No workshop, no filter going anywhere. An engineer drives out to your door over in Tretower, clears the diesel particulate filter where it is, carries out a DPF regeneration, and you keep the filter you came with. The visit lasts typically around 2 hours, the clean begins from £299, and the price is fixed over the phone before anyone leaves. If the light is already on and the car is down on power, this page is yours. That is how most owners get to us. ## Your DPF light is on — what then? Not the DPF, always. First thing to get straight. A scan goes before all work, because that same dashboard light has several likely faults behind it. It matters what you get with the vehicle between now and the appointment. - Amber light, vehicle even now driving fine — a long steady run can still shift it alone. Costs zero, and worth trying before you ring anything. - Once the motor is in limp mode, motoring will not shift it. The window has shut. - Diesel smell in the cabin, or black smoke under acceleration — stop booking long drives and get it checked. ## Before the light, what the vehicle was warning you Last news, the light. The symptoms usually grow for some time before it shows: - less power, especially going uphill - the revs no longer rise the way they once did - the fuel consumption is worse - silently, the stop/start bows out - the car stinking of diesel, or smoke when you accelerate None of that is conclusive alone. The light with them suggests a loaded filter. ## Choked diesel particulate filters around Tretower, and the reason Tretower is a village, and the motoring that goes with one is the worst kind for a DPF. Run through a typical week: the local primary school and back, St. John's Close at a standstill before the hour, a quick trip to Home Bargins, a dash to Ebbw Vale Town. None of it there runs long enough or is hot enough to finish a regeneration. What should burn away stays behind. The map does not assist either. The M4 is under 25 miles from Tretower and Newport is under 25 miles away, so unless something pulls you out that way routinely, weeks slip past without the long steady run that might empty the filter by itself. ## Limp mode, and when DPF regeneration gives out It is self-defence: that is all limp mode amounts to. With output capped and the revs kept low, the regeneration the filter needs cannot happen at all. That counts, because setting off one is just what a long run does. Good advice, that motorway run — until the point it is not. The far side of that line — limp mode — more driving will not do it, and the filter wants cleaning. ## DPF cleaning at the vehicle across Tretower On your drive, in a work car park, wherever the car can wait for a while: the job is done with the filter even now fitted on, which is the bit most drivers do not expect. A scan happens first — running data off the ECU, soot load by proportion and by weight, and a review of the sensor feeds, glow plugs and associated parts, so other faults are eliminated before a thing is touched. A cleaning fluid next goes in through the access point on that motor, opening out inside the filter to free soot and ash a regeneration on its own will never budge. Where the filter is heavily blocked, plan on a second pass. What the clean has lifted is then driven off by a regeneration. If you are there, that is carried out as a monitored drive out of Tretower; if not, on the spot where the car stands, with the running data checked once done. Both sets of figures are sent by email, so the figures from either end are recorded. The second check is what proves the change, clears the light and notes whatever is still showing. ## Where treatment is not the fix A filter clogged with soot and ash is the one thing treatment answers. It will not reach: - the wrong signal from a temperature or pressure sensor - the EGR valve held open - a problem in the AdBlue system - failed glow plugs or injectors, so not one regeneration ever completes - oil passing through the filter from a faulty turbo The first check is there for exactly that. Where one of those turns out to be the fault, you find out about it up front rather than once the money has gone already. A couple more worth knowing. Leaving the filter cut out is not a solution — a vehicle without a working DPF cannot pass its MOT and driving it is illegal. And cleaning is sometimes searched for as DPF renewal: nothing is replaced, your original filter is treated in place and sent back into use. ## DPF cleaning prices across Tretower The clean begins from £299. A call-out charge is added to every visit, and takes in the call-out itself, the booking, the check and the advice that follows. Naming a flat rate would not be straight. We settle it on the phone, once the motor and its expected needs are clear. A pair of things shift it: what you run, and where you are — Tretower itself, over at Felindre, or further out within the NP postcode area. Where the check says treatment will not do it, you are not asked to pay for cleaning. What still holds is the call-out charge, since the visit happened, the diagnostic was run and the advice was passed on. Aftercare is taken in by a 30-day warranty: should the light come back within it, an engineer returns to Tretower. ## What we clean, and how far we go round Tretower Whatever it is — car, light van, light commercial, heavy goods vehicle, plant, construction machinery, agricultural machine — the same call-out service applies, and the filter never quits it. Week in week out there is usually someone on St. John's Close, so Tretower seldom means a detour, and Felindre, Cwmdu and the places past Bwlch are on the way. Even further out through Powys is still worth ringing about — coverage is UK-wide, and it is the diary rather than the distance that settles between today and tomorrow. ## The patch around Tretower Tretower is a small village in Powys, Wales, situated on the banks of a river at an elevation of around 90 metres. Tretower lies near the settlements of Pont-y-bryn-hurt, Gaer, and Felindre, and is approximately 22 miles from the city of Newport. Tretower has a population of around 302 people, predominantly living in detached houses. Tretower is located in a rural area, with the nearest major city being Newport and London being around 133 miles away. ## Usual questions on DPF cleaning in Tretower Can I simply take it for a long drive? If you spot it in time, and the motor is not in limp mode, sometimes. That requires motorway speed for a long run, rather than a brief trip to Home Bargins. About how long does it last? It is typically around 2 hours. A badly clogged filter can require a second clean, which adds to that. In Tretower, what does it come to? It begins from £299, plus the call-out charge covering the visit, the diagnostic and the advice. Both the vehicle and where you are shift it, which is why quoting is done by phone. Is it necessary for me to be there? You need not stand with it — the vehicle just wants a spot to sit for a couple of hours. The regeneration can be carried out as a monitored drive if you would sooner be there. Can someone get to Tretower soon? That hangs on the calendar, but it is often same-day or next-day. Phone 0303 330 1830 what is available across the NP area. The filter — does it come away from the car? Cleaned where it stands, on this service, so no. We never lift filters off or fit them back on, in either direction. What if the light comes back? Covered by the 30-day warranty: aftercare, and an engineer coming back to Tretower. ## Setting up a DPF clean in Tretower Whichever it is doing — light, limp mode, smoke — mention so when you phone 0303 330 1830.
