No workshop, no filter coming off. A fitter comes to your address over in Cross Coombe, cleans the diesel particulate filter where it is, carries out a DPF regeneration, and you keep the filter you came with. Nobody travels until the price is agreed on the phone. The visit takes typically around 2 hours and the clean starts from £299. If the light is on already and the vehicle is down on power, this page is the right one. That is how most drivers end up here. ## Your DPF light is showing — what next? Not the DPF, automatically. First thing to note. Cleaning is not where a visit starts. A scan is — plenty of faults show up as the same light. It counts what you manage with the motor between now and the booking. - A long steady run may even now do it, provided the light is amber and the motor runs fine. Costs zero, so have a go at that before booking. - Motor already fallen into limp mode — that window has gone. A drive will not shift it now. - Diesel smell in the cabin, or black smoke under the throttle — stop planning long drives and get it checked. ## The car has been telling you already By the time the light shows, things have normally been deteriorating for some time. It is belated news: - power tailing off, particularly going uphill - revs that will not rise the way they used to - fuel use that is worse than it used to be - stop/start without a word packing in - smoke under the throttle, or a diesel smell inside None of that is proof on its own. With the light, it is a fair assumption the filter is loaded. ## The cause diesel particulate filters clog around Cross Coombe Cross Coombe is a coastal area, and the motoring that belongs to one is the least kind type for a DPF. Look at an ordinary week: St Agnes Academy and home, Quay Road at a crawl before the hour, a quick trip to Co-op Food, a hop to Redruth. None of it there lasts long enough or gets hot enough to finish a regeneration. The soot that should clear collects instead. Neither is far from Cross Coombe: over 50 miles to the M5, under 10 miles to Truro. Neither is on the way to anything most weeks, though, so the journey that would clear a filter never comes. ## DPF regeneration, and the stage limp mode kills it The car is looking after itself, which is what limp mode is. The real problem is that a proper drive works by triggering a regeneration, and under limp mode the revs will not rise and power is limited. So the usual advice to take it up the motorway is sensible advice, right until it is not. In limp mode you are past that point: cleaning is what will help, not more road work. ## Where the car stands is where the DPF is done in Cross Coombe The filter does not come off. That is the bit most owners do not see coming: the job takes place with the DPF even now fixed to the vehicle, on your drive, in a work car park, anywhere the car can sit for a few hours. First a diagnostic. Running ECU data, the soot load as a percentage and as a mass, the sensor feeds, the glow plugs, the connected parts — all of it taken before a thing is started. Soot and ash that a regeneration alone will never budge are freed second, by a cleaning fluid passed through the entry point on that car, which expands inside the filter. A second pass is sometimes called for on severely blocked filters. A regeneration is next, driving off what the clean has freed. Stay with the vehicle and it turns into a monitored drive out of Cross Coombe. Park it and the regeneration is done in place, with running data verified once it is done. Finally the check runs again — the change confirmed, the light reset, anything still outstanding logged. Both sets of figures come to you by email, so the numbers are on record. ## The problems a DPF clean cannot cure One thing is what treatment fixes — a filter clogged with soot and ash. It does no good for: - temperature or pressure sensors showing a blockage that is not there - EGR valves that hang open - a failure in the AdBlue system - injectors or glow plugs that stop a regeneration completing whatsoever - a turbo pushing oil through the filter Which is why the diagnostic comes first. When one of those is the fault, you hear about it in advance rather than once the money has left already. A couple more worth noting. Leaving the filter hollowed out is not a remedy — a vehicle without a serviceable DPF cannot pass its MOT and driving it is against the law. And cleaning is sometimes described as DPF renewal: nothing is replaced, your original filter is cleaned in place and sent back into use. ## Prices for DPF cleaning around Cross Coombe Treatment starts from £299, with the call-out charge on top of that for every visit — it takes in the call-out, the booking, the checks and the advice. No flat rate would be truthful, so the number is agreed over the phone once we have the vehicle and what the filter is going to need. The car moves it, and so does the location — Cross Coombe, St Agnes, or anywhere otherwise out in the TR postcode area. If the scan rules treatment out, there is no charge to pay for it. You still pay that charge: someone turned up, did the scan and gave you the advice. Aftercare is covered by a 30-day warranty: should the light reappear within it, an engineer heads back to Cross Coombe. ## The vehicles we clean and the patch we cover round Cross Coombe Whatever it is — estate, 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 by then someone on Quay Road, so Cross Coombe rarely means a special trip, and St Agnes, Peterville and the spots past Trevellas follow. Coverage is UK-wide, so further out around Cornwall is even so worth a phone call, and what settles between today and tomorrow is the diary rather than the distance. ## A word on Cross Coombe Cross Coombe is a small coastal locality in Cornwall, situated near the town of St Agnes and the village of Peterville. Cross Coombe lies at an elevation of 82 metres, overlooking the surrounding coastline and countryside. Cross Coombe is characterised by its predominantly detached housing stock, reflecting its rural setting and relatively small population of around 323 residents. ## What Cross Coombe drivers wonder about DPF cleaning Can I merely take it for a long drive? It might, provided you spot it early and limp mode has not set in. Fifteen minutes to Co-op Food and back will not be enough; motorway speed, sustained for a stretch, will. About how long does it run? Bank on typically around 2 hours, with a second clean extending that where the filter is heavily blocked. Around Cross Coombe, what does it come to? Starting from £299, with a charge for travelling that pays for the check and advice on what to do next. Quoting is done by phone, since what you run and where you live both move the price. Do I have to be present? A spot for the vehicle to stand, for a couple of hours, is all that is needed. Not you. Ride along if you prefer, and the regeneration turns into a supervised drive. Getting to Cross Coombe — how soon? That hangs on the diary, but it is often same-day or next-day. Phone 0303 330 1830 and we will say to you what is open across the TR area. Will the filter be removed? On the on-site service, no: the filter is cleaned in place. Neither lifting a filter off nor fitting one back on is work we do. And if the light comes back? An engineer comes back out to Cross Coombe — the 30-day warranty takes in aftercare. ## Arrange DPF cleaning in Cross Coombe Phone 0303 330 1830 and describe what the car is doing — light, limp mode, smoke, whatever it is.
