The Knab Mobile DPF Cleaning, Swansea
When the DPF warning light is lit and you are out in The Knab, on-site DPF cleaning is the direct route out of it. First an engineer arrives at your address across in The Knab. Cleaning the DPF happens with it attached to the vehicle, and a DPF regeneration is run before anyone leaves. You keep the vehicle the whole way through, and nothing on it is removed.
Phone 0303 330 1830 and our engineers will go through a handful of questions about what the car is doing. Once we have that clear, we will quote you the number and book a visit. The opening price is from £299 across The Knab, and most visits are wrapped up within 2 hours on site.
Filters block here down to the way people get about, not down to anything odd about the place. It genuinely surprises us the number of DPF jobs Mobile DPF Cleaner The Knab does around The Knab, given a head count of only around 720. You will typically be looking at that same day or the next, wherever you are across The Knab or the rest of the SA postcode area, according to what is booked. 7.30am to 6.30pm from Monday to Thursday, and 7.30am to 5.30pm on Fridays — those are the hours on the phones. The service itself runs seven days a week.
Blocked diesel particulate filters in The Knab, and the reason
A DPF handles worst short, cold, stop-start journeys. Those are the trips a coastal area such as The Knab produces. Soot that ought to burn off piles up instead, because the filter never completes a burn cycle. Not on the way over to the local primary school, not sat in the queue on Mumbles Road at the morning rush, not running to M&S Food for a few minutes, and not on the quick hop to Swansea.
A great many calls arrive from The Knab, and from Limeslade and Oystermouth a little further on. Geography is behind it: with the M4 under 10 miles away and Swansea under 5 miles off, the long unbroken drive that would empty a unit on its own is not one most people take in a given week.
The light is late news. Long before it shows, power and acceleration have fallen off, the revs have given up climbing properly, fuel consumption has got appreciably heavier, auto stop/start has silently stopped working, and there is sometimes a diesel tang in the cabin or black smoke on acceleration. A warning light that stops again by itself has still told you something worth acting on.
So what actually takes place during an on-site DPF clean in The Knab?
Here is what follows when the van arrives, whether it is your own drive, a yard on Clifton Terrace, or the M&S Food customer car park while you do something else.
- Nothing is fetched from a depot. Everything the job needs travels with the technician, in a kitted-out van. Before any treatment starts, a fault read is taken and live readings drawn from the engine ECU. You get a proper number rather than an estimate: how loaded the DPF is by percentage and by soot weight, with the sensor feeds, glow plugs and related hardware checked alongside it. A dashboard light by itself does not prove the DPF is to blame.
- Ash and soot that regeneration would never clear get loosened first. A cleaning fluid is fed in through the best injection point on the vehicle and spreads inside the unit. A badly clogged DPF may require a second pass.
- A DPF regeneration run then clears off whatever is left. A stationary regeneration is run on site if you would sooner not be present, with the live figures checked afterwards. If you are about and are happy coming along, it can instead be done dynamically, on a monitored run out of The Knab — the type of run the DPF has been going without. Any fault codes still outstanding are flagged at that point, once a follow-up scan has confirmed the result and extinguished the dash light.
You only have to arrange somewhere the car can wait for the duration, with the engine itself ticking over at points. Driveway, office car park, or somewhere quiet near Limeslade Beach — any of those around The Knab will do, and you are free to leave it there.
How do you know the diesel particulate filter is the fault?
The questions on the phone are not small talk. They are how we work out whether cleaning the DPF will solve what you are describing, and how the quote is arrived at. A price is given first on every job, and only then is an engineer sent out to The Knab.
One thing is solved by a cleaning: a filter that is clogged. You should not assume every warning light is answered by a cleaning. Turbos, injectors, AdBlue systems, EGR valves, the glow plugs and sensors all throw up trouble that a DPF treatment will do nothing for. The pre-clean check distinguishes the two, and anything we find gets flagged prior to the cleaning rather than after you have settled up.
DPF regeneration, and when it is not the whole answer alone
Where a diesel particulate filter is only just starting to load up, a long journey empties it, and that is worth attempting first. Allow it under 10 miles out of The Knab to the M4 and hold a steady pace, or take the long way into Swansea. What will not do it is another five minutes to Caswell. There is a soot load beyond which a regeneration alone will not empty the DPF, and reduced power with the light on means you are beyond it. An on-site visit in The Knab is the next step.
Two things worth noting up front:
- Having the DPF cored out is not a solution. A vehicle without a working DPF cannot pass its MOT, and using it is an offence.
- DPF renewal is what people commonly look up, but nothing is renewed. Your original DPF is treated in situ when a technician comes to you, and returned back to doing its job.
There is one case, and it is a vehicle that will not fire up at all — the on-site method in The Knab is no use then. The work then happens at our own workshop instead, within a day of the DPF landing, with overnight carriage back. Getting it packed up and on to a driver is down to whoever removes it. You will need a garage to get the filter off and fit it again, on either service.
What mobile DPF cleaning costs across The Knab
You are paying from from £299 for mobile DPF regeneration. The motor and the state of the filter both move what a job adds up to, which is why no flat price is posted and why the figure is given to you over the phone instead. It helps to tell us approximately where you are — The Knab centre, up towards The Big Apple, out by Limeslade, or somewhere else in the SA area — and what you run, because both move the figure. Nobody is sent until you know the number agreed.
A 30-day warranty sits behind the work, follow-up covered, once the clean is done. The question everybody wants to know is what happens if the light returns. It is answered by an engineer returning to The Knab during the period, which is worth a good deal more than a logo on a website.

Diesel particulate filter cleaning around The Knab, on any vehicle
Whatever you drive, the on-site visit covers it: cars, vans and light commercial vehicles, HGVs, plant and construction machinery, agricultural machinery. Treating in place is the method on each one, and it happens at your premises rather than ours.
Our vans are down Mumbles Road most weeks, and they serve The Knab and all the villages round it — Limeslade, Oystermouth, and over past Caswell and Manselfield. Coverage reaches across the UK, so if you are not far from The Knab or elsewhere in Swansea it is still worth ringing.
You are forwarded both diagnostic sets of figures, from before the work and after it, together with advice geared to how the vehicle actually gets driven around The Knab. That last part is what prevents the unit from blocking again.
A clogged catalytic converter is a different failure with different warning signs — flat response, a sulphur or rotten-egg smell, unusual warmth underneath, and commonly a P0420 fault code. Worth separating the two, because they get confused, and Mobile DPF Cleaner The Knab cleans catalytic converters on the vehicle too.

Frequent DPF cleaning queries around The Knab
Will DPF cleaning cost much around The Knab?
Tell us what you run and where you are, whether that is out by Oystermouth, in The Knab centre, or anywhere across the SA postcode area. Both affect the price, which starts from £299.
Is the service on-site around The Knab?
Right across The Knab or the surrounding Swansea area, yes — your house or your work, whichever suits. Nothing is removed. Wherever the car happens to be standing is where the diesel particulate filter is treated.
When can you get to The Knab?
You will usually be given that same day or the next, according to what is already in the diary. What is free across the SA area is something we can tell you straight away — 0303 330 1830 is the number.
How long does mobile DPF regeneration take?
Two hours handles most jobs. Add to that where a second pass is required.
Do I actually need a DPF? Can I have it cut out instead?
You need it. A vehicle without a serviceable DPF fails its MOT and using it is illegal, so removal is not a fix and not something our engineers offer.
What happens if that warning light comes back?
The 30-day warranty covers follow-up, including a technician returning to The Knab.
After the work, how long will it last?
That turns on how the motor is run from then on. The M4 sits under 10 miles from The Knab, and Swansea is further still. Either journey is worth far rather more to the DPF than short hops around Limeslade. What fits your motor is something the engineer who attends goes over on the day.
