A technician turns up at your door across Dulas, treats the diesel particulate filter while it is attached to the car, runs a DPF regeneration, and you hold on to the filter you came with. Nobody leaves until the figure is fixed on the phone. The visit takes typically around 2 hours and the clean begins from £299. Most owners find us with the light showing, and the motor down on power. That is the position this page is meant for. ## What to try when the DPF light is on Not the unit, automatically. First thing to say. That light can arise from several faults, not just one, so the visit begins with a scan and not with treatment. The motoring you get in the meantime matters. That is the other thing. - Amber light, vehicle even now driving as normal — a long constant run can yet sort it by itself. Costs nothing at all, and worth trying before you ring anything. - Car already fallen into limp mode — that window has shut. A drive will not touch it now. - Stop planning long drives and get it looked at if the car smells of diesel or there is black smoke when you pull away. ## Before the light, what the vehicle was telling you By the time the light appears, things have normally been deteriorating for weeks. It is belated news: - going uphill, the power falls off - you notice the revs fall short of where they used to go - fuel economy turning worse - the stop/start silently bowing out - diesel in the interior, or smoke on the way up through the gears That is not evidence alone. With the light with them, the filter is a fair bet. ## Choked diesel particulate filters around Dulas, and the cause For a DPF, the worst driving is the type you get around a rural hamlet such as Dulas. The school run to Ewyas Harold Primary School, Wern Ddu at a crawl at the morning rush, a few minutes to the local shops, the hop to Abergavenny — nothing of it runs long enough or gets hot enough for the filter to complete a regeneration. The soot builds up rather than clearing. The M50 stands under 25 miles from Dulas, Hereford under 15 miles off, and unless something takes you out that way regularly, full weeks slip past without the long unbroken run that empties a DPF. Geography does not assist. ## The point a DPF regeneration can no longer complete The motor is protecting itself, which is what limp mode means. With power capped and the revs held, the regeneration the filter wants can never complete at all. That tells, because starting one is exactly what a long run does. The usual advice — run it up the motorway — is good, until it is not. The far side of that point — limp mode — road work will not manage it, and the filter wants cleaning. ## DPF cleaning at the vehicle across Dulas Most people do not anticipate this bit: the filter remains. The job takes place with the DPF yet bolted to the car — on your drive, in a work car park, any place the vehicle can stand for a while. Nothing is cleaned until other faults are cleared. That involves a diagnostic first: live data off the ECU, soot load by proportion and by mass, and a review of the sensor readings, glow plugs and related hardware. Then comes the clean itself: a cleaning solution in through the motor's own access point, opening out inside the filter and lifting what a regeneration never can. A second pass is sometimes called for on badly blocked filters. Then a regeneration, to clear what the clean has freed. Either it goes as a monitored drive out of Dulas, with you there, or it goes where the vehicle sits and the running data is read after. Both sets of figures go over by email, so the figures from either end are kept. The second diagnostic is what confirms the change, clears the light and notes whatever is still showing. ## When a DPF clean is not the fix One thing is what cleaning fixes — a filter blocked with soot and ash. It does little for: - pressure or temperature sensors reporting a blockage that is not there - a stuck-open EGR valve - an AdBlue system problem - injectors or glow plugs that prevent a regeneration starting whatsoever - a turbo passing oil through the filter The first scan is there for exactly that. Where it proves to be one of those, you are let know before any work begins rather than after you have settled up anything. Hollowing the filter out is not a solution: without a serviceable DPF a vehicle cannot pass its MOT, and driving it is against the law. DPF renewal is the phrase people type in, though nothing is replaced — your original filter is cleared in place and sent back into use. Two more worth bearing in mind. ## DPF cleaning costs in Dulas Any visit carries a call-out charge — travelling to you, making the booking, running the diagnostic and passing on the advice. The clean itself begins from £299. Once we are told what you drive, and broadly what the filter will take, the figure gets fixed by phone. A single price for all would not be honest. The place you are tells as much as what you own: Dulas itself, Abbey Dore close by, or otherwise out within the HR postcode area. A clean that will not do it is not a clean you pay for, and the check is what says so. You nonetheless pay that charge: someone came out, carried out the diagnostic and passed on you the advice. If the light returns inside that period, an engineer comes back out to Dulas — the work includes a 30-day warranty including aftercare. ## What we clean, and how far we travel around Dulas The filter is cleaned on the vehicle on all of them: private cars, vans of any size and light commercials, HGVs and lorries, plant machinery, agricultural machinery. Nothing is taken anywhere. Engineers are along Wern Ddu nearly every week, so Dulas is hardly ever a special trip, and the same run takes in Abbey Dore, Ewyas Harold and the places out past Pontrilas. It is the schedule, not the distance, that decides whether it is one day or the next, and coverage extends UK-wide — so call still from even further out through Herefordshire. ## About Dulas Dulas is a small hamlet situated on the banks of a river in Herefordshire, with a low elevation of around 99 metres. Dulas lies approximately 10 miles from the city of Hereford and is surrounded by other rural communities such as Abbey Dore and Ewyas Harold. Dulas has a population of around 296 people and is characterised by detached housing. Dulas is located in a relatively remote area, with London being around 123 miles away. ## What Dulas drivers want to know about DPF cleaning Will a long drive clear it? Sometimes, if you spot it early and the car has not fallen into limp mode. That calls for motorway speed for a long spell, rather than a quick trip to the local shops. How long does the visit last? It is typically around 2 hours. A badly clogged filter can require a second clean, which adds to that. In Dulas, what does it come to? It opens from £299, plus the call-out charge taking in the visit, the check and the advice. Both the vehicle and where you are move it, which is why pricing happens by phone. Have I need to be there? No. The vehicle needs space to wait for a couple of hours; nobody expects you to stand with it. Ride along if you prefer, and the regeneration turns into a supervised drive. When can someone come to Dulas? That comes down to the schedule, but it is often same-day or next-day. Phone 0303 330 1830 and you will learn what is available across the HR area. The filter — does it come away from the vehicle? It is done where it sits, on the call-out service. Taking a filter off or bolting one back on count as anything a job we do either way. The light returns — then what? Taken in by the 30-day warranty: aftercare, and an engineer travelling back to Dulas. ## Put a DPF clean booked in Dulas Tell us round what the motor is doing on 0303 330 1830, whether that is smoke, limp mode or the light.
