Mobile DPF Cleaning in Knightor, Cornwall
The workshop to all intents comes to your address in Knightor, and the car stays where it is.
A technician arrives in a fully fitted mobile unit, treats the DPF unit while it is fitted to the car, performs a DPF regeneration, and leaves you with the car you began with. You'll be given the price before anyone is sent out, from £299, and you're without the vehicle for roughly 2 hours.
What an on-site DPF regeneration visit in Knightor entails
Somewhere for the fitted van to sit. An engine that runs at intervals. That's genuinely the whole of it.
After that, it runs the same four steps each time:
- Nothing is touched until a full scan has been carried out and live data pulled from the ECU, giving the soot load by percentage and weight, and testing the sensors, plugs and connected parts.
- Then the cleaning agent goes in at the car's entry point and expands inside the unit, lifting the ash and soot that a regeneration would never have moved on its own.
- At the kerb is the usual, with a monitored trip out of Knightor available if you want to come along, and the regeneration takes care of the lifted deposit regardless.
- Then comes a closing scan. It confirms the change, clears the light out, and writes down anything that's still outstanding.
Sent over once the second scan is complete, both sets of numbers go into the record.
Where the cleaning can be done round Knightor
There is no special need beyond space to park for the length of the job.
Which normally amounts to one of these:
- At home across in Knightor, on the driveway
- A workplace car park
- A quiet corner of a forecourt
- A corner just off Penwithick Park
- The Penwithick P O & Stores car park while you get on with something else
The DPF never comes off the car, so there is no need for you to hang about with it.
Clogged diesel particulate filters round Knightor, and the reason
It's the day-to-day driving rather than the filter, and in a small village such as Knightor that driving is the worst sort for it. The school run to Sky Primary and Eden Project Nursery, the queue on Resugga Green Lane at the morning rush, a few minutes to Penwithick P O & Stores and back, the run to Luxulyan — none of it goes on long enough or climbs hot enough for the filter to complete a burn cycle, so soot that should burn off builds up instead.
Unless you have a routine reason to get out on the M5, over 50 miles from Knightor, or drive over to Truro under 15 miles away, whole weeks slip past without a drive of the sort that empties a filter out.
You'll probably have noticed something already. A smell of diesel inside, dark smoke when you put your foot down, power falling off, revs that won't climb, worse economy, and stop/start giving up without a word. That builds for a while before the light comes on.
What will on-site DPF cleaning not fix?
Cleaning answers a filter choked with soot and ash. All sorts of other failures throw that same light on the same dash, which is why there's a check at the start and nothing is touched until that's finished.
Cleaning will not touch:
- A temperature or pressure sensor reporting a block that is not there
- An EGR valve stuck open
- A failure with the urea system
- Faulty injectors or glow plugs, so no regeneration ever starts
- Turbo problems passing oil into the DPF
Where one of those proves to be the fault, you are told in advance rather than after you have settled up.
You can't escape it by having the unit gutted, either — that's an MOT failure and it's an offence to drive. And nothing gets exchanged: what people look up as DPF renewal is your own filter, cleared in place and put back into service.
Having a go at a sustained run first
A unit only just starting to load up will often sort itself without anyone working on it. over 50 miles sits between Knightor and the M5, and that is the journey to make, keeping the pace even. The scenic route into Truro does too. Ten minutes to Trethurgy and home does not.
Once the light is on and the motor has gone into limp-home mode, that window has gone and an on-site clean is the sensible next step.
On-site DPF cleaning prices around Knightor
Where call-out DPF cleaning begins is from £299. You also pay a call-out on each visit. It pays for the journey, the booking, the scan and the advice you are given.
You'll be given the figure by phone rather than from a list, because the car and the state of the DPF both change it. Tell us what you run and roughly whereabouts you live — Knightor itself, out by Penwithick, or elsewhere in the PL postcode area — and you'll have the price before anyone leaves.
Aftercare is not an add-on; it sits inside the 30-day warranty the work comes with. Where the warning light reappears during the window, an engineer travels back to Knightor.

Our own workshop is not where the job is done. Your door in Knightor is, with the DPF cleaned in place on every one of them.
You will want the other method if the motor will not fire up at all: the DPF comes off, is taken to our premises by courier, and is treated within 24 hours of arrival. Removal and refitting are outside both routes.
At the moment 5 stars had my car done 3 days ago so far so good Liam the mechanic was very professional and polite only took 2 hrs max he gave me maintenance tips leaflet which is useful ill see what the next few weeks bring.
Dan and Rob attended to my vehicle. I was kept informed prior to their arrival. When they arrived they analysed my car and pointed out the faults. They did the job in just over an hour and advised me on post cleaning tips. I thought DPF service was very professional.
Liam has done a great job. All things fully explained and good feedback. Your company has been excellent from the initial phone call. Will definitely recommend you to others.
The PL area and Knightor: our coverage
Penwithick, Treskilling, and the smaller places over past Trethurgy and Rescorla all fall on the same route as Knightor, and our technicians are on Resugga Green Lane most weeks.
Further out across Cornwall, the call is still worth a try. You are not held up by the journey. Coverage runs nationwide, and it is the local schedule that settles whether it is today or tomorrow.
On-site DPF cleaning around Knightor: frequent questions
How long is the job?
About two hours. A badly loaded filter can need a second pass, which extends that.
How much will on-site DPF cleaning cost me around Knightor?
On top of a price starting from £299, the visit, the scan and the steer are met by a call-out. Where you are and what you own both change it, which is why the price arrives by phone.
Do you come out to houses and business premises?
Both, anywhere in Knightor or the broader Cornwall area. The work is done on the motor, in situ, and the filter is never detached.
When can a technician get to Knightor?
What is already booked governs it, but next-day and same-day are routine. What is open across the PL postcode area is something we can tell you the moment you phone 0303 330 1830.
Is there anything to pay if it is found not to be the DPF?
Whatever happens that charge applies, since it covers the journey, the diagnostic and the advice. What you will not get is a bill for cleaning that did not take place.
Am I protected if the dash light comes on again?
The 30-day warranty extends to aftercare, including an engineer returning to Knightor.
How long before I need it repeated?
The driving that follows is what decides it. Out past Truro, or on the M5, is worth far more to the DPF than short hops around Penwithick and back.
