An engineer comes at your place in Polmear, clears the diesel particulate filter while it is attached to the car, runs a DPF regeneration, and you end up with the filter you came with. Allow for the visit running typically around 2 hours. The clean begins from £299, settled by the phone before anyone sets off. The light is already on and the motor is short of power — that is how we generally meet people, and what this page covers. ## The DPF light is on. What next? Not the unit, automatically. Main thing to say. A scan happens before the work, because that same panel light has several possible faults behind it. Second thing: how you run it between now and then counts. - Vehicle yet driving normally on an amber light — attempt a long steady run first. It costs zero and regularly clears the filter without a visit. - Car already gone into limp mode — that window has closed. A drive will not shift it now. - Get it looked at rather than using it — diesel in the cabin, or smoke on the throttle, has gone beyond the long-run stage. ## The motor has been showing you already Symptoms have generally been mounting for a while before the light so much as shows. Belated news, in other words: - falling off on power, particularly uphill - the revs no longer rise the way they always did - fuel economy going worse - stop/start silently packing in - smoke under hard acceleration, or a diesel smell in the car On its own, none of that is proof. The light with them points at a full filter. ## Clogged diesel particulate filters round Polmear, and the cause Being a rural hamlet, Polmear produces exactly the use a DPF copes with the poorest. A regeneration wants the time and heat, and gets neither: not on the school run to Tywardreath School, not on Polmear Hill at half past eight, not on a few minutes to Co-op Food, and not on the hop to Par. The soot that should burn off builds up instead. The M5 stands over 50 miles from Polmear, Truro under 25 miles away, and unless something pulls you out that way regularly, full weeks slip past without the sustained run that clears a filter. Geography does not assist. ## The moment a DPF regeneration can no longer run It is self-defence: that is all limp mode is. With pulling power held down and the revs kept low, the regeneration the filter requires will not happen at all. That counts, because starting one is just what a sustained run does. The standard advice — get it up the motorway — is sound, until it is not. Once the motor is in limp mode you are the far side of that stage, and the filter requires treatment rather than road work. ## Where the vehicle stands is where the DPF is cleaned in Polmear Nothing comes off the motor. That throws people. The DPF remains bolted where it is and the work is done around it, on a forecourt, in a works car park, any place it can sit for a few hours. First a check. Real-time ECU data, the soot load as a percent and as a weight, the sensor readings, the glow plugs, the connected hardware — all of it taken before a thing is touched. Soot and ash that a regeneration by itself will never move are loosened next, by a cleaning fluid fed through the access port on that car, which opens out inside the filter. Sometimes a filter is clogged enough to require doing twice. A regeneration is next, driving off what the clean has loosened. Either it is done as a monitored drive out of Polmear, with you along, or it runs where the vehicle stands and the real-time data is read after. A second check proves the change, puts out the warning light and lists anything still outstanding. Both read-outs are sent over, so you keep the before and after figures on record. ## When a DPF clean is not the answer A filter choked with soot and ash is the one thing cleaning answers. It will not touch: - the wrong signal from a temperature sensor - EGR valves that hang open - the AdBlue system playing up - injectors or glow plugs that prevent a regeneration running at all - oil passing through the filter from a worn turbo Finding that out is the first scan's purpose. Proving to be one of them means finding out it before the work starts, not after handing over a penny. Two things more worth knowing. Leaving the filter cut out is not a remedy — a vehicle without a serviceable DPF fails its MOT and driving it is against the law. And cleaning is sometimes looked up as DPF renewal: nothing is replaced, your original filter is cleared in place and sent back into use. ## Figures for DPF cleaning across Polmear The cleaning starts from £299. A call-out charge covers every visit, and pays for the call-out itself, the booking, the scan and the advice that comes with it. Once we know what you drive, and roughly what the filter will need, the figure gets settled by phone. A single price for all would not be straight. The motor moves it, and so does the address — Polmear, Kilhallon, or a spot further out in the PL postcode area. Where the check says a clean will not help, you are not charged for treatment. The call-out charge still holds, because the visit, the scan and the advice have taken place. A 30-day warranty takes in aftercare on the work, and that includes an engineer travelling back out to Polmear if the light reappears inside the window. ## What we clean, and how far we go around Polmear Whatever it is — car, panel van, light commercial, heavy goods vehicle, plant, construction machinery, farm vehicle — the very same mobile service applies, and the filter never leaves it. Engineers are along Polmear Hill week in week out, so Polmear is seldom a special trip, and the same run picks up Kilhallon, Castledore and the villages out past Par. Coverage reaches UK-wide, so farther out around Cornwall is nonetheless worth a call, and what picks between today and tomorrow is the schedule rather than the distance. ## The ground around Polmear Polmear is a small coastal hamlet in Cornwall, situated near the towns of Par and Tywardreath, and close to the village of Polkerris. Polmear lies at a low elevation of around 3 metres, reflecting its coastal setting. Polmear has a population of approximately 294 people, living in predominantly detached housing. Polmear is located within commuting distance of Truro, the nearest city, which is around 17 miles away. ## Things Polmear drivers ask about DPF cleaning Will a long drive shift it? If you get it in time, and the car is not in limp mode, sometimes. That calls for motorway speed for a steady spell, rather than a short trip to Co-op Food. Roughly how long does it take? Expect typically around 2 hours — heavily loaded filters sometimes need a second pass, which extends it. How much does it run to across Polmear? The call-out charge takes in the visit, the check and the advice; the clean itself starts from £299. Both the vehicle and where you are change it, which is why settling it is done by phone. Must I be present in person? A spot for the motor to wait, for a couple of hours, is all that is required. Not you. The regeneration can be run as a monitored drive if you would rather ride along. Coming to Polmear — how soon? It is often same-day or next-day, depending on what is now in the diary. Phone 0303 330 1830 and you will hear what is open across the PL area. Is the filter taken off the vehicle? On the call-out service, no: the filter is cleaned in place. That work — a filter off, a filter back on — is not a job we do. Suppose the light comes back? Taken in by the 30-day warranty: aftercare, and an engineer travelling back to Polmear. ## Put a DPF clean booked around Polmear Whichever it is doing — light, limp mode, smoke — tell us so when you call 0303 330 1830.
