Leonardston, Pembrokeshire: Mobile DPF Cleaning
With call-out DPF cleaning, we travel to the car. No workshop, no filter leaving. An engineer travels to your address in Leonardston, treats the diesel particulate filter in place, runs a DPF regeneration, and you keep the filter you arrived with.
Nobody travels until the price is agreed over the phone. The visit runs typically around 2 hours and the clean begins from £299.
The light is on already and the vehicle is low on power — that is how we generally come across people, and precisely what this page covers.
What to do when the DPF light shows
Not the filter, automatically. Main thing to note. Cleaning is not where a visit begins. A diagnostic is — plenty of faults show up as the same warning.
How the motor is driven in the meantime counts too.
- Worth a shot before you ring anything: amber light, vehicle driving fine, just one steady run, no outlay.
- Once the car is in limp mode, a long run will not shift it. The window has shut.
- Get it seen to rather than running it — diesel in the cabin, or smoke on acceleration, has gone past the long-run stage.
Before the light, what the car was warning you
By the time the light shows, things have generally been deteriorating for some time. It is belated news:
- tailing off on power, especially uphill
- you notice the revs stop short of where they once went
- consumption that is worse than before
- quietly, the stop/start packs in
- smoke under acceleration, or a diesel smell in there
None of that is proof on its own. The light alongside them indicates a blocked filter.
Why diesel particulate filters clog near Leonardston
Being a rural hamlet, Leonardston generates precisely the use a DPF handles the poorest. The school run to the local primary school, Leonardston Road at a standstill at the morning rush, ten minutes to Co-op Food, the hop to Pembroke Dock — nothing of it goes on long enough or is hot enough for the filter to finish a regeneration. Instead of clearing, the soot load collects.
Unless you have a regular reason to head out to the M4, under 50 miles from Leonardston, or over to St Davids under 25 miles away, entire weeks pass without a long steady drive. Geography is against you.
The point a DPF regeneration can no longer happen
It is self-defence: that is all limp mode means. With power capped and the revs kept low, the regeneration the filter requires cannot complete at all. That counts, because setting off one is just what a long run does.
Getting it up the motorway is the common advice, and it works as far as a limit. In limp mode you are past that point: treatment is what will do it, not more road work.
Mobile DPF cleaning where the car stands in Leonardston
Most drivers do not see coming this bit: the filter stays on. The job happens with the DPF yet bolted to the car — on your front, in a work car park, any place the vehicle can wait for a few hours.
A diagnostic happens first — real-time data off the ECU, soot load by percent and by mass, and a check of the sensor readings, glow plugs and connected parts, so other faults are cleared before any of it is cleaned.
A solution then goes in through the entry point on that car, opening out inside the filter to free soot and ash a regeneration by itself will never move. Where the filter is heavily loaded, expect 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 Leonardston, with you along, or it goes where the car sits and the running data is read after.
Finally the diagnostic runs again — the change proven, the light cleared, anything still showing written down. Both read-outs reach you by email, so the numbers are kept.
The problems a DPF clean cannot cure
Treatment cures one thing: a filter choked with soot and ash. It does little for:
- a pressure sensor showing a block that is not there
- a stuck-open EGR valve
- a failure in the AdBlue system
- faulty glow plugs or injectors, so no regeneration ever completes
- a turbo putting oil through the filter
Finding that out is the first check's purpose. Where it turns out to be one of those, you are let know 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 replaced: the filter you have is cleaned where it sits and sent back into service. Nor is having it gutted a fix, since the MOT then fails and driving becomes illegal. Two more things worth noting.
The cost for DPF cleaning in Leonardston
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.
Publishing a flat rate would not be honest. We settle it by phone, once the motor and its likely needs are known. Whereabouts you are tells as much as what you run: Leonardston itself, Glenowen nearby, or otherwise out within the SA postcode area.
You are not asked to pay for treatment that the scan says will not work. You even so pay that charge: someone came out, ran the diagnostic and offered you the advice.
Aftercare is taken in by a 30-day warranty: should the light come back within it, an engineer returns to Leonardston.
Id recommend DPF Fixer when your dpf needs cleaning. Daniel who attended to my car was friendly, knowledgeable, explaining what the problem was and how he fixed it. I also needed a replacement sensor which Daniel sorted. A very good service. Thank you.
Great prompt service. Fixed my issue within the hour. Yes expensive at £458 but I was on the road and my van running again. Value for money.
Excellent service ever! They came out at a very needed time. My dpf was badly blocked and the Engineer exercised high patience with it. Great stuff!
The vehicles we clean and the patch we take in near Leonardston
The filter is cleaned in place on all of them: private cars, vans of any size and light commercials, heavy goods vehicles, construction and plant machinery, agricultural vehicles. Nothing is moved anywhere.
Technicians are along Leonardston Road nearly every week, so Leonardston is hardly ever a journey of its own, and the same run takes in Glenowen, Neyland Vale and the places out past Llanstadwell. It is the diary, not the distance, that picks whether it is this day or the next, and coverage extends UK-wide — so ring even from further out through Pembrokeshire.

Common questions on DPF cleaning in Leonardston
- Does a long run sort it?
- Sometimes, if you spot it early and the car has not fallen into limp mode. A sustained run at motorway speed is what it needs — not five minutes or so to Co-op Food and back.
- How long does the visit take?
- Expect typically around 2 hours — severely blocked filters sometimes require a second pass, which extends it.
- The cost in Leonardston — what is it?
- It starts from £299, plus the call-out charge taking in the visit, the scan and the advice. We price on the phone, because the vehicle and your address both change the figure.
- Have I need to be around?
- Somewhere for the vehicle to wait, for a couple of hours, is all that is required. Not you. The regeneration can be run as a watched drive if you would prefer to ride along.
- Travelling to Leonardston — how soon?
- It is often same-day or next-day, depending on what is now in the schedule. One phone call to 0303 330 1830 and you will know what the SA area has free.
- The filter — does it come off the car?
- Not on the mobile service — it is done where it stands. That job — a filter off, a filter back on — is not work we do.
- And if the light comes back?
- Aftercare sits inside the 30-day warranty, and that includes an engineer returning to Leonardston.
