Mobile DPF Cleaning covering Ponsanooth, Cornwall
Cleaning the DPF takes place at the vehicle, not at a workshop. A fitter turns up at your place over in Ponsanooth, clears the diesel particulate filter while it is fitted to the vehicle, runs a DPF regeneration, and you keep the filter you arrived with.
The visit takes typically around 2 hours, the clean begins from £299, and the price is settled on the phone before anyone travels.
Written for the situation most owners are in: the light already on, the vehicle short for power, and the clean still to fix.
What to check when the DPF light shows
The DPF is not always what is wrong, and that comes first. A scan comes before the cleaning, because that same dashboard light has a number of candidate faults behind it.
Second thing: how you drive it between now and then matters.
- Worth a shot before you book anything: amber light, vehicle driving fine, just one even run, no charge.
- Vehicle already dropped into limp mode — that window has shut. A drive will not shift it now.
- A diesel smell in the car, or black smoke under acceleration, is the stage to stop booking long drives and book it in.
What the motor has been warning you
Late news, the light. The symptoms usually grow for a while before it arrives:
- dropping away on power, especially uphill
- revs that will not rise the way they once did
- fuel use getting worse
- stop/start silently bowing out
- the car reeking of diesel, or smoke when you accelerate
By itself, none of that is evidence. With the light with them, the filter is a fair assumption.
Choked diesel particulate filters round Ponsanooth, and the cause
Being a village, Ponsanooth throws up precisely the driving a DPF handles least well. Look at a normal week: Kennall Vale School and home again, St Michael's Road at a crawl before the hour, a quick trip to Costcutter, a dash to Perranwell. Not much there runs long enough or gets hot enough to complete a regeneration. What should burn away remains.
The map does not assist either. The M5 is over 50 miles from Ponsanooth and Truro is under 10 miles away, so unless something carries you out that way routinely, whole weeks go by without the sustained run that would empty the filter alone.
Why limp mode stops a DPF regeneration
It is self-defence: that is all limp mode amounts to. Pulling power is held down, the revs will not climb, and the regeneration the filter requires can never run — which is the entire problem, because a long drive works by triggering that regeneration.
Sound advice, that motorway run — up until the point it is not. Once the vehicle is in limp mode you are past that point, and the filter requires cleaning rather than more driving.
DPF cleaning at the car across Ponsanooth
Most owners do not anticipate this bit: the filter stays put. The job takes place with the DPF yet fixed to the motor — on your front, in a work car park, wherever the motor can wait for a couple of hours.
First a diagnostic. Real-time ECU data, the soot load as a proportion and as a figure, the sensor feeds, the glow plugs, the associated hardware — all of it logged before anything is cleaned.
A cleaning solution next is fed in through the access port on that car, spreading inside the filter to loosen soot and ash a regeneration on its own will never move. A second pass is sometimes needed on heavily loaded filters.
What the clean has lifted is then cleared by a regeneration. Stay with the vehicle and it becomes a monitored drive out of Ponsanooth. Leave it and the regeneration goes on the spot, with live data read once it is done.
Finally the scan runs again — the change verified, the light reset, anything still outstanding written down. Both sets of figures arrive with you by email, so the numbers are on record.
Where treatment is not the answer
A filter clogged with soot and ash is the one thing treatment fixes. It will not touch:
- a temperature or pressure sensor reporting a blockage that is not there
- EGR valves that hang open
- the AdBlue system going wrong
- injectors or glow plugs that block a regeneration completing in the first place
- turbo trouble, with oil entering the filter
That is what the first diagnostic is for. If one of those is the fault, you hear about it at the outset rather than once the money has left already.
DPF renewal is what people type in, but no part is swapped: the filter you already own is treated where it sits and sent back into service. Nor is having it hollowed out a fix, since the MOT then fails and driving becomes illegal. Two more things worth knowing.
DPF cleaning prices around Ponsanooth
Every visit carries a call-out charge — travelling to you, making the booking, doing the check and giving the advice. The clean itself opens from £299.
Quoting a flat rate would not be truthful. We settle it over phone, once the motor and its expected needs are known. A pair of things shift it: what you own, and where you are — Ponsanooth itself, over at Burnthouse, or otherwise out in the TR postcode area.
Where the scan says a clean will not work, you are not charged for a clean. What nonetheless stands is the call-out charge, since the visit was made, the diagnostic was run and the advice was given.
A 30-day warranty covers aftercare on the job, and that includes an engineer travelling back out to Ponsanooth if the light reappears inside the window.
Andras was excellent in explaining everything he was doing as it took him some time to determine the source of the fault-great patience and persistence. I have no qualms in recommending DPF Fixer. First rate service!
Really impressed with this! Very easy to arrange, really helpful chap called Andras who carried out the clean and diagnostics, and much much cheaper than replacing the filter so saved me a lot of money. Highly recommended.
Professional, friendly and fast service. Daz done really good job. My car is now running smoothly and all power back with DPF cleaned and all faults erased. Thank you!
Where we travel round Ponsanooth, and what we clean
A single mobile service covers cars, vans of any size and light commercials, HGVs, construction and plant machinery and agricultural machinery, and on every one the filter is treated on the vehicle rather than taken anywhere.
Engineers are along St Michael's Road nearly every week, so Ponsanooth is seldom a special trip, and the same run takes in Burnthouse, Perranarworthal and the villages out past Frogpool. Ring anyway from farther out around Cornwall. Coverage extends UK-wide, and the day you are offered depends on the schedule rather than how far away you are.

What Ponsanooth drivers ask about DPF cleaning
- Does a long run clear it?
- Quickly enough, and with the motor out of limp mode, yes — sometimes. It needs a long run at motorway speed, not ten minutes to Costcutter and back.
- Does the visit run long?
- That is typically around 2 hours, though a heavily blocked filter can require cleaning twice, which runs on.
- What does it cost across Ponsanooth?
- The call-out charge covers the visit, the diagnostic and the advice; the clean itself starts from £299. The vehicle and your address both change the price, so we settle it on the phone.
- Must I be there in person?
- Nobody expects you to stand with it — the car only needs somewhere to stand for a couple of hours. If you would sooner come along, the regeneration can be carried out as a monitored drive instead.
- When can someone get to Ponsanooth?
- You are offered often same-day or next-day, though it depends what is currently in the schedule. One phone call to 0303 330 1830 and you will learn what the TR area has available.
- The filter — does it come off the car?
- On the on-site service, no: the filter is cleaned in place. We will not lift filters off or fit them back on, in either direction.
- The light comes back — then what?
- The 30-day warranty includes aftercare, including an engineer coming back to Ponsanooth.
