Your car is not taken away and the filter will not come off. An engineer arrives at your place across Come-to-Good, cleans the diesel particulate filter fitted to the car and runs a DPF regeneration. Allow for the visit running typically around 2 hours. The clean begins from £299, settled on the phone before anyone sets off. The light is showing and the vehicle is short of power — that is how we normally find people, and roughly what this page deals with. ## Your DPF light is lit — what next? First thing: it is not automatically the unit. Plenty of faults put the same light on the very same dashboard, which is why a visit begins with a check rather than with treatment. It matters what you do with the motor between now and the visit. - Amber light, car even now driving fine — a long even run can still sort it on its own. Costs nothing, and worth a try before you call anything. - Car already gone into limp mode — that window has closed. A drive will not reach it now. - Diesel smell in the interior, or black smoke under acceleration — stop arranging long drives and get it seen to. ## What the motor has been telling you Symptoms have normally been building for some time before the light ever appears. Belated news, in other words: - less power, particularly climbing uphill - you see the revs fall short of where they once went - consumption that is worse than before - a stop/start that has meekly bowed out - smoke under acceleration, or a diesel smell in the car Any one of those, taken by itself, is not evidence. With the light with them, the filter is a fair assumption. ## What chokes diesel particulate filters around Come-to-Good Come-to-Good is a coastal area, and the driving that belongs to one is the poorest type for a DPF. A regeneration needs long enough and heat, and sees none: not on the school run to Kea Community Primary School, not on B3289 at half past eight, not on five minutes to Lidl, and not on the dash to Perranwell. The unburnt soot banks up rather than burning away. The M5 lies over 50 miles from Come-to-Good, Truro under 3 miles out, and unless something carries you out that way often, full weeks pass without the sustained run that clears a filter. Geography does not oblige. ## Why limp mode prevents a DPF regeneration What limp mode means is the car defending itself. The real catch is that a long drive works by setting off a regeneration, and under limp mode the revs will not rise and power is limited. The common advice — get it up the motorway — is good, right until it is not. Once the car is in limp mode you are past that line, and the filter wants cleaning rather than more driving. ## Where the car stands is where the DPF is treated in Come-to-Good Most drivers do not anticipate this bit: the filter stays put. The job takes place with the DPF even now bolted to the car — on your driveway, in a work car park, any place the car can sit for a few hours. A check comes first — running data off the ECU, soot load by percentage and by mass, and a review of the sensor readings, glow plugs and related parts, so other faults are cleared before anything is touched. Then comes the clean itself: solution in through the car's own entry point, spreading inside the filter and freeing what a regeneration will not. Where the filter is heavily clogged, expect a second pass. Then a regeneration, to clear what the clean has loosened. If you are there, that is run as a monitored drive out of Come-to-Good; if not, in place where the vehicle stands, with the live data checked once done. Both reports are sent by email, so the figures from either end are recorded. The second diagnostic is what proves the change, resets the light and lists whatever is still open. ## Where cleaning is not the solution A filter blocked with soot and ash is the one thing cleaning cures. It will not help: - the wrong signal from a temperature sensor - the EGR valve held open - an AdBlue system problem - a regeneration that never runs, because of glow plugs or injectors - the turbo putting oil into the filter Which is why the diagnostic happens first. You are warned before all work begins, not after you have paid, where it turns out to be one of those. Lastly, two things. A vehicle with the filter gutted fails its MOT, and driving it is against the law, so that is no remedy. What gets looked up as DPF renewal replaces nothing: your existing filter is cleared in place and goes back into service. ## Figures for DPF cleaning in Come-to-Good Treatment starts from £299, with the call-out charge on top of that for every visit — it covers the call-out, the booking, the checks and the advice. Once we have what you drive, and roughly what the filter will want, the number gets fixed over phone. A single price for everyone would not be honest. Whereabouts you are matters as much as what you drive: Come-to-Good itself, Penelewey close by, or otherwise out across the TR postcode area. You are not charged for a clean that the scan says will not do it. Because the visit, the scan and the advice have been done, the call-out charge nonetheless stands. The work comes with a 30-day warranty taking in aftercare, including an engineer coming back out to Come-to-Good if the light reappears inside that window. ## Vehicles we clean, and where we travel near Come-to-Good Whatever it is — car, van, light commercial, HGV, plant, construction machinery, farm vehicle — the one call-out service stands, and the filter never leaves it. The same round that puts engineers on B3289 most weeks takes in Come-to-Good, Penelewey, Playing Place and the places beyond Carnon Downs. Farther out through Cornwall is even so worth a call — coverage is UK-wide, and it is the schedule rather than the distance that picks between one day and the next. ## About Come-to-Good Come-to-Good is a small coastal locality in Cornwall, situated near the city of Truro and overlooking the surrounding countryside from a height of around 83 metres. Come-to-Good consists mainly of detached housing and is close to nearby places such as Penelewey and Goonpiper. Come-to-Good has a population of approximately 321 residents, who live in a quiet area near the coast. ## Questions Come-to-Good drivers ask about DPF cleaning Does a long run clear it? Early enough, and with the car out of limp mode, yes — sometimes. Five minutes to Lidl and back will not be enough; motorway speed, sustained for some time, will. Roughly how long does it run? That is typically around 2 hours, though a heavily clogged filter can take cleaning twice, which adds time. What does it run to across Come-to-Good? The call-out charge takes in the visit, the scan and the advice; treatment itself opens from £299. Settling it is done by phone, since what you run and where you are both move the figure. Is it essential for me to be present? The car requires a space for two hours or so. You need not be in it. If you would rather come along, the regeneration can be run as a watched drive instead. When can someone come to Come-to-Good? It is often same-day or next-day, depending on what is now in the diary. Ring 0303 330 1830 and we will tell you what is available across the TR area. Will the filter be taken off? On the call-out service, no: the filter is treated in place. We will not take filters off or fit them back on, whichever way. Suppose the light returns? The 30-day warranty covers aftercare, including an engineer heading back to Come-to-Good. ## Booking a DPF clean in Come-to-Good Tell us about what the vehicle is doing on 0303 330 1830, whether that is smoke, limp mode or the light.
