A technician arrives at your place over in Didling, clears the diesel particulate filter while it is fitted to the car, performs a DPF regeneration, and you end up with the filter you arrived with. The visit runs typically around 2 hours, the clean opens from £299, and the number is fixed over the phone before anyone leaves. Most drivers find us with the light on already, and the car low on power. That is the situation this page is aimed at. ## What to try when the DPF light shows Not the filter, automatically. Main thing to note. That light can come from several faults, not just one, so the visit opens with a diagnostic and not with treatment. Second thing: how you run it between now and then makes a difference. - A long constant run may still be enough, provided the light is amber and the motor runs fine. Costs nothing at all, so try that before booking. - Once the motor is in limp mode, driving will not touch it. The window has shut. - A diesel smell inside, or black smoke under the throttle, is the moment to stop planning long drives and book it in. ## Signs the motor has been sending you The light is belated news. By the time it shows, the symptoms have normally been mounting for some time: - less power, especially going uphill - an engine whose revs will not pull like they did - worse fuel economy - a stop/start that has silently bowed out - a diesel smell in the interior, or smoke under acceleration That is not evidence alone. Alongside the light, it is a fair guess the filter is full. ## Why diesel particulate filters block around Didling The driving that belongs to a rural hamlet like Didling is the least kind sort for a DPF. The school run to Stedham Primary School, Ingram's Green Lane at a halt at half past eight, five minutes to M&S Foodhall, the run to Petersfield — not one bit of it runs long enough or is hot enough for the filter to see through a regeneration. The unburnt soot banks up rather than burning away. Neither is far from Didling: under 10 miles to the Waterlooville Bypass, under 10 miles to Chichester. Neither is on the way to much most weeks, though, so the run that would empty a filter never comes. ## The stage a DPF regeneration can no longer complete It is self-preservation: that is all limp mode amounts to. Pulling power is held down, the revs will not rise, and the regeneration the filter needs can not happen — which is the entire problem, because a proper drive works by starting that regeneration. The usual advice — run it up the motorway — is good, until it is not. The filter requires treatment rather than driving once the vehicle has dropped into limp mode. ## On-site DPF cleaning where the motor stands in Didling Most people do not anticipate this part: the filter stays on. The job takes place with the DPF still fitted to the car — on your front, in a work car park, anywhere the car can stand for a while. The ECU is read first, showing soot load by percentage and by mass, along with a check of sensor feeds, glow plugs and related hardware, so nothing is started while another fault is still possible. Soot and ash that a regeneration on its own will never shift are freed after that, by a cleaning fluid put through the access point on that car, which expands inside the filter. Where the filter is severely clogged, allow for a second pass. What the clean has lifted is then burned off by a regeneration. That is a monitored drive out of Didling if you are there, or a static regeneration where the car sits, with the live data read once done. Both reports go over by email, so the figures from either end are kept. The second scan is what verifies the change, resets the light and notes whatever is still open. ## The failures a DPF clean cannot cure Cleaning cures one thing: a filter choked with soot and ash. It does no good for: - sensors, pressure or temperature, showing a block that is not real - EGR valves that stick open - AdBlue system faults - a regeneration that hardly ever completes, because of glow plugs or injectors - turbo problems, with oil reaching the filter The first check is there for exactly that. If one of those turns out to be the fault, you find out about it up front rather than once the money has changed hands already. Gutting the filter out is not a solution: without a serviceable DPF a vehicle will fail its MOT, and driving it is against the law. DPF renewal is the phrase people type in, though nothing is exchanged — your original filter is cleared in place and returned into use. Two more worth bearing in mind. ## The figure for DPF cleaning in Didling The cleaning begins from £299. A call-out charge is added to every visit, and takes in the call-out itself, the booking, the check and the advice that comes with it. Naming a flat rate would not be truthful. We settle it by phone, once the motor and its probable needs are known. A pair of things change it: what you own, and where you are — Didling itself, across at Elsted Marsh, or farther out across the GU postcode area. A clean that will not work is not cleaning you pay for, and the check is what says so. The call-out charge still holds, because the visit, the diagnostic and the advice have been done. A 30-day warranty takes in aftercare on the clean, and that includes an engineer heading back out to Didling if the light comes back inside the window. ## The vehicles we clean and the ground we reach round Didling The one mobile service takes in private cars, vans of any size and light commercials, HGVs and lorries, plant machinery and farm vehicles, and on every one the filter is treated on the vehicle rather than carried anywhere. Our engineers are along Ingram's Green Lane nearly every week, so Didling is hardly ever a detour, and the same run takes in Elsted Marsh, Elsted and the spots out past Bepton. Coverage is UK-wide, so even further out around West Sussex is even so worth a ring, and what picks between today and tomorrow is the calendar rather than the distance. ## About Didling Didling is a small hamlet in West Sussex, situated inland at an elevation of 82 metres, and is located near the villages of Treyford and Elsted Marsh.

Quickly enough, and with the car out of limp mode, yes — sometimes. Ten minutes to M&S Foodhall and back will not be enough; motorway speed, sustained for a stretch, will. The visit runs how long? Count on typically around 2 hours, with a second clean extending that where the filter is severely loaded. Cost in Didling — what is it? Starting from £299, with a charge for coming out that takes in the check and advice on what to do next. Both the vehicle and where you are change it, which is why settling it is done by phone. Must I be around in person? The motor wants a spot for two hours or so. You need not be in it. The regeneration can be done as a supervised drive if you would prefer to be there. How soon can someone travel to Didling? That hangs on the diary, but it is often same-day or next-day. Call 0303 330 1830 and we will let you what is free across the GU area. The filter — does it come away from the motor? On the mobile service, no: the filter is treated in place. That work — a filter off, a filter back on — is not something we do. What if the light reappears? An engineer heads back out to Didling — the 30-day warranty includes aftercare. ## Organise DPF cleaning around Didling Call 0303 330 1830 and tell us what the motor is doing — light, limp mode, smoke, whatever it is.
