The engineer pulls up at your address in Swiss Cottage and gets to work. The diesel particulate filter is cleaned still on the car, a DPF regeneration comes next, and you hold on to the filter you started with. Nobody leaves until the price is agreed over the phone. The visit lasts typically around 2 hours and the clean starts from £299. Most owners find us with the light already on, and the vehicle low on power. That is the situation this page is meant for. ## DPF light on? What to do It may not be the DPF whatsoever. That is the main thing. A check happens before the treatment, because that same panel light has a number of possible faults behind it. Second thing: how you drive it between now and then makes a difference. - Vehicle yet driving fine on an amber light — attempt a long steady run first. It costs zero and often shifts the filter without assistance. - That window has shut once the vehicle has slipped into limp mode. Driving will not get there now. - Diesel smell in the interior, or black smoke under the throttle — stop booking long drives and get it seen to. ## Before the light, what the car was warning you By the time the light shows, things have normally been deteriorating for weeks. It is belated news: - falling off on power, particularly uphill - an engine whose revs will not climb as they should - fuel use that is worse than it used to be - stop/start quietly packing in - smoke under acceleration, or a diesel smell in there None of that is conclusive by itself. It is a fair guess the filter is loaded once the light is showing too. ## The reason diesel particulate filters clog around Swiss Cottage Swiss Cottage is a residential suburb, and the day-to-day driving that goes with one is the poorest sort for a DPF. Think about an ordinary week: Holy Trinity CofE Primary School, NW3 and home again, Avenue Road at a crawl before the hour, a five-minute run to Save More, a run to South Hampstead. None of it there lasts long enough or is hot enough to see through a regeneration. Instead of burning away, the unburnt soot banks up. Neither is distant from Swiss Cottage: under 5 miles to the M1, under 5 miles to Westminster. Neither is on the way to much most weeks, though, so the drive that would clear a filter never happens. ## DPF regeneration, and the point limp mode kills it Limp mode is the motor looking after itself. Power is held down, the revs will not rise, and the regeneration the filter needs can not complete — which is the entire difficulty, because a sustained drive works by starting that regeneration. Running it up the motorway is the usual advice, and it works up to a point. Once the vehicle is in limp mode you are past that stage, and the filter requires a clean rather than more driving. ## Where the motor stands is where the DPF is done across Swiss Cottage Nothing is taken from the motor. That throws people. The DPF stays bolted where it is and the work goes on around it, on a forecourt, in a works car park, anywhere it can stand for a few hours. Nothing is touched until other faults are cleared. That requires a scan first: live data off the ECU, soot load by proportion and by weight, and a look over of the sensor feeds, glow plugs and associated components. Soot and ash that a regeneration alone will never move are loosened next, by a cleaning solution passed through the access port on that car, which expands inside the filter. A second pass is sometimes called for on heavily blocked filters. What the clean has lifted is then burned off by a regeneration. That is a monitored drive out of Swiss Cottage if you are along, or a static regeneration where the vehicle waits, with the live data verified afterwards. Then a second scan, verifying the change, clearing the warning light and logging anything still showing. Both reports are emailed over, so the before and after figures are on record. ## What a DPF clean will not touch One thing is what treatment answers — a filter blocked with soot and ash. It does little for: - sensors, pressure, showing a blockage that is not real - a jammed EGR valve - an AdBlue system failure - failed glow plugs or injectors, so no regeneration ever runs - a turbo putting oil through the filter That is what the first diagnostic is for. You are told before all work starts, not after you have paid, if it turns out to be one of those. Hollowing the filter out is not a solution: without a working DPF a vehicle will fail its MOT, and driving it is an offence. DPF renewal is the term people look up, though nothing is exchanged — your original filter is treated in place and put back into use. Two more worth bearing in mind. ## DPF cleaning charges in Swiss Cottage A clean begins from £299, with the call-out charge on top of that for every visit — it takes in the call-out, the booking, the checks and the advice. No single flat rate would be truthful, so the figure is settled by the phone once we are told the vehicle and what the filter is going to need. The car changes it, and so does the address — Swiss Cottage, Belsize Park, or anywhere farther out in the NW postcode area. Where the scan says treatment will not help, you are not billed for cleaning. The call-out charge even so holds, because the visit, the diagnostic and the advice have happened. Aftercare is covered by a 30-day warranty: should the light reappear within it, an engineer comes back to Swiss Cottage. ## The vehicles we clean and the patch we take in around Swiss Cottage Cars, panel vans and light commercials, HGVs, plant machinery, farm vehicles — one on-site service across all of them, and on all of them the filter is done in place rather than moved anywhere. Nearly every week there is by then someone on Avenue Road, so Swiss Cottage rarely means a journey of its own, and Belsize Park, Frognal and the spots past Richmond follow. It is the schedule, not the distance, that settles whether it is this day or the next, and coverage reaches UK-wide — so ring still from farther out through Greater London. ## The ground around Swiss Cottage Swiss Cottage is a suburban area in northwest London, situated near the River Thames and the Regent's Canal. Swiss Cottage sits at an elevation of 59 metres, close to the city centre and neighbouring areas such as South Hampstead and Belsize Park. Swiss Cottage is predominantly composed of flat dwellings, accommodating a population of approximately 17,250 residents. Swiss Cottage is well connected to central London, being just 3.1 miles from the city centre and 3.5 miles from Westminster. ## Common questions on DPF cleaning around Swiss Cottage Is a long drive enough alone? It may, provided you catch it early and limp mode has not begun. A sustained run at motorway speed is what it needs — not ten minutes or so to Save More and back. Broadly how long does it take? It is typically around 2 hours. A severely clogged filter can take a second clean, which adds to that. What does it run to across Swiss Cottage? It starts from £299, plus the call-out charge paying for the visit, the check and the advice. We settle it on the phone, because the vehicle and your address both change the figure. Must I be there in person? A spot for the vehicle to stand, for a couple of hours, is all that is required. Not you. Come along if you like, and the regeneration becomes a monitored drive. Can someone get to Swiss Cottage soon? It is often same-day or next-day, depending on what is already in the schedule. Ring 0303 330 1830 and we will say to you what is free across the NW area. Will the filter be lifted off? Not on the mobile service — it is done where it stands. We do not take filters off or bolt them back on, in either direction. Suppose the light returns? Taken in by the 30-day warranty: aftercare, and an engineer coming back to Swiss Cottage. ## Book a DPF clean across Swiss Cottage However it is doing — light, limp mode, smoke — mention so when you phone 0303 330 1830.
