Mobile DPF Cleaning in Tunworth and Hampshire
The car sits put — on-site DPF cleaning goes to it. A fitter turns up at your place across Tunworth, clears the diesel particulate filter while it is attached to the vehicle, performs a DPF regeneration, and you end up with the filter you started with.
The visit lasts typically around 2 hours, the clean opens from £299, and the price is fixed over the phone before anyone leaves.
The light is showing and the motor is down on power — that is how we generally come across people, and roughly what this page is about.
DPF light on? What happens next
The unit is not always what is to blame, and that leads. Treatment is not where a visit opens. A check is — a number of faults show up as the same light.
Second thing: how you handle it between now and then makes a difference.
- Amber light, vehicle still driving as normal — a long steady run can still shift it alone. Costs nothing, and worth trying before you ring anything.
- A drive will not shift it now — limp mode means that window has already shut.
- Diesel smell in the car, or black smoke under hard acceleration — stop planning long drives and get it looked at.
Before the light, what the car was showing you
By the time the light shows, things have normally been slipping for a while. It is belated news:
- going uphill, the power tails off
- an engine whose revs will not pull as before
- fuel use that is worse than it used to be
- the stop/start silently bowing out
- a diesel smell in the interior, or smoke under hard acceleration
Any one of those, taken by itself, is not evidence. Alongside the light alongside them, the filter is a fair assumption.
What clogs diesel particulate filters round Tunworth
Tunworth is a rural hamlet, and the motoring that goes with one is the worst sort for a DPF. Think about an ordinary week: Rucstall Primary School and home, Hackwood Lane at a crawl before half nine, a short hop to Co-op Food, a dash to Basingstoke. Nothing there runs long enough or runs hot enough to complete a regeneration. The soot load builds up rather than burning away.
The M3 stands under 3 miles from Tunworth, Winchester under 25 miles off, and unless something takes you out that way regularly, whole weeks go by without the sustained run that empties a unit. Geography does not help.
Why limp mode stops a DPF regeneration
The car is looking after itself, which is what limp mode means. With power held down and the revs pinned, the regeneration the filter needs cannot run at all. That counts, because triggering one is just what a motorway run does.
The common advice — take it up the motorway — is sound, until it is not. Beyond that stage — limp mode — more driving will not manage it, and the filter requires a clean.
Mobile DPF cleaning where the vehicle stands across Tunworth
On your driveway, in a work car park, wherever the motor can wait for a while: the job is done with the filter still fixed on, which is the part most owners do not anticipate.
The ECU is interrogated first, giving soot load by percent and by mass, along with a check of sensor feeds, glow plugs and related hardware, so nothing is started while another fault is still in play.
Then the clean. A cleaning fluid is injected through the entry point on that motor and expands inside the filter, loosening the soot and ash a regeneration alone will never move. Sometimes a filter is blocked enough to take doing twice.
What the clean has loosened is then burned off by a regeneration. Either it is done as a monitored drive out of Tunworth, with you along, or it runs where the vehicle sits and the running data is checked after.
Then a second scan, confirming the change, putting out the warning light and listing anything still showing. Both sets of figures are sent over, so the before and after figures are recorded.
What a DPF clean will not touch
One thing is what cleaning answers — a filter blocked with soot and ash. It does nothing for:
- pressure sensors flagging a blockage that is not there
- an EGR valve jammed open
- AdBlue system faults
- injectors or glow plugs that prevent a regeneration starting whatsoever
- turbo trouble, with oil reaching the filter
The first diagnostic is there for just that. Transpiring to be one of them means finding out it before any work gets going, not after paying anything.
A couple more worth noting. Having the filter hollowed out is not a fix — a vehicle without a working 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 existing filter is cleaned in place and returned into use.
Prices for DPF cleaning around Tunworth
Cleaning opens from £299, with the call-out charge on top of that for every visit — it pays for the call-out, the booking, the diagnostics and the advice.
The price is fixed on the phone, once we are told the vehicle and what the filter is apt to need. No flat rate could be truthful. What you drive and where you are both change it: Tunworth itself, over at Upton Grey, or otherwise out in the RG postcode area.
If the scan rules a clean out, there is nothing to pay for it. You nonetheless pay that charge: someone turned up, did the check and offered you the advice.
Aftercare is covered by a 30-day warranty: should the light return within it, an engineer heads back to Tunworth.
Recently had the DPF cleaned by Liam. Good communication throughout, and he clearly answered all questions. The van is now up and running nicely.
Absolutely spot on service, Chris travelled all the way from Wrexham to Lytham St Anne's. Spent a few hours on my car, no issues since. Service from the booking office easy and hassle free and friendly. Can't recommend them enough.
Had a clean. Didn't fix problem. Came back out. Still didn't fix the problem. Wast of time and £400.
What we clean, and how far we travel round Tunworth
Cars, vans and light commercials, HGVs and lorries, plant machinery, farm vehicles — one mobile service across all of them, and on all of them the filter is cleaned on the vehicle rather than taken anywhere.
Our engineers are along Hackwood Lane nearly every week, so Tunworth is hardly ever a journey of its own, and the same run picks up Upton Grey, Winslade and the places out past Little Hoddington. Coverage is UK-wide, so farther out across Hampshire is nonetheless worth a call, and what decides between today and tomorrow is the schedule rather than the distance.

What Tunworth drivers want to know about DPF cleaning
- Will a long drive shift it?
- Sometimes, if you spot it early enough and the car has not dropped into limp mode. That calls for motorway speed for a steady run, rather than a short trip to Co-op Food.
- The visit lasts how long?
- Bank on typically around 2 hours, with a second clean lengthening that where the filter is heavily loaded.
- What does it come to in Tunworth?
- Starting from £299, with a charge for travelling that covers the diagnostic and advice on what to do next. Both the vehicle and where you are change it, which is why pricing is done by phone.
- Is it essential for me to be around?
- The vehicle needs a place for two hours or so. Nobody expects you to be in it. If you would rather come along, the regeneration can be run as a monitored drive instead.
- When can someone travel to Tunworth?
- You are offered often same-day or next-day, though it depends what is already in the schedule. One phone call to 0303 330 1830 and you will know what the RG area has open.
- Does the filter leave the vehicle?
- On the mobile service, no: the filter is treated in place. We do not take filters off or fit them back on, in either direction.
- The light returns — then what?
- The 30-day warranty covers aftercare, including an engineer coming back to Tunworth.
