A technician pulls up in a fully fitted mobile unit, treats the DPF unit while it is still attached to the car, runs a DPF regeneration, and returns the car you started with. It takes around two hours, opens from £299, and the figure is settled over the phone prior to anybody leaving. ## What a call-out DPF regeneration visit around Westminster looks like All the van requires is somewhere to stand, and the car needs a motor that'll tick over now and then. After that, it runs the same four steps every time: - Nothing gets touched until we know what we're facing. A diagnostic scan pulls the engine ECU and comes back with the soot load as a percentage and by weight, and the sensor readings, the glow plugs and connected components get checked at the same time. - A cleaning agent passes in through the injection point on that vehicle and expands inside the filter, freeing the ash and soot a regeneration alone will never budge. - A burn cycle then drives off whatever the clean has freed. That'll take place on the spot, or out on a monitored trip out of Westminster if you like coming along. - A closing scan verifies the change, clears the warning light, and writes down any stored codes still outstanding. Nothing about the figures is left unproven — the readings from the start and the finish both come by email. ## Locations a DPF cleaning visit can happen round Westminster Anywhere the vehicle can stand for the couple of hours. Which generally means one of these: - Your own front drive in Westminster - A company car park - An unused corner of a yard - A corner off Parliament Street - The AP Food Express car park round the corner while you do something else No standing around with the car, and no DPF being taken from it while you are gone. ## Why diesel particulate filters clog around Westminster It's the day-to-day driving rather than the filter, and in a cathedral city such as Westminster that motoring is the worst type for it. Soot that should burn away builds up instead, because the filter never sees through a regeneration run — not on the run to St Matthew's School, Westminster, not sat on Bridge Street at half eight, not on ten minutes to AP Food Express, and not on the hop to London Charing Cross. Geography worsens it. The M4 sits under 10 miles from Westminster and London sits under 3 miles away, so unless you have a routine need to do that journey, whole weeks go by without the long steady drive that would clear the filter on its own. You'll most likely have picked up on something already. A smell of diesel inside, black smoke when you put your foot down, pull falling off, revs that won't climb, worse economy, and the stop/start giving up without a word. That builds for a while before the light shows. ## What mobile DPF cleaning cures, and what it does not If soot has blocked your unit, treatment is the cure. It is not the fix to everything that puts the identical light on an instrument panel, and the check is what tells the two apart before anything is started. Treatment will not fix: - Faulty sensors reporting a restriction that is not there - A jammed EGR valve - An AdBlue system failure - Faulty plugs or injectors, so no regeneration ever starts - Oil working into the unit from a failing turbo Where any of them proves to be the fault, we say so in advance rather than after you have handed over. DPF renewal is the usual search term, though no part is replaced — the original unit is cleaned on the vehicle and sent back into use. Hollowing the filter out is no fix either, since the MOT then cannot be passed and the road use becomes illegal. ## Try a long drive before booking Worth a go before you ring: a unit that's only just started to clog will often sort itself. From Westminster that means the M4, under 10 miles away, at an even speed, or the scenic way round to London — not another five minutes to Richmond and back. Once the light's on and you're in limp mode, that window has shut and an on-site clean is what's left. ## What call-out DPF cleaning works out at in Westminster Where mobile DPF regeneration opens is from £299. You also meet a call-out charge on any visit. It takes in the travelling, the booking, the diagnostic and the guidance you are handed. The car, and what the unit actually needs, both change what a given job works out at — which is why no set price is listed. Westminster itself, across at Whitehall, or the far side of the SW1A postcode area — where you are counts, and so does the motor. Both are agreed prior to anyone setting off. Aftercare is not charged separately; it falls under the 30-day warranty the work includes. An engineer comes back to Westminster should the DPF warning light come on again during that window. ## Vehicles we clean DPFs on round Westminster All of these are given the same on-site visit: - Your vehicle - Vans and light goods vehicles - HGVs - Building-site and plant machinery - Farm and agricultural machinery The DPF is treated in place on each one, at your place in Westminster rather than at our premises. If the car will not fire up at all, the mobile option cannot assist: the DPF comes off by you or your local garage, travels to our own workshop by carrier, and is cleaned within 24 hours of arrival. You will have to find a garage to take the unit off and put it back, on either of them. ## Westminster and the SW1A patch Our technicians are on Bridge Street most weeks, so Westminster is seldom a special trip. The same route takes in Whitehall and Lambeth, and the smaller places over past Richmond and Stoneleigh. Phone anyway if you are further out across Greater London. Coverage extends nationwide; what settles whether it is today or tomorrow is the local schedule rather than the distance. ## Mobile DPF cleaning questions from around Westminster How much time is the appointment? You are facing about 2 hours, plus more where the filter needs treating again. What will on-site DPF cleaning come to me around Westminster? It begins from £299, and there's a call-out fee on top taking in the visit, the scan and the guidance. No flat rate would hold, since the motor and the mileage both shift the price. Can you travel to my house or my workplace? Either, right across Westminster or the surrounding Greater London area. The DPF doesn't leave the motor — it's treated exactly where the car stands. How soon can you make it to Westminster? Frequently the day itself or the next, according to what is already booked. Ring 0303 330 1830 and we'll tell you straight away what's available across the SW1A patch. Is there anything to pay if it proves not to be the DPF? Regardless that charge stands, since it covers the journey, the check and the guidance. What you will not receive is a bill for cleaning that was never done. Am I looked after if the warning light comes on again? An engineer drives back to Westminster. Aftercare of that sort is what the 30-day warranty extends to. How many months before I need it doing again? It hinges on how you run it from then on. Short trips round Whitehall and back don't do much. A longer run out past London, or down the M4, does far more. ## Have on-site DPF cleaning arranged in Westminster Whatever the car is showing, report it to us on 0303 330 1830.
