An engineer turns up at your address across The Roe, clears the diesel particulate filter while it is fitted to the motor, performs a DPF regeneration, and you keep the filter you came with. The visit runs typically around 2 hours, the clean begins from £299, and the number is fixed by the phone before anyone leaves. If the light is showing and the vehicle is down on power, this page is the right one. That is how most owners get to us. ## DPF light on? What happens next The filter is not necessarily what is wrong, and that comes first. Treatment is not where a visit starts. A check is — plenty of faults register as the same warning. The motoring you do in the meantime tells. That is the second thing. - Vehicle still driving fine on an amber light — try a long steady run first. It costs nothing at all and often clears the filter without help. - A drive will not touch it now — limp mode means that window has already gone. - Get it seen to rather than running it — diesel in the car, or smoke on hard acceleration, has gone past the long-run stage. ## Before the light, what the vehicle was showing you The light is late news. By the time it shows, the symptoms have generally been growing for a while: - climbing uphill, the power falls off - you see the revs never reach where they once went - the fuel economy is worse - without a word, the stop/start gives up - smoke under the throttle, or a diesel smell inside None of that is evidence by itself. With the light, it is a fair bet the filter is blocked. ## Why diesel particulate filters choke around The Roe The driving that goes with a residential suburb like The Roe is the poorest type for a DPF. The school run to the local primary school, Hen Waliau at a halt at half eight, five minutes to Co-op Food, the hop to Rhyl — nothing of it goes on long enough or gets hot enough for the filter to see through a regeneration. What should burn off remains. Unless you have a regular cause to drive out to the Moreton Spur, under 25 miles from The Roe, or out to St Asaph under a mile away, entire weeks pass without a long steady stint. Geography is against you. ## DPF regeneration, and the moment limp mode kills it The vehicle is defending itself, which is what limp mode means. Pulling power is limited, the revs will not rise, and the regeneration the filter requires can not happen — which is the whole difficulty, because a long drive works by triggering that regeneration. Sound advice, that motorway run — up until the day it is not. Once the motor is in limp mode you are past that point, and the filter needs a clean rather than more driving. ## Where the motor stands is where the DPF is cleaned round The Roe On your driveway, in a work car park, anywhere the vehicle can sit for a while: the job happens with the filter yet bolted on, which is the part most owners do not expect. A diagnostic comes first — running data off the ECU, soot load by proportion and by mass, and a look over of the sensor readings, glow plugs and associated hardware, so other faults are cleared before anything is touched. Soot and ash that a regeneration alone will never move are lifted after that, by a solution fed through the entry point on that vehicle, which spreads inside the filter. Badly blocked filters sometimes need a second pass. Then a regeneration, to drive off what the clean has lifted. That is a monitored drive out of The Roe if you are along, or a static regeneration where the vehicle stands, with the running data read afterwards. Both sets of figures come through by email, so the figures from either end are recorded. The second diagnostic is what confirms the change, puts out the light and lists whatever is still open. ## What a DPF clean will not touch A clean cures one thing: a filter clogged with soot and ash. It does no good for: - sensors, pressure or temperature, flagging a blockage that is not real - the EGR valve held open - the AdBlue system failing - injectors or glow plugs that stop a regeneration starting whatsoever - the turbo passing oil into the filter The first diagnostic is there for precisely that. When one of those proves the fault, you hear about it at the outset rather than once the money has left already. A couple more worth noting. Getting the filter cut out is not a remedy — a vehicle without a functioning DPF cannot pass its MOT and driving it is against the law. And cleaning is sometimes described as DPF renewal: nothing is swapped, your own filter is cleaned in place and sent back into use. ## Figures for DPF cleaning in The Roe Cleaning opens 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. Naming a flat rate would not be straight. We settle it by phone, once the vehicle and its expected needs are established. What you drive and where you are both change it: The Roe itself, over at Pen-rhewl, or farther out across the LL postcode area. Treatment that will not work is not cleaning you pay for, and the scan is what says so. What nonetheless holds is the call-out charge, since the visit was made, the scan was run and the advice was offered. The clean carries a 30-day warranty taking in aftercare, including an engineer heading back out to The Roe if the light reappears inside that window. ## Vehicles we clean, and where we get to near The Roe The filter is treated on the vehicle on all of them: private cars, panel vans and light commercials, heavy goods vehicles, plant machinery, farm vehicles. Nothing is taken anywhere. The Roe is hardly ever a special trip: engineers are working Hen Waliau most weeks, and the same run covers Pen-rhewl, Pengwern and the villages out past Rhuddlan. Even further out around Denbighshire is even so worth ringing about — coverage runs UK-wide, and it is the diary rather than the distance that settles between this day and the next. ## The Roe itself The Roe is a suburban area located on the riverside in Denbighshire, Wales, with a low elevation of around 12 metres. The Roe sits close to the city of St Asaph, which is approximately 0.4 miles away, and is near other nearby places such as Pen-rhewl and Pengwern. The Roe has a population of around 1206 people and predominantly features detached housing. ## Questions The Roe drivers ask about DPF cleaning Can I merely take it for a long drive? Quickly enough, and with the car out of limp mode, yes — sometimes. It wants a long run at motorway speed, not fifteen minutes to Co-op Food and back. How long does the visit take? Bank on typically around 2 hours, with a second clean extending that where the filter is badly blocked. In The Roe, what does it run to? It starts from £299, plus the call-out charge covering the visit, the diagnostic and the advice. Settling it is done by phone, since what you run and where you are both change the figure. Is it essential for me to be there? A spot for the vehicle to sit, for a couple of hours, is all that is required. Not you. Choosing to be there is welcome: the regeneration then is done out on the move, monitored. How soon can someone travel to The Roe? Depending on the calendar, often same-day or next-day is usual. One phone call to 0303 330 1830 and you will hear what the LL area has free. The filter — does it leave the car? On the mobile service, no: the filter is done in place. That job — a filter off, a filter back on — is not a job we do. Suppose the light comes back? An engineer travels back out to The Roe — the 30-day warranty takes in aftercare. ## Have a DPF clean booked around The Roe Ring 0303 330 1830 and set out what the motor is doing: light, limp mode, smoke, whatever it is.
