No workshop, no filter leaving. A technician travels to your door across Week, treats the diesel particulate filter in place, carries out a DPF regeneration, and you end up with the filter you arrived with. Reckon on the visit lasting typically around 2 hours. The clean begins from £299, fixed by the phone before anyone travels. The light is showing and the motor is low on power — that is how we usually find people, and what this page deals with. ## Your DPF light is lit — what now? The DPF is not necessarily what is to blame, and that comes first. A diagnostic goes before any work, because that same dash light has plenty of possible faults behind it. The use you do in the meantime matters. That is the other thing. - Amber light, car still driving normally — a long constant run can yet sort it alone. Costs nothing at all, and worth a try before you ring anything. - A drive will not shift it now — limp mode means that window has now closed. - A diesel smell in there, or black smoke under acceleration, is the stage to stop arranging long drives and ring. ## Before the light, what the vehicle was telling you Last news, the light. The symptoms generally mount for weeks before it shows: - tailing off on power, especially uphill - revs that will not climb the way they once did - the fuel consumption is worse - stop/start without a word packing in - smoke under the throttle, or a diesel smell inside That is not conclusive alone. With the light, it is a fair guess the filter is blocked. ## Why diesel particulate filters block around Week Week is a rural hamlet, and the motoring that belongs to one is the least kind kind for a DPF. Nothing of it goes on long enough or is hot enough for the filter to see through a regeneration: the school run to North Tawton Community Primary School and Nursery, Fore Street barely moving at half eight, five minutes to Costcutter, the run to Okehampton. What should burn off stays behind. The M5 stands under 25 miles from Week, Exeter under 25 miles off, and unless something carries you out that way often, full weeks go by without the long unbroken run that empties a filter. Geography does not help. ## DPF regeneration, and the moment limp mode ends it The vehicle is protecting itself, which is what limp mode is. With pulling power held down and the revs held, the regeneration the filter needs can never run at all. That counts, because triggering one is just what a long run does. The common advice — take it up the motorway — is sound, right until it is not. The filter requires cleaning rather than road work once the car has gone into limp mode. ## DPF cleaning at the motor across Week On your front, in a work car park, wherever the car can sit for a couple of hours: the job is done with the filter yet fitted on, which is the detail most drivers do not anticipate. The ECU is interrogated first, reporting soot load by percentage and by weight, along with a review of sensor feeds, glow plugs and connected components, so nothing is cleaned while another fault is still open. Next comes the clean itself: cleaning fluid in through the car's own access port, opening out inside the filter and lifting what a regeneration cannot. Where the filter is badly blocked, plan on a second pass. Next, a regeneration clears everything the clean lifted. If you are there, that is done as a monitored drive out of Week; if not, on the spot where the motor sits, with the real-time data checked afterwards. Then a second check, verifying the change, putting out the warning light and logging anything still outstanding. Both sets of figures are emailed over, so the before and after figures are kept. ## When a DPF clean is not the fix A clean cures one thing: a filter choked with soot and ash. It does no good for: - pressure or temperature sensors flagging a blockage that is not there - an EGR valve stuck open - the AdBlue system playing up - glow plugs or injectors preventing the regeneration starting in the first place - a turbo passing oil through the filter Finding that out is the first scan's whole job. You are let know before any work starts, not after you have paid, if it turns out to be one of those. Hollowing the filter out is not a solution: without a serviceable DPF a vehicle cannot pass its MOT, and driving it is an offence. DPF renewal is the term people look up, though nothing is replaced — your existing filter is cleared in place and sent back into use. Two more worth noting. ## Prices for DPF cleaning in Week A clean 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. Once we know what you run, and about what the filter will need, the number gets fixed over phone. A single price for everyone would not be truthful. Whereabouts you are matters as much as what you own: Week itself, Ashridge Court next door, or further out across the EX postcode area. If the diagnostic rules a clean out, there is nothing to pay for it. You still pay that charge: someone turned up, carried out the scan and gave you the advice. The clean includes a 30-day warranty covering aftercare, including an engineer coming back out to Week if the light reappears inside that time. ## The vehicles we clean and the ground we cover around Week Cars, vans and light commercials, HGVs, construction and plant machinery, farm vehicles — one on-site service across all of them, and on all of them the filter is done where it sits rather than taken anywhere. The same round that has engineers on Fore Street most weeks picks up Week, Ashridge Court, Trecott and the places beyond North Tawton. It is the calendar, not the distance, that decides whether it is one day or the next, and coverage runs UK-wide — so phone even from farther out through Devon. ## Week itself Week is a small hamlet in Devon, situated on the riverside in the South West of England. Week sits at an elevation of 119 metres, near the city of Exeter and close to nearby places such as North Tawton and Ashridge Court. Week has a population of around 390 people, predominantly living in terraced housing. ## Common questions on DPF cleaning across Week Does a long run sort it? It might, provided you get it early and limp mode has not begun. Five minutes to Costcutter and back will not do it; motorway speed, kept for some time, will. About how long does it take? That is typically around 2 hours, though a severely loaded filter can require cleaning twice, which takes longer. Around Week, what does it come to? A clean starts from £299, and the call-out charge on top pays for the visit, the check and the advice. The vehicle and your address both move the number, so we settle it on the phone. Is it necessary for me to be there? The vehicle wants a spot for two hours or so. You need not be in it. Wanting to be there is welcome: the regeneration then is done out on the road, monitored. How soon can someone get to Week? It is often same-day or next-day, depending on what is already in the schedule. Phone 0303 330 1830 and we will let you what is available across the EX area. Will the filter be taken off? On the on-site service, no: the filter is done in place. Neither job — a filter off, a filter back on — is not work we do. What if the light comes back? Taken in by the 30-day warranty: aftercare, and an engineer travelling back to Week. ## Have a DPF clean booked across Week Walk us round what the vehicle is doing on 0303 330 1830, whether that is smoke, limp mode or the light.
