An engineer turns up at your place across Alwington, treats the diesel particulate filter while it is fitted to the motor, carries out a DPF regeneration, and you end up with the filter you arrived with. You'll be given a figure by phone before anyone goes, the clean opening from £299, and the visit running typically around 2 hours. Most people find us with the light already on, and the vehicle low on power. That is the situation this page is meant for. ## What to do when the DPF light is on First thing: it is not always the unit. That light can arise from several faults, not just one, so the visit begins with a scan and not with a clean. It counts what you get with the car between now and the appointment. - Worth a go before you book anything: amber light, motor driving fine, just one constant run, no cost. - A drive will not shift it now — limp mode means that window has now closed. - A diesel smell in the car, or black smoke under hard acceleration, is the point to stop arranging long drives and book it in. ## Before the light, what the motor was warning you Last news, the light. The symptoms generally grow for some time before it arrives: - tailing off on power, above all uphill - an engine whose revs will not pull as before - worse fuel consumption - stop/start silently giving up - the interior smelling of diesel, or smoke when you pull away Any one of those, taken by itself, is not conclusive. With the light with them, the filter is a fair guess. ## Why diesel particulate filters clog round Alwington For a DPF, the worst motoring is the sort you find across a rural hamlet such as Alwington. Nothing of it runs long enough or gets hot enough for the filter to complete a regeneration: the school run to Parkham Primary School, Dotheridge Lane standing at the morning rush, five minutes to Buckland Brewer Community Shop, the dash to Barnstaple. The unburnt soot collects rather than clearing. The M5 lies under 50 miles from Alwington, Exeter under 50 miles away, and unless something takes you out that way routinely, whole weeks slip past without the long steady run that scours a DPF. Geography does not help. ## Why limp mode stops a DPF regeneration The motor is defending itself, which is what limp mode means. Output is limited, the revs will not rise, and the regeneration the filter requires can not happen — which is the real difficulty, because a proper drive works by triggering that regeneration. Sound advice, that motorway run — up until the moment it is not. Once the motor is in limp mode you are beyond that line, and the filter wants cleaning rather than driving. ## Where the car stands is where the DPF is treated round Alwington On your front, in a work car park, any place the car can stand for a while: the job takes place with the filter even now bolted on, which is the bit most owners do not see coming. First a scan. Real-time ECU data, the soot load as a proportion and as a mass, the sensor readings, the glow plugs, the related components — all of it taken before anything is started. A cleaning solution then goes in through the access port on that motor, opening out inside the filter to loosen soot and ash a regeneration on its own will never budge. Where the filter is heavily blocked, plan on a second pass. What the clean has lifted is then burned off by a regeneration. Either it runs as a monitored drive out of Alwington, with you along, or it runs where the car sits and the live data is verified afterwards. A second check verifies the change, clears the warning light and logs anything still outstanding. Both read-outs are emailed over, so you keep the before and after figures recorded. ## The problems a DPF clean cannot cure Only one fault is answered by a clean: the filter clogged with ash and soot. It does nothing for: - sensors, pressure or temperature, reporting a blockage that is not real - an EGR valve held open - the AdBlue system failing - worn glow plugs or injectors, so not one regeneration ever starts - turbo failure, with oil getting into the filter The first check is there for precisely that. Where one of those proves the fault, you find out about it up front rather than once the money has changed hands for good. DPF renewal is what people look up, but no part is exchanged: the filter you have is treated where it sits and returned to use. Nor is having it cut out a fix, since the MOT then fails and driving becomes unlawful. Two more things worth knowing. ## DPF cleaning prices across Alwington A call-out charge holds whatever the outcome, and takes in the visit, the booking fee, the scan and the advice offered. Cleaning itself opens from £299. The price is fixed over the phone, once we are told the vehicle and what the filter is likely to need. No flat rate could be straight. What you own and where you are both shift it: Alwington itself, out at Woodtown, or further out within the EX postcode area. If the check writes cleaning out, there is not a penny to pay for it. Because the visit, the scan and the advice have happened, the call-out charge even so holds. If the light comes back inside that period, an engineer travels back out to Alwington — the work carries a 30-day warranty including aftercare. ## What we clean, and how far we go near Alwington The filter is cleaned where it sits on all of them: private cars, panel vans and light commercials, HGVs, plant machinery, agricultural machinery. Nothing is moved anywhere. Alwington is hardly ever a special trip: technicians are out on Dotheridge Lane most weeks, and the same run covers Woodtown, Ford and the villages out past Fairy Cross. Even further out around Devon is even so worth phoning about — coverage runs UK-wide, and it is the diary rather than the distance that settles between one day and the next. ## A line on Alwington Alwington is a small hamlet in Devon, situated near the coast and approximately 122 metres above sea level. Alwington lies within a short distance of several nearby settlements, including Woodtown, Fairy Cross, and Goldworthy. Alwington is characterised by its predominantly detached housing stock, reflecting its rural setting. Alwington is located around 37 miles from Exeter, the nearest city. ## Questions Alwington drivers ask about DPF cleaning Can I simply take it for a long drive? Soon enough, and with the car out of limp mode, yes — sometimes. That calls for motorway speed for a long stretch, rather than a brief trip to Buckland Brewer Community Shop. How long does the visit last? Bank on typically around 2 hours, with a second clean adding to that where the filter is badly blocked. In Alwington, what does it run to? The call-out charge takes in the visit, the diagnostic and the advice; treatment itself starts from £299. Both the vehicle and where you are shift it, which is why pricing happens by phone. Must I be there in person? No. The vehicle wants somewhere to wait for a couple of hours; you do not need to stand with it. Wanting to be there is no problem: the regeneration then runs out on the road, monitored. How soon can someone come to Alwington? That hangs on the schedule, but it is often same-day or next-day. One phone call to 0303 330 1830 and you will hear what the EX area has available. Will the filter be taken off? Not on the mobile service — it is done where it sits. Neither taking a filter off nor bolting one back on is work we do. The light returns — then what? Aftercare comes inside the 30-day warranty, and that includes an engineer returning to Alwington. ## Have a DPF clean booked around Alwington Talk us about what the motor is doing on 0303 330 1830, whether that is smoke, limp mode or the light.
