The fitter pulls up at your address in Graveley and sets up. The diesel particulate filter is cleared on the vehicle, a DPF regeneration comes next, and you end up with the filter you arrived with. Reckon on the visit lasting typically around 2 hours. The clean starts from £299, fixed over the phone before anyone travels. Most drivers find us with the light showing, and the vehicle low on power. That is the situation this page is meant for. ## DPF light on? What to do Not the DPF, necessarily. First thing to get straight. Plenty of faults put the identical light on the very same dash, which is why a visit opens with a diagnostic rather than with treatment. The use you manage in the meantime tells. That is the second thing. - A long steady run may still do it, provided the light is amber and the vehicle goes normally. Costs nothing, so have a go at that before calling. - Once the vehicle is in limp mode, a long run will not touch it. The window has gone. - Get it checked rather than running it — diesel in the car, or smoke on acceleration, has gone well past the long-run stage. ## What the motor has been showing you Late news, the light. The symptoms generally build for some time before it appears: - pulling uphill, the power drops away - an engine whose revs will not pull like they did - the fuel consumption is worse - a stop/start that has meekly given up - smoke under acceleration, or a diesel smell in the car None of that is conclusive by itself. Next to the light alongside them, the filter is a fair guess. ## The reason diesel particulate filters block near Graveley Being a village, Graveley throws up precisely the motoring a DPF handles the poorest. The school run to Graveley Primary School, Oak Lane at a halt at half past eight, a few minutes to Sainsbury's, the run to Hitchin — none of it lasts long enough or is hot enough for the filter to finish a regeneration. The unburnt soot collects rather than burning off. Geography does not assist either. The A1(M) is under a mile from Graveley and St Albans is under 15 miles away, so unless something pulls you out that way routinely, weeks slip past without the sustained run that would clear the filter by itself. ## Why limp mode stops a DPF regeneration The motor is defending itself, which is what limp mode amounts to. The real difficulty is that a proper drive works by starting a regeneration, and once in limp mode the revs will not pull and power is capped. The usual advice — get it up the motorway — is good, until it is not. Beyond that point — limp mode — more driving will not do it, and the filter needs cleaning. ## Mobile DPF cleaning where the vehicle stands round Graveley The filter does not come off. That is the bit most people do not expect: the job happens with the DPF yet fixed to the vehicle, on your drive, in a work car park, any place the vehicle can wait for a while. The ECU is interrogated first, reporting soot load by percentage and by weight, along with a review of sensor feeds, glow plugs and related hardware, so nothing is touched while another fault is still open. Next comes the clean itself: cleaning fluid in through the vehicle's own access port, opening out inside the filter and lifting what a regeneration never can. Sometimes a filter is blocked enough to need doing twice. A regeneration follows, burning off what the clean has loosened. Stay with the car and it turns into a monitored drive out of Graveley. Leave it and the regeneration runs on the spot, with running data checked once it is done. Finally the scan runs again — the change verified, the light put out, anything still open written down. Both reports come to you by email, so the numbers are kept. ## When a DPF clean is not the answer A clean cures one thing: a filter clogged with soot and ash. It does little for: - temperature or pressure sensors reporting a blockage that is not there - a stuck-open EGR valve - AdBlue system problems - injectors or glow plugs that prevent a regeneration completing whatsoever - the turbo passing oil into the filter Which is why the diagnostic goes first. Where one of those proves the fault, you hear about it at the outset rather than once the money has changed hands for good. Lastly, two things. A vehicle with the filter hollowed out fails its MOT, and driving it is against the law, so that is no fix. What gets searched for as DPF renewal exchanges nothing: your existing filter is cleaned in place and goes back into service. ## DPF cleaning charges in Graveley A clean begins from £299, with the call-out charge on top of that for every visit — it covers the call-out, the booking, the diagnostics and the advice. Publishing a flat rate would not be truthful. We settle it on the phone, once the motor and its probable needs are known. The vehicle shifts it, and so does the location — Graveley, Little Wymondley, or somewhere further out in the SG postcode area. You are not billed for cleaning that the check says will not work. You nonetheless pay that charge: someone turned up, carried out the diagnostic and offered you the advice. The job carries a 30-day warranty including aftercare, including an engineer heading back out to Graveley if the light reappears inside that time. ## Where we travel round Graveley, and what we clean One call-out service takes in cars, panel vans and light commercials, HGVs, plant machinery and farm vehicles, and on every one the filter is cleaned where it sits rather than carried anywhere. Engineers are along Oak Lane most weeks, so Graveley is hardly ever a detour, and the same run takes in Little Wymondley, Wymondley Bury and the places out past Great Wymondley. Even further out across Hertfordshire is nonetheless worth ringing about — coverage runs UK-wide, and it is the schedule rather than the distance that picks between today and tomorrow. ## About Graveley Graveley is a small village in Hertfordshire, situated on the riverside at an elevation of 96 metres, with semi-detached housing being the predominant type. Graveley lies near the villages of Little Wymondley and Wymondley Bury, and is close to Rooks Nest. Graveley is located approximately 29.8 miles from London and 13.8 miles from St Albans, making it a rural community on the outskirts of the city. ## Questions Graveley drivers ask about DPF cleaning Is a long drive enough on its own? Quickly enough, and with the vehicle out of limp mode, yes — sometimes. It wants a steady run at motorway speed, not fifteen minutes or so to Sainsbury's and back. Roughly how long does it run? Allow typically around 2 hours — heavily clogged filters sometimes take a second pass, which adds to it. Price around Graveley — what is it? It begins from £299, plus the call-out charge covering the visit, the diagnostic and the advice. Settling it is done by phone, since what you drive and where you are both shift the figure. Is it needed for me to be there? You need not stand with it — the vehicle just needs space to stand for a couple of hours. Choosing to be there is welcome: the regeneration then goes out on the open road, monitored. Can someone get to Graveley soon? Depending on the calendar, often same-day or next-day is typical. One call to 0303 330 1830 and you will know what the SG area has available. The filter — does it come off the vehicle? Not on the call-out service — it is cleaned where it stands. Neither lifting a filter off nor putting one back on is work we do. And if the light returns? Included by the 30-day warranty: aftercare, and an engineer heading back to Graveley. ## Organise DPF cleaning around Graveley Whichever it is doing — light, limp mode, smoke — tell us so when you phone 0303 330 1830.
