The engineer turns up at your door across Ram Alley and gets to work. The diesel particulate filter is treated fitted to the vehicle, a DPF regeneration runs after it, and you hold on to the filter you started with. Nobody travels until the number is agreed over the phone. The visit lasts typically around 2 hours and the clean opens from £299. The light is showing and the vehicle is down on power — that is how we normally come across people, and roughly what this page deals with. ## DPF light on? What comes next First thing: it is not automatically the filter. A diagnostic happens before the work, because that same dashboard light has several possible faults behind it. The driving you manage in the meantime tells. That is the other thing. - Amber light, car even now driving fine — a long constant run can still shift it alone. Costs nothing at all, and worth a try before you book anything. - That window has gone once the motor has slipped into limp mode. Driving will not help now. - A diesel smell in the car, or black smoke under hard acceleration, is the point to stop arranging long drives and call. ## Before the light, what the vehicle was telling you Last news, the light. The symptoms generally grow for a while before it shows: - less power, especially going uphill - an engine whose revs will not rise as they should - fuel economy going worse - the stop/start silently bowing out - the interior stinking of diesel, or smoke when you pull away That is not evidence by itself. The light beside them indicates a full filter. ## Clogged diesel particulate filters near Ram Alley, and the cause For a DPF, the worst driving is the sort you get around a rural hamlet such as Ram Alley. A regeneration needs time and heat, and gets none: not on the school run to Burbage Primary School, not on Marlborough Road at half past eight, not on a few minutes to Tesco, and not on the run to Bedwyn. The unburnt soot builds up rather than burning away. The M4 stands under 10 miles from Ram Alley, Salisbury under 25 miles out, and unless something pulls you out that way regularly, full weeks pass without the long unbroken run that scours a unit. Geography does not oblige. ## DPF regeneration, and the stage limp mode kills it The vehicle is defending itself, which is what limp mode is. With output held down and the revs kept low, the regeneration the filter needs will not complete at all. That tells, because triggering one is just what a long run does. Getting it up the motorway is the common advice, and it works as far as a point. The filter needs treatment rather than road work once the car has dropped into limp mode. ## The car stays put for call-out DPF cleaning in Ram Alley Nothing is taken from the vehicle. That surprises people. The DPF sits bolted where it is and the work is done around it, on a drive, in a works car park, wherever it can stand for two hours or so. First a diagnostic. Live ECU data, the soot load as a percent and as a figure, the sensor feeds, the glow plugs, the related parts — all of it logged before anything is started. Soot and ash that a regeneration on its own will never move are lifted second, by a solution fed through the access port on that car, which expands inside the filter. Sometimes a filter is blocked enough to take doing twice. Next, a regeneration drives off everything the clean loosened. Either it goes as a monitored drive out of Ram Alley, with you present, or it goes where the motor stands and the live data is read after. Then a second scan, verifying the change, resetting the warning light and logging anything still outstanding. Both sets of figures are emailed over, so the before and after figures are on record. ## The failures a DPF clean cannot fix Cleaning answers one thing: a filter clogged with soot and ash. It does little for: - a temperature or pressure sensor flagging a blockage that is not there - an EGR valve stuck open - AdBlue system problems - glow plugs or injectors preventing the regeneration starting at all - turbo trouble, with oil entering the filter That is what the first scan is for. When one of those turns out to be the fault, you hear about it up front rather than once the money has changed hands altogether. Lastly, two things. A vehicle with the filter gutted will fail its MOT, and driving it is an offence, so that is no fix. What gets typed in as DPF renewal exchanges nothing: your filter is cleaned in place and goes back into service. ## DPF cleaning charges around Ram Alley A call-out charge stands whatever the outcome, and takes in the visit, the booking fee, the scan and the advice offered. Cleaning itself opens from £299. No flat rate would be honest, so the figure is agreed on the phone once we have the vehicle and what the filter is going to need. The car moves it, and so does the location — Ram Alley, Wootton Rivers, or somewhere further out in the SN postcode area. A clean that will not do it is not a clean you pay for, and the check is what says so. Because the visit, the scan and the advice have been done, the call-out charge still holds. If the light returns inside that period, an engineer travels back out to Ram Alley — the work includes a 30-day warranty covering aftercare. ## The vehicles we clean and the area we reach around Ram Alley The filter is done where it sits on all of them: cars and estates, vans of any size and light commercials, HGVs, plant machinery, farm vehicles. Nothing is carried anywhere. Ram Alley is seldom a special trip: engineers are along Marlborough Road most weeks, and the same run takes in Wootton Rivers, Burbage and the villages out past Easton Royal. Ring anyway from farther out through Wiltshire. Coverage extends UK-wide, and the date you are offered hangs on the schedule rather than how far away you are. ## The area around Ram Alley Ram Alley is a small hamlet situated on the riverside in Wiltshire, with a mix of detached homes and a rural landscape. Ram Alley sits at an elevation of 154 metres, near the villages of Stibb Green and Westcourt.

It might, provided you get it early enough and limp mode has not begun. Fifteen minutes to Tesco and back will not manage it; motorway speed, kept for some time, will. Does the visit take long? Count on typically around 2 hours, with a second clean extending that where the filter is severely blocked. What does it cost in Ram Alley? Starting from £299, with a charge for coming out that pays for the scan and advice on what to do next. We quote on the phone, because the vehicle and your address both change the price. Have I got to be present? You need not stand with it — the vehicle simply requires a spot to sit for a couple of hours. Come along if you would rather, and the regeneration turns into a watched drive. When can someone come to Ram Alley? That hangs on the diary, but it is often same-day or next-day. Phone 0303 330 1830 and you will know what is open across the SN area. Does the filter come away from the car? Treated where it sits, on this service, so no. That work — a filter off, a filter back on — is not work we do. The light returns — then what? Included by the 30-day warranty: aftercare, and an engineer heading back to Ram Alley. ## Book a DPF clean around Ram Alley Ring 0303 330 1830 and talk us through what the car is doing: a light, limp mode, smoke, whatever it is.
