Semington, Wiltshire: Mobile DPF Cleaning
Sorting the DPF takes place at the car, not at a body shop. The engineer arrives at your place in Semington and sets up. The diesel particulate filter is cleared on the vehicle, a DPF regeneration comes next, and you end up with the filter you arrived with.
The visit takes typically around 2 hours, the clean begins from £299, and the number is fixed over the phone before anyone travels.
Most people find us with the light on already, and the motor low on power. That is the situation this page is written for.
What to try when the DPF light comes on
It may not be the DPF at all. That is the opening thing. Cleaning is not where a visit opens. A scan is — a number of faults register as the same warning.
Second thing: how you run it between now and then makes a difference.
- Worth a go before you call anything: amber light, car driving normally, just one constant run, no outlay.
- That window has closed once the vehicle has dropped into limp mode. A drive will not do it now.
- Stop arranging long drives and get it checked if the interior smells of diesel or there is black smoke when you pull away.
Before the light, what the motor was showing you
Symptoms have usually been growing for a while before the light so much as arrives. Late news, in other words:
- power falling off, especially pulling uphill
- an engine whose revs will not climb like they did
- economy that is worse than it was
- the stop/start quietly giving up
- diesel in the cabin, or smoke on the way up through the gears
That is not evidence on its own. With the light with them, the filter is a fair bet.
The cause diesel particulate filters clog near Semington
The driving that comes with a village like Semington is the least kind kind for a DPF. A regeneration needs long enough and heat, and gets none: not on the school run to St George's Church of England Primary School, Semington, not on Highfield Close at half past eight, not on a few minutes to Sainsbury's, and not on the run to Melksham. What should burn away stays behind.
Neither is a long way from Semington: under 15 miles to the M4, under 10 miles to Bath. Neither is on the way to anything most weeks, though, so the run that would clear a filter never happens.
Limp mode, and when DPF regeneration stops working
The vehicle is protecting itself, which is what limp mode amounts to. The whole problem is that a proper drive works by starting a regeneration, and once in limp mode the revs will not pull and power is limited.
The common advice — get it up the motorway — is good, until it is not. Once the vehicle is in limp mode you are beyond that point, and the filter wants treatment rather than driving.
DPF cleaning at the vehicle across Semington
On your front, in a work car park, wherever the motor can wait for a couple of hours: the job takes place with the filter still fitted on, which is the part most owners do not anticipate.
A diagnostic comes first — running data off the ECU, soot load by percent and by weight, and a look over of the sensors, glow plugs and related hardware, so other faults are ruled out before any of it is touched.
Then the clean. A cleaning solution is injected through the access port on that vehicle and spreads inside the filter, lifting the soot and ash a regeneration alone will never move. Severely clogged filters sometimes require a second pass.
What the clean has freed is then driven off by a regeneration. That is a monitored drive out of Semington if you are there, or a static regeneration where the motor sits, with the live data checked after.
Both reports are sent by email, so the figures from either end are recorded. The second scan is what proves the change, resets the light and notes whatever is still outstanding.
What a DPF clean will not fix
A filter blocked with soot and ash is the one thing treatment answers. It will not reach:
- the wrong reading from a temperature or pressure sensor
- an EGR valve held open
- a fault in the AdBlue system
- worn glow plugs or injectors, so no regeneration ever completes
- oil coming through the filter from a faulty turbo
Which is why the diagnostic happens first. You are told before any work starts, not after you have handed over, should it turns out to be one of those.
Lastly, two things. A vehicle with the filter gutted fails its MOT, and driving it is against the law, so that is no solution. What gets typed in as DPF renewal swaps nothing: your filter is treated in place and goes back into use.
DPF cleaning costs in Semington
A clean opens from £299, with the call-out charge on top of that for every visit — it takes in the call-out, the booking, the checks and the advice.
Once we are told what you run, and about what the filter will need, the number gets agreed by phone. A single price for every job would not be truthful. The place you are matters as much as what you run: Semington itself, Outmarsh nearby, or farther out within the BA postcode area.
Treatment that will not do it is not treatment you pay for, and the diagnostic is what says so. The call-out charge nonetheless stands, because the visit, the check and the advice have happened.
If the light comes back inside that window, an engineer heads back out to Semington — the job includes a 30-day warranty including aftercare.
Perfect service. I would recommend DPF Fixer to anyone. Turned up on time. Did a good job and a sensible price.
Very clear on all aspects very nice guy who come to clean my dpf good price as they come to your home thanks guys.
Jamie was a star gave me an ETA and text well before appointment time. Arrived and got straight to work. Listed a few faults and explained clearly once I have these fixes they will come back and do the regen for free. Highly recommended.
Where we travel round Semington, and what we clean
Cars and estates, vans and light commercials, HGVs, plant and construction machinery, farm vehicles — the one on-site service across all of them, and on all of them the filter is done on the vehicle rather than moved anywhere.
Semington is rarely a special trip: engineers are along Highfield Close most weeks, and the same run covers Outmarsh, Berryfield and the spots out past Great Hinton. Further out through Wiltshire is still worth phoning about — coverage reaches UK-wide, and it is the schedule rather than the distance that settles between this day and the next.

Frequent questions on DPF cleaning around Semington
- Will a long drive clear it?
- Sometimes, if you catch it early enough and the motor has not slipped into limp mode. Five minutes to Sainsbury's and back will not do it; motorway speed, held for a stretch, will.
- How long does the visit run?
- Count on typically around 2 hours, with a second clean adding to that where the filter is severely blocked.
- The cost around Semington — what is it?
- It opens from £299, plus the call-out charge paying for the visit, the scan and the advice. We settle it on the phone, because the vehicle and your address both move the number.
- Have I need to be there?
- No. The motor needs a spot to sit for a couple of hours; you do not need to stand with it. Wanting to be there is fine: the regeneration then is done out on the open road, monitored.
- Travelling to Semington — how soon?
- Depending on the diary, often same-day or next-day is normal. Phone 0303 330 1830 and you will learn what is open across the BA area.
- The filter — does it come off the car?
- Not on the on-site service — it is cleaned where it is. Lifting a filter off or bolting one back on amount to anything a job we do either way.
- What if the light reappears?
- The 30-day warranty includes aftercare, including an engineer coming back to Semington.
