Mobile DPF Cleaning serving Crowntown, Cornwall
On-site DPF cleaning goes to the motor. Your motor will not be taken anywhere and the filter will not come off. A technician turns up at your address in Crowntown, cleans the diesel particulate filter still on the vehicle and performs a DPF regeneration.
Allow for the visit running typically around 2 hours. The clean starts from £299, agreed on the phone before anyone sets off.
Most drivers find us with the light already on, and the motor down on power. That is exactly what this page is written for.
Your DPF light is on — what now?
The unit is not always what is to blame, and that goes first. A diagnostic goes before any work, because that same dashboard light has several possible faults behind it.
The use you manage in the meantime counts. That is the next thing.
- Amber light, motor even now driving normally — a long steady run can even now clear it by itself. Costs nothing, and worth attempting before you ring anything.
- Once the car is in limp mode, a long run will not reach it. The window has gone.
- Stop booking long drives and get it looked at if the interior smells of diesel or there is black smoke when you pull away.
The motor has been warning you already
Belated news, the light. The symptoms generally grow for a while before it shows:
- falling off on power, especially uphill
- an engine whose revs will not rise as they should
- worse fuel consumption
- a stop/start that has quietly given up
- diesel in the cabin, or smoke on the way up through the gears
That is not conclusive on its own. The light alongside them points at a full filter.
The explanation diesel particulate filters block near Crowntown
Being a rural hamlet, Crowntown generates precisely the use a DPF copes with worst. Not one bit of it runs long enough or gets hot enough for the filter to complete a regeneration: the school run to Sithney Community Primary School, B3303 barely moving at half past eight, ten minutes to Lidl, the dash to Camborne. Instead of burning off, the soot banks up.
Neither is distant from Crowntown: over 50 miles to the M5, under 15 miles to Truro. Neither is on the way to anything most weeks, though, so the journey that would scour a filter simply never gets made.
DPF regeneration, and the stage limp mode ends it
Limp mode is the car looking after itself. Pulling power is capped, the revs will not rise, and the regeneration the filter requires can never run — which is the whole difficulty, because a sustained drive works by setting off that regeneration.
The standard advice — take it up the motorway — is sound, until it is not. Once the vehicle is in limp mode you are the far side of that line, and the filter needs treatment rather than road work.
DPF cleaning at the vehicle in Crowntown
On your drive, in a work car park, any place the car can sit for a few hours: the job happens with the filter still bolted on, which is the detail most people do not expect.
The ECU is read first, showing soot load by percent and by weight, along with a look over of sensor readings, glow plugs and associated components, so nothing is cleaned while another fault is still possible.
Next comes the clean itself: cleaning fluid in through the vehicle's own access point, opening out inside the filter and lifting what a regeneration will not. Badly blocked filters sometimes take a second pass.
A regeneration is next, driving off what the clean has lifted. If you are there, that is done as a monitored drive out of Crowntown; if not, statically where the motor waits, with the live data checked after.
A second check verifies the change, puts out the warning light and logs anything still showing. Both sets of figures are emailed over, so you have the before and after figures on record.
The faults a DPF clean cannot fix
Only one fault is cured by cleaning: the filter blocked with ash and soot. It does no good for:
- a temperature or pressure sensor showing a restriction that is not there
- EGR valves that jam open
- an AdBlue system fault
- injectors or glow plugs that block a regeneration completing whatsoever
- a turbo putting oil through the filter
That is what the first scan is for. When one of those turns out to be the fault, you learn of it at the outset rather than once the money has left altogether.
Two things more worth knowing. Getting the filter hollowed out is not a fix — a vehicle without a functioning DPF fails 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 put back into use.
The cost for DPF cleaning around Crowntown
The treatment starts from £299. A call-out charge covers every visit, and takes in the call-out itself, the booking, the check and the advice that goes with it.
Once we have what you drive, and about what the filter will take, the price gets fixed by phone. A single price for every job would not be honest. Two things move it: what you own, and where you are — Crowntown itself, over at Prospidnick, or further out within the TR postcode area.
A clean that will not work is not treatment you pay for, and the diagnostic is what says so. What even so holds is the call-out charge, since the visit took place, the diagnostic was run and the advice was offered.
The job carries a 30-day warranty covering aftercare, including an engineer coming back out to Crowntown if the light comes back inside that window.
Great and speedy service. DPF now completely clean and running smooth. Liam who did the clean was friendly, and very informative of the process. Would recommend these guys.
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.
Absolutely spot on service, Chris travelled all the way from Wrexham to Lytham St Anne's. Spent a few hours on my car, no issues since. Service from the booking office easy and hassle free and friendly. Can't recommend them enough.
Where we get to around Crowntown, and what we clean
Whatever it is — car, light van, light commercial, lorry, plant, construction machinery, agricultural machine — the same call-out service applies, and the filter never leaves it.
Crowntown is seldom a special trip: our engineers are working B3303 most weeks, and the same run takes in Prospidnick, Sithney and the spots out past Nancegollan. It is the calendar, not the distance, that settles whether it is one day or the next, and coverage reaches UK-wide — so call still from further out across Cornwall.

What Crowntown drivers ask about DPF cleaning
- Is a long drive enough on its own?
- If you spot it early, and the motor is not in limp mode, sometimes. A sustained run at motorway speed is what it needs — not ten minutes flat to Lidl and back.
- Roughly how long does it last?
- Expect typically around 2 hours — heavily blocked filters sometimes require a second pass, which adds to it.
- How much does it come to across Crowntown?
- Starting from £299, with a charge for coming out that pays for the scan and advice on what to do next. Pricing is done by phone, since what you run and where you are both move the price.
- Must I be present in person?
- Nobody expects you to stand with it — the car only wants a spot to wait for a couple of hours. The regeneration can be done as a monitored drive if you would prefer to ride along.
- Travelling to Crowntown — how soon?
- It is often same-day or next-day, depending on what is now in the schedule. Call 0303 330 1830 and you will learn what is open across the TR area.
- Is the filter taken off the vehicle?
- It is treated where it sits, on the on-site service. Taking a filter off or putting one back on amount to anything a job we do whichever way.
- What if the light comes back?
- Included by the 30-day warranty: aftercare, and an engineer travelling back to Crowntown.
