Childerley, Cambridgeshire: Mobile DPF Cleaning
The motor sits where it is — mobile DPF cleaning comes to it. No body shop, no filter leaving. A technician comes to your place across Childerley, clears the diesel particulate filter where it is, runs a DPF regeneration, and you end up with the filter you started with.
The visit lasts typically around 2 hours, the clean starts from £299, and the figure is fixed over the phone before anyone travels.
If the light is showing and the motor is low on power, this page is the right one. That is how most people end up here.
Your DPF light is showing — what then?
The filter is not automatically what is wrong, and that leads. That light can arise from several faults, not merely one, so the visit begins with a scan and not with a clean.
How the motor is run in the meantime matters too.
- Amber light, car still driving fine — a long even run can still clear it by itself. Costs nothing, and worth attempting before you book anything.
- A drive will not touch it now — limp mode means that window has by then closed.
- Stop arranging long drives and get it checked if the car stinks of diesel or there is black smoke when you press on.
What the motor has been warning you
By the time the light shows, things have generally been slipping for weeks. It is late news:
- power falling off, particularly pulling uphill
- an engine whose revs will not climb as before
- fuel economy turning worse
- a stop/start that has silently given up
- diesel in the cabin, or smoke on the way up through the box
That is not conclusive on its own. Next to the light beside them, the filter is a fair guess.
The reason diesel particulate filters block near Childerley
For a DPF, the poorest driving is the type you get around a rural hamlet such as Childerley. The school run to Dry Drayton CofE (C) Primary School, High Barns at a crawl at half past eight, a few minutes to Tesco Extra, the dash to Cambridge — nothing of it goes on long enough or runs hot enough for the filter to finish a regeneration. The soot collects rather than burning off.
The M11 stands under 5 miles from Childerley, Cambridge under 10 miles off, and unless something pulls you out that way regularly, full weeks slip past without the long steady run that clears a unit. Geography does not oblige.
Limp mode, and when DPF regeneration stops
What limp mode comes down to is the vehicle looking after itself. The entire difficulty is that a proper drive works by setting off a regeneration, and in limp mode the revs will not pull and power is limited.
The standard advice — get it up the motorway — is sensible, until it is not. In limp mode you are the far side of that stage: treatment is what will help, not more road work.
The motor stays where it is for mobile DPF cleaning in Childerley
Most drivers do not expect this part: the filter remains. The job is done with the DPF still fitted to the car — on your drive, in a work car park, any place the motor can stand for a few hours.
Nothing is started until other faults are eliminated. That means a scan first: live data off the ECU, soot load by percent and by actual weight, and a check of the sensor feeds, glow plugs and associated components.
A solution next is injected through the access port on that vehicle, opening out inside the filter to lift soot and ash a regeneration by itself will never budge. Where the filter is badly blocked, expect a second pass.
A regeneration is next, burning off what the clean has loosened. Either it is done as a monitored drive out of Childerley, with you present, or it goes where the car sits and the live data is read after.
Then a second check, verifying the change, putting out the warning light and listing anything still showing. Both sets of figures are emailed, so the before and after figures are kept.
What a DPF clean will not fix
A filter clogged with soot and ash is the one thing cleaning fixes. It will not touch:
- pressure sensors showing a blockage that is not there
- EGR valves that hang open
- AdBlue system faults
- worn glow plugs or injectors, so no regeneration ever runs
- the turbo putting oil into the filter
That is what the first check is for. If it proves to be one of those, you are let know before any work starts rather than after you have paid for it.
Lastly, two things. A vehicle with the filter cut out fails its MOT, and driving it is against the law, so that is no remedy. What gets looked up as DPF renewal replaces nothing: your filter is treated in place and goes back into work.
Figures for DPF cleaning around Childerley
Each visit attracts a call-out charge — getting to you, setting up the booking, running the scan and giving the advice. The clean itself starts from £299.
Quoting a flat rate would not be straight. We fix it by phone, once the car and its expected needs are known. The place you are matters as much as what you own: Childerley itself, Dry Drayton next door, or farther out in the CB postcode area.
Where the diagnostic says cleaning will not do it, you are not asked to pay for a clean. The call-out charge still applies, because the visit, the check and the advice have been done.
Aftercare is included by a 30-day warranty: should the light come back within it, an engineer comes back to Childerley.
Yes all good at the moment, Dpf cleaned and warning lights off. Engineer was friendly and helpful. Car running well. Thank you for a good service.
Great service, Dave the the guy he fixed my car was very friendly and helpful. D P F fixer highly recommended company, thank you.
Liam came to the House next day, incredibly helpful bloke, talked me through everything and how to stop the DPF blocking up in the future. Well worth the money, saved me loads of problems, highly recommend these guys.
Vehicles we clean, and where we get to around Childerley
The one on-site service covers cars, vans and light commercials, HGVs and lorries, plant and construction machinery and agricultural vehicles, and on every one the filter is cleaned where it sits rather than moved anywhere.
Most weeks there is by then someone on High Barns, so Childerley hardly ever means a special trip, and Dry Drayton, Knapwell and the spots past Childerley Gate follow. Further out through Cambridgeshire is even so worth phoning about — coverage runs UK-wide, and it is the diary rather than the distance that decides between today and tomorrow.

Questions Childerley drivers ask about DPF cleaning
- Can I merely take it for a long drive?
- Early enough, and with the vehicle out of limp mode, yes — sometimes. It needs a sustained run at motorway speed, not fifteen minutes flat to Tesco Extra and back.
- The visit takes how long?
- It is typically around 2 hours. A heavily blocked filter can take a second clean, which lengthens that.
- What does it run to around Childerley?
- A clean begins from £299, and the call-out charge on top takes in the visit, the check and the advice. We settle it on the phone, because the vehicle and your address both move the figure.
- Have I have to be there?
- No. The vehicle wants space to stand for a couple of hours; nobody expects you to stand with it. Preferring to be there is no problem: the regeneration then goes out on the open road, monitored.
- How soon can someone travel to Childerley?
- It is often same-day or next-day, depending on what is now in the schedule. Ring 0303 330 1830 what is available across the CB area.
- Does the filter come off the car?
- Cleaned where it is, on this service, so no. We never get filters off or bolt them back on, in either direction.
- The light returns — then what?
- The 30-day warranty includes aftercare, including an engineer heading back to Childerley.
