Burnthouse, Cornwall: Mobile DPF Cleaning
The motor sits put — mobile DPF cleaning comes to it. A technician turns up at your place in Burnthouse, treats the diesel particulate filter while it is fitted to the car, carries out a DPF regeneration, and you end up with the filter you came with.
The visit takes typically around 2 hours, the clean opens from £299, and the number is settled over the phone before anyone sets off.
If the light is already on and the vehicle is low on power, this page is for you. That is how most drivers end up here.
Your DPF light is on — what now?
It may not be the filter in the end. That is the main thing. A diagnostic comes before any treatment, because that same panel light has several possible faults behind it.
It counts what you do with the motor between now and the visit.
- Amber light, car even now driving fine — a long steady run can even now sort it by itself. Costs nothing, and worth trying before you book anything.
- That window has shut once the car has fallen into limp mode. Motoring will not help now.
- Diesel smell in the car, or black smoke under acceleration — stop booking long drives and get it checked.
Signs the vehicle has been showing you
By the time the light arrives, things have normally been going wrong for weeks. It is late news:
- power falling off, above all pulling uphill
- revs that will not climb the way they used to
- fuel use going worse
- silently, the stop/start bows out
- the interior reeking of diesel, or smoke when you press on
None of that is conclusive alone. The light with them points at a full filter.
Blocked diesel particulate filters round Burnthouse, and the reason
For a DPF, the poorest motoring is the kind you find around a rural hamlet such as Burnthouse. A regeneration needs long enough and heat, and gets none: not on the school run to Kennall Vale School, not on A393 at half past eight, not on a few minutes to Costcutter, and not on the run to Penryn. Instead of burning away, the soot load builds up.
The M5 stands over 50 miles from Burnthouse, Truro under 10 miles off, and unless something pulls you out that way regularly, entire weeks pass without the long steady run that clears a unit. Geography does not help.
Limp mode, and when DPF regeneration stops working
The motor is looking after itself, which is what limp mode amounts to. Output is capped, the revs will not climb, and the regeneration the filter needs can not happen — which is the entire catch, because a sustained drive works by starting that regeneration.
So the common advice to run it up the motorway is sensible advice, up until the day it is not. Past that line — limp mode — driving will not manage it, and the filter requires cleaning.
The vehicle stays in place for call-out DPF cleaning across Burnthouse
The filter does not come off. That is the part most people do not anticipate: the job is done with the DPF even now fixed to the vehicle, on your driveway, in a work car park, wherever the vehicle can sit for a while.
First a scan. Running ECU data, the soot load as a percent and as a weight, the sensors, the glow plugs, the related components — all of it read before anything is cleaned.
Then the treatment. A cleaning fluid goes in through the access port on that vehicle and expands inside the filter, freeing the soot and ash a regeneration by itself will never move. A second pass is sometimes required on severely loaded filters.
A regeneration is next, burning off what the clean has lifted. Ride along with the vehicle and it turns into a monitored drive out of Burnthouse. Park it and the regeneration runs on the spot, with live data read once it is done.
Then a second scan, verifying the change, clearing the warning light and logging anything still outstanding. Both sets of figures are emailed over, so the before and after figures are recorded.
When a DPF clean is not the solution
A filter choked with soot and ash is the one thing treatment fixes. It will not reach:
- a temperature or pressure sensor flagging a blockage that is not there
- EGR valves that jam open
- a fault in the AdBlue system
- injectors or glow plugs that prevent a regeneration completing whatsoever
- oil working through the filter from a faulty turbo
Which is why the diagnostic goes first. You are let know before any work begins, not after you have paid, should it turns out to be one of those.
DPF renewal is what people look up, but no part is exchanged: the filter you own is cleaned where it sits and put back to work. Nor is having it cut out a fix, since the MOT then fails and driving becomes unlawful. Two more things worth knowing.
Figures for DPF cleaning around Burnthouse
The clean opens from £299. A call-out charge is added to every visit, and covers the call-out itself, the booking, the scan and the advice that goes with it.
The number is settled by the phone, once we know the vehicle and what the filter is apt to need. No flat rate could be honest. What you drive and where you are both move it: Burnthouse itself, out at Lower Treluswell, or further out in the TR postcode area.
Where the check says a clean will not help, you are not asked to pay for cleaning. You even so pay that charge: someone travelled, did the diagnostic and passed on you the advice.
Aftercare is included by a 30-day warranty: should the light return within it, an engineer heads back to Burnthouse.
Couldn't be happier with the service I received. Great communication and friendly knowledgeable staff. Would recommend and use again in the future.
Really helpful on the phone call, didn't have to wait long for an appointment with the engineer, then engineer was great.
Very nice young gentleman he did a good job and his advise was noted and issues that he picked up will be looked in to in the coming weeks.
Vehicles we clean, and where we reach around Burnthouse
Whatever it is — private car, panel van, light commercial, lorry, plant, construction machinery, agricultural vehicle — the same call-out service stands, and the filter never leaves it.
Week in week out there is by then someone on A393, so Burnthouse seldom means a special trip, and Lower Treluswell, Perran Wharf and the villages past Perranarworthal are on the way. It is the schedule, not the distance, that settles whether it is one day or the next, and coverage reaches UK-wide — so phone still from even further out through Cornwall.

What Burnthouse drivers ask about DPF cleaning
- Is a long drive enough alone?
- If you get it early enough, and the car is not in limp mode, sometimes. A steady run at motorway speed is what it takes — not ten minutes to Costcutter and back.
- Roughly how long does it take?
- That is typically around 2 hours, though a heavily blocked filter can need cleaning twice, which runs on.
- How much does it come to around Burnthouse?
- The call-out charge pays for the visit, the diagnostic and the advice; cleaning itself opens from £299. Both the vehicle and where you are move it, which is why quoting goes by phone.
- Is it essential for me to be present?
- Space for the vehicle to stand, for a couple of hours, is all that is required. Not you. Wanting to be there is no problem: the regeneration then runs out on the open road, monitored.
- Getting to Burnthouse — how soon?
- You are offered often same-day or next-day, though it depends what is already in the diary. Phone 0303 330 1830 and we will say to you what is open across the TR area.
- The filter — does it come off the motor?
- It is cleaned where it stands, on the on-site service. We never get filters off or put them back on, either way.
- Suppose the light returns?
- Included by the 30-day warranty: aftercare, and an engineer coming back to Burnthouse.
