Your motor will not be taken off and the filter will not come off. A technician comes at your place over in Constantine Bay, cleans the diesel particulate filter on the car and performs a DPF regeneration. Nobody leaves until the figure is fixed over the phone. The visit lasts typically around 2 hours and the clean opens from £299. If the light is already on and the motor is low on power, this page is yours. That is how most people get to us. ## DPF light on? What comes next The DPF is not always what is wrong, and that comes first. A number of faults put the identical light on the very same dashboard, which is why a visit starts with a scan rather than with a clean. How the motor is handled in the meantime counts too. - Motor yet driving fine on an amber light — attempt a long steady run first. It costs nothing and regularly sorts the filter without help. - That window has gone once the motor has fallen into limp mode. Driving will not do it now. - Stop booking long drives and get it seen to if the cabin stinks of diesel or there is black smoke when you pull away. ## Before the light, what the motor was telling you By the time the light shows, things have normally been slipping for some time. It is late news: - less power, above all going uphill - you find the revs fall short of where they always went - economy that is worse than it used to be - the stop/start silently giving up - a diesel smell in the car, or smoke under the throttle That is not proof on its own. Next to the light, it is a fair guess the filter is loaded. ## The cause diesel particulate filters clog around Constantine Bay For a DPF, the poorest motoring is the type you meet in a coastal village such as Constantine Bay. The school run to St Merryn School, The Towans at a crawl at half past eight, a few minutes to Tesco, the run to Newquay — not one bit of it lasts long enough or is hot enough for the filter to finish a regeneration. Soot that should burn off banks up instead. The M5 sits over 50 miles from Constantine Bay, Truro under 25 miles out, and unless something takes you out that way often, whole weeks pass without the sustained run that scours a unit. Geography does not assist. ## DPF regeneration, and the moment limp mode ends it It is self-preservation: that is all limp mode means. With output held down and the revs pinned, the regeneration the filter requires cannot happen at all. That matters, because setting off one is precisely what a long run does. The common advice — get it up the motorway — is sound, until it is not. The filter requires cleaning rather than road work once the motor has gone into limp mode. ## Where the vehicle stands is where the DPF is done across Constantine Bay Nothing comes off the vehicle. That catches out people. The DPF stays fitted where it is and the work goes on around it, on a forecourt, in a works car park, any place it can sit for a few hours. The ECU is taken first, giving soot load by percent and by mass, along with a check of sensors, glow plugs and associated components, so nothing is cleaned while another fault is still open. Soot and ash that a regeneration alone will never move are lifted second, by a solution fed through the access port on that motor, which opens out inside the filter. Badly loaded filters sometimes require a second pass. Next, a regeneration drives off everything the clean loosened. Ride along with the car and it turns into a monitored drive out of Constantine Bay. Park it and the regeneration runs statically, with real-time data verified once it is done. A second diagnostic proves the change, puts out the warning light and lists anything still open. Both read-outs are sent over, so you have the before and after figures on record. ## The failures a DPF clean cannot answer A clean fixes one thing: a filter choked with soot and ash. It does nothing for: - a pressure or temperature sensor showing a restriction that is not there - the EGR valve stuck open - a problem in the AdBlue system - failed glow plugs or injectors, so never a regeneration ever starts - a turbo pushing oil through the filter The first check is there for exactly that. If one of those proves the fault, you hear about it in advance rather than once the money has gone for good. Gutting the filter out is not a fix: without a working DPF a vehicle fails its MOT, and driving it is illegal. DPF renewal is the phrase people search for, though nothing is exchanged — your original filter is cleaned in place and put back into use. Two more worth knowing. ## DPF cleaning costs in Constantine Bay Cleaning begins from £299, with the call-out charge on top of that for every visit — it pays for the call-out, the booking, the diagnostics and the advice. Naming a flat rate would not be straight. We settle it by phone, once the motor and its probable needs are established. The place you are counts as much as what you run: Constantine Bay itself, Harlyn next door, or further out within the PL postcode area. Cleaning that will not work is not cleaning you pay for, and the check is what says so. The call-out charge even so holds, because the visit, the scan and the advice have happened. If the light comes back inside that period, an engineer heads back out to Constantine Bay — the clean comes with a 30-day warranty covering aftercare. ## Vehicles we clean, and where we travel round Constantine Bay Whatever it is — car, light van, light commercial, lorry, plant, construction machinery, farm vehicle — the very same mobile service stands, and the filter never leaves it. Our engineers are along The Towans week in week out, so Constantine Bay is hardly ever a special trip, and the same run takes in Harlyn, Shop and the places out past Treyarnon. Coverage runs UK-wide, so even further out across Cornwall is still worth a call, and what decides between today and tomorrow is the calendar rather than the distance. ## The ground around Constantine Bay Constantine Bay is a small coastal village in Cornwall, situated near the popular beaches of Treyarnon and Towan.

If you spot it early enough, and the car is not in limp mode, sometimes. It wants a long run at motorway speed, not fifteen minutes flat to Tesco and back. About how long does it take? Count on typically around 2 hours, with a second clean extending that where the filter is severely blocked. In Constantine Bay, what does it run to? Beginning from £299, with a charge for the call-out that pays for the check and advice on what to do next. Both the vehicle and where you are change it, which is why settling it happens by phone. Must I be there in person? Nobody expects you to stand with it — the vehicle simply requires space to stand for a couple of hours. Wanting to be there is no problem: the regeneration then goes out on the open road, monitored. When can someone get to Constantine Bay? Depending on the diary, often same-day or next-day is normal. Phone 0303 330 1830 and we will tell you what is free across the PL area. Does the filter come off the vehicle? It is done where it stands, on the mobile service. Lifting a filter off or bolting one back on amount to anything something we do either way. Suppose the light returns? An engineer comes back out to Constantine Bay — the 30-day warranty covers aftercare. ## Organise DPF cleaning around Constantine Bay However it is doing — light, limp mode, smoke — say so when you phone 0303 330 1830.
