A fitter turns up at your address across Willett, clears the diesel particulate filter while it is attached to the vehicle, performs a DPF regeneration, and you hold on to the filter you arrived with. The visit runs typically around 2 hours, the clean opens from £299, and the number is fixed by the phone before anyone travels. The light is showing and the vehicle is down on power — that is how we normally meet people, and precisely what this page deals with. ## Your DPF light is on — what then? It may not be the unit in the end. That is the main thing. Several faults put the same light on the very same dashboard, which is why a visit starts with a diagnostic rather than with a clean. Second thing: how you run it between now and then matters. - Vehicle yet driving as normal on an amber light — have a go at a long even run first. It costs zero and regularly sorts the filter without help. - A drive will not shift it now — limp mode means that window has by then closed. - Stop arranging long drives and get it looked at if the cabin stinks of diesel or there is black smoke when you pull away. ## Before the light, what the motor was showing you By the time the light arrives, things have generally been going wrong for a while. It is belated news: - less power, particularly pulling uphill - you notice the revs stop short of where they always went - worse fuel use - quietly, the stop/start packs in - diesel in the interior, or smoke on the way up through the box By itself, none of that is proof. The light with them suggests a loaded filter. ## What blocks diesel particulate filters round Willett Being a rural hamlet, Willett throws up precisely the use a DPF manages worst. Look at a typical week: Lydeard St Lawrence Community Primary School and home again, Dean's Lane at a standstill before nine, a five-minute run to Co-op Food, a dash to Taunton. Nothing there lasts long enough or runs hot enough to finish a regeneration. Instead of burning away, the soot load collects. Neither is far from Willett: under 10 miles to the M5, under 50 miles to Cardiff. Neither is on the way to much most weeks, though, so the drive that would scour a filter never comes. ## The point a DPF regeneration can no longer run It is self-protection: that is all limp mode is. Output is capped, the revs will not pull, and the regeneration the filter wants can not happen — which is the entire problem, because a proper drive works by setting off that regeneration. Taking it up the motorway is the common advice, and it holds right up to a limit. In limp mode you are the far side of that point: treatment is what will do it, not more miles. ## Mobile DPF cleaning where the car stands in Willett On your front, in a work car park, any place the motor can stand for a couple of hours: the job happens with the filter yet bolted on, which is the detail most drivers do not see coming. First a diagnostic. Live ECU data, the soot load as a proportion and as a mass, the sensors, the glow plugs, the associated hardware — all of it taken before a thing is touched. A solution then is injected through the access port on that motor, opening out inside the filter to loosen soot and ash a regeneration by itself will never budge. Where the filter is heavily loaded, expect a second pass. Next, a regeneration clears everything the clean freed. Either it goes as a monitored drive out of Willett, with you there, or it is done where the vehicle stands and the real-time data is verified after. Both sets of figures come through by email, so the figures from either end are recorded. The second check is what confirms the change, resets the light and lists whatever is still showing. ## Where treatment is not the fix One thing is what treatment fixes — a filter choked with soot and ash. It does little for: - a temperature or pressure sensor flagging a block that is not there - EGR valves that stick open - AdBlue system faults - failed glow plugs or injectors, so never a regeneration ever starts - turbo problems, with oil reaching the filter The first diagnostic is there for just that. Turning out to be one of them means hearing it before the work gets going, not after settling up for it. 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 cut out a solution, since the MOT then fails and driving becomes illegal. Two more things worth knowing. ## DPF cleaning prices around Willett Cleaning opens from £299, with the call-out charge on top of that for every visit — it pays for the call-out, the booking, the checks and the advice. Not one flat rate would be honest, so the number is agreed on the phone once we are told the vehicle and what the filter is going to need. What you run and where you are both shift it: Willett itself, over at Coleford Water, or otherwise out across the TA postcode area. Where the diagnostic says treatment will not do it, you are not asked to pay for cleaning. You still pay that charge: someone turned up, did the scan and gave you the advice. A 30-day warranty takes in aftercare on the work, and that includes an engineer heading back out to Willett if the light comes back inside the time. ## Vehicles we clean, and where we reach near Willett Cars, vans of any size and light commercials, heavy goods vehicles, plant machinery, agricultural vehicles — a single call-out service across all of them, and on all of them the filter is cleaned where it sits rather than carried anywhere. The same trip that keeps technicians on Dean's Lane most weeks covers Willett, Coleford Water, Rooks Nest and the spots beyond Stogumber. Ring anyway from even further out across Somerset. Coverage extends UK-wide, and the slot you are given depends on the diary rather than how far away you are. ## Willett itself Willett is a small hamlet in inland Somerset, situated at an elevation of 146 metres, with detached housing being the predominant type of accommodation. Willett lies near several local landmarks, including Coleford Water and Rooks Nest, and is close to the nearby settlement of East Town. Willett is located approximately 139 miles west of London and 27 miles east of Cardiff, placing it in a rural area of the South West region. Willett has a small population of around 288 residents. ## Questions Willett drivers ask about DPF cleaning Is a long drive enough by itself? Sometimes, if you spot it early enough and the motor has not dropped into limp mode. A steady run at motorway speed is what it takes — not ten minutes flat to Co-op Food and back. Broadly how long does it run? It is typically around 2 hours. A severely clogged filter can require a second clean, which extends that. In Willett, what does it run to? Treatment begins from £299, and the call-out charge on top covers the visit, the check and the advice. Both the vehicle and where you are change it, which is why pricing goes by phone. Have I got to be present? The vehicle wants a place for two hours or so. Nobody expects you to be in it. The regeneration can be done as a supervised drive if you would sooner come along. Can someone travel to Willett soon? That depends on the diary, but it is often same-day or next-day. One phone call to 0303 330 1830 and you will learn what the TA area has free. Is the filter taken off the vehicle? Not on the mobile service — it is treated where it sits. Neither job — a filter off, a filter back on — is not a job we do. Suppose the light reappears? Aftercare sits inside the 30-day warranty, and that includes an engineer heading back to Willett. ## Arrange DPF cleaning around Willett However it is doing — light, limp mode, smoke — say so when you phone 0303 330 1830.
