The DPF stays on the vehicle. We clean it with a three-stage chemical flush, run a controlled forced regeneration and show you the back-pressure readings before and after, all at our Fenton workshop.

How it works
Bring the vehicle to our Fenton workshop and the filter stays where it is. Because nothing is unbolted, there’s no risk of snapped studs or damaged sensors, and no extra labour for removing and refitting the DPF.
We start by scanning the live soot and back-pressure data, so we know it’s the filter that’s blocked rather than a sensor. A three-stage chemical flush then breaks down the soot and ash inside, and a controlled forced regeneration burns off what’s been loosened.
Most on-car cleans take 60–90 minutes, but we’ll give you a time when you book, and you’re welcome to wait while it’s done. You see the readings before and after, so you know the clean has worked, not just that the warning light has been cleared.

A recent on-car clean
Both came in with serious DPF problems and were stuck in restricted mode. We carried out our on-vehicle DPF clean on each one and brought the backpressure back down to normal, below 6 mbar, so both drove away out of restricted mode.
Why it matters
A blocked filter traps exhaust gas, so back-pressure rises, the turbo works harder and exhaust temperatures climb. The ECU then cuts power to protect the engine, and you end up in limp mode.
Cleaning the filter brings the back-pressure back down. The engine can breathe again, regenerations can finish on their own and the warning light stays off. A clear filter also keeps smoke readings under the MOT limit.
On-car cleaning starts from £200, which is usually much less than a replacement filter. Prices shown are starting prices. The final price depends on many factors, including the vehicle and how complex the job is, and we confirm it before any work starts. See our DPF cleaning cost guide.
If the filter is cracked, melted or too packed with ash for an on-car clean, we’ll tell you before we start and talk you through off-car cleaning or a replacement.
Vehicles
We can clean almost any diesel with a DPF, but these models come into the workshop week after week.
Stop-start courier runs overload the filter, and the van drops into limp mode with a P2463 soot code.
Short commutes stop regenerations finishing, back-pressure climbs and the DPF light comes on.
Ash builds up in the filter, bringing up a drivetrain fault message and reduced boost.
Town idling loads soot quickly, and the ECU limits revs once the filter is full.
Long spells of idling keep the exhaust too cool to regenerate, until a P2002 efficiency code appears.
School runs and short trips block the filter again and again, and forced regens fail.

How much does an on-car DPF clean cost?
On-car DPF cleaning starts from £200. That covers the scan, the three-stage chemical flush, the forced regeneration and the before-and-after readings. Prices shown are starting prices. The final price depends on many factors, including the vehicle and how complex the job is, and we confirm it before any work starts.
How long does it take?
Most on-car cleans take 60–90 minutes, but we’ll give you a time when you book. You’re welcome to wait while it’s done, and same-day appointments are often available if we have space.
Does the DPF stay on the car?
Yes. We clean the filter in place, so there’s no risk of snapped studs or damaged sensors from removing it.
What if the filter is cracked or melted?
We check for damage before cleaning. If the filter is beyond saving, we’ll tell you and talk you through replacement options before going any further.
Do you reset the ECU after the clean?
Yes. We clear the fault codes and reset the soot and ash counters and adaptation values, so the ECU starts fresh.
Do you offer mobile DPF cleaning?
No, we no longer offer a mobile service. Every clean is done at our Fenton workshop in Stoke-on-Trent, where we can diagnose the fault and check the readings properly before and after. If you can’t get to us, you can post your DPF instead.
Call or WhatsApp us with the reg and what the car is doing. Same-day slots are often available, space permitting.
