Mobile DPF Cleaning in Tregatillian and Cornwall
The motor remains put — on-site DPF cleaning comes to it. No garage, no filter leaving. A fitter drives out to your door in Tregatillian, cleans the diesel particulate filter where it is, runs a DPF regeneration, and you end up with the filter you arrived with.
You'll know a figure by phone before anyone departs, the clean opening from £299, and the visit lasting typically around 2 hours.
Most owners find us with the light showing, and the car down on power. That is the situation this page is written for.
What to check when the DPF light is on
It might not be the filter at all. That is the first thing. That light can arise from plenty of faults, not only one, so the visit begins with a diagnostic and not with cleaning.
The driving you do in the meantime tells. That is the second thing.
- Car even now driving as normal on an amber light — attempt a long steady run first. It costs nothing and regularly sorts the filter without a visit.
- Once the vehicle is in limp mode, a long run will not touch it. The window has closed.
- A diesel smell inside, or black smoke under the throttle, is the moment to stop planning long drives and book it in.
What the car has been telling you
The light is belated news. By the time it shows, the symptoms have generally been building for a while:
- going uphill, the power drops away
- you notice the revs stop short of where they used to go
- worse fuel economy
- a stop/start that has meekly packed in
- smoke under hard acceleration, or a diesel smell in there
Any one of those, taken alone, is not evidence. It is a fair assumption the filter is blocked once the light is there too.
What chokes diesel particulate filters around Tregatillian
The day-to-day driving that goes with a small village like Tregatillian is the least kind type for a DPF. Run through a typical week: St Columb Major Academy and back, Union Hill at a standstill before the hour, a short hop to The Co-operative Food, a run to St Columb Road. Nothing there lasts long enough or is hot enough to finish a regeneration. What should burn away stays behind.
The M5 lies over 50 miles from Tregatillian, Truro under 15 miles away, and unless something takes you out that way routinely, full weeks go by without the sustained run that clears a unit. Geography does not oblige.
The point a DPF regeneration can no longer run
Limp mode is the car protecting itself. With power capped and the revs kept low, the regeneration the filter requires will not run at all. That counts, because triggering one is just what a long run does.
Taking it up the motorway is the common advice, and it holds up to a point. Once the car is in limp mode you are the far side of that stage, and the filter requires cleaning rather than driving.
Where the motor stands is where the DPF is cleaned across Tregatillian
On your driveway, in a work car park, anywhere the motor can stand for a couple of hours: the job is done with the filter still fixed on, which is the detail most drivers do not expect.
Nothing is touched until other faults are ruled out. That means a diagnostic first: live data off the ECU, soot load by proportion and by actual weight, and a check of the sensor feeds, glow plugs and associated hardware.
Then comes the clean itself: cleaning fluid in through the vehicle's own entry point, opening out inside the filter and loosening what a regeneration cannot. Sometimes a filter is loaded enough to need doing twice.
What the clean has loosened is then cleared by a regeneration. That is a monitored drive out of Tregatillian if you are along, or a static regeneration where the vehicle sits, with the real-time data read afterwards.
Finally the diagnostic runs again — the change verified, the light reset, anything still showing logged. Both read-outs reach you by email, so the numbers are on record.
Where treatment is not the answer
Only one fault is cured by a clean: the filter choked with ash and soot. It does no good for:
- sensors, temperature or pressure, showing a restriction that is not real
- EGR valves that stick open
- the AdBlue system failing
- glow plugs or injectors preventing the regeneration completing in the first place
- a turbo putting oil through the filter
The first check is there for just that. Where it proves to be one of those, you are told before any work starts rather than after you have paid a penny.
Two things more worth knowing. Leaving the filter hollowed out is not a remedy — a vehicle without a functioning DPF cannot pass its MOT and driving it is against the law. And cleaning is sometimes searched for as DPF renewal: nothing is exchanged, your own filter is cleared in place and sent back into use.
The price of DPF cleaning in Tregatillian
The clean opens from £299. A call-out charge is added to every visit, and takes in the call-out itself, the booking, the diagnostic and the advice that follows.
The figure is settled over the phone, once we know the vehicle and what the filter is going to need. No flat rate could be truthful. What you own and where you are both move it: Tregatillian itself, out at Quoit, or farther out in the TR postcode area.
You are not billed for cleaning that the check says will not do it. You even so pay that charge: someone turned up, carried out the diagnostic and offered you the advice.
The job carries a 30-day warranty including aftercare, including an engineer travelling back out to Tregatillian if the light returns inside that window.
Had plenty of issues with my car. Had a full DPF today on my car. I only called today and got a same day appointment. The gentleman who came out was amazing. I would highly recommend.
Fantastic service, came within 3 hours, Igor is a very knowledgeable polite mechanic. The car runs like a dream. Thank you.
Huge thank you to Carolina and Andras for an exceptionally efficient and prompt service. 4 hours from the time I placed my initial call to the DPF being cleaned. We'll definitely be using you again.
Vehicles we clean, and where we travel round Tregatillian
Cars, vans of any size and light commercials, HGVs, construction and plant machinery, agricultural vehicles — a single on-site service across all of them, and on all of them the filter is done where it sits rather than moved anywhere.
Tregatillian is rarely a special trip: technicians are along Union Hill nearly every week, and the same run takes in Quoit, St Columb Major and the places out past Trevarren. Call anyway from farther out around Cornwall. Coverage extends UK-wide, and the slot you are given hangs on the calendar rather than how far away you are.

Questions Tregatillian drivers ask about DPF cleaning
- Can I simply take it for a long drive?
- Soon enough, and with the car out of limp mode, yes — sometimes. Fifteen minutes to The Co-operative Food and back will not do it; motorway speed, sustained for a stretch, will.
- Does the visit take long?
- Bank on typically around 2 hours, with a second clean extending that where the filter is severely blocked.
- How much does it cost in Tregatillian?
- A clean opens from £299, and the call-out charge on top covers the visit, the scan and the advice. Both the vehicle and where you are move it, which is why settling it goes by phone.
- Must I be present in person?
- No. The car wants somewhere to stand for a couple of hours; nobody expects you to stand with it. Choosing to be there is fine: the regeneration then is done out on the move, monitored.
- Travelling to Tregatillian — how soon?
- It is often same-day or next-day, depending on what is now in the schedule. Call 0303 330 1830 and we will say to you what is free across the TR area.
- The filter — does it come off the motor?
- It is done where it sits, on the on-site service. We never take filters off or fit them back on, whichever way.
- The light returns — then what?
- An engineer heads back out to Tregatillian — the 30-day warranty includes aftercare.
