No workshop, no filter coming off. A fitter comes to your door over in The Clos, clears the diesel particulate filter in place, performs a DPF regeneration, and you hold on to the filter you started with. Budget for the visit lasting typically around 2 hours. The clean starts from £299, settled by the phone before anyone leaves. Most people find us with the light on already, and the vehicle short of power. That is the position this page is written for. ## The DPF light is on. What then? It might not be the unit at all. That is the main thing. Plenty of faults put the very same light on the same dash, which is why a visit starts with a diagnostic rather than with a clean. How the motor is handled in the meantime makes a difference too. - A long steady run may even now be enough, provided the light is amber and the vehicle goes fine. Costs zero, so try that before ringing. - Motor already dropped into limp mode — that window has shut. A drive will not touch it now. - Diesel smell in the cabin, or black smoke under acceleration — stop arranging long drives and get it looked at. ## Before the light, what the car was showing you Symptoms have usually been growing for weeks before the light ever shows. Late news, in other words: - dropping away on power, above all uphill - revs that will not climb the way they always did - fuel economy going worse - stop/start quietly giving up - diesel in the interior, or smoke on the way up through the gearbox On its own, none of that is evidence. It is a fair bet the filter is loaded once the light is showing too. ## What chokes diesel particulate filters around The Clos The motoring that goes with a small village like The Clos is the poorest type for a DPF. The school run to the local primary school, Salem Road at a halt at the morning rush, five minutes to the local shops, the run to Whitland — nothing of it runs long enough or is hot enough for the filter to see through a regeneration. Instead of burning away, the soot banks up. Neither is far from The Clos: under 25 miles to the M4, under 50 miles to Swansea. Neither is on the way to anything most weeks, though, so the drive that would clear a filter hardly ever happens. ## DPF regeneration, and the moment limp mode kills it It is self-preservation: that is all limp mode means. The whole catch is that a long drive works by starting a regeneration, and in limp mode the revs will not climb and power is held down. Good advice, that motorway run — up until the moment it is not. In limp mode you are the far side of that stage: cleaning is what will work, not more miles. ## On-site DPF cleaning where the vehicle stands round The Clos On your front, in a work car park, any place the motor can wait for a couple of hours: the job is done with the filter even now fixed on, which is the bit most people do not anticipate. The ECU is taken first, showing soot load by proportion and by actual weight, along with a look over of sensor feeds, glow plugs and connected hardware, so nothing is touched while another fault is still open. Then the clean. A cleaning fluid is fed in through the access point on that motor and opens out inside the filter, loosening the soot and ash a regeneration by itself will never budge. A second pass is sometimes needed on severely blocked filters. Next, a regeneration clears everything the clean freed. That is a monitored drive out of The Clos if you are along, or a static regeneration where the vehicle stands, with the running data verified once done. Both reports go over by email, so the figures from either end are on record. The second diagnostic is what verifies the change, clears the light and lists whatever is still showing. ## The faults a DPF clean cannot fix A filter blocked with soot and ash is the one thing a clean fixes. It will not touch: - the wrong reading from a pressure or temperature sensor - the EGR valve jammed open - a fault in the AdBlue system - a regeneration that simply never starts, because of glow plugs or injectors - oil passing through the filter from a faulty turbo The first scan is there for precisely that. Proving to be one of them means finding out it before work gets going, not after handing over anything. DPF renewal is what people look up, but no part is exchanged: the filter you have is treated where it sits and returned to use. Nor is having it gutted a fix, since the MOT then fails and driving becomes unlawful. Two more things worth bearing in mind. ## The figure of DPF cleaning around The Clos Every visit attracts a call-out charge — coming out to you, making the booking, running the scan and giving the advice. The clean itself begins from £299. The figure is settled on the phone, once we have the vehicle and what the filter is likely to need. No flat rate could be truthful. Whereabouts you are matters as much as what you drive: The Clos itself, Gellywen close by, or further out within the SA postcode area. Treatment that will not work is not treatment you pay for, and the scan is what says so. You still pay that charge: someone travelled, ran the diagnostic and gave you the advice. The work carries a 30-day warranty taking in aftercare, including an engineer travelling back out to The Clos if the light reappears inside that time. ## Where we travel near The Clos, and what we clean Whatever it is — estate, panel van, light commercial, lorry, plant, construction machinery, agricultural vehicle — the same call-out service holds, and the filter never quits it. Week in week out there is already someone on Salem Road, so The Clos hardly ever means a journey of its own, and Gellywen, Llangynin and the places past Meidrim come with it. Ring anyway from further out through Carmarthenshire. Coverage reaches UK-wide, and the day you are given depends on the diary rather than how far away you are. ## The patch around The Clos The Clos is a small locality in Carmarthenshire, situated on the riverside at a low elevation of around 40 metres. The Clos is located near several nearby villages, including Gellywen, Meidrim, and Llangynin, and is approximately 30 miles from the city of Swansea. The Clos has a population of around 280 people and is characterised by predominantly detached housing. ## Questions The Clos drivers ask about DPF cleaning Will a long drive sort it? Soon enough, and with the motor out of limp mode, yes — sometimes. Five minutes to the local shops and back will not be enough; motorway speed, kept for a stretch, will. How long does the visit last? Reckon on typically around 2 hours, with a second clean extending that where the filter is heavily clogged. What does it run to in The Clos? A clean begins from £299, and the call-out charge on top covers the visit, the check and the advice. The vehicle and your address both change the figure, so we quote on the phone. Must I be present in person? No. The vehicle requires somewhere to sit for a couple of hours; you do not need to stand with it. If you would sooner come along, the regeneration can be run as a watched drive instead. When can someone get to The Clos? You are offered often same-day or next-day, though it depends what is now in the schedule. Phone 0303 330 1830 what is available across the SA area. Does the filter come away from the vehicle? Treated where it sits, on this service, so no. That job — a filter off, a filter back on — is not work we do. Suppose the light returns? An engineer heads back out to The Clos — the 30-day warranty covers aftercare. ## Set up DPF cleaning in The Clos Talk us through what the car is doing on 0303 330 1830, whether that is smoke, limp mode or the light.
