Mobile DPF Cleaning around Newnham and Hampshire
Sorting the DPF takes place at the car, not at a garage. The technician turns up at your place in Newnham and sets up. The diesel particulate filter is cleaned still on the car, a DPF regeneration runs after it, and you keep the filter you started with.
You'll have a price by phone before anyone departs, the clean beginning from £299, and the visit taking typically around 2 hours.
Most owners find us with the light showing, and the motor down on power. That is exactly what this page is meant for.
The DPF light is on. What then?
First thing: it is not always the filter. A clean is not where a visit starts. A diagnostic is — several faults show up as the same signal.
Second thing: how you drive it between now and then counts.
- Amber light, car still driving as normal — a long even run can yet sort it on its own. Costs nothing at all, and worth attempting before you book anything.
- Motor already dropped into limp mode — that window has closed. A drive will not touch it now.
- Get it looked at rather than running it — diesel in the car, or smoke on hard acceleration, has gone well past the long-run stage.
Signs the car has been giving you
Symptoms have usually been building for weeks before the light so much as appears. Late news, in other words:
- less power, especially going uphill
- an engine whose revs will not climb like they did
- the fuel consumption is poorer
- silently, the stop/start gives up
- a diesel smell in the cabin, or smoke under hard acceleration
None of that is proof alone. The light alongside them points at a loaded filter.
Blocked diesel particulate filters round Newnham, and the cause
For a DPF, the poorest use is the kind you meet around a rural village such as Newnham. None of it lasts long enough or gets hot enough for the filter to complete a regeneration: the school run to Hook Infant School, Ridge Lane barely moving at half past eight, ten minutes to Tesco, the dash to Hook. What should burn away stays put.
Except when you have a routine reason to get out to the M3, under a mile from Newnham, or out to Winchester under 25 miles away, weeks slip past without a long unbroken drive. Geography is no help.
Why limp mode prevents a DPF regeneration
What limp mode means is the car defending itself. Power is capped, the revs will not rise, and the regeneration the filter requires can no longer happen — which is the real catch, because a long drive works by starting that regeneration.
So the standard advice to run it up the motorway is sound advice, right until it is not. The filter needs treatment rather than road work once the motor has gone into limp mode.
Where the car stands is where the DPF is cleaned across Newnham
Most owners do not anticipate this part: the filter stays on. The job is done with the DPF even now bolted to the vehicle — on your front, in a work car park, anywhere the vehicle can stand for a couple of hours.
First a diagnostic. Real-time ECU data, the soot load as a percent and as a weight, the sensor readings, the glow plugs, the associated components — all of it logged before anything is touched.
Then the treatment. A cleaning solution goes in through the access port on that motor and expands inside the filter, loosening the soot and ash a regeneration by itself will never budge. Severely clogged filters sometimes need a second pass.
Then a regeneration, to burn off what the clean has loosened. If you are there, that is carried out as a monitored drive out of Newnham; if not, in place where the motor waits, with the running data checked afterwards.
Both sets of figures go over by email, so the figures from either end are recorded. The second scan is what verifies the change, resets the light and lists whatever is still outstanding.
Where a clean is not the fix
One thing is what treatment cures — a filter clogged with soot and ash. It does little for:
- the wrong reading from a pressure or temperature sensor
- the EGR valve held open
- a failure in the AdBlue system
- a regeneration that hardly ever runs, because of glow plugs or injectors
- turbo failure, with oil getting into the filter
Which is why the scan happens first. When it proves to be one of those, you are warned before any work starts rather than after you have handed over for it.
Two more worth bearing in mind. Leaving the filter hollowed out is not a remedy — a vehicle without a functioning DPF fails its MOT and driving it is illegal. And cleaning is sometimes looked up as DPF renewal: nothing is swapped, your own filter is treated in place and put back into use.
DPF cleaning costs in Newnham
The cleaning opens from £299. A call-out charge covers every visit, and takes in the call-out itself, the booking, the scan and the advice that follows.
The price is settled on the phone, once we know the vehicle and what the filter is likely to need. No flat rate could be honest. What you drive and where you are both shift it: Newnham itself, across at Heather Row, or farther out across the RG postcode area.
If the scan rules treatment out, there is not a penny to pay for it. You still pay that charge: someone came out, did the check and offered you the advice.
The work includes a 30-day warranty covering aftercare, including an engineer coming back out to Newnham if the light returns inside that window.
The engineer called Daz was excellent he was very friendly and personable and very knowledgeable about his work. My car is great again now.
Great service, very quick response. Excellent attention to detail and very clear explanation of the issues affecting my DPF. Highly recommended.

What we clean, and how far we reach near Newnham
A single on-site service covers cars and estates, vans of any size and light commercials, heavy goods vehicles, plant machinery and agricultural vehicles, and on every one the filter is cleaned on the vehicle rather than moved anywhere.
Engineers are along Ridge Lane week in week out, so Newnham is seldom a special trip, and the same run covers Heather Row, Up Nately and the villages out past Nately Scures. Even further out through Hampshire is even so worth phoning about — coverage runs UK-wide, and it is the calendar rather than the distance that settles between this day and the next.

Questions Newnham drivers ask about DPF cleaning
- Does a long run shift it?
- Sometimes, if you catch it early and the motor has not slipped into limp mode. That means motorway speed for a sustained spell, rather than a quick trip to Tesco.
- The visit lasts how long?
- Bank on typically around 2 hours, with a second clean extending that where the filter is severely clogged.
- The cost in Newnham — what is it?
- Treatment starts from £299, and the call-out charge on top pays for the visit, the diagnostic and the advice. Both the vehicle and where you are shift it, which is why quoting goes by phone.
- Have I need to be present?
- No. The vehicle needs somewhere to wait for a couple of hours; you need not stand with it. Travel along if you would rather, and the regeneration turns into a supervised drive.
- How soon can someone travel to Newnham?
- Depending on the calendar, often same-day or next-day is usual. Phone 0303 330 1830 and you will hear what is free across the RG area.
- Is the filter removed from the vehicle?
- Not on the call-out service — it is cleaned where it stands. That job — a filter off, a filter back on — is not a job we do.
- The light returns — then what?
- Aftercare sits inside the 30-day warranty, and that includes an engineer heading back to Newnham.
