A blocked or failing diesel particulate filter is one of the most expensive problems a modern diesel can have. For off-road and export vehicles we remove the DPF/FAP in software so the ECU stops trying to regenerate a filter that isn't working.
End the regeneration cycle
Constant regens waste fuel, dump heat into the exhaust and eventually block the filter solid. Removing it in software stops the cycle for good.
Restore performance & MPG
A clogged DPF chokes the engine. With it removed you get smoother acceleration, lower exhaust gas temperatures and better fuel economy.
Cheaper than replacement
A replacement DPF can cost £2,000 or more, and forced regens and repairs add up fast. A software solution is a fraction of that.
Done properly in the ECU
We map out the DPF functions cleanly so there are no warning lights or limp mode — not just a sensor cheat. Pipe options available where needed.

Good to know
Common questions.
Is DPF removal legal?+
It is for vehicles used off-road, on private land, for motorsport or for export only. A vehicle with an obviously removed DPF will fail its MOT and it's an offence to use it on the road — this service is sold on that basis.
What causes a DPF to fail?+
Lots of short journeys that never get hot enough to regen, a faulty sensor or EGR, low-quality fuel or oil, a tuning fault, or simply age and mileage. We'll diagnose the cause before recommending anything.
Will I get warning lights afterwards?+
No — done in software the DPF functions are removed cleanly, so there's no DPF light, no limp mode and no stored regeneration faults.
Do you do a pipe as well as software?+
For many vehicles a decat/DPF-delete pipe is available alongside the software. Ask us about your specific vehicle.
