No body shop, no filter leaving. A fitter drives out to your door over in Freystrop, cleans the diesel particulate filter where it is, carries out a DPF regeneration, and you end up with the filter you came with. Nobody sets off until the number is fixed on the phone. The visit lasts typically around 2 hours and the clean begins from £299. Most drivers find us with the light on already, and the vehicle down on power. That is the position this page is meant for. ## What to try when the DPF light comes on It could not be the DPF in the end. That is the main thing. That light can follow plenty of faults, not merely one, so the visit opens with a diagnostic and not with treatment. Second thing: how you handle it between now and then makes a difference. - A long constant run may still do it, provided the light is amber and the vehicle goes normally. Costs zero, so attempt that before calling. - That window has gone once the car has slipped into limp mode. Driving will not do it now. - Stop arranging long drives and get it seen to if the interior stinks of diesel or there is black smoke when you accelerate. ## Signs the vehicle has been showing you Last news, the light. The symptoms usually mount for weeks before it arrives: - power dropping away, particularly climbing uphill - revs that will not climb the way they used to - worse fuel consumption - without a word, the stop/start gives up - smoke under acceleration, or a diesel smell inside On its own, none of that is proof. Next to the light with them, the filter is a fair assumption. ## What blocks diesel particulate filters around Freystrop For a DPF, the poorest driving is the sort you meet across a coastal village such as Freystrop. Run through an ordinary week: the local primary school and home, Poplar Meadow at a standstill before half nine, a short hop to Nisa Local, a hop to Johnston. Nothing there lasts long enough or gets hot enough to see through a regeneration. Instead of burning off, the soot collects. Neither is a long way from Freystrop: under 50 miles to the M4, under 25 miles to St Davids. Neither is on the way to anywhere most weeks, though, so the drive that would empty a filter simply never happens. ## Why limp mode prevents a DPF regeneration Limp mode is the motor protecting itself. Output is limited, the revs will not climb, and the regeneration the filter needs can never happen — which is the entire problem, because a proper drive works by setting off that regeneration. The standard advice — take it up the motorway — is good, until it is not. Once the car is in limp mode you are the far side of that point, and the filter needs a clean rather than more driving. ## DPF cleaning at the motor in Freystrop On your front, in a work car park, anywhere the car can sit for a while: the job is done with the filter yet bolted on, which is the bit most owners do not anticipate. A check goes first — real-time data off the ECU, soot load by proportion and by weight, and a check of the sensor readings, glow plugs and associated components, so other faults are cleared before any of it is touched. Soot and ash that a regeneration alone will never shift are loosened next, by a cleaning solution passed through the access point on that car, which opens out inside the filter. Sometimes a filter is loaded enough to need doing twice. A regeneration comes next, clearing what the clean has lifted. If you are there, that is run as a monitored drive out of Freystrop; if not, statically where the car waits, with the live data read after. Finally the diagnostic runs again — the change confirmed, the light cleared, anything still showing written down. Both reports come to you by email, so the numbers are recorded. ## Where a clean is not the fix Only one fault is answered by treatment: the filter choked with ash and soot. It does nothing for: - a pressure or temperature sensor showing a restriction that is not there - the EGR valve jammed open - an AdBlue system failure - glow plugs or injectors preventing the regeneration completing in the first place - the turbo pushing oil into the filter Finding that out is the first check's job. When one of those proves the fault, you learn of it in advance rather than once the money has gone for good. DPF renewal is what people look up, but no part is replaced: the filter you own is cleaned where it sits and put back to work. Nor is having it gutted a solution, since the MOT then fails and driving becomes an offence. Two more things worth bearing in mind. ## DPF cleaning costs across Freystrop The treatment starts from £299. A call-out charge covers every visit, and takes in the call-out itself, the booking, the check and the advice that comes with it. Publishing a flat rate would not be honest. We fix it over phone, once the motor and its probable needs are known. The car shifts it, and so does the address — Freystrop, Clareston, or a spot farther out in the SA postcode area. You are not asked to pay for treatment that the diagnostic says will not help. You nonetheless pay that charge: someone travelled, ran the check and offered you the advice. A 30-day warranty takes in aftercare on the work, and that includes an engineer travelling back out to Freystrop if the light returns inside the time. ## The vehicles we clean and the area we cover round Freystrop One mobile service spans cars and estates, panel vans and light commercials, heavy goods vehicles, plant machinery and agricultural machinery, and on every one the filter is cleaned on the vehicle rather than taken anywhere. Most weeks there is usually someone on Poplar Meadow, so Freystrop rarely means a special trip, and Clareston, Little Milford and the spots past Hook are on the way. It is the calendar, not the distance, that picks whether it is one day or the next, and coverage runs UK-wide — so ring still from even further out through Pembrokeshire. ## A line on Freystrop Freystrop is a small village in Pembrokeshire, situated near the coast of Wales, with an elevation of around 70 metres.

Early enough, and with the vehicle out of limp mode, yes — sometimes. It takes a sustained run at motorway speed, not five minutes or so to Nisa Local and back. Roughly how long does it last? Expect typically around 2 hours — heavily clogged filters sometimes take a second pass, which adds to it. The cost in Freystrop — what is it? Cleaning starts from £299, and the call-out charge on top takes in the visit, the diagnostic and the advice. The vehicle and your address both move the figure, so we settle it on the phone. Is it necessary for me to be present? You need not stand with it — the vehicle just wants somewhere to stand for a couple of hours. The regeneration can be done as a supervised drive if you would sooner be there. When can someone come to Freystrop? It is often same-day or next-day, depending on what is currently in the diary. Ask 0303 330 1830 what is open across the SA area. The filter — does it leave the motor? Treated where it is, on this service, so no. Neither job — a filter off, a filter back on — is not a job we do. What if the light returns? The 30-day warranty includes aftercare, including an engineer heading back to Freystrop. ## Book a DPF clean in Freystrop Walk us through what the vehicle is doing on 0303 330 1830, whether that is smoke, limp mode or the light.
