A fitter comes at your door across Ashton, cleans the diesel particulate filter while it is still on the vehicle, runs a DPF regeneration, and you end up with the filter you arrived with. The visit takes typically around 2 hours, the clean starts from £299, and the number is settled on the phone before anyone leaves. The light is already on and the motor is low on power — that is how we usually meet people, and precisely what this page deals with. ## What to check when the DPF light shows First thing: it is not automatically the unit. A scan comes before all work, because that same dash light has several candidate faults behind it. The motoring you do in the meantime counts. That is the second thing. - A long constant run may still do it, provided the light is amber and the car runs fine. Costs zero, so try that before ringing. - Motor already dropped into limp mode — that window has closed. A drive will not touch it now. - Diesel smell in the car, or black smoke under hard acceleration — stop booking long drives and get it looked at. ## The vehicle has been warning you already Last news, the light. The symptoms generally grow for some time before it appears: - power dropping away, especially going uphill - the revs no longer pull the way they once did - worse fuel use - a stop/start that has silently packed in - diesel in the car, or smoke on the way up through the gearbox Alone, none of that is conclusive. Alongside the light with them, the filter is a fair assumption. ## Why diesel particulate filters block around Ashton Being a rural hamlet, Ashton generates exactly the driving a DPF manages the poorest. A regeneration needs long enough and heat, and gets none: not on the school run to St Dominic CofE Primary School, not on A388 at half eight, not on ten minutes to Tesco, and not on the run to Gunnislake. The soot that should burn away banks up instead. The M5 lies under 50 miles from Ashton, Plymouth under 15 miles out, and unless something takes you out that way often, entire weeks go by without the long unbroken run that scours a unit. Geography does not assist. ## DPF regeneration, and the stage limp mode stops it It is self-preservation: that is all limp mode amounts to. A sustained drive works by triggering a regeneration, and that is precisely what limp mode blocks: power limited, revs pinned, no regeneration available. So the standard advice to run it up the motorway is sound advice, up until the day it is not. Beyond that stage — limp mode — driving will not manage it, and the filter needs treatment. ## Call-out DPF cleaning where the motor stands across Ashton Nothing comes off the motor. That catches out people. The DPF stays fixed where it is and the work goes on around it, on a driveway, in a works car park, anywhere it can wait for a few hours. The ECU is read first, giving soot load by percent and by mass, along with a check of sensor feeds, glow plugs and related components, so nothing is started while another fault is still in play. After that comes the clean itself: solution in through the car's own access point, spreading inside the filter and lifting what a regeneration will not. Where the filter is badly loaded, allow for a second pass. What the clean has loosened is then cleared by a regeneration. Either it runs as a monitored drive out of Ashton, with you present, or it goes where the vehicle stands and the live data is read once done. Finally the check runs again — the change proven, the light put out, anything still outstanding written down. Both reports reach you by email, so the numbers are on record. ## The faults a DPF clean cannot answer Cleaning answers one thing: a filter clogged with soot and ash. It does little for: - a pressure sensor reporting a restriction that is not there - EGR valves that stick open - the AdBlue system playing up - worn glow plugs or injectors, so never a regeneration ever starts - the turbo passing oil into the filter That is what the first diagnostic is for. When it proves to be one of those, you are let know before any work begins rather than after you have paid a penny. Hollowing the filter out is not a remedy: without a functioning DPF a vehicle will fail its MOT, and driving it is against the law. DPF renewal is the wording people search for, though nothing is exchanged — your original filter is cleared in place and returned into use. Two more worth bearing in mind. ## Prices for DPF cleaning across Ashton Any visit attracts a call-out charge — getting to you, taking the booking, doing the check and giving the advice. The clean itself opens from £299. Once we know what you drive, and about what the filter will want, the figure gets agreed by phone. A single price for everyone would not be straight. What you run and where you are both move it: Ashton itself, across at Cross, or otherwise out across the PL postcode area. Cleaning that will not work is not cleaning you pay for, and the scan is what says so. What even so holds is the call-out charge, since the visit was made, the diagnostic was carried out and the advice was given. The job comes with a 30-day warranty including aftercare, including an engineer heading back out to Ashton if the light returns inside that time. ## Vehicles we clean, and where we get to around Ashton Whatever it is — estate, light van, light commercial, lorry, plant, construction machinery, agricultural vehicle — the very same mobile service applies, and the filter never quits it. The same round that keeps our engineers on A388 most weeks picks up Ashton, Cross, Rising Sun and the villages beyond St Dominick. It is the schedule, not the distance, that picks whether it is today or tomorrow, and coverage reaches UK-wide — so ring still from farther out across Cornwall. ## About Ashton Ashton is a small hamlet in inland Cornwall, situated at an elevation of 137 metres and comprising predominantly detached housing.

Sometimes, if you get it early enough and the motor has not dropped into limp mode. It needs a long run at motorway speed, not fifteen minutes or so to Tesco and back. The visit lasts how long? Expect typically around 2 hours — heavily clogged filters sometimes require a second pass, which adds to it. What does it run to around Ashton? The call-out charge covers the visit, the scan and the advice; cleaning itself begins from £299. Pricing is done by phone, since what you own and where you are both change the figure. Is it needed for me to be there? The car requires a place for two hours or so. You need not be in it. Choosing to be there is welcome: the regeneration then is done out on the road, monitored.
