No workshop, no filter going anywhere. A fitter travels to your door over in Craig-llwyn, cleans the diesel particulate filter in place, runs a DPF regeneration, and you keep the filter you started with. Nobody leaves until the figure is settled by the phone. The visit runs typically around 2 hours and the clean starts from £299. If the light is showing and the car is down on power, this page is for you. That is how most drivers get to us. ## Your DPF light is lit — what then? First thing: it is not always the DPF. Plenty of faults put the very same light on the very same dashboard, which is why a visit starts with a scan rather than with a clean. The motoring you get in the meantime tells. That is the second thing. - Vehicle yet driving fine on an amber light — have a go at a long constant run first. It costs zero and frequently clears the filter without help. - Once the vehicle is in limp mode, driving will not reach it. The window has shut. - Diesel smell in the cabin, or black smoke under the throttle — stop arranging long drives and get it looked at. ## What the car has been showing you Last news, the light. The symptoms tend to mount for weeks before it appears: - power tailing off, above all pulling uphill - an engine whose revs will not climb like they did - fuel use that is worse than it was - a stop/start that has silently bowed out - the interior stinking of diesel, or smoke when you accelerate None of that is evidence on its own. It is a fair guess the filter is full once the light is showing too. ## The explanation diesel particulate filters clog around Craig-llwyn Being a rural hamlet, Craig-llwyn generates precisely the driving a DPF handles worst. None of it goes on long enough or gets hot enough for the filter to complete a regeneration: the school run to Trefonen CofE Primary School, Sandrock Lane crawling at the morning rush, five minutes to M&S Simply Food, the hop to Gobowen. Instead of burning away, the unburnt soot builds up. Neither is a long way from Craig-llwyn: under 50 miles to the M54, under 25 miles to Wrexham. Neither is on the way to much most weeks, though, so the journey that would empty a filter simply never gets made. ## Limp mode, and when DPF regeneration stops working It is self-preservation: that is all limp mode is. With power capped and the revs held, the regeneration the filter wants can never run at all. That tells, because triggering one is just what a motorway run does. The standard advice — get it up the motorway — is good, until it is not. Once the car is in limp mode you are past that line, and the filter requires cleaning rather than driving. ## On-site DPF cleaning where the motor stands across Craig-llwyn The filter does not leave it. That is the bit most owners do not see coming: the job happens with the DPF even now fitted to the motor, on your driveway, in a work car park, wherever the vehicle can sit for a while. A check goes first — live data off the ECU, soot load by percentage and by mass, and a check of the sensor feeds, glow plugs and related hardware, so other faults are cleared before a thing is cleaned. After that comes the clean itself: solution in through the car's own entry point, spreading inside the filter and lifting what a regeneration cannot. A second pass is sometimes needed on severely clogged filters. A regeneration is next, clearing what the clean has loosened. Ride along with the car and it is done as a monitored drive out of Craig-llwyn. Drop it and the regeneration goes in place, with real-time data verified once it is done. Then a second check, verifying the change, clearing the warning light and logging anything still logged. Both reports are emailed, so the before and after figures are on record. ## What a DPF clean will not touch Treatment fixes one thing: a filter blocked with soot and ash. It does little for: - the wrong figure from a temperature sensor - a failed EGR valve - AdBlue system faults - a regeneration that hardly ever runs, because of glow plugs or injectors - the turbo putting oil into the filter Which is why the check comes first. Proving to be one of them means learning it before any work begins, not after paying a penny. Hollowing the filter out is not a fix: without a working DPF a vehicle cannot pass its MOT, and driving it is against the law. DPF renewal is the wording people type in, though nothing is exchanged — your original filter is treated in place and sent back into use. Two more worth noting. ## DPF cleaning charges around Craig-llwyn The treatment starts from £299. A call-out charge covers every visit, and pays for the call-out itself, the booking, the check and the advice that goes with it. Publishing a flat rate would not be truthful. We agree it by phone, once the motor and its likely needs are known. What you drive and where you are both change it: Craig-llwyn itself, out at Pentre-cefn, or further out in the SY postcode area. Treatment that will not work is not treatment you pay for, and the check is what says so. You nonetheless pay that charge: someone came out, carried out the diagnostic and gave you the advice. A 30-day warranty covers aftercare on the clean, and that includes an engineer travelling back out to Craig-llwyn if the light reappears inside the period. ## Where we get to round Craig-llwyn, and what we clean A single call-out service takes in cars and estates, vans of any size and light commercials, HGVs and lorries, plant and construction machinery and farm vehicles, and on every one the filter is cleaned where it sits rather than carried anywhere. Nearly every week there is already someone on Sandrock Lane, so Craig-llwyn hardly ever means a journey of its own, and Pentre-cefn, Tyn-y-coed and the places past Trefonen are on the way. Even further out around Shropshire is even so worth a call — coverage is UK-wide, and it is the diary rather than the distance that picks between one day and the next. ## Craig-llwyn itself Craig-llwyn is a small hamlet in Shropshire, situated inland at an elevation of 285 metres, and is located near the Welsh border. Craig-llwyn lies close to several nearby settlements, including Croesau Bach, Pentre-cefn, and Nant-y-gollen, and is approximately 15 miles from Wrexham. Craig-llwyn is characterised by its predominantly detached housing stock and a small population of around 296 residents. Craig-llwyn is also relatively distant from major urban centres, with London being around 157 miles away. ## Questions Craig-llwyn drivers ask about DPF cleaning Does a long run shift it? Soon enough, and with the vehicle out of limp mode, yes — sometimes. That requires motorway speed for a long stretch, rather than a brief trip to M&S Simply Food. The visit takes how long? Bank on typically around 2 hours, with a second clean lengthening that where the filter is heavily loaded. How much does it cost around Craig-llwyn? Beginning from £299, with a charge for coming out that takes in the diagnostic and advice on what to do next. Settling it is done by phone, since what you own and where you are both shift the number. Have I got to be present? Nobody expects you to stand with it — the vehicle just requires a spot to sit for a couple of hours. The regeneration can be carried out as a watched drive if you would rather come along. When can someone travel to Craig-llwyn? Depending on the diary, often same-day or next-day is usual. Ring 0303 330 1830 and you will learn what is free across the SY area. Does the filter come away from the vehicle? It is done where it is, on the mobile service. Getting a filter off or bolting one back on come to anything work we do whichever way. Suppose the light reappears? An engineer heads back out to Craig-llwyn — the 30-day warranty covers aftercare. ## Book a DPF clean in Craig-llwyn Talk us about what the motor is doing on 0303 330 1830, whether that is smoke, limp mode or the light.
