No workshop, no filter coming off. A technician travels to your place over in Higher Porthpean, clears the diesel particulate filter in place, runs a DPF regeneration, and you keep the filter you arrived with. The visit takes typically around 2 hours, the clean starts from £299, and the number is fixed over the phone before anyone leaves. The light is on already and the motor is short of power — that is how we generally come across people, and roughly what this page deals with. ## The DPF light is on. What now? The DPF is not always what is at fault, and that goes first. Treatment is not where a visit starts. A check is — plenty of faults show up as the same light. The motoring you manage in the meantime tells. That is the second thing. - Car still driving as normal on an amber light — attempt a long steady run first. It costs nothing at all and regularly clears the filter without a visit. - That window has closed once the vehicle has dropped into limp mode. Driving will not help now. - Get it checked rather than running it — diesel in the cabin, or smoke on the throttle, has gone past the long-run stage. ## The vehicle has been telling you already Symptoms have generally been mounting for a while before the light ever appears. Belated news, in other words: - dropping away on power, especially uphill - the revs no longer pull the way they once did - the fuel consumption is worse - the stop/start quietly packing in - diesel in the car, or smoke on the way up through the box That is not evidence alone. Next to the light with them, the filter is a fair assumption. ## Why diesel particulate filters clog round Higher Porthpean Higher Porthpean is a rural hamlet, and the driving that belongs to one is the worst sort for a DPF. A regeneration takes long enough and heat, and gets not much: not on the school run to Mount Charles School, not on Porthpean Road at the morning rush, not on ten minutes to Asda, and not on the run to St Austell. Instead of burning off, the unburnt soot banks up. Where you sit does not help either. The M5 is over 50 miles from Higher Porthpean and Truro is under 15 miles away, so unless something carries you out that way routinely, whole weeks pass without the sustained run that might scour the filter on its own. ## Limp mode, and when DPF regeneration stops working It is self-defence: that is all limp mode amounts to. A proper drive works by starting a regeneration, and that is just what limp mode prevents: power limited, revs kept low, no regeneration possible. Sound advice, that motorway run — right up until the day it is not. Once the car is in limp mode you are the far side of that point, and the filter requires cleaning rather than road work. ## Where the vehicle stands is where the DPF is cleaned across Higher Porthpean On your driveway, in a work car park, anywhere the motor can wait for a few hours: the job is done with the filter even now fitted on, which is the bit most owners do not see coming. Nothing is cleaned until other faults are eliminated. That requires a diagnostic first: running data off the ECU, soot load by percentage and by mass, and a review of the sensors, glow plugs and connected components. Then the treatment. A cleaning solution is injected through the entry point on that vehicle and expands inside the filter, loosening the soot and ash a regeneration by itself will never budge. Sometimes a filter is clogged enough to take doing twice. What the clean has loosened is then burned off by a regeneration. Ride along with the vehicle and it turns into a monitored drive out of Higher Porthpean. Park it and the regeneration is done on the spot, with running data read once it is done. Then a second scan, verifying the change, putting out the warning light and listing anything still showing. Both sets of figures are sent over, so the before and after figures are recorded. ## The problems a DPF clean cannot cure Only one fault is answered by a clean: the filter choked with ash and soot. It does nothing for: - sensors, pressure, flagging a restriction that is not real - the EGR valve jammed open - the AdBlue system going wrong - a regeneration that hardly ever runs, because of glow plugs or injectors - a turbo putting oil through the filter The first check is there for exactly that. Transpiring to be one of them means hearing it before the work starts, not after settling up anything. Cutting the filter out is not a remedy: without a functioning DPF a vehicle fails its MOT, and driving it is against the law. DPF renewal is the term people search for, though nothing is exchanged — your own filter is cleared in place and sent back into use. Two more worth noting. ## The price of DPF cleaning around Higher Porthpean A call-out charge holds whatever the outcome, and pays for the visit, the booking fee, the scan and the advice passed on. The clean itself starts from £299. The figure is fixed on the phone, once we know the vehicle and what the filter is going to need. No flat rate could be truthful. What you run and where you are both shift it: Higher Porthpean itself, over at Duporth, or otherwise out within the PL postcode area. If the scan writes cleaning out, there is no charge to pay for it. Because the visit, the diagnostic and the advice have been done, the call-out charge nonetheless applies. If the light reappears inside that window, an engineer heads back out to Higher Porthpean — the job carries a 30-day warranty including aftercare. ## Where we get to around Higher Porthpean, and what we clean One mobile service spans cars and estates, vans of any size and light commercials, HGVs and lorries, plant and construction machinery and farm vehicles, and on every one the filter is treated where it sits rather than carried anywhere. Engineers are along Porthpean Road nearly every week, so Higher Porthpean is rarely a special trip, and the same run covers Duporth, Mount Charles and the places out past Charlestown. Call anyway from further out around Cornwall. Coverage runs UK-wide, and the day you are offered depends on the calendar rather than how far away you are. ## About Higher Porthpean Higher Porthpean is a small coastal hamlet in Cornwall, situated near the town of Charlestown and the villages of Lower Porthpean and Duporth.

It may, provided you get it in time and limp mode has not begun. It wants a long run at motorway speed, not ten minutes flat to Asda and back. The visit takes how long? Expect typically around 2 hours — heavily clogged filters sometimes require a second pass, which lengthens it. How much does it cost in Higher Porthpean? Treatment opens from £299, and the call-out charge on top pays for the visit, the check and the advice. The vehicle and your address both change the figure, so we price on the phone. Must I be there in person? A spot for the vehicle to sit, for a couple of hours, is all that is needed. Not you. The regeneration can be run as a monitored drive if you would prefer to ride along. When can someone get to Higher Porthpean? It is often same-day or next-day, depending on what is currently in the calendar. Ring 0303 330 1830 what is free across the PL area.
