Your car will not be taken anywhere and the filter does not budge. An engineer arrives at your place across Marsh, treats the diesel particulate filter fitted to the motor and runs a DPF regeneration. The visit takes typically around 2 hours, the clean starts from £299, and the price is settled by the phone before anyone leaves. If the light is on already and the vehicle is down on power, this page is for you. That is how most people end up here. ## What to try when the DPF light comes on It could not be the unit at all. That is the main thing. Several faults put the very same light on the very same dash, which is why a visit starts with a diagnostic rather than with a clean. Second thing: how you drive it between now and then matters. - Amber light, car yet driving normally — a long constant run can yet sort it alone. Costs nothing at all, and worth a try before you ring anything. - That window has closed once the car has slipped into limp mode. Motoring will not do it now. - Diesel smell in the cabin, or black smoke under acceleration — stop booking long drives and get it seen to. ## What the vehicle has been telling you Symptoms have generally been building for some time before the light even appears. Late news, in other words: - less power, particularly pulling uphill - revs that will not rise the way they always did - the fuel use is worse - the stop/start quietly bowing out - diesel in the car, or smoke on the way up through the box That is not conclusive on its own. With the light, it is a fair guess the filter is full. ## Choked diesel particulate filters near Marsh, and the reason For a DPF, the worst use is the sort you get in a rural hamlet such as Marsh. The school run to Buckland St Mary Church of England Primary School, A303 at a halt at half eight, five minutes to Sainsbury's, the run to Axminster — nothing of it runs long enough or gets hot enough for the filter to finish a regeneration. What should clear stays behind. The M5 lies under 10 miles from Marsh, Exeter under 25 miles out, and unless something takes you out that way regularly, full weeks slip past without the sustained run that scours a DPF. Geography does not oblige. ## Limp mode, and when DPF regeneration stops It is self-protection: that is all limp mode is. Output is capped, the revs will not climb, and the regeneration the filter needs can not complete — which is the entire catch, because a long drive works by starting that regeneration. Running it up the motorway is the common advice, and it holds up to a point. Once the vehicle is in limp mode you are past that line, and the filter wants treatment rather than driving. ## Call-out DPF cleaning where the car stands in Marsh On your front, in a work car park, wherever the motor can sit for a couple of hours: the job takes place with the filter still fitted on, which is the bit most owners do not anticipate. The ECU is read first, showing soot load by percentage and by weight, along with a look over of sensors, glow plugs and related hardware, so nothing is touched while another fault is still open. Soot and ash that a regeneration by itself will never budge are lifted second, by a solution put through the access port on that car, which spreads inside the filter. Badly clogged filters sometimes need a second pass. Next, a regeneration burns off everything the clean loosened. If you are there, that is run as a monitored drive out of Marsh; if not, on the spot where the vehicle stands, with the live data read after. A second diagnostic confirms the change, clears the warning light and lists anything still open. Both read-outs are emailed over, so you have the before and after figures to hand. ## Where cleaning is not the fix A filter clogged with soot and ash is the one thing cleaning cures. It will not help: - a temperature or pressure sensor reporting a blockage that is not there - the EGR valve stuck open - an AdBlue system problem - a regeneration that hardly ever completes, because of glow plugs or injectors - oil passing through the filter from a faulty turbo Which is why the scan happens first. If it turns out to be one of those, you are warned before any work starts rather than after you have handed over for it. Cutting the filter out is not a fix: without a functioning DPF a vehicle will fail its MOT, and driving it is illegal. DPF renewal is the term people type in, though nothing is replaced — your existing filter is treated in place and sent back into use. Two more worth knowing. ## What DPF cleaning comes to around Marsh The clean starts from £299. A call-out charge covers every visit, and takes in the call-out itself, the booking, the scan and the advice that follows. Quoting a flat rate would not be truthful. We fix it by phone, once the vehicle and its likely needs are known. What you own and where you are both shift it: Marsh itself, out at Bishopswood, or farther out in the EX postcode area. Where the diagnostic says cleaning will not help, you are not billed for cleaning. Because the visit, the diagnostic and the advice have happened, the call-out charge nonetheless stands. A 30-day warranty covers aftercare on the work, and that includes an engineer travelling back out to Marsh if the light reappears inside the window. ## Vehicles we clean, and where we travel near Marsh A single on-site service spans cars and estates, vans and light commercials, HGVs, construction and plant machinery and farm vehicles, and on every one the filter is done where it sits rather than carried anywhere. Week in week out there is already someone on A303, so Marsh rarely means a special trip, and Bishopswood, Higher Beetham and the villages past Yarcombe are on the way. Ring anyway from even further out through Devon. Coverage reaches UK-wide, and the date you are offered comes down to the diary rather than how far away you are. ## About Marsh Marsh is a small hamlet in Devon, situated on the riverside in the South West of England. Marsh sits at an elevation of 148 metres, surrounded by rolling countryside and nearby places such as Howley and Bishopswood. Marsh is characterized by its predominantly detached housing stock, reflecting its rural setting. Marsh is located approximately 23.7 miles from Exeter, the nearest city. ## Questions Marsh drivers ask about DPF cleaning Is a long drive enough on its own? If you get it early enough, and the motor is not in limp mode, sometimes. It wants a sustained run at motorway speed, not five minutes flat to Sainsbury's and back. How long does the visit take? That is typically around 2 hours, though a badly blocked filter can need cleaning twice, which runs on. What does it come to around Marsh? Opening from £299, with a charge for coming out that pays for the diagnostic and advice on what to do next. Both the vehicle and where you are move it, which is why quoting is done by phone. Must I be around in person? Somewhere for the car to wait, for a couple of hours, is all that is wanted. Not you. The regeneration can be carried out as a watched drive if you would prefer to come along. Getting to Marsh — how soon? Depending on the schedule, often same-day or next-day is normal. Ring 0303 330 1830 and you will learn what is free across the EX area. Will the filter be removed? It is treated where it sits, on the mobile service. That job — a filter off, a filter back on — is not something we do. Suppose the light reappears? The 30-day warranty includes aftercare, including an engineer heading back to Marsh. ## Book a DPF clean across Marsh Ring 0303 330 1830 and tell us what the car is doing — light, limp mode, smoke, whatever it is.
