No body shop, no filter going anywhere. An engineer travels to your address over in Trescowe, cleans the diesel particulate filter where it is, performs a DPF regeneration, and you hold on to the filter you started with. Reckon on the visit running typically around 2 hours. The clean begins from £299, settled over the phone before anyone sets off. The light is showing and the vehicle is down on power — that is how we generally come across people, and roughly what this page deals with. ## The DPF light is on. What now? It could not be the filter at all. That is the opening thing. A clean is not where a visit opens. A scan is — a number of faults register as the same warning. Second thing: how you drive it between now and then makes a difference. - A long even run may yet do it, provided the light is amber and the vehicle runs as normal. Costs nothing, so attempt that before booking. - Vehicle already fallen into limp mode — that window has shut. A drive will not shift it now. - Get it checked rather than using it — diesel in the cabin, or smoke on hard acceleration, has gone beyond the long-run stage. ## The vehicle has been telling you already The light is belated news. By the time it appears, the symptoms have normally been mounting for some time: - power falling off, especially pulling uphill - you find the revs fall short of where they once went - fuel economy going worse - stop/start quietly packing in - a diesel smell in the cabin, or smoke under hard acceleration None of that is conclusive by itself. With the light alongside them, the filter is a fair bet. ## The cause diesel particulate filters choke near Trescowe For a DPF, the worst motoring is the sort you get around a rural hamlet such as Trescowe. A regeneration wants long enough and heat, and sees not much: not on the school run to Germoe Community Primary School, not on Trewithen Terrace at half past eight, not on a few minutes to Asda, and not on the dash to St Erth. Instead of burning away, the soot load builds up. Neither is far from Trescowe: over 50 miles to the M5, under 25 miles to Truro. Neither is on the way to anywhere most weeks, though, so the journey that would scour a filter hardly ever happens. ## Limp mode, and when DPF regeneration stops working The vehicle is looking after itself, which is what limp mode amounts to. A sustained drive works by starting a regeneration, and that is just what limp mode rules out: power limited, revs kept low, no regeneration on offer. The usual advice — get it up the motorway — is good, up until it is not. In limp mode you are past that line: a clean is what will help, not more road work. ## DPF cleaning at the motor across Trescowe Nothing comes off the motor. That throws people. The DPF stays bolted where it is and the work happens around it, on a driveway, in a works car park, any place it can stand for two hours or so. The ECU is interrogated first, showing soot load by percentage and by weight, along with a review of sensor readings, glow plugs and related components, so nothing is started while another fault is still open. Then the clean. A cleaning solution is injected through the access point on that vehicle and opens out inside the filter, lifting the soot and ash a regeneration by itself will never shift. A second pass is sometimes required on severely clogged filters. Then a regeneration, to clear what the clean has loosened. If you are there, that is done as a monitored drive out of Trescowe; if not, in place where the car stands, with the real-time data checked after. Finally the check runs again — the change proven, the light put out, anything still outstanding logged. Both reports come to you by email, so the numbers are kept. ## The faults a DPF clean cannot fix Cleaning fixes one thing: a filter choked with soot and ash. It does little for: - the wrong figure from a temperature sensor - the EGR valve held open - a fault in the AdBlue system - injectors or glow plugs that prevent a regeneration running in the first place - turbo failure, with oil reaching the filter That is what the first scan is for. You are told before any work begins, not after you have handed over, should it turns out to be one of those. Lastly, two things. A vehicle with the filter cut out will fail its MOT, and driving it is illegal, so that is no solution. What gets looked up as DPF renewal exchanges nothing: your filter is cleaned in place and goes back into service. ## The figure for DPF cleaning around Trescowe A call-out charge holds whatever happens, and pays for the visit, the booking fee, the check and the advice offered. Treatment itself starts from £299. Naming a flat rate would not be honest. We agree it on the phone, once the car and its expected needs are known. Where you are tells as much as what you drive: Trescowe itself, Relubbus close by, or further out across the TR postcode area. You are not charged for treatment that the scan says will not help. Because the visit, the diagnostic and the advice have taken place, the call-out charge still applies. If the light reappears inside that time, an engineer comes back out to Trescowe — the job includes a 30-day warranty including aftercare. ## Where we reach round Trescowe, and what we clean The one call-out service spans cars, vans of any size and light commercials, HGVs and lorries, plant and construction machinery and farm vehicles, and on every one the filter is cleaned where it sits rather than moved anywhere. Trescowe is rarely a special trip: engineers are out on Trewithen Terrace nearly every week, and the same run picks up Relubbus, Great Work and the spots out past Germoe. Phone anyway from further out across Cornwall. Coverage runs UK-wide, and the day you are given depends on the calendar rather than how far away you are. ## A word on Trescowe Trescowe is a small coastal hamlet in Cornwall, situated near the towns of Millpool and Halamanning, with Trescowe being one of the many scattered settlements in this part of the South West.

If you get it early, and the car is not in limp mode, sometimes. It needs a long run at motorway speed, not ten minutes to Asda and back. The visit lasts how long? Expect typically around 2 hours — severely loaded filters sometimes take a second pass, which lengthens it. How much does it come to in Trescowe? Opening from £299, with a charge for the call-out that pays for the check and advice on what to do next. We quote on the phone, because the vehicle and your address both shift the figure. Is it necessary for me to be there? Space for the vehicle to sit, for a couple of hours, is all that is wanted. Not you. The regeneration can be run as a supervised drive if you would prefer to come along. Coming to Trescowe — how soon? Depending on the calendar, often same-day or next-day is typical. One ring to 0303 330 1830 and you will learn what the TR area has open. The filter — does it come off the vehicle? Not on the call-out service — it is done where it is. Getting a filter off or bolting one back on count as anything work we do either way. The light reappears — then what? An engineer travels back out to Trescowe — the 30-day warranty takes in aftercare. ## Book a DPF clean in Trescowe Whichever it is doing — light, limp mode, smoke — tell us so when you ring 0303 330 1830.
