Mulfra, Cornwall: Mobile DPF Cleaning
Mobile DPF cleaning comes to the vehicle. A technician turns up at your place across Mulfra, cleans the diesel particulate filter while it is fitted to the motor, performs a DPF regeneration, and you end up with the filter you started with.
You'll know a number by phone before anyone leaves, the clean beginning from £299, and the visit running typically around 2 hours.
If the light is already on and the car is short of power, this page is for you. That is how most people end up here.
What to do when the DPF light is on
It might not be the filter in the end. That is the main thing. Several faults put the identical light on the identical panel, which is why a visit begins with a check rather than with cleaning.
The use you manage in the meantime counts. That is the next thing.
- A long steady run may still manage it, provided the light is amber and the motor drives fine. Costs nothing at all, so attempt that before booking.
- That window has closed once the vehicle has slipped into limp mode. A drive will not do it now.
- Get it looked at rather than driving it — diesel in the interior, or smoke on the throttle, has gone past the long-run stage.
Before the light, what the motor was warning you
Belated news, the light. The symptoms usually mount for a while before it shows:
- less power, especially going uphill
- an engine whose revs will not climb like they did
- fuel economy going worse
- a stop/start that has meekly packed in
- the interior stinking of diesel, or smoke when you pull away
That is not proof on its own. Alongside the light alongside them, the filter is a fair assumption.
Why diesel particulate filters choke near Mulfra
The day-to-day driving that belongs to a rural hamlet like Mulfra is the poorest sort for a DPF. The school run to Trythall Community Primary School, Bone Valley at a standstill at half past eight, a few minutes to Costcutter, the run to Penzance — none of it lasts long enough or is hot enough for the filter to finish a regeneration. Soot that should burn away collects instead.
The M5 stands over 50 miles from Mulfra, Truro under 25 miles away, and unless something pulls you out that way routinely, full weeks go by without the long unbroken run that empties a unit. Geography does not help.
DPF regeneration, and the stage limp mode stops it
Limp mode is the vehicle looking after itself. With pulling power limited and the revs kept low, the regeneration the filter needs cannot happen at all. That counts, because setting off one is precisely what a long run does.
The common advice — get it up the motorway — is sensible, up until it is not. In limp mode you are beyond that stage: a clean is what will work, not more driving.
Mobile DPF cleaning where the motor stands in Mulfra
On your drive, in a work car park, any place the motor can stand for a while: the job takes place with the filter still fitted on, which is the detail most people do not see coming.
First a scan. Live ECU data, the soot load as a percentage and as a weight, the sensors, the glow plugs, the related hardware — all of it logged before anything is started.
A cleaning fluid then goes in through the access point on that motor, opening out inside the filter to lift soot and ash a regeneration on its own will never budge. Where the filter is badly clogged, expect a second pass.
Then a regeneration, to drive off what the clean has loosened. That is a monitored drive out of Mulfra if you are there, or a static regeneration where the car sits, with the real-time data checked after.
Both sets of figures go over by email, so the figures from either end are on record. The second scan is what confirms the change, clears the light and logs whatever is still showing.
What a DPF clean will not cure
One thing is what treatment answers — a filter blocked with soot and ash. It does little for:
- sensors, pressure, reporting a blockage that is not real
- an EGR valve jammed open
- the AdBlue system going wrong
- injectors or glow plugs that block a regeneration running whatsoever
- oil working through the filter from a worn turbo
That is what the first diagnostic is for. Where one of those turns out to be the fault, you learn of it in advance rather than once the money has gone for good.
A couple more worth bearing in mind. Getting the filter cut out is not a solution — a vehicle without a serviceable DPF cannot pass its MOT and driving it is illegal. And cleaning is sometimes searched for as DPF renewal: nothing is swapped, your original filter is cleared in place and returned into use.
The figure for DPF cleaning around Mulfra
Treatment begins from £299, with the call-out charge on top of that for every visit — it takes in the call-out, the booking, the diagnostics and the advice.
Once we have what you drive, and roughly what the filter will take, the number gets settled by phone. A single price for everyone would not be honest. The vehicle shifts it, and so does the postcode — Mulfra, Boskednan, or anywhere farther out in the TR postcode area.
If the diagnostic rules treatment out, there is not a penny to pay for it. You even so pay that charge: someone turned up, did the check and passed on you the advice.
A 30-day warranty takes in aftercare on the work, and that includes an engineer heading back out to Mulfra if the light reappears inside the window.
Absolutely fantastic service from Daniel when he arrived to fix my car, nothing was too much trouble and he took time to explain everything to me, would highly recommend to anyone & would definitely use again. Thank you Dan for a fantastic job.
I can sing nothing but praise for DPF fixer from first initial contacted on Tuesday speaking to Christine organising the appointment to Liam coming out today to sort my daughters car out. The service these gentlemen provided is excellent, definitely recommend.
its been 3 months now and all seems good, the issue has not come back since it was cleaned out, the engineer was really good and explained everything well.
Vehicles we clean, and where we travel round Mulfra
The filter is done where it sits on all of them: cars, vans of any size and light commercials, HGVs, plant machinery, farm vehicles. Nothing is moved anywhere.
Week in week out there is usually someone on Bone Valley, so Mulfra seldom means a journey of its own, and Boskednan, Boswarthen and the places past Madron follow. It is the calendar, not the distance, that settles whether it is today or tomorrow, and coverage extends UK-wide — so ring still from farther out across Cornwall.

Questions Mulfra drivers ask about DPF cleaning
- Is a long drive enough on its own?
- It might, provided you catch it in time and limp mode has not begun. A sustained run at motorway speed is what it needs — not fifteen minutes or so to Costcutter and back.
- The visit runs how long?
- Bank on typically around 2 hours, with a second clean extending that where the filter is severely loaded.
- Around Mulfra, what does it cost?
- Beginning from £299, with a charge for coming out that covers the check and advice on what to do next. Settling it is done by phone, since what you drive and where you live both change the figure.
- Do I have to be present?
- The car requires a space for two hours or so. You need not be in it. Choosing to be there is welcome: the regeneration then is done out on the open road, monitored.
- Can someone travel to Mulfra soon?
- Depending on the diary, often same-day or next-day is typical. Phone 0303 330 1830 and we will let you what is available across the TR area.
- Will the filter be lifted off?
- It is treated where it is, on the on-site service. We do not take filters off or fit them back on, whichever way.
- Suppose the light returns?
- Aftercare sits inside the 30-day warranty, and that includes an engineer returning to Mulfra.
