Hardwick, Northamptonshire: Mobile DPF Cleaning
On-site DPF cleaning comes to the car. No body shop, no filter going anywhere. An engineer travels to your address in Hardwick, clears the diesel particulate filter in place, runs a DPF regeneration, and you end up with the filter you arrived with.
The visit runs typically around 2 hours, the clean opens from £299, and the number is settled on the phone before anyone sets off.
Most people find us with the light showing, and the car short of power. That is the position this page is written for.
DPF light on? What comes next
It might not be the DPF at all. That is the opening thing. A diagnostic comes before any cleaning, because that same dash light has a number of likely faults behind it.
The use you manage in the meantime tells. That is the other thing.
- A long even run may still manage it, provided the light is amber and the vehicle runs fine. Costs zero, so have a go at that before booking.
- Car already dropped into limp mode — that window has shut. A drive will not touch it now.
- A diesel smell inside, or black smoke under hard acceleration, is the point to stop arranging long drives and call.
Before the light, what the vehicle was warning you
Symptoms have generally been building for weeks before the light ever shows. Late news, in other words:
- power tailing off, particularly going uphill
- you see the revs never reach where they used to go
- fuel consumption getting worse
- a stop/start that has quietly given up
- smoke under acceleration, or a diesel smell inside
None of that is evidence alone. It is a fair bet the filter is loaded once the light is on as well.
Why diesel particulate filters choke around Hardwick
The day-to-day driving that comes with a rural village like Hardwick is the worst kind for a DPF. None of it runs long enough or runs hot enough for the filter to finish a regeneration: the school run to The Glenvale Church of England Primary School, Manor Farm Close barely moving at half eight, five minutes to Co-op Food, the dash to Wellingborough. The soot load banks up rather than burning off.
The M1 sits under 15 miles from Hardwick, Milton Keynes under 25 miles off, and unless something carries you out that way regularly, entire weeks pass without the long steady run that clears a unit. Geography does not oblige.
DPF regeneration, and the moment limp mode stops it
What limp mode amounts to is the vehicle defending itself. The whole problem is that a long drive works by starting a regeneration, and in limp mode the revs will not pull and power is capped.
Getting it up the motorway is the standard advice, and it stands right up to a limit. Once the vehicle is in limp mode you are the far side of that point, and the filter requires treatment rather than driving.
The motor stays where it is for call-out DPF cleaning in Hardwick
Most drivers do not expect this detail: the filter stays put. The job takes place with the DPF even now bolted to the motor — on your front, in a work car park, anywhere the car can stand for a while.
The ECU is interrogated first, giving soot load by proportion and by weight, along with a look over of sensor readings, glow plugs and associated parts, so nothing is touched while another fault is still in play.
Then comes the clean itself: a cleaning solution in through the vehicle's own entry point, opening out inside the filter and loosening what a regeneration never can. Where the filter is severely blocked, allow for a second pass.
A regeneration comes next, clearing what the clean has freed. That is a monitored drive out of Hardwick if you are there, or a static regeneration where the car sits, with the real-time data checked afterwards.
Finally the diagnostic runs again — the change proven, the light cleared, anything still showing written down. Both reports reach you by email, so the numbers are on record.
What a DPF clean will not touch
A filter choked with soot and ash is the one thing cleaning cures. It will not help:
- a pressure sensor reporting a restriction that is not there
- the EGR valve held open
- a problem in the AdBlue system
- a regeneration that simply never runs, because of glow plugs or injectors
- the turbo pushing oil into the filter
That is what the first check is for. You are warned before the work starts, not after you have handed over, where it turns out to be one of those.
Two more worth noting. Leaving the filter hollowed out is not a remedy — a vehicle without a functioning DPF fails its MOT and driving it is an offence. And cleaning is sometimes described as DPF renewal: nothing is exchanged, your original filter is cleared in place and returned into use.
The price of DPF cleaning around Hardwick
A clean starts from £299, with the call-out charge on top of that for every visit — it takes in the call-out, the booking, the scans and the advice.
Once we know what you run, and about what the filter will take, the price gets settled by phone. A single price for all would not be straight. What you drive and where you are both shift it: Hardwick itself, out at Great Harrowden, or further out in the NN postcode area.
You are not asked to pay for cleaning that the diagnostic says will not work. What nonetheless stands is the call-out charge, since the visit took place, the check was carried out and the advice was offered.
Aftercare is taken in by a 30-day warranty: should the light return within it, an engineer heads back to Hardwick.
Fantastic service from Andras and his trainee assistant (Andy?) sorry the name has slipped my brain. Andras was very knowledgeable and he got my van running within good time. I'm very happy with the service I was given! Thank you.
Very happy with the service. Liam arrived at agreed time and was very professional. He explain the process and answered all the questions I had.
I have done second time done the DPF cleaning process and the engineers were always polite, informative, and professional. I will use this service again if need. Thanks!
Where we get to round Hardwick, and what we clean
Whatever it is — car, light van, light commercial, heavy goods vehicle, plant, construction machinery, farm vehicle — the one on-site service stands, and the filter never quits it.
Nearly every week there is already someone on Manor Farm Close, so Hardwick rarely means a detour, and Great Harrowden, Hatton Park and the villages past Little Harrowden come with it. Even further out around Northamptonshire is still worth phoning about — coverage is UK-wide, and it is the schedule rather than the distance that decides between this day and the next.

Things Hardwick drivers ask about DPF cleaning
- Does a long run clear it?
- It can, provided you spot it in time and limp mode has not begun. Five minutes to Co-op Food and back will not do it; motorway speed, held for some time, will.
- The visit runs how long?
- It is typically around 2 hours. A heavily loaded filter can take a second clean, which lengthens that.
- What does it come to across Hardwick?
- Beginning from £299, with a charge for coming out that takes in the scan and advice on what to do next. The vehicle and your address both change the number, so we price on the phone.
- Is it necessary for me to be there?
- No. The motor needs space to sit for a couple of hours; you need not stand with it. Preferring to be there is fine: the regeneration then goes out on the road, monitored.
- When can someone come to Hardwick?
- That hangs on the calendar, but it is often same-day or next-day. Phone 0303 330 1830 what is available across the NN area.
- Does the filter leave the motor?
- Cleaned where it sits, on this service, so no. We do not take filters off or bolt them back on, either way.
- The light returns — then what?
- Aftercare sits inside the 30-day warranty, and that includes an engineer heading back to Hardwick.
