Dry Hill, Somerset: Mobile DPF Cleaning
Sorting the DPF is done at the motor, not at a garage. An engineer comes at your door over in Dry Hill, clears the diesel particulate filter while it is still on the vehicle, runs a DPF regeneration, and you end up with the filter you arrived with.
You'll be given a price by phone before anyone goes, the clean beginning from £299, and the visit lasting typically around 2 hours.
Most owners find us with the light already on, and the car short of power. That is the position this page is meant for.
DPF light on? What to do
Not the unit, always. Main thing to get straight. A check goes before the work, because that same dash light has several candidate faults behind it.
How the motor is driven in the meantime makes a difference too.
- Amber light, car still driving as normal — a long constant run can even now shift it by itself. Costs nothing, and worth attempting before you ring anything.
- Motor already gone into limp mode — that window has gone. A drive will not touch it now.
- Diesel smell in the interior, or black smoke under the throttle — stop arranging long drives and get it looked at.
The motor has been telling you already
Last news, the light. The symptoms usually grow for a while before it shows:
- less power, above all pulling uphill
- you see the revs fall short of where they once went
- fuel economy getting worse
- silently, the stop/start bows out
- a diesel smell in the cabin, or smoke under acceleration
That is not evidence by itself. Alongside the light beside them, the filter is a fair guess.
What chokes diesel particulate filters around Dry Hill
Being a residential suburb, Dry Hill produces exactly the motoring a DPF handles the poorest. The school run to Portishead Primary School, West Hill at a crawl at the morning rush, ten minutes to Waitrose, the hop to Avonmouth — none of it lasts long enough or runs hot enough for the filter to finish a regeneration. What should burn off stays put.
Geography does not help either. The M5 is under 3 miles from Dry Hill and Bristol is under 10 miles away, so unless something carries you out that way regularly, whole weeks go by without the sustained run that could scour the filter by itself.
DPF regeneration, and the point limp mode ends it
The motor is defending itself, which is what limp mode means. A sustained drive works by starting a regeneration, and that is precisely what limp mode rules out: power capped, revs pinned, no regeneration available.
The usual advice — take it up the motorway — is sound, up until it is not. Beyond that line — limp mode — road work will not manage it, and the filter needs cleaning.
DPF cleaning at the vehicle across Dry Hill
Nothing comes off the motor. That catches out people. The DPF sits fixed where it is and the work goes on around it, on a driveway, in a works car park, anywhere it can sit for a couple of hours.
Nothing is cleaned until other faults are cleared. That means a scan first: live data off the ECU, soot load by percentage and by actual weight, and a check of the sensor readings, glow plugs and associated components.
Then the treatment. A cleaning fluid is injected through the access port on that motor and opens out inside the filter, lifting the soot and ash a regeneration alone will never budge. Sometimes a filter is blocked enough to need doing twice.
What the clean has lifted is then cleared by a regeneration. Ride along with the car and it becomes a monitored drive out of Dry Hill. Leave it and the regeneration goes statically, with real-time data verified once it is done.
Both read-outs are sent by email, so the figures from either end are kept. The second check is what proves the change, puts out the light and notes whatever is still open.
When a DPF clean is not the solution
A clean fixes one thing: a filter clogged with soot and ash. It does no good for:
- sensors, pressure or temperature, showing a restriction that is not real
- a stuck-open EGR valve
- a failure in the AdBlue system
- a regeneration that simply never starts, because of glow plugs or injectors
- the turbo putting oil into the filter
Which is why the diagnostic comes first. Proving to be one of them means learning it before any work starts, not after handing over for it.
A couple more worth noting. Leaving the filter cut out is not a solution — a vehicle without a serviceable DPF cannot pass its MOT and driving it is against the law. And cleaning is sometimes looked up as DPF renewal: nothing is exchanged, your existing filter is cleared in place and sent back into use.
The price of DPF cleaning in Dry Hill
Any visit takes a call-out charge — travelling to you, making the booking, doing the diagnostic and passing on the advice. The clean itself starts from £299.
The number is settled on the phone, once we are told the vehicle and what the filter is going to need. No flat rate could be truthful. Whereabouts you are matters as much as what you own: Dry Hill itself, Portishead next door, or further out within the BS postcode area.
Treatment that will not do it is not cleaning you pay for, and the scan is what says so. What still holds is the call-out charge, since the visit took place, the scan was run and the advice was offered.
If the light reappears inside that time, an engineer heads back out to Dry Hill — the work includes a 30-day warranty covering aftercare.
Great prompt service. Fixed my issue within the hour. Yes expensive at £458 but I was on the road and my van running again. Value for money.
Very professional, polite service. not cheap but worth every penny. I'm so happy with result strongly recommend. to use this service. after many disappointments with another companies. Thank you.
excellent service. Daniel kept us informed of what he was doing step by step. he was very knowledgeable and nothing was a trouble to him. would definitely recommend this service.
What we clean, and how far we travel round Dry Hill
The filter is treated on the vehicle on all of them: private cars, vans of any size and light commercials, HGVs, construction and plant machinery, agricultural vehicles. Nothing is taken anywhere.
Week in week out there is usually someone on West Hill, so Dry Hill hardly ever means a journey of its own, and Portishead, Woodhill and the villages past Clapton in Gordano follow. Further out across Somerset is even so worth phoning about — coverage runs UK-wide, and it is the diary rather than the distance that picks between today and tomorrow.

Things Dry Hill drivers ask about DPF cleaning
- Is a long drive enough alone?
- Sometimes, if you get it early and the vehicle has not slipped into limp mode. A sustained run at motorway speed is what it needs — not fifteen minutes or so to Waitrose and back.
- How long does the visit last?
- That is typically around 2 hours, though a badly loaded filter can require cleaning twice, which takes longer.
- Across Dry Hill, what does it cost?
- Starting from £299, with a charge for coming out that covers the scan and advice on what to do next. The vehicle and your address both move the number, so we price on the phone.
- Do I have to be around?
- The vehicle wants a space for two hours or so. Nobody expects you to be in it. The regeneration can be run as a monitored drive if you would sooner be there.
- Getting to Dry Hill — how soon?
- That depends on the schedule, but it is often same-day or next-day. Ask 0303 330 1830 what is open across the BS area.
- Is the filter taken off the motor?
- Cleaned where it is, on this service, so no. That job — a filter off, a filter back on — is not work we do.
- The light comes back — then what?
- Aftercare comes inside the 30-day warranty, and that includes an engineer returning to Dry Hill.
