No garage, no filter coming off. A fitter drives out to your door across Trevescan, clears the diesel particulate filter where it is, performs a DPF regeneration, and you end up with the filter you started with. The visit runs typically around 2 hours, the clean begins from £299, and the number is agreed by the phone before anyone sets off. Written for the position most owners are in: the light on already, the vehicle starved for power, and the job still to fix. ## Your DPF light is showing — what then? First thing: it is not automatically the unit. A check goes before the work, because that same dash light has several candidate faults behind it. Second thing: how you run it between now and then counts. - Worth a shot before you book anything: amber light, motor driving as normal, just one steady run, no cost. - Car already gone into limp mode — that window has shut. A drive will not touch it now. - Stop booking long drives and get it looked at if the cabin stinks of diesel or there is black smoke when you press on. ## The motor has been showing you already Late news, the light. The symptoms generally build for some time before it shows: - power falling off, especially pulling uphill - an engine whose revs will not rise as before - fuel economy turning worse - stop/start quietly giving up - the car smelling of diesel, or smoke when you accelerate By itself, none of that is evidence. Alongside the light, it is a fair assumption the filter is loaded. ## Blocked diesel particulate filters around Trevescan, and the why Being a rural hamlet, Trevescan throws up precisely the driving a DPF handles the poorest. A regeneration takes the time and heat, and gets none: not on the school run to Sennen Community Primary Academy, not on B3315 at half eight, not on ten minutes to Co-op Food, and not on the dash to Penzance. Unburnt soot that should burn off builds up instead. Except when you have a standing need to head out to the M5, over 50 miles from Trevescan, or out to Truro under 50 miles away, entire weeks pass without a long unbroken drive. Geography is against you. ## Limp mode, and when DPF regeneration stops The vehicle is looking after itself, which is what limp mode means. A sustained drive works by setting off a regeneration, and that is exactly what limp mode blocks: power capped, revs pinned, no regeneration available. The common advice — take it up the motorway — is sound, until it is not. The filter requires treatment rather than more driving once the motor has slipped into limp mode. ## Where the motor stands is where the DPF is done across Trevescan The filter does not leave it. That is the detail most drivers do not anticipate: the job is done with the DPF even now bolted to the car, on your driveway, in a work car park, anywhere the vehicle can sit for a couple of hours. Nothing is cleaned until other faults are eliminated. That involves a check first: real-time data off the ECU, soot load by proportion and by actual weight, and a check of the sensors, glow plugs and associated hardware. A cleaning fluid after that goes in through the access point on that motor, spreading inside the filter to lift soot and ash a regeneration on its own will never move. Sometimes a filter is blocked enough to take doing twice. What the clean has freed is then cleared by a regeneration. If you are there, that is carried out as a monitored drive out of Trevescan; if not, on the spot where the motor sits, with the running data verified after. A second diagnostic verifies the change, puts out the warning light and lists anything still outstanding. Both sets of figures are emailed, so you have the before and after figures recorded. ## When a DPF clean is not the solution A clean answers one thing: a filter blocked with soot and ash. It does nothing for: - sensors, pressure or temperature, reporting a restriction that is not real - the EGR valve stuck open - AdBlue system failures - worn glow plugs or injectors, so no regeneration ever completes - a turbo putting oil through the filter That is what the first diagnostic is for. You are warned before the work starts, not after you have settled up, if it turns out to be one of those. Two more worth knowing. Getting the filter gutted is not a fix — a vehicle without a serviceable DPF will fail its MOT and driving it is against the law. And cleaning is sometimes searched for as DPF renewal: nothing is swapped, your existing filter is cleared in place and returned into use. ## Prices for DPF cleaning across Trevescan Treatment starts 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. The figure is settled over the phone, once we are told the vehicle and what the filter is going to need. No flat rate could be honest. What you drive and where you are both change it: Trevescan itself, over at Trevilley, or further out in the TR postcode area. Where the scan says cleaning will not do it, you are not asked to pay for a clean. What even so stands is the call-out charge, since the visit took place, the diagnostic was done and the advice was passed on. A 30-day warranty covers aftercare on the work, and that includes an engineer travelling back out to Trevescan if the light reappears inside the time. ## What we clean, and how far we go round Trevescan The one call-out service spans cars, vans and light commercials, HGVs and lorries, plant and construction machinery and agricultural machinery, and on every one the filter is treated where it sits rather than moved anywhere. Our engineers are along B3315 nearly every week, so Trevescan is hardly ever a journey of its own, and the same run takes in Trevilley, Carn Towan and the villages out past Mayon. Further out around Cornwall is still worth phoning about — coverage runs UK-wide, and it is the calendar rather than the distance that settles between one day and the next. ## About Trevescan Trevescan is a small coastal hamlet in Cornwall, situated near the villages of Trevilley and Sennen, with Mayon also nearby. Trevescan sits at an elevation of 82 metres, overlooking the surrounding coastline. Trevescan is characterized by its predominantly detached housing stock, reflecting its rural and scattered nature. Trevescan is located approximately 31 miles from Truro, the nearest city, and around 263 miles from London. ## What Trevescan drivers ask about DPF cleaning Is a long drive enough on its own? Quickly enough, and with the car out of limp mode, yes — sometimes. Five minutes to Co-op Food and back will not do it; motorway speed, sustained for a stretch, will. About how long does it last? That is typically around 2 hours, though a badly loaded filter can take cleaning twice, which takes longer. How much does it run to in Trevescan? Starting from £299, with a charge for travelling that covers the scan and advice on what to do next. Settling it is done by phone, since what you run and where you live both move the figure. Do I have to be around? You need not stand with it — the motor only wants space to stand for a couple of hours. If you would prefer to come along, the regeneration can be run as a supervised drive instead. Can someone get to Trevescan soon? That depends on the diary, but it is often same-day or next-day. Call 0303 330 1830 and we will say to you what is available across the TR area. Will the filter be taken off? It is treated where it stands, on the mobile service. Taking a filter off or putting one back on come to anything a job we do either way. What if the light comes back? An engineer travels back out to Trevescan — the 30-day warranty includes aftercare. ## Put a DPF clean booked in Trevescan However it is doing — light, limp mode, smoke — say so when you ring 0303 330 1830.
