Your car is not taken away and the filter doesn't come off. A fitter arrives at your place across Old Toll, cleans the diesel particulate filter fitted to the vehicle and performs a DPF regeneration. The visit lasts typically around 2 hours, the clean starts from £299, and the number is settled on the phone before anyone leaves. Most people find us with the light already on, and the motor low on power. That is exactly what this page is aimed at. ## What to try when the DPF light comes on First thing: it is not automatically the DPF. A check happens before the work, because that same dash light has several candidate faults behind it. It tells what you get with the motor between now and the visit. - Amber light, car yet driving fine — a long constant run can even now sort it by itself. Costs nothing, and worth trying before you call anything. - That window has gone once the vehicle has dropped into limp mode. A drive will not do it now. - Stop booking long drives and get it looked at if the car stinks of diesel or there is black smoke when you press on. ## Signs the vehicle has been showing you By the time the light appears, things have generally been going wrong for a while. It is last news: - less power, above all pulling uphill - an engine whose revs will not pull as they should - the fuel use is poorer - without a word, the stop/start gives up - smoke under hard acceleration, or a diesel smell in the car Any one of those, taken by itself, is not conclusive. It is a fair guess the filter is blocked once the light is there too. ## Why diesel particulate filters clog near Old Toll The day-to-day driving that comes with a coastal area like Old Toll is the least kind sort for a DPF. The school run to the local primary school, A77 at a standstill at half past eight, ten minutes to Spar, the run to Ayr — nothing of it goes on long enough or runs hot enough for the filter to complete a regeneration. The soot collects rather than burning away. Neither is a long way from Old Toll: under 15 miles to the M77, under 50 miles to Glasgow. Neither is on the way to anywhere most weeks, though, so the journey that would scour a filter never comes. ## Limp mode, and when DPF regeneration stops working Limp mode is the motor looking after itself. The entire problem is that a long drive works by setting off a regeneration, and under limp mode the revs will not climb and power is capped. So the standard advice to run it up the motorway is sensible advice, right until it stops being. The far side of that line — limp mode — driving will not manage it, and the filter wants treatment. ## Call-out DPF cleaning where the motor stands in Old Toll The filter does not budge. That is the part most drivers do not see coming: the job is done with the DPF yet fixed to the motor, on your drive, in a work car park, wherever the motor can sit for a couple of hours. A check goes first — live data off the ECU, soot load by proportion and by mass, and a check of the sensors, glow plugs and associated hardware, so other faults are ruled out before anything is cleaned. Then the cleaning. A solution is fed in through the entry point on that motor and expands inside the filter, lifting the soot and ash a regeneration alone will never move. Heavily loaded filters sometimes need a second pass. What the clean has loosened is then driven off by a regeneration. Either it is done as a monitored drive out of Old Toll, with you present, or it goes where the motor sits and the running data is read after. A second scan confirms the change, clears the warning light and logs anything still open. Both read-outs are emailed, so you have the before and after figures to hand. ## Where a clean is not the fix A clean cures one thing: a filter blocked with soot and ash. It does no good for: - a temperature or pressure sensor showing a block that is not there - an EGR valve jammed open - a failure in the AdBlue system - glow plugs or injectors stopping the regeneration starting whatsoever - oil working through the filter from a worn turbo The first scan is there for exactly that. When it turns out to be one of those, you are told before any work gets going rather than after you have settled up a penny. DPF renewal is what people look up, but no part is swapped: the filter you already own is cleaned where it sits and returned to use. Nor is having it gutted a remedy, since the MOT then fails and driving becomes an offence. Two more things worth bearing in mind. ## DPF cleaning prices across Old Toll Cleaning opens from £299, with the call-out charge on top of that for every visit — it covers the call-out, the booking, the checks and the advice. The number is fixed by the phone, once we know the vehicle and what the filter is going to need. No flat rate could be straight. Two things move it: what you drive, and where you are — Old Toll itself, across at Castlehill, or farther out within the KA postcode area. You are not asked to pay for a clean that the scan says will not do it. What even so holds is the call-out charge, since the visit took place, the scan was run and the advice was passed on. A 30-day warranty includes aftercare on the job, and that includes an engineer coming back out to Old Toll if the light comes back inside the window. ## The vehicles we clean and the patch we cover around Old Toll A single call-out service covers private cars, vans of any size and light commercials, heavy goods vehicles, construction and plant machinery and farm vehicles, and on every one the filter is cleaned where it sits rather than taken anywhere. Nearly every week there is by then someone on A77, so Old Toll seldom means a detour, and Castlehill, Forehill and the villages past Ayr follow. Farther out across South Ayrshire is nonetheless worth a call — coverage reaches UK-wide, and it is the diary rather than the distance that decides between this day and the next. ## About Old Toll Old Toll is a small coastal locality in South Ayrshire, situated near the towns of Holmston and Masonhill.

If you get it in time, and the motor is not in limp mode, sometimes. It wants a sustained run at motorway speed, not ten minutes to Spar and back. How long does the visit last? Reckon on typically around 2 hours, with a second clean lengthening that where the filter is heavily loaded. How much does it come to in Old Toll? It starts from £299, plus the call-out charge covering the visit, the scan and the advice. Settling it is done by phone, since what you run and where you live both move the figure. Must I be around in person? A spot for the car to stand, for a couple of hours, is all that is wanted. Not you. The regeneration can be carried out as a supervised drive if you would prefer to come along. Can someone get to Old Toll soon? Depending on the calendar, often same-day or next-day is usual. Ring 0303 330 1830 and you will know what is open across the KA area. Is the filter lifted off the motor? Not on the on-site service — it is done where it sits. And neither does getting a filter off nor bolting one back on is work we do. Suppose the light comes back? The 30-day warranty takes in aftercare, including an engineer heading back to Old Toll. ## Book a DPF clean in Old Toll Phone 0303 330 1830 and tell us what the car is doing — light, limp mode, smoke, whatever it is.
