A fitter arrives at your place across Downgate, cleans the diesel particulate filter while it is still on the vehicle, carries out a DPF regeneration, and you end up with the filter you started with. Reckon on the visit taking typically around 2 hours. The clean begins from £299, settled on the phone before anyone sets off. Most people find us with the light on already, and the motor low on power. That is the position this page is meant for. ## The DPF light is on. What then? First thing: it is not necessarily the DPF. Plenty of faults put the very same light on the identical dash, which is why a visit begins with a check rather than with a clean. The motoring you get in the meantime tells. That is the next thing. - Amber light, vehicle still driving normally — a long constant run can even now clear it alone. Costs nothing, and worth a try before you ring anything. - That window has shut once the vehicle has slipped into limp mode. Motoring will not help now. - A diesel smell in the car, or black smoke under acceleration, is the point to stop planning long drives and ring. ## The motor has been telling you already The light is late news. By the time it appears, the symptoms have normally been building for a while: - power falling off, above all pulling uphill - revs that will not pull the way they once did - the fuel consumption is down - stop/start without a word packing in - a diesel smell in the car, or smoke under the throttle That is not evidence alone. With the light with them, the filter is a fair bet. ## What chokes diesel particulate filters round Downgate For a DPF, the worst use is the sort you get around a rural hamlet such as Downgate. Run through a normal week: Upton Cross Academy and back, B3254 at a standstill before nine, a five-minute run to Aldi, a hop to Liskeard. Nothing there runs long enough or runs hot enough to see through a regeneration. Instead of clearing, the soot banks up. The map does not oblige either. The M5 is under 50 miles from Downgate and Plymouth is under 25 miles away, so unless something takes you out that way regularly, whole weeks go by without the long unbroken run that could clear the filter on its own. ## Limp mode, and when DPF regeneration stops It is self-preservation: that is all limp mode amounts to. A long drive works by triggering a regeneration, and that is exactly what limp mode rules out: power capped, revs kept low, no regeneration on offer. Sound advice, that motorway run — until the day it is not. In limp mode you are past that line: treatment is what will do it, not more road work. ## The motor stays in place for on-site DPF cleaning in Downgate On your driveway, in a work car park, anywhere the motor can wait for a few hours: the job takes place with the filter even now fitted on, which is the bit most drivers do not anticipate. Nothing is cleaned until other faults are cleared. That means a check first: real-time data off the ECU, soot load by percentage and by weight, and a look over of the sensor readings, glow plugs and related hardware. After that comes the clean itself: cleaning fluid in through the motor's own entry point, expanding inside the filter and loosening what a regeneration never can. Where the filter is heavily loaded, plan on a second pass. A regeneration is next, clearing what the clean has loosened. If you are there, that is run as a monitored drive out of Downgate; if not, in place where the vehicle waits, with the running data read afterwards. Finally the check runs again — the change confirmed, the light reset, anything still open noted. Both sets of figures reach you by email, so the numbers are kept. ## When a DPF clean is not the fix Only one fault is answered by treatment: the filter choked with ash and soot. It does little for: - sensors, pressure or temperature, flagging a block that is not real - an EGR valve held open - AdBlue system failures - worn glow plugs or injectors, so never a regeneration ever runs - a turbo passing oil through the filter The first scan is there for precisely that. If it is found to be one of those, you are told before any work gets going rather than after you have paid anything. Hollowing the filter out is not a solution: without a functioning DPF a vehicle fails its MOT, and driving it is illegal. DPF renewal is the wording people look up, though nothing is exchanged — your original filter is cleaned in place and returned into use. Two more worth bearing in mind. ## DPF cleaning prices in Downgate A call-out charge holds whatever the outcome, and pays for the visit, the booking fee, the diagnostic and the advice given. Treatment itself begins from £299. The price is settled by the phone, once we know the vehicle and what the filter is apt to need. No flat rate could be straight. Two separate things move it: what you drive, and where you are — Downgate itself, across at Upton Cross, or farther out within the PL postcode area. Where the scan says cleaning will not do it, you are not charged for a clean. The call-out charge still applies, because the visit, the diagnostic and the advice have been done. Aftercare is taken in by a 30-day warranty: should the light return within it, an engineer comes back to Downgate. ## Where we reach around Downgate, and what we clean The filter is done in place on all of them: cars, vans and light commercials, HGVs, construction and plant machinery, agricultural vehicles. Nothing is moved anywhere. The same round that has technicians on B3254 most weeks picks up Downgate, Upton Cross, Sutton and the places beyond Pensilva. Farther out across Cornwall is nonetheless worth phoning about — coverage runs UK-wide, and it is the calendar rather than the distance that picks between today and tomorrow. ## About Downgate Downgate is a small hamlet in Cornwall, situated inland at an elevation of 216 metres, and is located near the villages of Dunslea and Upton Cross.
