Rosemary Lane, Devon: Mobile DPF Cleaning
With call-out DPF cleaning, we travel to the vehicle. The engineer pulls up at your place over in Rosemary Lane and sets up. The diesel particulate filter is cleaned still on the car, a DPF regeneration comes next, and you hold on to the filter you came with.
Allow for the visit lasting typically around 2 hours. The clean starts from £299, settled on the phone before anyone sets off.
If the light is showing and the car is down on power, this page is the right one. That is how most people get to us.
The DPF light is on. What now?
First thing: it is not always the unit. Cleaning is not where a visit starts. A scan is — plenty of faults register as the same signal.
How the car is driven in the meantime counts too.
- Worth a go before you ring anything: amber light, motor driving fine, just one steady run, no outlay.
- A drive will not reach it now — limp mode means that window has now closed.
- Stop planning long drives and get it checked if the cabin reeks of diesel or there is black smoke when you press on.
Signs the motor has been sending you
The light is belated news. By the time it appears, the symptoms have normally been mounting for a while:
- pulling uphill, the power tails off
- the revs no longer climb the way they used to
- the fuel consumption is poorer
- a stop/start that has meekly packed in
- diesel in the car, or smoke on the way up through the gears
Any one of those, taken singly, is not proof. Next to the light alongside them, the filter is a fair guess.
Choked diesel particulate filters near Rosemary Lane, and the cause
Being a rural hamlet, Rosemary Lane generates precisely the use a DPF copes with worst. The school run to Hemyock Primary School, Gray's Lane at a halt at half eight, ten minutes to Waitrose, the run to Tiverton Parkway — nothing of it goes on long enough or is hot enough for the filter to see through a regeneration. What should burn off stays behind.
The M5 stands under 3 miles from Rosemary Lane, Exeter under 25 miles off, and unless something pulls you out that way often, entire weeks go by without the long unbroken run that empties a unit. Geography does not assist.
Limp mode, and when DPF regeneration stops
Limp mode is the vehicle defending itself. Pulling power is held down, the revs will not climb, and the regeneration the filter needs can not happen — which is the entire problem, because a proper drive works by setting off that regeneration.
So the common advice to run it up the motorway is sensible advice, up until it is not. Past that line — limp mode — road work will not be enough, and the filter wants cleaning.
DPF cleaning at the vehicle in Rosemary Lane
The filter does not come off. That is the bit most people do not expect: the job is done with the DPF still bolted to the motor, on your drive, in a work car park, wherever the car can stand for a couple of hours.
The ECU is taken first, reporting soot load by proportion and by actual weight, along with a review of sensor readings, glow plugs and connected components, so nothing is started while another fault is still in play.
A cleaning fluid then is fed in through the access point on that car, expanding inside the filter to lift soot and ash a regeneration by itself will never budge. Where the filter is severely blocked, allow for a second pass.
Then a regeneration, to burn off what the clean has freed. Come with the motor and it becomes a monitored drive out of Rosemary Lane. Drop it and the regeneration goes on the spot, with real-time data read once it is done.
A second diagnostic proves the change, clears the warning light and lists anything still open. Both read-outs are emailed over, so you end up with the before and after figures on record.
The failures a DPF clean cannot fix
Only one fault is answered by cleaning: the filter choked with ash and soot. It does no good for:
- a pressure or temperature sensor flagging a blockage that is not there
- an EGR valve jammed open
- AdBlue system faults
- injectors or glow plugs that block a regeneration completing at all
- the turbo pushing oil into the filter
That is what the first diagnostic is for. When it turns out to be one of those, you are warned before any work begins rather than after you have paid anything.
Hollowing the filter out is not a solution: without a working DPF a vehicle fails its MOT, and driving it is against the law. DPF renewal is the wording people search for, though nothing is replaced — your own filter is cleaned in place and returned into use. Two more worth knowing.
What DPF cleaning comes to around Rosemary Lane
The treatment starts from £299. A call-out charge covers every visit, and covers the call-out itself, the booking, the diagnostic and the advice that follows.
Once we know what you drive, and roughly what the filter will need, the figure gets agreed over phone. A single price for every job would not be straight. What you own and where you are both change it: Rosemary Lane itself, over at Clayhidon, or farther out within the EX postcode area.
Treatment that will not work is not treatment you pay for, and the check is what says so. You still pay that charge: someone travelled, ran the scan and gave you the advice.
If the light returns inside that period, an engineer travels back out to Rosemary Lane — the clean carries a 30-day warranty taking in aftercare.
Daz was fantastic. Sussed out the problem with my cars engine. Was professional and genuine, my car didn't have a blocked DPD so no clean needed. Excellent service.
Dan was fabulous and courteous. He did mention before the clean that the DPF was nearly empty and it was up to me still go ahead with the clean. The clean was performed and the number did improve. Great advice and prompt service. Highly recommended.
Excellent service, good lad and very helpful and very pleasant too. Very good rates, in fact a lot cheaper than taking it locally and these come out to you.
What we clean, and how far we go round Rosemary Lane
Cars and estates, panel vans and light commercials, heavy goods vehicles, plant and construction machinery, farm vehicles — the one mobile service across all of them, and on all of them the filter is treated where it sits rather than moved anywhere.
Most weeks there is already someone on Gray's Lane, so Rosemary Lane rarely means a journey of its own, and Clayhidon, Millhayes and the spots past Hemyock are on the way. Further out through Devon is nonetheless worth phoning about — coverage runs UK-wide, and it is the diary rather than the distance that picks between today and tomorrow.

Questions Rosemary Lane drivers ask about DPF cleaning
- Is a long drive enough on its own?
- Early enough, and with the car out of limp mode, yes — sometimes. That requires motorway speed for a sustained stretch, rather than a short trip to Waitrose.
- Does the visit take long?
- That is typically around 2 hours, though a badly loaded filter can need cleaning twice, which takes longer.
- Cost across Rosemary Lane — what is it?
- The call-out charge covers the visit, the scan and the advice; cleaning itself begins from £299. Settling it is done by phone, since what you own and where you are both change the figure.
- Is it necessary for me to be there?
- Space for the car to wait, for a couple of hours, is all that is needed. Not you. Wanting to be there is no problem: the regeneration then is done out on the road, monitored.
- When can someone get to Rosemary Lane?
- It is often same-day or next-day, depending on what is currently in the diary. Ring 0303 330 1830 and you will learn what is free across the EX area.
- Is the filter removed from the car?
- It is cleaned where it stands, on the call-out service. That work — a filter off, a filter back on — is not work we do.
- Suppose the light reappears?
- Included by the 30-day warranty: aftercare, and an engineer heading back to Rosemary Lane.
