The fitter pulls up at your place over in Pencuke and gets to work. The diesel particulate filter is cleaned on the motor, a DPF regeneration comes next, and you end up with the filter you arrived with. You'll know a number by phone before anyone goes, the clean starting from £299, and the visit running typically around 2 hours. The light is showing and the vehicle is low on power — that is how we generally find people, and precisely what this page deals with. ## Your DPF light is showing — what now? Not the filter, automatically. Opening thing to note. A check happens before all cleaning, because that same panel light has plenty of possible faults behind it. How the vehicle is handled in the meantime makes a difference too. - Amber light, motor still driving as normal — a long even run can yet sort it alone. Costs nothing at all, and worth attempting before you ring anything. - That window has shut once the motor has dropped into limp mode. A drive will not help now. - Get it seen to rather than driving it — diesel in the interior, or smoke on hard acceleration, has gone beyond the long-run stage. ## Before the light, what the motor was warning you By the time the light appears, things have usually been going wrong for some time. It is belated news: - power falling off, above all going uphill - you notice the revs fall short of where they used to go - fuel economy going worse - stop/start quietly packing in - diesel in the cabin, or smoke on the way up through the gears Any one of those, taken by itself, is not proof. It is a fair assumption the filter is loaded once the light is on as well. ## Why diesel particulate filters clog near Pencuke Being a rural hamlet, Pencuke throws up precisely the motoring a DPF copes with the poorest. The school run to Otterham Community Primary School, B3263 at a halt at half eight, a few minutes to Spar, the run to the nearest station — not one bit of it goes on long enough or runs hot enough for the filter to see through a regeneration. Instead of burning off, the soot load builds up. Neither is distant from Pencuke: under 50 miles to the M5, under 50 miles to Plymouth. Neither is on the way to anywhere most weeks, though, so the drive that would empty a filter simply never happens. ## The moment a DPF regeneration can no longer happen Limp mode is the vehicle looking after itself. A long drive works by setting off a regeneration, and that is exactly what limp mode blocks: power limited, revs pinned, no regeneration available. So the usual advice to run it up the motorway is sound advice, up until the day it is not. In limp mode you are past that line: treatment is what will work, not more road work. ## Where the car stands is where the DPF is treated in Pencuke Most drivers do not see coming this bit: the filter stays on. The job happens with the DPF yet bolted to the motor — on your front, in a work car park, any place the car can wait for a while. First a diagnostic. Running ECU data, the soot load as a proportion and as a figure, the sensor feeds, the glow plugs, the connected components — all of it read before anything is touched. A cleaning solution after that goes in through the entry point on that motor, opening out inside the filter to free soot and ash a regeneration by itself will never shift. Where the filter is heavily blocked, plan on a second pass. A regeneration follows, burning off what the clean has freed. If you are there, that is run as a monitored drive out of Pencuke; if not, on the spot where the motor waits, with the running data checked afterwards. A second scan confirms the change, puts out the warning light and notes anything still outstanding. Both read-outs are sent over, so you end up with the before and after figures on record. ## The problems a DPF clean cannot cure One thing is what a clean answers — a filter choked with soot and ash. It does little for: - pressure or temperature sensors flagging a restriction that is not there - a failed EGR valve - a problem in the AdBlue system - a regeneration that hardly ever starts, because of glow plugs or injectors - turbo failure, with oil entering the filter Which is why the scan goes first. You are let know before the work begins, not after you have paid, should it turns out to be one of those. A couple more worth bearing in mind. Leaving the filter cut out is not a remedy — a vehicle without a functioning DPF cannot pass its MOT and driving it is against the law. And cleaning is sometimes searched for as DPF renewal: nothing is swapped, your original filter is treated in place and returned into use. ## DPF cleaning prices in Pencuke A call-out charge stands whatever happens, and covers the visit, the booking fee, the check and the advice given. Cleaning itself starts from £299. Quoting a flat rate would not be straight. We settle it by phone, once the car and its expected needs are established. What you run and where you are both shift it: Pencuke itself, over at Higher Crackington, or farther out within the EX postcode area. Where the check says treatment will not help, you are not asked to pay for a clean. What nonetheless applies is the call-out charge, since the visit happened, the check was done and the advice was given. Aftercare is taken in by a 30-day warranty: should the light come back within it, an engineer returns to Pencuke. ## Where we reach around Pencuke, and what we clean Whatever it is — private car, van, light commercial, lorry, plant, construction machinery, agricultural machine — the same on-site service stands, and the filter never quits it. The same trip that keeps our engineers on B3263 most weeks covers Pencuke, Higher Crackington, Lower Crackington and the villages beyond Middle Crackington. Call anyway from even further out across Cornwall. Coverage extends UK-wide, and the date you are offered comes down to the schedule rather than how far away you are. ## About Pencuke Pencuke is a small coastal hamlet in Cornwall, situated near the villages of Higher Crackington and Lower Crackington.

Sometimes, if you get it early and the motor has not slipped into limp mode. A long run at motorway speed is what it takes — not five minutes or so to Spar and back. Broadly how long does it take? Bank on typically around 2 hours, with a second clean extending that where the filter is heavily blocked. How much does it run to in Pencuke? The call-out charge takes in the visit, the diagnostic and the advice; cleaning itself begins from £299. Pricing is done by phone, since what you drive and where you sit both change the figure. Do I have to be present? No. The vehicle requires a spot to wait for a couple of hours; you need not stand with it. The regeneration can be done as a watched drive if you would rather be there. When can someone travel to Pencuke? That depends on the calendar, but it is often same-day or next-day. Phone 0303 330 1830 and you will learn what is available across the EX area. Does the filter come away from the car? On the on-site service, no: the filter is cleaned in place. Neither job — a filter off, a filter back on — is not something we do. Suppose the light returns? Aftercare comes inside the 30-day warranty, and that includes an engineer coming back to Pencuke. ## Arrange DPF cleaning in Pencuke Phone 0303 330 1830 and set out what the car is doing: light, limp mode, smoke, whatever it is.
