Little Marsh, Wiltshire: Mobile DPF Cleaning
Treating the DPF is done at the vehicle, not at a garage. Your car is not taken anywhere and the filter does not budge. A technician comes at your door in Little Marsh, cleans the diesel particulate filter fitted to the motor and runs a DPF regeneration.
Reckon on the visit running typically around 2 hours. The clean starts from £299, agreed on the phone before anyone travels.
Most owners find us with the light showing, and the vehicle low on power. That is exactly what this page is aimed at.
DPF light on? What to do
First thing: it is not necessarily the unit. Several faults put the same light on the very same dashboard, which is why a visit opens with a check rather than with a clean.
How the motor is run in the meantime makes a difference too.
- Worth a shot before you call anything: amber light, car driving as normal, just one constant run, no outlay.
- That window has shut once the motor has fallen into limp mode. Motoring will not do it now.
- Diesel smell in the cabin, or black smoke under hard acceleration — stop planning long drives and get it seen to.
Signs the motor has been sending you
By the time the light appears, things have usually been deteriorating for weeks. It is last news:
- power tailing off, especially pulling uphill
- an engine whose revs will not pull like they did
- fuel consumption turning worse
- silently, the stop/start gives up
- smoke under hard acceleration, or a diesel smell in the car
Any one of those, taken alone, is not conclusive. The light beside them suggests a full filter.
What blocks diesel particulate filters around Little Marsh
The motoring that comes with a rural hamlet like Little Marsh is the least kind sort for a DPF. Look at a typical week: St George's Church of England Primary School, Semington and back, A350 at a halt before the hour, a quick trip to Lidl, a hop to Melksham. Not much there runs long enough or is hot enough to finish a regeneration. The soot that should burn away builds up instead.
Where you sit does not help either. The M4 is under 15 miles from Little Marsh and Bath is under 10 miles away, so unless something takes you out that way often, weeks slip past without the long steady run that could empty the filter alone.
The stage a DPF regeneration can no longer complete
Limp mode is the car looking after itself. A long drive works by triggering a regeneration, and that is just what limp mode blocks: power limited, revs kept low, no regeneration on offer.
Sound advice, that motorway run — up until the moment it is not. Once the vehicle is in limp mode you are past that point, and the filter requires cleaning rather than more driving.
On-site DPF cleaning where the car stands across Little Marsh
The filter does not leave it. That is the detail most drivers do not anticipate: the job is done with the DPF still bolted to the car, on your front, in a work car park, anywhere the vehicle can sit for a while.
Nothing is started until other faults are eliminated. That involves a scan first: real-time data off the ECU, soot load by proportion and by weight, and a review of the sensor feeds, glow plugs and connected parts.
Then the cleaning. A cleaning fluid is fed in through the access port on that vehicle and expands inside the filter, freeing the soot and ash a regeneration on its own will never move. Sometimes a filter is clogged enough to take doing twice.
Next, a regeneration drives off everything the clean loosened. That is a monitored drive out of Little Marsh if you are there, or a static regeneration where the car sits, with the real-time data checked once done.
A second check verifies the change, puts out the warning light and logs anything still showing. Both read-outs are sent over, so you end up with the before and after figures recorded.
Where cleaning is not the fix
A clean answers one thing: a filter clogged with soot and ash. It does no good for:
- a temperature or pressure sensor showing a blockage that is not there
- EGR valves that hang open
- a problem in the AdBlue system
- a regeneration that hardly ever runs, because of glow plugs or injectors
- turbo problems, with oil reaching the filter
Which is why the check happens first. If one of those is the fault, you learn of it at the outset rather than once the money has gone already.
Hollowing the filter out is not a solution: without a functioning DPF a vehicle will fail its MOT, and driving it is illegal. DPF renewal is the wording people type in, though nothing is swapped — your own filter is cleaned in place and returned into use. Two more worth bearing in mind.
What DPF cleaning costs across Little Marsh
Each visit takes a call-out charge — coming out to you, setting up the booking, doing the scan and passing on the advice. The clean itself begins from £299.
No single flat rate would be straight, so the number is agreed over the phone once we have the vehicle and what the filter is likely to need. The place you are tells as much as what you drive: Little Marsh itself, Cold Harbour next door, or otherwise out within the BA postcode area.
You are not asked to pay for treatment that the check says will not do it. You even so pay that charge: someone came out, did the scan and passed on you the advice.
A 30-day warranty covers aftercare on the clean, and that includes an engineer heading back out to Little Marsh if the light returns inside the period.
Great service. No garages would touch the issue so to find this company that comes to your house was brilliant. Effective communication and booked in quickly which I appreciated. The job was completed before I could offer them a cuppa! I would recommend this company.
Daniel was an outstanding mechanic he went out of his way to help me fix my car would very highly recommend thank you!
DPF Fixer responded quickly to my enquiry and arranged same day visit. The engineer, Dave, advised his time of arrival and promptly carried out the successful clean and regeneration on my LR Discovery Sport. Very pleased with the service and advice from DPF Fixer. Thank you.
What we clean, and how far we reach round Little Marsh
Whatever it is — private car, light van, light commercial, heavy goods vehicle, plant, construction machinery, agricultural vehicle — the same on-site service holds, and the filter never departs it.
Most weeks there is by then someone on A350, so Little Marsh rarely means a journey of its own, and Cold Harbour, Great Hinton and the villages past Semington come with it. Farther out around Wiltshire is even so worth a call — coverage reaches UK-wide, and it is the diary rather than the distance that decides between today and tomorrow.

Usual questions on DPF cleaning in Little Marsh
- Will a long drive shift it?
- If you spot it early enough, and the motor is not in limp mode, sometimes. A sustained run at motorway speed is what it wants — not fifteen minutes flat to Lidl and back.
- How long does the visit take?
- Bank on typically around 2 hours, with a second clean extending that where the filter is badly clogged.
- Price in Little Marsh — what is it?
- It starts from £299, plus the call-out charge taking in the visit, the scan and the advice. We quote on the phone, because the vehicle and your address both move the price.
- Must I be around in person?
- You do not need to stand with it — the car just requires a spot to sit for a couple of hours. The regeneration can be run as a supervised drive if you would rather come along.
- How soon can someone get to Little Marsh?
- Depending on the schedule, often same-day or next-day is usual. One ring to 0303 330 1830 and you will hear what the BA area has open.
- Does the filter leave the vehicle?
- Not on the on-site service — it is treated where it sits. We will not lift filters off or put them back on, whichever way.
- What if the light returns?
- Included by the 30-day warranty: aftercare, and an engineer coming back to Little Marsh.
