The fitter turns up at your place in Cortachy and starts. The diesel particulate filter is cleaned still on the vehicle, a DPF regeneration comes next, and you hold on to the filter you arrived with. Nobody leaves until the number is settled on the phone. The visit runs typically around 2 hours and the clean starts from £299. Most owners find us with the light on already, and the vehicle low on power. That is the position this page is aimed at. ## DPF light on? What happens next The DPF is not necessarily what is at fault, and that comes first. A scan happens before all cleaning, because that same dashboard light has several possible faults behind it. The driving you manage in the meantime tells. That is the other thing. - A long constant run may still be enough, provided the light is amber and the motor runs fine. Costs nothing at all, so attempt that before ringing. - That window has closed once the motor has slipped into limp mode. A drive will not help now. - Diesel smell in the interior, or black smoke under acceleration — stop arranging long drives and get it seen to. ## Signs the motor has been showing you By the time the light arrives, things have generally been slipping for a while. It is last news: - pulling uphill, the power tails off - the revs no longer rise the way they used to - the fuel economy is worse - a stop/start that has quietly given up - a diesel smell in the car, or smoke under hard acceleration By itself, none of that is proof. Next to the light alongside them, the filter is a fair bet. ## Why diesel particulate filters choke near Cortachy The motoring that belongs to a rural hamlet like Cortachy is the poorest kind for a DPF. The school run to the local primary school, Cortachy Bridge at a standstill at half past eight, ten minutes to Co-op Food, the run to the nearest station — not one bit of it runs long enough or gets hot enough for the filter to see through a regeneration. Instead of burning off, the soot load builds up. The M90 lies under 50 miles from Cortachy, Dundee under 25 miles off, and unless something takes you out that way often, full weeks slip past without the sustained run that empties a unit. Geography does not assist. ## DPF regeneration, and the moment limp mode stops it It is self-defence: that is all limp mode means. With power held down and the revs kept low, the regeneration the filter wants can never run at all. That matters, because starting one is just what a long run does. So the common advice to take it up the motorway is sensible advice, up until it is not. The filter needs treatment rather than more driving once the motor has slipped into limp mode. ## Where the car stands is where the DPF is done in Cortachy Most drivers do not expect this bit: the filter stays put. The job happens with the DPF yet bolted to the car — on your drive, in a work car park, any place the motor can stand for a while. The ECU is taken first, reporting soot load by proportion and by actual weight, along with a check of sensors, glow plugs and related parts, so nothing is started while another fault is still possible. Then the clean. A solution is injected through the access point on that vehicle and spreads inside the filter, loosening the soot and ash a regeneration on its own will never shift. Severely loaded filters sometimes take a second pass. Then a regeneration, to clear what the clean has freed. If you are there, that is carried out as a monitored drive out of Cortachy; if not, in place where the vehicle stands, with the real-time data read once done. Finally the check runs again — the change confirmed, the light reset, anything still open written down. Both reports arrive with you by email, so the numbers are kept. ## When a DPF clean is not the fix A filter clogged with soot and ash is the one thing cleaning fixes. It will not touch: - the wrong reading from a temperature or pressure sensor - a jammed EGR valve - an AdBlue system problem - faulty glow plugs or injectors, so no regeneration ever starts - the turbo putting oil into the filter Finding that out is the first diagnostic's whole job. Where one of those proves the fault, you find out about it at the outset rather than once the money has left altogether. Lastly, two things. A vehicle with the filter hollowed out cannot pass its MOT, and driving it is an offence, so that is no remedy. What gets searched for as DPF renewal exchanges nothing: your existing filter is cleared in place and goes back into use. ## DPF cleaning charges around Cortachy A clean opens from £299, with the call-out charge on top of that for every visit — it covers the call-out, the booking, the scans and the advice. Once we know what you own, and roughly what the filter will want, the number gets settled by phone. A single price for every job would not be honest. Two separate things move it: what you run, and where you are — Cortachy itself, over at Dykehead, or otherwise out within the DD postcode area. Where the scan says a clean will not help, you are not billed for cleaning. The call-out charge still applies, because the visit, the check and the advice have taken place. A 30-day warranty takes in aftercare on the clean, and that includes an engineer travelling back out to Cortachy if the light reappears inside the time. ## What we clean, and how far we travel round Cortachy Whatever it is — private car, van, light commercial, heavy goods vehicle, plant, construction machinery, agricultural machine — the one on-site service applies, and the filter never departs it. Nearly every week there is already someone on Cortachy Bridge, so Cortachy hardly ever means a special trip, and Dykehead, Northmuir and the places past Kirriemuir come with it. Call anyway from even further out across Angus. Coverage extends UK-wide, and the date you are offered hangs on the calendar rather than how far away you are. ## About Cortachy Cortachy is a small hamlet situated on the riverside in Angus, with a population of around 84 residents. Cortachy sits at an elevation of 143 metres, surrounded by rolling countryside and nearby settlements such as Dykehead and Pearsie. Cortachy is characterized by its predominantly detached housing stock, reflecting its rural setting. Cortachy is located approximately 18 miles from Dundee, the nearest city, and is part of a wider network of small communities in the area. ## What Cortachy drivers ask about DPF cleaning Does a long run clear it? It can, provided you get it in time and limp mode has not set in. It wants a sustained run at motorway speed, not ten minutes or so to Co-op Food and back. How long does the visit take? That is typically around 2 hours, though a badly loaded filter can require cleaning twice, which adds time. What does it cost across Cortachy? Beginning from £299, with a charge for travelling that takes in the scan and advice on what to do next. The vehicle and your address both shift the figure, so we settle it on the phone. Is it needed for me to be present? No. The vehicle wants space to wait for a couple of hours; nobody expects you to stand with it. Choosing to be there is no problem: the regeneration then goes out on the open road, monitored. Can someone get to Cortachy soon? You are in for often same-day or next-day, though it depends what is now in the schedule. One phone call to 0303 330 1830 and you will hear what the DD area has available. Is the filter removed from the car? Not on the mobile service — it is done where it stands. Lifting a filter off or fitting one back on count as anything something we do either way. Suppose the light comes back? The 30-day warranty includes aftercare, including an engineer coming back to Cortachy. ## Book a DPF clean in Cortachy Phone 0303 330 1830 and describe what the car is doing — the light, limp mode, smoke, whatever it is.
