An engineer turns up in a fully fitted mobile unit, clears the DPF unit while it is on the car, carries out a DPF regeneration, and returns the car you began with. 2 hours or thereabouts does for the whole thing, at figures from £299, settled by phone first. ## Expect this from a DPF regeneration visit in Duncton Somewhere for the van to sit. An engine that will run periodically. That's really the whole of it. Beyond that point, it runs itself: - You get a real figure for the load before any cleaning starts — pulled off the engine ECU by weight and percentage, with sensor readings and glow-plug circuit looked at while it's there. - A cleaning agent goes in through the entry point on that car and expands inside the filter, freeing the ash and soot a regeneration alone will never move. - Where it stands is the norm, with a monitored run around Duncton available if you care to come along, and the regeneration takes care of the freed ash whichever you pick. - You see the light go out and the difference proved, with whatever is still showing reported for you. Both diagnostic readouts are forwarded afterwards, so the start and finish figures are documented. ## Where does on-site DPF cleaning take place in Duncton? Anywhere you can stand it and walk away for the couple of hours. That covers most of what people can offer: - A front drive at a home address in Duncton - A company car park - A quiet corner of a compound - A space off Duncton High Street - The Tesco car park, while you get on with something else You're free to go and leave it, and nothing leaves the motor while you're gone. ## Diesel particulate filters around Duncton, and what clogs them Duncton is a rural village, and the motoring that goes with it is what a DPF manages worst. Look at the week: Duncton CofE Junior School and back, A285 crawling at half eight, a few minutes at Tesco, a run to Pulborough. None of it goes on long enough or runs hot enough to see through a regeneration cycle, so the unburnt soot just builds up. Geography worsens it. The Waterlooville Bypass sits under 25 miles from Duncton and Chichester lies under 15 miles away, so unless you have a routine cause to make that run, whole weeks slip past without the long unbroken drive that would scour the filter on its own. The light is the last to arrive. Long before it shows, power has tailed off, the revs have stopped climbing properly, fuel economy has got worse, stop/start has given up silently, and a diesel whiff may have appeared in the cabin. ## On-site DPF cleaning: the failures it answers and the ones it does not A blocked unit is what treatment fixes. All sorts of other failures put that same light on the same dashboard, which is why there's a diagnostic up front and nothing is started until that's complete. A clean will not reach: - Your car being told there is a blockage when there is none - A failed EGR valve - A failure in the AdBlue system, on the models that use one - Plugs or injectors stopping a regeneration from running at all - A turbo problem putting oil through the DPF Well before any cleaning gets going is when you hear, rather than once the money has been taken. Driving without a functioning DPF is against the law and the vehicle will not clear an MOT, so having the unit cut out fixes nothing. Nor is anything exchanged: what people type in as DPF renewal is the same unit, cleared where it sits and returned to service. ## Will a long run shift it on its own? Worth a go before you ring: a filter that's only just started to fill up will often come good. under 25 miles separates Duncton and the Waterlooville Bypass, and that is the run to take, running the pace even. The longer route into Chichester works too. Ten minutes to Sutton and home does not. An on-site clean becomes the practical next move once the light is on and limp mode has arrived, because a long run will no longer reach it. ## What on-site DPF cleaning works out at around Duncton You are starting at from £299 for call-out DPF treatment. You also pay a call-out fee on each visit. It covers the travel, the booking, the diagnostic scan and the guidance you are handed. The motor, and what the DPF actually needs, both change what a job adds up to — which is why no flat rate is listed. Tell us what you drive and roughly whereabouts you sit — Duncton itself, across at Barlavington, or elsewhere in the GU postcode area — and you'll be given the price prior to anyone setting off. A 30-day warranty backs the work, aftercare covered. An engineer drives back to Duncton should the DPF warning light return during that time. ## Which vehicles do we treat DPFs on round Duncton? All of these are given the same on-site service: - Your vehicle - Light commercials - HGVs - Building-site and plant machinery - Farm vehicles and machinery A workshop of ours is not where the job is done. Your door in Duncton is, with the DPF treated in place on every one of them. Our own workshop steps in where an engine will not start: once you or your local garage have taken the unit off and a courier has carried it in, it is cleared within 24 hours. Neither option includes taking a unit off or fitting one again. ## Duncton and the GU patch There's generally a van on A285 most weeks, so Duncton is seldom a detour. The same run includes Barlavington and East Lavington, and the smaller places over past Sutton and Byworth. Wider afield across West Sussex, the call is still worth making. You are not held up by distance. Coverage extends nationwide, and it is the local schedule that governs whether it is today or tomorrow. ## What Duncton drivers ask about call-out DPF cleaning How much time does the job run? You are in for around two hours, plus more where the DPF needs going over again. Around Duncton, what does mobile DPF cleaning come to? The base figure is from £299, with the call-out, diagnostic and advice charged for separately as a call-out. The car and your address both change the price, so we quote over the phone. Can you get to my house or my work? Right across Duncton and the wider West Sussex area, home or work. Nothing is taken off. Wherever the car happens to be standing is where the cleaning takes place. Can you get to Duncton today? You will typically be offered the same-day or the next, subject to what is already in. Across the GU postcode area, availability changes daily, so phone 0303 330 1830 and we will say where it is. What if the problem is not the filter after all? You'll meet the call-out charge either way, because the technician has come out, scanned the car and told you what's genuinely wrong. No charge is raised for a job that was not done. The DPF warning light comes back — what then? The 30-day warranty includes aftercare, and that means a repeat visit to Duncton. How many months does a clean last? That depends on how the car is run afterwards. Short trips over to Barlavington and back don't do much. A sustained run out past Chichester, or along the Waterlooville Bypass, does far more. ## Arrange mobile DPF cleaning in Duncton A call to 0303 330 1830 and an account of the fault is all it needs.
