Your motor will not be taken away and the filter doesn't leave it. A technician turns up at your address over in Southwick, treats the diesel particulate filter still on the car and carries out a DPF regeneration. Allow for the visit taking typically around 2 hours. The clean starts from £299, settled by the phone before anyone travels. The light is on already and the car is down on power — that is how we normally come across people, and precisely what this page is about. ## The DPF light is on. What now? Not the DPF, automatically. Main thing to get straight. Treatment is not where a visit starts. A diagnostic is — plenty of faults register as the same warning. How the motor is handled in the meantime matters too. - A long even run may yet manage it, provided the light is amber and the motor goes as normal. Costs nothing at all, so have a go at that before ringing. - That window has shut once the vehicle has slipped into limp mode. Motoring will not do it now. - A diesel smell in there, or black smoke under hard acceleration, is the point to stop planning long drives and ring. ## Signs the vehicle has been showing you Belated news, the light. The symptoms generally grow for weeks before it appears: - power tailing off, especially climbing uphill - an engine whose revs will not rise as before - fuel economy going worse - stop/start silently bowing out - smoke under hard acceleration, or a diesel smell in the car Any one of those, taken by itself, is not conclusive. Alongside the light, it is a fair guess the filter is full. ## What clogs diesel particulate filters near Southwick For a DPF, the poorest motoring is the type you get across a coastal town such as Southwick. The school run to Glebe Primary School, Grange Road at a halt at half past eight, a few minutes to Little Waitrose, the hop to the nearest station — not one bit of it runs long enough or gets hot enough for the filter to complete a regeneration. Unburnt soot that should burn off builds up instead. Except when you have a standing need to get out to the M23, under 25 miles from Southwick, or across to Brighton and Hove under 5 miles away, whole weeks go by without a long steady stint. Geography is against you. ## Why limp mode stops a DPF regeneration The vehicle is protecting itself, which is what limp mode means. The whole problem is that a sustained drive works by setting off a regeneration, and once in limp mode the revs will not pull and power is limited. The common advice — take it up the motorway — is sound, until it is not. In limp mode you are past that stage: a clean is what will work, not more miles. ## Where the car stands is where the DPF is done in Southwick Most owners do not expect this bit: the filter stays on. The job is done with the DPF still fitted to the motor — on your drive, in a work car park, wherever the car can wait for a couple of hours. First a diagnostic. Running ECU data, the soot load as a percent and as a weight, the sensor feeds, the glow plugs, the related parts — all of it read before anything is cleaned. Soot and ash that a regeneration by itself will never move are lifted second, by a cleaning solution fed through the access port on that motor, which spreads inside the filter. A second pass is sometimes needed on severely blocked filters. What the clean has lifted is then burned off by a regeneration. That is a monitored drive out of Southwick if you are along, or a static regeneration where the car sits, with the real-time data verified afterwards. Both sets of figures are sent by email, so the figures from either end are recorded. The second diagnostic is what proves the change, puts out the light and lists whatever is still outstanding. ## What a DPF clean will not cure A clean fixes one thing: a filter clogged with soot and ash. It does little for: - temperature or pressure sensors flagging a blockage that is not there - EGR valves that hang open - AdBlue system problems - injectors or glow plugs that prevent a regeneration starting at all - turbo failure, with oil reaching the filter Finding that out is the first diagnostic's whole job. Where one of those is the fault, you hear about it at the outset rather than once the money has gone for good. Lastly, two things. A vehicle with the filter gutted cannot pass its MOT, and driving it is an offence, so that is no remedy. What gets searched for as DPF renewal swaps nothing: your existing filter is cleared in place and goes back into service. ## What DPF cleaning costs around Southwick The clean begins from £299. A call-out charge covers every visit, and pays for the call-out itself, the booking, the check and the advice that comes with it. The number is fixed on the phone, once we have the vehicle and what the filter is going to need. No flat rate could be honest. The motor changes it, and so does the postcode — Southwick, Southern Cross, or somewhere otherwise out in the BN postcode area. Where the check says a clean will not do it, you are not asked to pay for cleaning. Because the visit, the scan and the advice have taken place, the call-out charge even so holds. If the light reappears inside that period, an engineer comes back out to Southwick — the clean comes with a 30-day warranty taking in aftercare. ## Vehicles we clean, and where we reach near Southwick Whatever it is — private car, light van, light commercial, HGV, plant, construction machinery, farm vehicle — the one call-out service stands, and the filter never leaves it. Nearly every week there is already someone on Grange Road, so Southwick hardly ever means a journey of its own, and Southern Cross, Mile Oak and the villages past Shoreham-by-Sea are on the way. Coverage is UK-wide, so farther out through West Sussex is nonetheless worth a phone call, and what decides between today and tomorrow is the schedule rather than the distance. ## Southwick itself Southwick is a coastal town in West Sussex, situated near the city of Brighton and Hove, with a population of around 23208 people. Southwick lies on the coast at a low elevation of 6 metres, close to nearby places such as Southern Cross, Portslade Village, and Portslade-by-Sea. Southwick has a predominance of semi-detached housing, reflecting its development as a residential area. Southwick is also within commuting distance of London, being approximately 46.7 miles away. ## What Southwick drivers want to know about DPF cleaning Can I just take it for a long drive? If you get it early enough, and the vehicle is not in limp mode, sometimes. A sustained run at motorway speed is what it needs — not fifteen minutes flat to Little Waitrose and back. How long does the visit run? That is typically around 2 hours, though a heavily loaded filter can require cleaning twice, which runs on. How much does it run to in Southwick? It opens from £299, plus the call-out charge taking in the visit, the diagnostic and the advice. Quoting is done by phone, since what you drive and where you sit both change the figure. Is it essential for me to be around? You need not stand with it — the vehicle just requires somewhere to sit for a couple of hours. If you would sooner come along, the regeneration can be done as a supervised drive instead. How soon can someone travel to Southwick? It is often same-day or next-day, depending on what is now in the schedule. Call 0303 330 1830 and we will tell you what is free across the BN area. Does the filter come away from the vehicle? Treated where it sits, on this service, so no. And neither does getting a filter off nor fitting one back on is work we do. Suppose the light returns? Aftercare sits inside the 30-day warranty, and that includes an engineer coming back to Southwick. ## Setting up a DPF clean around Southwick Talk us round what the vehicle is doing on 0303 330 1830, whether that is smoke, limp mode or the light.
