Pewsham, Wiltshire: Mobile DPF Cleaning
With on-site DPF cleaning, we come to the vehicle. An engineer turns up at your place over in Pewsham, treats the diesel particulate filter while it is still on the motor, runs a DPF regeneration, and you hold on to the filter you came with.
Nobody leaves until the figure is fixed over the phone. The visit lasts typically around 2 hours and the clean begins from £299.
Written for the position most owners are in: the light on already, the vehicle short for power, and the job still to fix.
Your DPF light is on — what next?
The unit is not automatically what is wrong, and that goes first. A scan comes before all work, because that same dashboard light has a number of likely faults behind it.
How the car is driven in the meantime counts too.
- A long constant run may even now be enough, provided the light is amber and the car goes fine. Costs zero, so try that before calling.
- Once the vehicle is in limp mode, a long run will not reach it. The window has shut.
- Get it checked rather than running it — diesel in the interior, or smoke on hard acceleration, has gone well past the long-run stage.
What the motor has been showing you
The light is late news. By the time it shows, the symptoms have normally been growing for some time:
- less power, particularly pulling uphill
- you notice the revs stop short of where they always went
- fuel use that is worse than it used to be
- stop/start quietly packing in
- diesel in the interior, or smoke on the way up through the gearbox
Any one of those, taken alone, is not proof. Next to the light with them, the filter is a fair assumption.
Why diesel particulate filters choke round Pewsham
For a DPF, the worst motoring is the kind you meet around a small village such as Pewsham. The school run to Kings Lodge Primary School, Pewsham Way at a crawl at half eight, ten minutes to Lidl, the dash to Chippenham — none of it runs long enough or runs hot enough for the filter to see through a regeneration. Instead of burning away, the unburnt soot builds up.
Neither is far from Pewsham: under 5 miles to the M4, under 15 miles to Bath. Neither is on the way to anywhere most weeks, though, so the run that would empty a filter never comes.
The point a DPF regeneration can no longer complete
What limp mode comes down to is the car looking after itself. Pulling power is limited, the revs will not climb, and the regeneration the filter wants can no longer complete — which is the real catch, because a sustained drive works by triggering that regeneration.
Getting it up the motorway is the standard advice, and it stands right up to a point. Once the motor is in limp mode you are past that point, and the filter wants cleaning rather than road work.
Where the motor stands is where the DPF is done in Pewsham
The filter does not come off. That is the detail most people do not anticipate: the job is done with the DPF yet fitted to the car, on your driveway, in a work car park, any place the motor can wait for a couple of hours.
Nothing is touched until other faults are cleared. That means a diagnostic first: live data off the ECU, soot load by percentage and by weight, and a look over of the sensor feeds, glow plugs and connected hardware.
A cleaning fluid after that goes in through the access port on that car, spreading inside the filter to lift soot and ash a regeneration by itself will never shift. A second pass is sometimes needed on heavily blocked filters.
A regeneration follows, burning off what the clean has freed. Either it is done as a monitored drive out of Pewsham, with you present, or it is done where the vehicle sits and the live data is read afterwards.
A second check verifies the change, clears the warning light and lists anything still showing. Both read-outs are emailed, so you keep the before and after figures to hand.
When a DPF clean is not the solution
A clean cures one thing: a filter blocked with soot and ash. It does nothing for:
- temperature or pressure sensors showing a block that is not there
- an EGR valve jammed open
- a fault in the AdBlue system
- a regeneration that hardly ever runs, because of glow plugs or injectors
- oil working through the filter from a failing turbo
Finding that out is the first check's purpose. Transpiring to be one of them means learning it before work starts, not after handing over a penny.
A couple more worth knowing. Leaving the filter gutted is not a solution — a vehicle without a serviceable DPF will fail its MOT and driving it is illegal. And cleaning is sometimes looked up as DPF renewal: nothing is exchanged, your own filter is cleared in place and returned into use.
What DPF cleaning comes to across Pewsham
The clean begins from £299. A call-out charge covers every visit, and pays for the call-out itself, the booking, the check and the advice that goes with it.
Publishing a flat rate would not be honest. We settle it by phone, once the vehicle and its likely needs are known. The motor changes it, and so does the address — Pewsham, Gladstone Parade, or somewhere further out in the SN postcode area.
Treatment that will not do it is not a clean you pay for, and the diagnostic is what says so. Because the visit, the scan and the advice have taken place, the call-out charge still applies.
If the light reappears inside that time, an engineer heads back out to Pewsham — the work carries a 30-day warranty including aftercare.
Great Job, Problem sorted fast, booked in arrived on time great guy worked on the van, also total value for money my van has its power back like it had when new in 2013. Thank you.
The team wee extremely helpful. Ashley the engineer was very professional and carried out a fantastic service on my car. Would definitely recommend DPF Fixer to anyone.
Had a clean. Didn't fix problem. Came back out. Still didn't fix the problem. Wast of time and £400.
What we clean, and how far we reach near Pewsham
Cars, vans and light commercials, HGVs and lorries, plant machinery, farm vehicles — a single call-out service across all of them, and on all of them the filter is done in place rather than carried anywhere.
Pewsham is rarely a special trip: engineers are along Pewsham Way most weeks, and the same run covers Gladstone Parade, Derry Hill and the villages out past Chippenham. Further out around Wiltshire is even so worth phoning about — coverage is UK-wide, and it is the calendar rather than the distance that decides between this day and the next.

Things Pewsham drivers ask about DPF cleaning
- Can I merely take it for a long drive?
- Early enough, and with the car out of limp mode, yes — sometimes. Fifteen minutes to Lidl and back will not manage it; motorway speed, kept for some time, will.
- The visit takes how long?
- Reckon on typically around 2 hours, with a second clean adding to that where the filter is severely loaded.
- How much does it run to in Pewsham?
- Beginning from £299, with a charge for coming out that covers the check and advice on what to do next. We quote on the phone, because the vehicle and your address both change the number.
- Have I got to be there?
- The car wants a place for two hours or so. You do not need to be in it. Preferring to be there is no problem: the regeneration then goes out on the road, monitored.
- When can someone get to Pewsham?
- It is often same-day or next-day, depending on what is already in the calendar. Ring 0303 330 1830 what is available across the SN area.
- Will the filter be lifted off?
- It is cleaned where it sits, on the mobile service. That work — a filter off, a filter back on — is not a job we do.
- What if the light comes back?
- Aftercare comes inside the 30-day warranty, and that includes an engineer returning to Pewsham.
