The fitter pulls up at your address in Porkellis 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 started with. You'll be given a price by phone before anyone departs, the clean opening from £299, and the visit lasting typically around 2 hours. Most people find us with the light already on, and the motor low on power. That is the position this page is written for. ## Your DPF light is lit — what next? First thing: it is not necessarily the filter. A scan happens before the treatment, because that same dash light has several candidate faults behind it. How the car is driven in the meantime matters too. - Amber light, vehicle even now driving as normal — a long constant run can even now sort it by itself. Costs nothing at all, and worth attempting before you call anything. - Motor already gone into limp mode — that window has closed. A drive will not reach it now. - A diesel smell in the car, or black smoke under hard acceleration, is the moment to stop booking long drives and book it in. ## Before the light, what the motor was warning you Symptoms have normally been growing for some time before the light so much as appears. Last news, in other words: - less power, particularly pulling uphill - revs that will not climb the way they once did - the fuel economy is poorer - a stop/start that has meekly packed in - the car smelling of diesel, or smoke when you accelerate None of that is proof alone. Alongside the light, it is a fair bet the filter is blocked. ## Choked diesel particulate filters near Porkellis, and the cause For a DPF, the least kind use is the kind you find in a village such as Porkellis. The school run to Halwin School, Halwin Lane at a standstill at half eight, a few minutes to Tesco, the run to Camborne — none of it runs long enough or runs hot enough for the filter to see through a regeneration. Instead of clearing, the soot load builds up. Unless you have a routine need to drive out to the M5, over 50 miles from Porkellis, or across to Truro under 15 miles away, whole weeks pass without a long steady stint. Geography is unhelpful. ## Limp mode, and when DPF regeneration gives out Limp mode is the car defending itself. A long drive works by setting off a regeneration, and that is precisely what limp mode blocks: power limited, revs held down, no regeneration possible. The standard advice — take it up the motorway — is sound, up until it is not. In limp mode you are past that line: treatment is what will help, not more driving. ## DPF cleaning at the motor across Porkellis Nothing leaves the vehicle. That catches out people. The DPF remains fitted where it is and the work goes on around it, on a driveway, in a works car park, any place it can stand for a couple of hours. First a check. Running ECU data, the soot load as a percent and as a weight, the sensor readings, the glow plugs, the connected components — all of it read before any of it is touched. A solution then goes in through the access port on that motor, expanding inside the filter to loosen soot and ash a regeneration alone will never shift. A second pass is sometimes needed on badly blocked filters. Next, a regeneration drives off everything the clean freed. If you are there, that is carried out as a monitored drive out of Porkellis; if not, in place where the car sits, with the real-time data read once done. Both reports go over by email, so the figures from either end are kept. The second diagnostic is what proves the change, resets the light and logs whatever is still showing. ## What a DPF clean will not fix A clean fixes one thing: a filter choked with soot and ash. It does no good for: - the wrong reading from a pressure or temperature sensor - a stuck-open EGR valve - a failure in the AdBlue system - injectors or glow plugs that stop a regeneration completing in the first place - a turbo putting oil through the filter Finding that out is the first diagnostic's job. Proving to be one of them means finding out it before the work starts, not after paying a penny. DPF renewal is what people look up, but no part is exchanged: the filter you already own is cleared where it sits and put back to work. Nor is having it hollowed out a solution, since the MOT then fails and driving becomes unlawful. Two more things worth bearing in mind. ## What DPF cleaning costs in Porkellis Every visit attracts a call-out charge — getting to you, making the booking, running the diagnostic and passing on the advice. The clean itself starts from £299. Publishing a flat rate would not be straight. We settle it on the phone, once the car and its likely needs are known. The motor changes it, and so does the postcode — Porkellis, Lezerea, or somewhere further out in the TR postcode area. Treatment that will not do it is not treatment you pay for, and the diagnostic is what says so. You even so pay that charge: someone turned up, carried out the diagnostic and gave you the advice. Aftercare is taken in by a 30-day warranty: should the light reappear within it, an engineer returns to Porkellis. ## What we clean, and how far we reach round Porkellis Whatever it is — car, panel van, light commercial, heavy goods vehicle, plant, construction machinery, agricultural vehicle — the very same on-site service stands, and the filter never departs it. Engineers are along Halwin Lane most weeks, so Porkellis is hardly ever a special trip, and the same run picks up Lezerea, Halwin and the spots out past Penmarth. Coverage reaches UK-wide, so even further out through Cornwall is nonetheless worth a call, and what decides between today and tomorrow is the schedule rather than the distance. ## About Porkellis Porkellis is a small village in Cornwall, situated near the riverside and surrounded by rolling hills, with Lezerea, Halwin, and Boswin nearby.

If you catch it in time, and the motor is not in limp mode, sometimes. It takes a sustained run at motorway speed, not five minutes or so to Tesco and back. The visit lasts how long? It is typically around 2 hours. A severely blocked filter can need a second clean, which adds to that. Price in Porkellis — what is it? A clean starts from £299, and the call-out charge on top pays for the visit, the diagnostic and the advice. Both the vehicle and where you are move it, which is why settling it goes by phone. Do I have to be around? You need not stand with it — the motor simply needs somewhere to stand for a couple of hours. If you would rather come along, the regeneration can be carried out as a supervised drive instead. Can someone come to Porkellis soon? That hangs on the calendar, but it is often same-day or next-day. Phone 0303 330 1830 and we will let you what is open across the TR area. Will the filter be removed? Not on the on-site service — it is done where it sits. We do not lift filters off or fit them back on, in either direction. What if the light reappears? An engineer comes back out to Porkellis — the 30-day warranty includes aftercare. ## Book a DPF clean across Porkellis Tell us round what the motor is doing on 0303 330 1830, whether that is smoke, limp mode or the light.
