itself Fontwell is a small village in West Sussex, situated inland near the South Downs and approximately 5.7 miles from Chichester. Fontwell sits at a relatively low elevation of around 25 metres, surrounded by nearby places such as Little Heath and Slindon. Fontwell has a population of around 505 people, predominantly living in detached houses. Fontwell is also located about 50.4 miles from London, making it a rural community within commuting distance of the capital. ## What Fontwell drivers ask about DPF cleaning Can I just take it for a long drive? If you get it early, and the vehicle is not in limp mode, sometimes. That requires motorway speed for a steady stretch, rather than a brief trip to Co-op Food. The visit lasts how long? Plan on typically around 2 hours — heavily blocked filters sometimes require a second pass, which lengthens it. In Fontwell, what does it come to? It starts from £299, plus the call-out charge taking in the visit, the check and the advice. Both the vehicle and where you are change it, which is why quoting goes by phone. Is it necessary for me to be there? Somewhere for the motor to sit, for a couple of hours, is all that is wanted. Not you. If you would sooner come along, the regeneration can be run as a watched drive instead. When can someone come to Fontwell? Depending on the diary, often same-day or next-day is normal. One call to 0303 330 1830 and you will learn what the BN area has free. Is the filter removed from the vehicle? It is done where it sits, on the call-out service. Neither job — a filter off, a filter back on — is not something we do. And if the light returns? Aftercare comes inside the 30-day warranty, and that includes an engineer coming back to Fontwell. ## Setting up a DPF clean across Fontwell Whatever it is doing — light, limp mode, smoke — say so when you call 0303 330 1830.
