Your motor isn't taken off and the filter will not budge. An engineer comes at your door across Trelake, cleans the diesel particulate filter fitted to the car and performs a DPF regeneration. Budget for the visit lasting typically around 2 hours. The clean begins from £299, settled over the phone before anyone sets off. If the light is already on and the car is down on power, this page is yours. That is how most drivers get to us. ## The DPF light is on. What now? Not the unit, always. Main thing to get straight. A check happens before the work, because that same panel light has several likely faults behind it. How the vehicle is run in the meantime counts too. - Amber light, motor yet driving as normal — a long even run can yet clear it by itself. Costs zero, and worth a try before you call anything. - A drive will not reach it now — limp mode means that window has now gone. - Diesel smell in the interior, or black smoke under the throttle — stop arranging long drives and get it seen to. ## What the motor has been showing you By the time the light arrives, things have usually been deteriorating for a while. It is belated news: - less power, especially climbing uphill - revs that will not rise the way they used to - worse fuel economy - a stop/start that has silently bowed out - diesel in the interior, or smoke on the way up through the gears That is not evidence on its own. Next to the light, it is a fair assumption the filter is blocked. ## The cause diesel particulate filters choke around Trelake The day-to-day driving that comes with a coastal village like Trelake is the least kind kind for a DPF. The school run to Tintagel Primary School, Treknow Lane at a standstill at half eight, five minutes to Spar, the hop to the nearest station — nothing of it goes on long enough or gets hot enough for the filter to finish a regeneration. Instead of burning away, the soot banks up. The M5 lies over 50 miles from Trelake, Truro under 50 miles off, and unless something takes you out that way regularly, entire weeks go by without the sustained run that empties a DPF. Geography does not assist. ## Why limp mode prevents a DPF regeneration It is self-defence: that is all limp mode means. With output capped and the revs pinned, the regeneration the filter wants will not happen at all. That counts, because setting off one is just what a motorway run does. Sound advice, that motorway run — right up until the moment it is not. The filter requires treatment rather than more driving once the vehicle has gone into limp mode. ## The car stays in place for call-out DPF cleaning across Trelake Nothing leaves the motor. That catches out people. The DPF remains fitted where it is and the work happens around it, on a forecourt, in a works car park, any place it can stand for a couple of hours. The ECU is read first, giving soot load by percent and by mass, along with a review of sensor readings, glow plugs and associated hardware, so nothing is started while another fault is still possible. Soot and ash that a regeneration by itself will never shift are loosened second, by a cleaning solution put through the access point on that motor, which expands inside the filter. Sometimes a filter is blocked enough to need doing twice. What the clean has loosened is then burned off by a regeneration. Ride along with the car and it turns into a monitored drive out of Trelake. Park it and the regeneration is done on the spot, with live data read once it is done. A second diagnostic confirms the change, resets the warning light and notes anything still showing. Both sets of figures are emailed over, so you keep the before and after figures to hand. ## The failures a DPF clean cannot answer A filter blocked with soot and ash is the one thing cleaning answers. It will not touch: - pressure or temperature sensors flagging a block that is not there - the EGR valve stuck open - a failure in the AdBlue system - a regeneration that never runs, because of glow plugs or injectors - oil working through the filter from a faulty turbo That is what the first diagnostic is for. You are let know before all work gets going, not after you have paid, if it turns out to be one of those. Lastly, two things. A vehicle with the filter gutted will fail its MOT, and driving it is an offence, so that is no remedy. What gets searched for as DPF renewal replaces nothing: your existing filter is treated in place and goes back into work. ## The figure of DPF cleaning across Trelake The cleaning begins from £299. A call-out charge applies to every visit, and covers the call-out itself, the booking, the check and the advice that goes with it. Once we have what you own, and broadly what the filter will need, the figure gets settled on the phone. A single price for every job would not be honest. The vehicle moves it, and so does the address — Trelake, Trebarwith Strand, or a spot otherwise out in the PL postcode area. You are not asked to pay for treatment that the diagnostic says will not do it. You still pay that charge: someone turned up, ran the scan and offered you the advice. The job includes a 30-day warranty including aftercare, including an engineer coming back out to Trelake if the light returns inside that period. ## Where we get to round Trelake, and what we clean The filter is treated in place on all of them: cars, vans and light commercials, HGVs, construction and plant machinery, agricultural vehicles. Nothing is carried anywhere. Trelake is rarely a special trip: technicians are working Treknow Lane most weeks, and the same run picks up Trebarwith Strand, Trebarwith and the villages out past Treknow. Ring anyway from even further out across Cornwall. Coverage runs UK-wide, and the date you are given hangs on the calendar rather than how far away you are. ## About Trelake Trelake is a small village on the north Cornwall coast, situated near the popular beaches of Trebarwith Strand and Treknow. Trelake sits at an elevation of 102 metres, overlooking the surrounding countryside and coastline. Trelake is characterised by its predominantly detached housing stock, reflecting its rural setting and limited population of around 238 residents. ## Things Trelake drivers ask about DPF cleaning Does a long run shift it? Soon enough, and with the car out of limp mode, yes — sometimes. Fifteen minutes to Spar and back will not be enough; motorway speed, held for a stretch, will. About how long does it take? It is typically around 2 hours. A badly loaded filter can need a second clean, which adds to that. How much does it run to in Trelake? It starts from £299, plus the call-out charge taking in the visit, the check and the advice. Both the vehicle and where you are move it, which is why quoting is done by phone. Must I be around in person? Space for the vehicle to wait, for a couple of hours, is all that is required. Not you. Wanting to be there is fine: the regeneration then runs out on the road, monitored. When can someone get to Trelake? Depending on the schedule, often same-day or next-day is normal. Phone 0303 330 1830 what is open across the PL area. Will the filter be lifted off? It is done where it sits, on the call-out service. We never get filters off or bolt them back on, whichever way. Suppose the light comes back? Aftercare comes inside the 30-day warranty, and that includes an engineer heading back to Trelake. ## Arranging a DPF clean around Trelake Call 0303 330 1830 and tell us what the car is doing — the light, limp mode, smoke, whatever it is.
