Your vehicle is not taken away and the filter doesn't leave it. An engineer turns up at your address over in Citadel, treats the diesel particulate filter still on the vehicle and runs a DPF regeneration. Nobody travels until the figure is agreed over the phone. The visit lasts typically around 2 hours and the clean starts from £299. If the light is already on and the vehicle is down on power, this page is for you. That is how most owners end up here. ## Your DPF light is on — what next? First thing: it is not necessarily the unit. A number of faults put the very same light on the very same dash, which is why a visit begins with a diagnostic rather than with cleaning. It tells what you get with the vehicle between now and the visit. - Worth a shot before you call anything: amber light, motor driving normally, just one constant run, no cost. - A drive will not reach it now — limp mode means that window has now shut. - Diesel smell in the cabin, or black smoke under hard acceleration — stop booking long drives and get it checked. ## What the motor has been telling you The light is last news. By the time it shows, the symptoms have generally been mounting for weeks: - less power, particularly going uphill - revs that will not pull the way they once did - worse fuel economy - the stop/start quietly bowing out - the interior reeking of diesel, or smoke when you pull away That is not evidence by itself. With the light alongside them, the filter is a fair assumption. ## Why diesel particulate filters clog round Citadel The driving that goes with a residential suburb like Citadel is the poorest kind for a DPF. A regeneration wants time and heat, and has neither: not on the school run to the local primary school, not on Shore Street at half eight, not on a few minutes to Morrisons, and not on the run to Inverness. Instead of burning off, the unburnt soot collects. Neither is a long way from Citadel: over 50 miles to the M90, under a mile to Inverness. Neither is on the way to anywhere most weeks, though, so the drive that would scour a filter never happens. ## DPF regeneration, and the stage limp mode ends it The car is defending itself, which is what limp mode is. Power is limited, the revs will not pull, and the regeneration the filter requires can no longer complete — which is the entire problem, because a long drive works by setting off that regeneration. Running it up the motorway is the standard advice, and it stands up to a limit. The filter requires a clean rather than road work once the motor has gone into limp mode. ## The car stays in place for mobile DPF cleaning across Citadel The filter does not come off. That is the detail most people do not expect: the job takes place with the DPF even now bolted to the motor, on your driveway, in a work car park, anywhere the vehicle can stand for a few hours. The ECU is read first, showing soot load by percentage and by actual weight, along with a look over of sensors, glow plugs and connected parts, so nothing is cleaned while another fault is still in play. Then the clean. A solution is injected through the access point on that car and opens out inside the filter, freeing the soot and ash a regeneration on its own will never move. Where the filter is severely blocked, expect a second pass. Then a regeneration, to burn off what the clean has lifted. Either it runs as a monitored drive out of Citadel, with you along, or it goes where the vehicle waits and the live data is verified afterwards. A second diagnostic confirms the change, clears the warning light and logs anything still showing. Both sets of figures are sent over, so you keep the before and after figures to hand. ## When a DPF clean is not the solution One thing is what treatment fixes — a filter choked with soot and ash. It does little for: - temperature or pressure sensors reporting a restriction that is not there - an EGR valve stuck open - the AdBlue system failing - injectors or glow plugs that stop a regeneration running at all - turbo problems, with oil reaching the filter Finding that out is the first diagnostic's job. Proving to be one of them means finding out it before work starts, not after settling up anything. Two more worth bearing in mind. Leaving the filter cut out is not a solution — a vehicle without a serviceable DPF cannot pass its MOT and driving it is illegal. And cleaning is sometimes looked up as DPF renewal: nothing is swapped, your existing filter is treated in place and returned into use. ## Costs for DPF cleaning in Citadel The treatment opens from £299. A call-out charge is added to every visit, and takes in the call-out itself, the booking, the scan and the advice that comes with it. Not one flat rate would be honest, so the price is settled over the phone once we are told the vehicle and what the filter is likely to need. The place you are counts as much as what you own: Citadel itself, Inverness close by, or farther out within the IV postcode area. Where the diagnostic says a clean will not do it, you are not charged for cleaning. The call-out charge even so holds, because the visit, the check and the advice have happened. Aftercare is covered by a 30-day warranty: should the light return within it, an engineer returns to Citadel. ## The vehicles we clean and the patch we take in near Citadel The filter is cleaned in place on all of them: cars, vans of any size and light commercials, heavy goods vehicles, construction and plant machinery, farm vehicles. Nothing is carried anywhere. The same run that has technicians on Shore Street most weeks picks up Citadel, Inverness, South Kessock and the spots beyond North Kessock. Ring anyway from even further out through Highland. Coverage extends UK-wide, and the slot you get hangs on the schedule rather than how far away you are. ## A note on Citadel Citadel is a coastal suburban area in the Highland county of Scotland, situated very close to the city of Inverness. Citadel sits at a low elevation of around 5 metres, looking out over the Moray Firth. Citadel is characterised by its predominantly flat-type housing and is located near other suburban areas such as Glebe and Merkinch. ## Questions Citadel drivers ask about DPF cleaning Does a long run shift it? Early enough, and with the car out of limp mode, yes — sometimes. That means motorway speed for a sustained spell, rather than a short trip to Morrisons. Does the visit last long? Plan on typically around 2 hours — severely blocked filters sometimes need a second pass, which extends it. How much does it cost around Citadel? Cleaning begins from £299, and the call-out charge on top pays for the visit, the diagnostic and the advice. The vehicle and your address both change the number, so we quote on the phone. Do I have to be there? The vehicle wants a place for two hours or so. You do not need to be in it. Preferring to be there is fine: the regeneration then runs out on the open road, monitored. Coming to Citadel — how soon? It is often same-day or next-day, depending on what is currently in the schedule. Phone 0303 330 1830 and we will say to you what is available across the IV area.
