The technician pulls up at your door across Highway and sets up. The diesel particulate filter is cleared on the car, a DPF regeneration follows, and you end up with the filter you started with. You'll have a number by phone before anyone goes, the clean beginning from £299, and the visit taking typically around 2 hours. The light is on already and the vehicle is low on power — that is how we usually come across people, and what this page is about. ## What to check when the DPF light comes on First thing: it is not automatically the unit. Cleaning is not where a visit begins. A scan is — a number of faults show up as the same signal. Second thing: how you drive it between now and then matters. - Amber light, vehicle even now driving normally — a long even run can still shift it alone. Costs zero, and worth a try before you book anything. - Once the car is in limp mode, driving will not reach it. The window has closed. - Get it seen to rather than using it — diesel in the car, or smoke on the throttle, has gone beyond the long-run stage. ## The car has been telling you already Last news, the light. The symptoms generally build for weeks before it shows: - less power, especially climbing uphill - revs that will not climb the way they once did - fuel economy turning worse - the stop/start quietly bowing out - a diesel smell in the cabin, or smoke under hard acceleration Alone, none of that is conclusive. It is a fair assumption the filter is loaded once the light is showing too. ## Why diesel particulate filters choke near Highway Being a residential suburb, Highway produces just the driving a DPF handles the poorest. The school run to Courthouse Junior School, Pinkneys Road at a standstill at the morning rush, five minutes to Budgens, the dash to Furze Platt — none of it lasts long enough or gets hot enough for the filter to finish a regeneration. What should burn off remains. The A404(M) sits under a mile from Highway, St Albans under 25 miles off, and unless something carries you out that way routinely, whole weeks go by without the sustained run that clears a unit. Geography does not help. ## The moment a DPF regeneration can no longer happen Limp mode is the car looking after itself. Pulling power is held down, the revs will not rise, and the regeneration the filter requires can no longer run — which is the whole problem, because a long drive works by setting off that regeneration. Sensible advice, that motorway run — right up until the point it is not. In limp mode you are past that line: cleaning is what will help, not more miles. ## DPF cleaning at the car in Highway Most people do not expect this part: the filter remains. The job takes place with the DPF still fitted to the motor — on your front, in a work car park, any place the motor can sit for a couple of hours. Nothing is started until other faults are cleared. That means a check first: running data off the ECU, soot load by proportion and by weight, and a review of the sensor readings, glow plugs and related parts. Then the cleaning. A solution goes in through the access port on that motor and opens out inside the filter, freeing the soot and ash a regeneration by itself will never shift. Sometimes a filter is blocked enough to need doing twice. What the clean has freed is then cleared by a regeneration. Ride along with the car and it becomes a monitored drive out of Highway. Leave it and the regeneration runs in place, with real-time data verified once it is done. Then a second diagnostic, verifying the change, putting out the warning light and listing anything still logged. Both sets of figures are emailed over, so the before and after figures are on record. ## When a DPF clean is not the answer Treatment cures one thing: a filter clogged with soot and ash. It does little for: - the wrong figure from a temperature sensor - a stuck-open EGR valve - an AdBlue system fault - a regeneration that simply never starts, because of glow plugs or injectors - a turbo putting oil through the filter Finding that out is the first check's whole job. Where one of those turns out to be the fault, you learn of it up front rather than once the money has left altogether. Cutting the filter out is not a remedy: without a functioning DPF a vehicle will fail its MOT, and driving it is illegal. DPF renewal is the phrase people search for, though nothing is exchanged — your original filter is cleaned in place and put back into use. Two more worth knowing. ## The cost for DPF cleaning in Highway The treatment starts from £299. A call-out charge is added to every visit, and pays for the call-out itself, the booking, the check and the advice that comes with it. Once we are told what you run, and broadly what the filter will want, the price gets settled by phone. A single price for every job would not be straight. Two things change it: what you run, and where you are — Highway itself, over at Boyn Hill, or otherwise out within the SL postcode area. Where the check says treatment will not work, you are not charged for treatment. Because the visit, the scan and the advice have taken place, the call-out charge still applies. Aftercare is covered by a 30-day warranty: should the light reappear within it, an engineer comes back to Highway. ## Vehicles we clean, and where we travel round Highway Whatever it is — private car, light van, light commercial, lorry, plant, construction machinery, agricultural vehicle — the same on-site service applies, and the filter never quits it. The same trip that keeps technicians on Pinkneys Road most weeks covers Highway, Boyn Hill, Cox Green and the places beyond Maidenhead. Ring anyway from farther out through Berkshire. Coverage reaches UK-wide, and the slot you get hangs on the diary rather than how far away you are. ## The ground around Highway Highway is a suburban area in Berkshire, situated inland at an elevation of around 55 metres. Highway lies within the commuter belt, approximately 26.9 miles from London and 23.7 miles from St Albans, with nearby places including Tittle Row, Boyn Hill, and Pinkneys Green. Highway has a population of around 7355 people, predominantly living in semi-detached housing. ## Things Highway drivers ask about DPF cleaning Can I merely take it for a long drive? Early enough, and with the car out of limp mode, yes — sometimes. A long run at motorway speed is what it needs — not fifteen minutes to Budgens and back. The visit runs how long? That is typically around 2 hours, though a badly loaded filter can require cleaning twice, which runs on. Cost across Highway — what is it? The call-out charge takes in the visit, the scan and the advice; the clean itself begins from £299. Both the vehicle and where you are change it, which is why pricing is done by phone. Is it essential for me to be present? No. The car requires somewhere to stand for a couple of hours; nobody expects you to stand with it. The regeneration can be carried out as a watched drive if you would prefer to be there. Travelling to Highway — how soon? It is often same-day or next-day, depending on what is already in the schedule. One phone call to 0303 330 1830 and you will hear what the SL area has free. Does the filter come away from the car? Treated where it sits, on this service, so no. That job — a filter off, a filter back on — is not a job we do. Suppose the light returns? Included by the 30-day warranty: aftercare, and an engineer heading back to Highway. ## Put a DPF clean booked in Highway Ring 0303 330 1830 and say what the car is doing — a light, limp mode, smoke, whatever it is.
