Your vehicle isn't taken anywhere and the filter doesn't leave it. An engineer arrives at your door over in Swallowfield, cleans the diesel particulate filter on the car and performs a DPF regeneration. Reckon on the visit taking typically around 2 hours. The clean starts from £299, agreed on the phone before anyone travels. The light is on already and the motor is down on power — that is how we normally meet people, and what this page deals with. ## What to check when the DPF light is on The DPF is not always what is wrong, and that comes first. A scan happens before all work, because that same dash light has several candidate faults behind it. How the motor is driven in the meantime makes a difference too. - Motor yet driving fine on an amber light — have a go at a long even run first. It costs nothing and often clears the filter without help. - A drive will not shift it now — limp mode means that window has by then gone. - Stop arranging long drives and get it seen to if the car reeks of diesel or there is black smoke when you accelerate. ## Before the light, what the car was telling you Symptoms have usually been mounting for some time before the light even appears. Last news, in other words: - less power, above all going uphill - an engine whose revs will not climb as they should - worse fuel use - silently, the stop/start bows out - the interior reeking of diesel, or smoke when you pull away None of that is evidence alone. With the light, it is a fair guess the filter is blocked. ## Blocked diesel particulate filters round Swallowfield, and the reason For a DPF, the least kind motoring is the kind you get across a village such as Swallowfield. The school run to Lambs Lane Primary School, Charlton Lane at a crawl at half eight, ten minutes to Wellington Farm Shop, the run to Mortimer — not one bit of it lasts long enough or gets hot enough for the filter to complete a regeneration. What should burn away remains. Save when you have a regular need to head out to the M4, under 3 miles from Swallowfield, or across to Winchester under 50 miles away, weeks go by without a long unbroken run. Geography is against you. ## Limp mode, and when DPF regeneration stops Limp mode is the vehicle defending itself. A sustained drive works by setting off a regeneration, and that is just what limp mode prevents: power capped, revs held down, no regeneration possible. The usual advice — take it up the motorway — is good, right until it is not. The filter wants treatment rather than driving once the vehicle has gone into limp mode. ## Where the vehicle stands is where the DPF is cleaned round Swallowfield Nothing comes off the car. That surprises people. The DPF stays bolted where it is and the work is done around it, on a drive, in a works car park, anywhere it can sit for a few hours. The ECU is read first, showing soot load by proportion and by actual weight, along with a look over of sensor feeds, glow plugs and related components, so nothing is touched while another fault is still possible. Next comes the clean itself: a cleaning solution in through the vehicle's own access port, expanding inside the filter and loosening what a regeneration will not. Severely loaded filters sometimes require a second pass. What the clean has loosened is then driven off by a regeneration. If you are there, that is carried out as a monitored drive out of Swallowfield; if not, on the spot where the motor stands, with the live data read afterwards. Then a second scan, 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 kept. ## Where treatment is not the solution A filter blocked with soot and ash is the one thing cleaning cures. It will not touch: - pressure sensors reporting a blockage that is not there - an EGR valve stuck open - AdBlue system failures - a regeneration that simply never starts, because of glow plugs or injectors - the turbo passing oil into the filter The first diagnostic is there for exactly that. You are told before all work begins, not after you have handed over, should it turns out to be one of those. DPF renewal is what people type in, but no part is swapped: the filter you own is treated where it sits and sent back into service. Nor is having it hollowed out a solution, since the MOT then fails and driving becomes illegal. Two more things worth bearing in mind. ## What DPF cleaning costs across Swallowfield Any visit takes a call-out charge — coming out to you, setting up the booking, doing the scan and passing on the advice. The clean itself begins from £299. Once we are told what you drive, and broadly what the filter will want, the price gets fixed by phone. A single price for all would not be honest. The motor shifts it, and so does the postcode — Swallowfield, Riseley, or a spot farther out in the RG postcode area. Where the diagnostic says cleaning will not work, you are not billed for a clean. What nonetheless stands is the call-out charge, since the visit happened, the check was done and the advice was given. Aftercare is taken in by a 30-day warranty: should the light come back within it, an engineer comes back to Swallowfield. ## Vehicles we clean, and where we travel around Swallowfield The one mobile service covers cars, vans and light commercials, HGVs, plant and construction machinery and agricultural machinery, and on every one the filter is treated where it sits rather than moved anywhere. Our engineers are along Charlton Lane week in week out, so Swallowfield is rarely a special trip, and the same run picks up Riseley, Beech Hill and the places out past Spencers Wood. Further out through Berkshire is nonetheless worth ringing about — coverage runs UK-wide, and it is the schedule rather than the distance that decides between this day and the next. ## About Swallowfield Swallowfield is a small village in Berkshire, situated on the banks of the River Loddon at an elevation of around 55 metres.

Sometimes, if you get it early enough and the vehicle has not fallen into limp mode. It wants a sustained run at motorway speed, not five minutes flat to Wellington Farm Shop and back. Does the visit run long? Allow typically around 2 hours — badly blocked filters sometimes need a second pass, which adds to it. Around Swallowfield, what does it run to? Starting from £299, with a charge for coming out that covers the scan and advice on what to do next. Both the vehicle and where you are change it, which is why quoting happens by phone. Must I be around in person? The motor wants a place for two hours or so. You do not need to be in it. The regeneration can be done as a supervised drive if you would rather be there. Travelling to Swallowfield — how soon? You are looking at often same-day or next-day, though it depends what is currently in the schedule. Call 0303 330 1830 and you will learn what is available across the RG area. Is the filter removed from the vehicle? On the on-site service, no: the filter is treated in place. We never lift filters off or bolt them back on, whichever way. And if the light comes back? Aftercare comes inside the 30-day warranty, and that includes an engineer coming back to Swallowfield. ## Book a DPF clean around Swallowfield Walk us about what the vehicle is doing on 0303 330 1830, whether that is smoke, limp mode or the light.
