A technician turns up at your door over in Woodcock Hill, clears the diesel particulate filter while it is still on the motor, runs a DPF regeneration, and you end up with the filter you started with. The visit runs typically around 2 hours, the clean starts from £299, and the figure is agreed over the phone before anyone travels. Most drivers find us with the light already on, and the motor short of power. That is the situation this page is meant for. ## What to try when the DPF light comes on The unit is not necessarily what is at fault, and that goes first. That light can follow several faults, not just one, so the visit opens with a scan and not with treatment. How the car is run in the meantime makes a difference too. - Amber light, motor even now driving fine — a long even run can even now clear it by itself. Costs nothing at all, and worth a try before you book anything. - Vehicle already gone into limp mode — that window has closed. A drive will not touch it now. - A diesel smell inside, or black smoke under hard acceleration, is the moment to stop planning long drives and ring. ## The vehicle has been showing you already Symptoms have generally been building for weeks before the light even arrives. Last news, in other words: - less power, particularly going uphill - you find the revs stop short of where they always went - the fuel consumption is worse - quietly, the stop/start bows out - the cabin stinking of diesel, or smoke when you accelerate Alone, none of that is conclusive. Alongside the light, it is a fair bet the filter is loaded. ## Clogged diesel particulate filters round Woodcock Hill, and the why Woodcock Hill is a rural hamlet, and the driving that belongs to one is the worst kind for a DPF. A regeneration wants time and heat, and sees neither: not on the school run to St Mary's Rickmansworth CofE Primary School, not on Woodcock Hill at half past eight, not on a few minutes to Tesco, and not on the run to Rickmansworth. The soot that should burn away builds up instead. Geography does not oblige either. The M25 is under 3 miles from Woodcock Hill and St Albans is under 15 miles away, so unless something carries you out that way routinely, whole weeks slip past without the sustained run that would scour the filter alone. ## Why limp mode prevents a DPF regeneration It is self-preservation: that is all limp mode is. The entire catch is that a sustained drive works by triggering a regeneration, and in limp mode the revs will not climb and power is capped. So the usual advice to run it up the motorway is sensible advice, until it stops being. In limp mode you are past that point: treatment is what will work, not more miles. ## Where the vehicle stands is where the DPF is done across Woodcock Hill On your front, in a work car park, any place the car can wait for a while: the job happens with the filter still bolted on, which is the bit most drivers do not see coming. The ECU is taken first, giving soot load by proportion and by actual weight, along with a review of sensor feeds, glow plugs and connected parts, so nothing is cleaned while another fault is still open. A cleaning fluid next goes in through the access point on that car, expanding inside the filter to free soot and ash a regeneration by itself will never shift. Where the filter is badly clogged, allow for a second pass. What the clean has lifted is then driven off by a regeneration. That is a monitored drive out of Woodcock Hill if you are along, or a static regeneration where the vehicle stands, with the real-time data checked afterwards. A second diagnostic verifies the change, clears the warning light and notes anything still showing. Both read-outs are emailed, so you have the before and after figures to hand. ## What a DPF clean will not fix One thing is what a clean fixes — a filter blocked with soot and ash. It does little for: - the wrong figure from a temperature or pressure sensor - EGR valves that hang open - a fault in the AdBlue system - glow plugs or injectors blocking the regeneration running whatsoever - turbo failure, with oil getting into the filter Which is why the check happens first. You are told before the work starts, not after you have settled up, should it turns out to be one of those. DPF renewal is what people search for, but no part is swapped: the filter you own is treated where it sits and returned to use. Nor is having it cut out a fix, since the MOT then fails and driving becomes an offence. Two more things worth knowing. ## What DPF cleaning costs around Woodcock Hill Every visit takes a call-out charge — coming out to you, setting up the booking, running the diagnostic and offering the advice. The clean itself starts from £299. The number is fixed over the phone, once we have the vehicle and what the filter is going to need. No flat rate could be honest. What you own and where you are both move it: Woodcock Hill itself, out at Harefield Grove, or farther out within the WD postcode area. You are not charged for a clean that the diagnostic says will not help. What nonetheless applies is the call-out charge, since the visit was made, the scan was run and the advice was passed on. A 30-day warranty covers aftercare on the work, and that includes an engineer coming back out to Woodcock Hill if the light reappears inside the period. ## The vehicles we clean and the patch we take in around Woodcock Hill Private cars, vans and light commercials, HGVs and lorries, plant machinery, agricultural vehicles — the one on-site service across all of them, and on all of them the filter is cleaned in place rather than taken anywhere. Nearly every week there is already someone on Woodcock Hill, so Woodcock Hill seldom means a journey of its own, and Harefield Grove, Harefield and the places past Hill End follow. Call anyway from even further out across Hertfordshire. Coverage reaches UK-wide, and the slot you get comes down to the calendar rather than how far away you are. ## About Woodcock Hill Woodcock Hill is a small hamlet in Hertfordshire, situated inland at an elevation of around 90 metres.
