Mobile DPF Cleaning serving Lanjew, Cornwall
Treating the DPF takes place at the vehicle, not at a workshop. Your vehicle isn't taken off and the filter does not come off. A fitter comes at your door across Lanjew, clears the diesel particulate filter fitted to the car and performs a DPF regeneration.
You'll know a figure by phone before anyone goes, the clean opening from £299, and the visit running typically around 2 hours.
Most drivers find us with the light already on, and the vehicle low on power. That is the situation this page is aimed at.
What to try when the DPF light comes on
It may not be the DPF whatsoever. That is the main thing. That light can arise from plenty of faults, not only one, so the visit starts with a scan and not with cleaning.
The use you manage in the meantime counts. That is the second thing.
- Vehicle yet driving fine on an amber light — try a long steady run first. It costs nothing at all and frequently shifts the filter without help.
- Car already gone into limp mode — that window has closed. A drive will not shift it now.
- Diesel smell in the cabin, or black smoke under hard acceleration — stop planning long drives and get it checked.
Signs the motor has been sending you
Belated news, the light. The symptoms usually grow for weeks before it appears:
- power falling off, particularly climbing uphill
- revs that will not rise the way they always did
- fuel use that is worse than before
- quietly, the stop/start bows out
- a diesel smell in the cabin, or smoke under acceleration
None of that is evidence on its own. It is a fair bet the filter is loaded once the light is on as well.
The cause diesel particulate filters choke near Lanjew
Lanjew is a small village, and the driving that goes with one is the worst type for a DPF. Nothing of it lasts long enough or is hot enough for the filter to complete a regeneration: the school run to St Wenn School, A30 crawling at half eight, a few minutes to Co-op Food, the hop to Roche. Instead of burning off, the soot banks up.
Neither is far from Lanjew: over 50 miles to the M5, under 25 miles to Truro. Neither is on the way to much most weeks, though, so the drive that would clear a filter hardly ever happens.
The moment a DPF regeneration can no longer complete
The motor is looking after itself, which is what limp mode means. A long drive works by starting a regeneration, and that is exactly what limp mode blocks: power capped, revs kept low, no regeneration available.
So the usual advice to run it up the motorway is sound advice, until it stops being. Once the car is in limp mode you are past that stage, and the filter requires a clean rather than more driving.
Where the vehicle stands is where the DPF is cleaned in Lanjew
Most people do not anticipate this part: the filter stays put. The job happens with the DPF even now fitted to the vehicle — on your front, in a work car park, any place the car can stand for a few hours.
The ECU is read first, showing soot load by percent and by weight, along with a check of sensor feeds, glow plugs and associated parts, so nothing is started while another fault is still possible.
A solution then is fed in through the access point on that motor, expanding inside the filter to loosen soot and ash a regeneration alone will never move. Severely blocked filters sometimes require a second pass.
A regeneration is next, driving off what the clean has lifted. That is a monitored drive out of Lanjew if you are there, or a static regeneration where the motor stands, with the live data read afterwards.
Finally the diagnostic runs again — the change confirmed, the light cleared, anything still showing noted. Both read-outs arrive with you by email, so the numbers are on record.
The problems a DPF clean cannot cure
One thing is what cleaning answers — a filter blocked with soot and ash. It does little for:
- temperature or pressure sensors showing a blockage that is not there
- the EGR valve jammed open
- the AdBlue system going wrong
- glow plugs or injectors preventing the regeneration completing whatsoever
- oil passing through the filter from a failing turbo
That is what the first diagnostic is for. Transpiring to be one of them means finding out it before the work begins, not after handing over anything.
Two things more worth knowing. Having the filter hollowed out is not a solution — a vehicle without a functioning DPF will fail its MOT and driving it is an offence. And cleaning is sometimes described as DPF renewal: nothing is swapped, your existing filter is cleared in place and sent back into use.
Costs for DPF cleaning in Lanjew
Any visit attracts a call-out charge — coming out to you, setting up the booking, running the check and offering the advice. The clean itself opens from £299.
Quoting a flat rate would not be straight. We fix it over phone, once the motor and its likely needs are established. What you run and where you are both move it: Lanjew itself, over at Withiel, or otherwise out across the PL postcode area.
If the diagnostic writes cleaning out, there is no charge to pay for it. The call-out charge still holds, because the visit, the diagnostic and the advice have been done.
A 30-day warranty includes aftercare on the work, and that includes an engineer travelling back out to Lanjew if the light returns inside the window.
Rang them and they came out the same day, done a deep clean on the dpf, so will have to see if it has worked.
The young man was great told me how long he would be sorted it out re set computer and told me about other stuff got it sorted running great I'll give them 5 stars.
Good service! They cleaned up my DPF and fault diagnosed 2 other issues. I went and ordered a new glow plug relay and air mass sensor. Replaced on arrival. cleared the faults with an OBD and voila! All lights out and my van now runs like a stallion! Happy days.
The vehicles we clean and the ground we reach round Lanjew
The one call-out service covers private cars, panel vans and light commercials, HGVs, plant and construction machinery and agricultural machinery, and on every one the filter is treated where it sits rather than carried anywhere.
Lanjew is seldom a special trip: technicians are along A30 week in week out, and the same run covers Withiel, Inchs and the villages out past Roche. It is the diary, not the distance, that settles whether it is one day or the next, and coverage reaches UK-wide — so call anyway from farther out around Cornwall.

Things Lanjew drivers ask about DPF cleaning
- Does a long run sort it?
- If you catch it early enough, and the car is not in limp mode, sometimes. Fifteen minutes to Co-op Food and back will not be enough; motorway speed, kept for a stretch, will.
- The visit takes how long?
- Plan on typically around 2 hours — heavily blocked filters sometimes need a second pass, which extends it.
- The cost around Lanjew — what is it?
- It opens from £299, plus the call-out charge taking in the visit, the check and the advice. We quote on the phone, because the vehicle and your address both shift the number.
- Have I need to be around?
- A spot for the car to sit, for a couple of hours, is all that is required. Not you. If you would sooner come along, the regeneration can be carried out as a monitored drive instead.
- Can someone come to Lanjew soon?
- That comes down to the schedule, but it is often same-day or next-day. Call 0303 330 1830 and you will know what is open across the PL area.
- The filter — does it leave the vehicle?
- On the mobile service, no: the filter is cleaned in place. Neither job — a filter off, a filter back on — is not a job we do.
- The light comes back — then what?
- The 30-day warranty includes aftercare, including an engineer returning to Lanjew.
