Mobile DPF Cleaning across Tobermore and County Londonderry
Sorting the DPF takes place at the car, not at a garage. A fitter turns up at your address in Tobermore, treats the diesel particulate filter while it is attached to the motor, performs a DPF regeneration, and you keep the filter you started with.
You'll be given a number by phone before anyone goes, the clean starting from £299, and the visit lasting typically around 2 hours.
Most owners find us with the light showing, and the vehicle low on power. That is the situation this page is aimed at.
DPF light on? What comes next
Not the unit, automatically. Opening thing to get straight. Several faults put the same light on the very same dashboard, which is why a visit begins with a check rather than with cleaning.
Second thing: how you run it between now and then makes a difference.
- Amber light, car still driving normally — a long even run can still clear it by itself. Costs zero, and worth a try before you ring anything.
- Once the motor is in limp mode, motoring will not shift it. The window has closed.
- Diesel smell in the cabin, or black smoke under the throttle — stop arranging long drives and get it checked.
Signs the motor has been giving you
By the time the light shows, things have normally been slipping for some time. It is late news:
- climbing uphill, the power drops away
- an engine whose revs will not rise as they should
- fuel use that is worse than before
- the stop/start quietly bowing out
- diesel in the cabin, or smoke on the way up through the gears
None of that is proof alone. With the light, it is a fair guess the filter is blocked.
What blocks diesel particulate filters around Tobermore
For a DPF, the worst use is the type you get across a small village such as Tobermore. Run through a typical week: the local primary school and home, B842 at a crawl before nine, a five-minute run to the local shops, a hop to the nearest station. Nothing there goes on long enough or gets hot enough to complete a regeneration. Instead of burning away, the unburnt soot banks up.
Geography does not oblige either. The M77 is over 50 miles from Tobermore and Derry is under 50 miles away, so unless something carries you out that way often, whole weeks pass without the long steady run that would clear the filter by itself.
The point a DPF regeneration can no longer run
Limp mode is the car protecting itself. With power held down and the revs held, the regeneration the filter wants can never complete at all. That counts, because triggering one is just what a sustained run does.
Getting it up the motorway is the standard advice, and it stands right up to a limit. The far side of that stage — limp mode — road work will not be enough, and the filter wants treatment.
Where the vehicle stands is where the DPF is treated in Tobermore
Most owners do not expect this detail: the filter stays put. The job takes place with the DPF yet fixed to the car — on your drive, in a work car park, any place the motor can wait for a while.
Nothing is started until other faults are cleared. That involves a check first: real-time data off the ECU, soot load by percentage and by weight, and a review of the sensor readings, glow plugs and related parts.
Soot and ash that a regeneration alone will never move are loosened second, by a solution passed through the access port on that vehicle, which spreads inside the filter. Sometimes a filter is loaded enough to require doing twice.
A regeneration follows, driving off what the clean has freed. If you are there, that is carried out as a monitored drive out of Tobermore; if not, on the spot where the motor stands, with the real-time data verified once done.
Finally the diagnostic runs again — the change confirmed, the light put out, anything still open logged. Both read-outs arrive with you by email, so the numbers are on record.
Where treatment is not the fix
A filter choked with soot and ash is the one thing treatment answers. It will not reach:
- the wrong figure from a temperature sensor
- a jammed EGR valve
- an AdBlue system failure
- a regeneration that hardly ever completes, because of glow plugs or injectors
- turbo problems, with oil reaching the filter
The first diagnostic is there for just that. You are told before any work gets going, not after you have paid, where it turns out to be one of those.
DPF renewal is what people search for, but no part is swapped: the filter you own is treated where it sits and returned to use. Nor is having it cut out a fix, since the MOT then fails and driving becomes unlawful. Two more things worth noting.
The figure for DPF cleaning in Tobermore
A call-out charge stands whatever happens, and covers the visit, the booking fee, the scan and the advice given. Treatment itself opens from £299.
Not one flat rate would be straight, so the figure is fixed on the phone once we have the vehicle and what the filter is going to need. Where you are counts as much as what you drive: Tobermore itself, Maghera next door, or otherwise out across the BT postcode area.
Cleaning that will not work is not cleaning you pay for, and the scan is what says so. The call-out charge nonetheless holds, because the visit, the diagnostic and the advice have been done.
Aftercare is covered by a 30-day warranty: should the light come back within it, an engineer comes back to Tobermore.
I phoned at short notice and they managed to fit me in the same day. The fix has worked a treat.

Where we reach near Tobermore, and what we clean
One mobile service spans private cars, vans and light commercials, heavy goods vehicles, construction and plant machinery and agricultural vehicles, and on every one the filter is treated where it sits rather than taken anywhere.
Engineers are along B842 nearly every week, so Tobermore is rarely a journey of its own, and the same run picks up Maghera, Desertmartin and the spots out past Magherafelt. It is the calendar, not the distance, that picks whether it is this day or the next, and coverage runs UK-wide — so call anyway from further out through County Londonderry.

Questions Tobermore drivers ask about DPF cleaning
- Is a long drive enough on its own?
- If you get it early enough, and the car is not in limp mode, sometimes. It takes a long run at motorway speed, not five minutes flat to the local shops and back.
- How long does the visit last?
- Expect typically around 2 hours — badly loaded filters sometimes take a second pass, which lengthens it.
- Around Tobermore, what does it run to?
- The call-out charge pays for the visit, the check and the advice; cleaning itself begins from £299. The vehicle and your address both shift the number, so we settle it on the phone.
- Is it essential for me to be present?
- A spot for the car to stand, for a couple of hours, is all that is needed. Not you. The regeneration can be run as a watched drive if you would prefer to ride along.
- When can someone come to Tobermore?
- That hangs on the schedule, but it is often same-day or next-day. Ask 0303 330 1830 what is open across the BT area.
- Will the filter be taken off?
- Cleaned where it sits, on this service, so no. We will not take filters off or put them back on, in either direction.
- Suppose the light comes back?
- Taken in by the 30-day warranty: aftercare, and an engineer coming back to Tobermore.
