Mobile DPF Cleaning in Mount Charles and Cornwall
Call-out DPF cleaning comes to the motor. The technician pulls up at your place across Mount Charles and gets to work. The diesel particulate filter is cleared on the car, a DPF regeneration follows, and you keep the filter you came with.
The visit takes typically around 2 hours, the clean starts from £299, and the price is agreed over the phone before anyone leaves.
Most people find us with the light on already, and the car down on power. That is the situation this page is meant for.
What to try when the DPF light comes on
First thing: it is not always the unit. Several faults put the identical light on the same panel, which is why a visit opens with a diagnostic rather than with treatment.
Second thing: how you run it between now and then matters.
- A long even run may still do it, provided the light is amber and the motor goes fine. Costs nothing at all, so have a go at that before ringing.
- A drive will not reach it now — limp mode means that window has already closed.
- Stop booking long drives and get it checked if the interior reeks of diesel or there is black smoke when you press on.
The vehicle has been warning you already
Symptoms have generally been growing for weeks before the light so much as arrives. Belated news, in other words:
- climbing uphill, the power tails off
- the revs no longer rise the way they once did
- fuel economy turning worse
- the stop/start without a word packing in
- smoke under hard acceleration, or a diesel smell inside
Alone, none of that is conclusive. It is a fair bet the filter is full once the light is showing too.
The explanation diesel particulate filters clog near Mount Charles
Mount Charles is a small village, and the day-to-day driving that belongs to one is the poorest type for a DPF. The school run to Nanstallon Community Primary School, B3266 at a halt at the morning rush, a few minutes to Sainsbury's, the run to Bodmin Parkway — nothing of it runs long enough or is hot enough for the filter to complete a regeneration. The soot that should burn off banks up instead.
Unless you have a standing cause to drive out to the M5, over 50 miles from Mount Charles, or out to Truro under 25 miles away, whole weeks go by without a long unbroken run. Geography is no help.
DPF regeneration, and the point limp mode ends it
It is self-defence: that is all limp mode amounts to. The whole difficulty is that a sustained drive works by setting off a regeneration, and under limp mode the revs will not pull and power is limited.
The common advice — run it up the motorway — is sensible, up until it is not. The filter wants a clean rather than more driving once the motor has slipped into limp mode.
DPF cleaning at the car across Mount Charles
The filter does not budge. That is the bit most people do not see coming: the job takes place with the DPF even now fitted to the vehicle, on your driveway, in a work car park, any place the car can sit for a couple of hours.
The ECU is interrogated first, reporting soot load by percent and by weight, along with a look over of sensors, glow plugs and related components, so nothing is started while another fault is still open.
A cleaning solution next is fed in through the access point on that vehicle, opening out inside the filter to free soot and ash a regeneration alone will never shift. Where the filter is heavily clogged, allow for a second pass.
A regeneration comes next, clearing what the clean has loosened. Come with the vehicle and it is done as a monitored drive out of Mount Charles. Drop it and the regeneration goes in place, with live data verified once it is done.
Then a second check, verifying the change, clearing the warning light and listing anything still outstanding. Both reports are sent over, so the before and after figures are kept.
Where treatment is not the solution
One thing is what treatment fixes — a filter choked with soot and ash. It does no good for:
- sensors, pressure, reporting a restriction that is not real
- a failed EGR valve
- an AdBlue system failure
- glow plugs or injectors preventing the regeneration starting whatsoever
- a turbo passing oil through the filter
Which is why the check comes first. When one of those proves the fault, you find out about it at the outset rather than once the money has gone for good.
Gutting the filter out is not a remedy: without a functioning DPF a vehicle fails its MOT, and driving it is an offence. DPF renewal is the wording people search for, though nothing is swapped — your own filter is cleaned in place and returned into use. Two more worth noting.
What DPF cleaning runs to across Mount Charles
Cleaning starts from £299, with the call-out charge on top of that for every visit — it pays for the call-out, the booking, the checks and the advice.
The number is settled on the phone, once we are told the vehicle and what the filter is going to need. No flat rate could be straight. The place you are counts as much as what you run: Mount Charles itself, Lane-end next door, or further out across the PL postcode area.
Where the scan says cleaning will not do it, you are not charged for treatment. What even so applies is the call-out charge, since the visit happened, the check was done and the advice was offered.
Aftercare is taken in by a 30-day warranty: should the light return within it, an engineer comes back to Mount Charles.
Don't waste your time looking any further - these guys are the Real Deal! Excellent communication and outstanding customer service. Our engineer Andras, was polite, extremely knowledgeable, and an absolute pleasure to have working on our car. Great company, great staff, thank you all so much! Regards. Dean.
Managed to clean the DPF in my Range Rover Evoque whilst in limp mode and get it back on the road in 2 hours. Ashley was knowledgeable and did a cracking job.
Mechanic who did the dpf cleaning was really good at his job, explained everything he was doing and gave me some pointers on keeping the dpf cleaner for longer. It is pricey but cheaper than replacing the dpf.
Where we get to around Mount Charles, and what we clean
Whatever it is — car, van, light commercial, HGV, plant, construction machinery, agricultural machine — the one on-site service holds, and the filter never leaves it.
Week in week out there is already someone on B3266, so Mount Charles rarely means a journey of its own, and Lane-end, Dunmere and the spots past Nanstallon follow. Coverage reaches UK-wide, so farther out across Cornwall is still worth a phone call, and what picks between today and tomorrow is the diary rather than the distance.

Questions Mount Charles drivers ask about DPF cleaning
- Does a long run clear it?
- Sometimes, if you spot it early and the motor has not fallen into limp mode. It wants a long run at motorway speed, not fifteen minutes flat to Sainsbury's and back.
- Does the visit run long?
- That is typically around 2 hours, though a severely loaded filter can take cleaning twice, which takes longer.
- In Mount Charles, what does it run to?
- It starts from £299, plus the call-out charge paying for the visit, the check and the advice. The vehicle and your address both change the figure, so we quote on the phone.
- Is it needed for me to be there?
- Somewhere for the vehicle to sit, for a couple of hours, is all that is wanted. Not you. If you would prefer to come along, the regeneration can be carried out as a monitored drive instead.
- Coming to Mount Charles — how soon?
- It is often same-day or next-day, depending on what is already in the schedule. Phone 0303 330 1830 and you will hear what is available across the PL area.
- Will the filter be taken off?
- On the on-site service, no: the filter is treated in place. We do not take filters off or fit them back on, either way.
- Suppose the light reappears?
- Aftercare falls inside the 30-day warranty, and that includes an engineer returning to Mount Charles.
