Mobile DPF Cleaning in Porthcothan and Cornwall
Sorting the DPF is done at the vehicle, not at a body shop. No garage, no filter coming off. A technician travels to your address over in Porthcothan, clears the diesel particulate filter where it is, carries out a DPF regeneration, and you hold on to the filter you arrived with.
The visit runs typically around 2 hours, the clean starts from £299, and the number is fixed over the phone before anyone sets off.
Most drivers find us with the light showing, and the vehicle short of power. That is exactly what this page is aimed at.
DPF light on? What to do
Not the DPF, always. Main thing to get straight. Treatment is not where a visit begins. A check is — several faults show up as the same light.
It tells what you get with the vehicle between now and the visit.
- Vehicle still driving normally on an amber light — try a long steady run first. It costs nothing and often clears the filter without help.
- That window has gone once the vehicle has dropped into limp mode. A drive will not help now.
- Diesel smell in the cabin, or black smoke under acceleration — stop arranging long drives and get it seen to.
Signs the car has been showing you
By the time the light arrives, things have generally been deteriorating for some time. It is last news:
- less power, especially pulling uphill
- an engine whose revs will not rise like they did
- fuel use going worse
- silently, the stop/start gives up
- smoke under hard acceleration, or a diesel smell in the car
That is not evidence on its own. Alongside the light, it is a fair assumption the filter is full.
What blocks diesel particulate filters round Porthcothan
Being a coastal village, Porthcothan produces exactly the motoring a DPF copes with the poorest. The school run to St Merryn School, B3276 at a crawl at half eight, ten minutes to Tesco, the run to Newquay — not one bit of it goes on long enough or runs hot enough for the filter to see through a regeneration. What should clear stays put.
Save when you have a routine need to drive out to the M5, over 50 miles from Porthcothan, or out to Truro under 25 miles away, entire weeks pass without a long steady run. Geography is against you.
Limp mode, and when DPF regeneration stops working
The motor is defending itself, which is what limp mode means. A sustained drive works by setting off a regeneration, and that is just what limp mode rules out: power capped, revs pinned, no regeneration available.
The usual advice — run it up the motorway — is sensible, until it is not. The filter wants cleaning rather than driving once the car has dropped into limp mode.
DPF cleaning at the car in Porthcothan
On your front, in a work car park, wherever the motor can stand for a couple of hours: the job is done with the filter still bolted on, which is the bit most owners do not expect.
A scan happens first — running data off the ECU, soot load by percent and by actual weight, and a check of the sensor feeds, glow plugs and related hardware, so other faults are eliminated before anything is cleaned.
Soot and ash that a regeneration on its own will never shift are lifted after that, by a cleaning fluid fed through the entry point on that motor, which expands inside the filter. A second pass is sometimes needed on severely loaded filters.
Then a regeneration, to clear what the clean has freed. That is a monitored drive out of Porthcothan if you are along, or a static regeneration where the car stands, with the real-time data read afterwards.
Finally the scan runs again — the change confirmed, the light put out, anything still open noted. Both read-outs reach you by email, so the numbers are kept.
What a DPF clean will not cure
Only one fault is answered by a clean: the filter choked with ash and soot. It does no good for:
- the wrong figure from a pressure or temperature sensor
- an EGR valve held open
- an AdBlue system problem
- injectors or glow plugs that stop a regeneration completing whatsoever
- a turbo pushing oil through the filter
The first check is there for precisely that. When it proves to be one of those, you are told before any work begins rather than after you have paid for it.
Lastly, two things. A vehicle with the filter hollowed out fails its MOT, and driving it is an offence, so that is no solution. What gets searched for as DPF renewal replaces nothing: your existing filter is cleared in place and goes back into use.
DPF cleaning charges across Porthcothan
Each visit takes a call-out charge — coming out to you, setting up the booking, carrying out the check and passing on the advice. The clean itself opens from £299.
Quoting a flat rate would not be straight. We fix it over phone, once the motor and its likely needs are established. The car moves it, and so does the location — Porthcothan, Penrose, or anywhere otherwise out in the PL postcode area.
Where the check says a clean will not do it, you are not charged for treatment. Because the visit, the scan and the advice have happened, the call-out charge nonetheless applies.
Aftercare is included by a 30-day warranty: should the light return within it, an engineer returns to Porthcothan.

The vehicles we clean and the ground we reach around Porthcothan
The one call-out service covers cars, vans of any size and light commercials, heavy goods vehicles, construction and plant machinery and agricultural machinery, and on every one the filter is done on the vehicle rather than carried anywhere.
The same trip that has technicians on B3276 most weeks picks up Porthcothan, Penrose, Engollan and the villages beyond Treyarnon. It is the calendar, not the distance, that settles whether it is this day or the next, and coverage runs UK-wide — so phone even from farther out around Cornwall.

Questions Porthcothan drivers ask about DPF cleaning
- Will a long drive sort it?
- Sometimes, if you catch it early and the vehicle has not fallen into limp mode. Ten minutes to Tesco and back will not manage it; motorway speed, kept for a while, will.
- About how long does it take?
- It is typically around 2 hours. A heavily loaded filter can need a second clean, which adds to that.
- What does it come to in Porthcothan?
- The call-out charge takes in the visit, the diagnostic and the advice; treatment itself starts from £299. Quoting is done by phone, since what you drive and where you are both change the figure.
- Is it essential for me to be around?
- A spot for the car to wait, for a couple of hours, is all that is wanted. Not you. If you would prefer to come along, the regeneration can be run as a supervised drive instead.
- Can someone come to Porthcothan soon?
- It is often same-day or next-day, depending on what is currently in the schedule. Phone 0303 330 1830 and you will hear what is available across the PL area.
- Does the filter come off the vehicle?
- It is treated where it is, on the on-site service. Getting a filter off or bolting one back on come to anything work we do in either direction.
- What if the light returns?
- The 30-day warranty includes aftercare, including an engineer coming back to Porthcothan.
