An engineer turns up at your address across Garnlydan, treats the diesel particulate filter while it is attached to the motor, performs a DPF regeneration, and you keep the filter you arrived with. Nobody leaves until the number is agreed by the phone. The visit takes typically around 2 hours and the clean starts from £299. Most drivers find us with the light showing, and the motor down on power. That is the position this page is written for. ## The DPF light is on. What now? Not the DPF, necessarily. Opening thing to say. A diagnostic happens before all work, because that same dashboard light has a number of candidate faults behind it. How the car is driven in the meantime counts too. - A long constant run may still manage it, provided the light is amber and the motor drives fine. Costs nothing, so have a go at that before booking. - That window has shut once the car has dropped into limp mode. Driving will not do it now. - Stop planning long drives and get it checked if the cabin smells of diesel or there is black smoke when you press on. ## Before the light, what the car was showing you Symptoms have usually been growing for some time before the light so much as arrives. Last news, in other words: - pulling uphill, the power tails off - an engine whose revs will not pull like they did - consumption that is worse than it used to be - stop/start silently packing in - a diesel smell in the cabin, or smoke under the throttle Any one of those, taken alone, is not proof. Next to the light, it is a fair guess the filter is full. ## Why diesel particulate filters clog around Garnlydan Being a residential suburb, Garnlydan throws up just the driving a DPF handles the poorest. None of it goes on long enough or gets hot enough for the filter to complete a regeneration: the school run to the local primary school, Llangynidr Road crawling at the morning rush, a few minutes to Morrisons, the run to Ebbw Vale Town. The soot banks up rather than burning off. Save when you have a routine reason to drive out to the M4, under 25 miles from Garnlydan, or over to Newport under 25 miles away, weeks slip past without a long steady stint. Geography is unhelpful. ## DPF regeneration, and the stage limp mode kills it It is self-defence: that is all limp mode amounts to. A proper drive works by starting a regeneration, and that is just what limp mode blocks: power limited, revs pinned, no regeneration possible. So the usual advice to get it up the motorway is good advice, until the day it is not. The filter needs treatment rather than road work once the car has gone into limp mode. ## Call-out DPF cleaning where the vehicle stands across Garnlydan On your front, in a work car park, wherever the car can stand for a few hours: the job is done with the filter even now bolted on, which is the bit most drivers do not anticipate. First a scan. Running ECU data, the soot load as a percentage and as a mass, the sensor readings, the glow plugs, the related components — all of it taken before a thing is started. A cleaning fluid after that goes in through the entry point on that motor, spreading inside the filter to loosen soot and ash a regeneration on its own will never move. Badly loaded filters sometimes require a second pass. Next, a regeneration burns off everything the clean lifted. That is a monitored drive out of Garnlydan if you are along, or a static regeneration where the motor sits, with the live data checked once done. Finally the diagnostic runs again — the change confirmed, the light reset, anything still showing written down. Both reports reach you by email, so the numbers are kept. ## When a DPF clean is not the solution Only one fault is answered by a clean: the filter clogged with ash and soot. It does no good for: - the wrong reading from a temperature sensor - a jammed EGR valve - the AdBlue system failing - a regeneration that hardly ever runs, because of glow plugs or injectors - oil passing through the filter from a failing turbo That is what the first diagnostic is for. If it proves to be one of those, you are told before any work gets going rather than after you have paid anything. Lastly, two things. A vehicle with the filter cut out fails its MOT, and driving it is against the law, so that is no fix. What gets looked up as DPF renewal swaps nothing: your filter is cleared in place and goes back into work. ## What DPF cleaning runs to across Garnlydan Treatment starts from £299, with the call-out charge on top of that for every visit — it pays for the call-out, the booking, the diagnostics and the advice. Once we have what you run, and broadly what the filter will want, the price gets settled on the phone. A single price for every job would not be straight. A pair of things move it: what you drive, and where you are — Garnlydan itself, out at Beaufort Hill, or otherwise out across the NP postcode area. If the diagnostic writes treatment out, there is nothing to pay for it. What nonetheless stands is the call-out charge, since the visit happened, the scan was run and the advice was passed on. A 30-day warranty includes aftercare on the job, and that includes an engineer coming back out to Garnlydan if the light returns inside the window. ## Where we get to near Garnlydan, and what we clean The filter is done where it sits on all of them: cars, vans of any size and light commercials, HGVs, construction and plant machinery, agricultural vehicles. Nothing is taken anywhere. Garnlydan is seldom a special trip: engineers are along Llangynidr Road most weeks, and the same run takes in Beaufort Hill, Rassau and the places out past Brynmawr. It is the calendar, not the distance, that picks whether it is one day or the next, and coverage runs UK-wide — so call even from further out across Blaenau Gwent. ## Garnlydan itself Garnlydan is a suburban area situated lakeside in Blaenau Gwent, with a mix of terraced housing and a relatively small population of around 1178 residents. Garnlydan sits at an elevation of 396 metres, overlooking the surrounding landscape and nearby communities such as Carmeltown and Beaufort. Garnlydan is located near the town of Beaufort Hill and is approximately 17.6 miles from Newport, making it a commuter base for the city. Garnlydan's lakeside setting provides a unique environment for its residents. ## Questions Garnlydan drivers ask about DPF cleaning Can I merely take it for a long drive? If you get it early enough, and the motor is not in limp mode, sometimes. It wants a sustained run at motorway speed, not five minutes or so to Morrisons and back. Broadly how long does it take? Plan on typically around 2 hours — badly clogged filters sometimes need a second pass, which extends it. Cost across Garnlydan — what is it? Beginning from £299, with a charge for the call-out that takes in the scan and advice on what to do next. The vehicle and your address both shift the figure, so we price on the phone. Is it needed for me to be present? No. The car requires space to sit for a couple of hours; you need not stand with it. Choosing to be there is no problem: the regeneration then is done out on the move, monitored. When can someone get to Garnlydan? That depends on the diary, but it is often same-day or next-day. Call 0303 330 1830 and we will tell you what is available across the NP area. Does the filter come away from the vehicle? Not on the call-out service — it is treated where it sits. Neither job — a filter off, a filter back on — is not a job we do. Suppose the light reappears? Covered by the 30-day warranty: aftercare, and an engineer heading back to Garnlydan. ## Book a DPF clean in Garnlydan Call 0303 330 1830 and set out what the vehicle is doing: the light, limp mode, smoke, whatever it is.
