Your car is not taken off and the filter does not budge. A technician turns up at your address across Middle Coombe, cleans the diesel particulate filter fitted to the car and carries out a DPF regeneration. You'll know a figure by phone before anyone leaves, the clean starting from £299, and the visit running typically around 2 hours. Written for the state most owners are in: the light on already, the motor struggling for power, and the job still to arrange. ## Your DPF light is showing — what then? The unit is not automatically what is to blame, and that goes first. A check comes before all cleaning, because that same panel light has a number of likely faults behind it. Second thing: how you run it between now and then makes a difference. - A long steady run may even now manage it, provided the light is amber and the car runs fine. Costs zero, so have a go at that before ringing. - Once the vehicle is in limp mode, a long run will not shift it. The window has shut. - Stop arranging long drives and get it checked if the car stinks of diesel or there is black smoke when you accelerate. ## The motor has been showing you already By the time the light shows, things have usually been deteriorating for some time. It is belated news: - going uphill, the power falls off - you notice the revs fall short of where they used to go - worse fuel use - the stop/start quietly bowing out - diesel in the cabin, or smoke on the way up through the gears Alone, none of that is proof. Next to the light, it is a fair assumption the filter is full. ## Blocked diesel particulate filters near Middle Coombe, and the reason Being a rural hamlet, Middle Coombe generates just the use a DPF handles the poorest. A regeneration wants the time and heat, and sees not much: not on the school run to Ludwell Primary School, not on Salisbury Road at the morning rush, not on a few minutes to Lidl, and not on the run to Tisbury. Instead of clearing, the soot load collects. Save when you have a standing cause to get out to the M27, under 50 miles from Middle Coombe, or out to Salisbury under 25 miles away, whole weeks go by without a long unbroken stint. Geography is against you. ## Why limp mode stops a DPF regeneration The motor is defending itself, which is what limp mode means. Pulling power is held down, the revs will not rise, and the regeneration the filter requires can not run — which is the entire catch, because a sustained drive works by starting that regeneration. So the usual advice to run it up the motorway is sound advice, until the day it is not. The filter needs cleaning rather than driving once the motor has dropped into limp mode. ## The vehicle stays where it is for call-out DPF cleaning round Middle Coombe On your front, in a work car park, anywhere the car can stand for a while: the job takes place with the filter yet fitted on, which is the detail most owners do not anticipate. First a diagnostic. Live ECU data, the soot load as a percent and as a mass, the sensor readings, the glow plugs, the connected parts — all of it read before any of it is touched. Then the treatment. A solution is fed in through the access port on that car and spreads inside the filter, loosening the soot and ash a regeneration on its own will never shift. A second pass is sometimes called for on severely loaded filters. A regeneration comes next, burning off what the clean has freed. If you are there, that is carried out as a monitored drive out of Middle Coombe; if not, on the spot where the vehicle waits, with the real-time data read once done. Then a second check, confirming the change, resetting the warning light and listing anything still logged. Both read-outs are emailed over, so the before and after figures are recorded. ## The problems a DPF clean cannot answer A filter choked with soot and ash is the one thing a clean answers. It will not touch: - a pressure or temperature sensor showing a blockage that is not there - the EGR valve jammed open - an AdBlue system problem - injectors or glow plugs that block a regeneration completing whatsoever - turbo problems, with oil entering the filter That is what the first diagnostic is for. Where one of those proves the fault, you hear about it in advance rather than once the money has gone altogether. DPF renewal is what people search for, but no part is replaced: the filter you have is cleaned where it sits and sent back into service. Nor is having it gutted a remedy, since the MOT then fails and driving becomes illegal. Two more things worth knowing. ## Figures for DPF cleaning around Middle Coombe Treatment begins from £299, with the call-out charge on top of that for every visit — it covers the call-out, the booking, the scans and the advice. The figure is agreed by the phone, once we are told the vehicle and what the filter is likely to need. No flat rate could be honest. What you run and where you are both move it: Middle Coombe itself, across at Lower Coombe, or otherwise out in the SP postcode area. You are not billed for treatment that the diagnostic says will not do it. You nonetheless pay that charge: someone travelled, ran the scan and gave you the advice. If the light returns inside that time, an engineer comes back out to Middle Coombe — the work carries a 30-day warranty covering aftercare. ## Where we get to near Middle Coombe, and what we clean The filter is cleaned in place on all of them: cars and estates, vans of any size and light commercials, HGVs and lorries, plant and construction machinery, agricultural machinery. Nothing is carried anywhere. Engineers are along Salisbury Road most weeks, so Middle Coombe is rarely a detour, and the same run takes in Lower Coombe, Lillies Green and the spots out past Ludwell. Phone anyway from further out through Wiltshire. Coverage extends UK-wide, and the slot you are given hangs on the schedule rather than how far away you are. ## A note on Middle Coombe Middle Coombe is a small hamlet in Wiltshire, situated inland at an elevation of 156 metres, and is located near the villages of Higher Coombe, Ludwell, and Lower Coombe.

Sometimes, if you spot it in time and the vehicle has not slipped into limp mode. A sustained run at motorway speed is what it needs — not fifteen minutes flat to Lidl and back. The visit lasts how long? Reckon on typically around 2 hours, with a second clean adding to that where the filter is badly blocked. What does it run to across Middle Coombe?

Must I be around in person? A spot for the motor to wait, for a couple of hours, is all that is required. Not you.
