Plain-an-Gwarry, Cornwall: Mobile DPF Cleaning
Sorting the DPF happens at the vehicle, not at a workshop. An engineer turns up at your door across Plain-an-Gwarry, clears the diesel particulate filter while it is still on the motor, runs a DPF regeneration, and you end up with the filter you came with.
The visit runs typically around 2 hours, the clean starts from £299, and the number is agreed over the phone before anyone sets off.
The light is on already and the car is down on power — that is how we normally come across people, and roughly what this page deals with.
Your DPF light is lit — what then?
It may not be the DPF at all. That is the main thing. A diagnostic comes before the work, because that same dashboard light has several likely faults behind it.
The use you get in the meantime counts. That is the other thing.
- A long constant run may still be enough, provided the light is amber and the motor runs fine. Costs nothing, so try that before ringing.
- A drive will not touch it now — limp mode means that window has already gone.
- Diesel smell in the car, or black smoke under hard acceleration — stop arranging long drives and get it seen to.
Before the light, what the motor was showing you
Late news, the light. The symptoms generally mount for weeks before it arrives:
- falling off on power, particularly uphill
- you find the revs fall short of where they always went
- fuel use getting worse
- the stop/start silently giving up
- a diesel smell in the car, or smoke under hard acceleration
None of that is conclusive by itself. The light with them points at a full filter.
Choked diesel particulate filters near Plain-an-Gwarry, and the cause
The driving that comes with a rural hamlet like Plain-an-Gwarry is the least kind kind for a DPF. Nothing of it runs long enough or is hot enough for the filter to finish a regeneration: the school run to Marazion School, Gears Lane barely moving at half eight, a few minutes to Morrisons, the dash to St Erth. The unburnt soot banks up rather than burning off.
Except when you have a standing reason to get out to the M5, over 50 miles from Plain-an-Gwarry, or across to Truro under 25 miles away, whole weeks go by without a long unbroken run. Geography is no help.
The point a DPF regeneration can no longer complete
Limp mode is the vehicle protecting itself. The whole problem is that a sustained drive works by starting a regeneration, and under limp mode the revs will not rise and power is held down.
Good advice, that motorway run — until the moment it is not. The filter needs a clean rather than road work once the motor has slipped into limp mode.
Where the car stands is where the DPF is treated in Plain-an-Gwarry
Most people do not see coming this part: the filter stays on. The job is done with the DPF still bolted to the car — on your drive, in a work car park, anywhere the vehicle can sit for a couple of hours.
A scan happens first — real-time data off the ECU, soot load by percent and by actual weight, and a check of the sensor readings, glow plugs and associated components, so other faults are ruled out before anything is started.
Soot and ash that a regeneration alone will never shift are loosened second, by a solution put through the access port on that motor, which expands inside the filter. Sometimes a filter is clogged enough to require doing twice.
Next, a regeneration burns off everything the clean freed. Come with the car and it turns into a monitored drive out of Plain-an-Gwarry. Leave it and the regeneration is done on the spot, with running data read once it is done.
A second scan proves the change, clears the warning light and lists anything still showing. Both read-outs are emailed, so you keep the before and after figures recorded.
What a DPF clean will not cure
A filter choked with soot and ash is the one thing a clean cures. It will not reach:
- temperature or pressure sensors reporting a blockage that is not there
- EGR valves that jam open
- the AdBlue system playing up
- glow plugs or injectors preventing the regeneration starting in the first place
- the turbo putting oil into the filter
The first check is there for exactly that. If one of those proves the fault, you hear about it up front rather than once the money has changed hands for good.
Hollowing the filter out is not a solution: without a functioning DPF a vehicle will fail its MOT, and driving it is against the law. DPF renewal is the phrase people look up, though nothing is replaced — your existing filter is cleared in place and put back into use. Two more worth bearing in mind.
Prices for DPF cleaning around Plain-an-Gwarry
Every visit takes a call-out charge — coming out to you, taking the booking, carrying out the diagnostic and giving the advice. The clean itself opens from £299.
Not one flat rate would be honest, so the number is agreed on the phone once we know the vehicle and what the filter is likely to need. Whereabouts you are counts as much as what you own: Plain-an-Gwarry itself, Tregurtha Downs next door, or otherwise out across the TR postcode area.
If the check writes treatment out, there is not a penny to pay for it. Because the visit, the check and the advice have taken place, the call-out charge even so stands.
If the light returns inside that time, an engineer travels back out to Plain-an-Gwarry — the work includes a 30-day warranty taking in aftercare.
Had been quoted £2000 to replace DPF by my garage. DPF came home and fixed it for £400 or so, car runs perfectly now. Great service, highly recommend.

Common questions on DPF cleaning across Plain-an-Gwarry
- Is a long drive enough on its own?
- If you get it in time, and the car is not in limp mode, sometimes. Ten minutes to Morrisons and back will not do it; motorway speed, kept for a stretch, will.
- How long does the visit run?
- Expect typically around 2 hours — heavily loaded filters sometimes take a second pass, which adds to it.
- The cost around Plain-an-Gwarry — what is it?
- The call-out charge pays for the visit, the scan and the advice; the clean itself opens from £299. The vehicle and your address both change the number, so we price on the phone.
- Do I have to be present?
- No. The vehicle requires space to sit for a couple of hours; nobody expects you to stand with it. Preferring to be there is fine: the regeneration then is done out on the road, monitored.
- How soon can someone come to Plain-an-Gwarry?
- That comes down to the diary, but it is often same-day or next-day. Phone 0303 330 1830 what is available across the TR area.
- Is the filter taken off the vehicle?
- Treated where it stands, on this service, so no. Taking a filter off or fitting one back on amount to anything something we do whichever way.
- The light returns — then what?
- Aftercare comes inside the 30-day warranty, and that includes an engineer heading back to Plain-an-Gwarry.
