DPF Delete
Removal of the Diesel Particulate Filter function to restore performance.
DPF Delete (Diesel Particulate Filter Delete)
The DPF is a filter fitted in the exhaust of diesel vehicles to trap soot and reduce emissions. Over time, it gets clogged, especially in vehicles mainly used for short journeys. A blocked DPF causes:
- Reduced engine power
- Poor fuel economy
- Warning lights
- Expensive repairs or regeneration
Our Service
We electronically remove the DPF function from the ECU, so the vehicle no longer attempts to regenerate or monitor the filter. This prevents limp mode and restores performance.

Frequently Asked Questions
A missing DPF where one was fitted as standard will result in an MOT failure. This modification is for off-road use only.
Yes, for a complete solution, the internal filter usually needs to be removed or the pipe replaced, alongside our software solution.
The software side of a DPF delete typically takes 1-3 hours. If physical removal of the filter element is also required, additional time may be needed depending on the vehicle.
Removing the DPF function can restore lost engine power, improve throttle response, reduce exhaust back-pressure, and improve fuel economy — especially on vehicles that have been struggling with repeated regeneration cycles.
No. Our software solution disables all DPF-related monitoring in the ECU, so no warning lights, fault codes, or limp mode will be triggered after the procedure.
Most diesel vehicles from 2007 onwards fitted with a DPF can have the software disabled. This includes cars, vans, and commercial vehicles from manufacturers like BMW, Mercedes, VW, Audi, Ford, Vauxhall, Land Rover, and many more.
Yes. We always save a full backup of the original ECU software before making any modifications. The factory DPF function can be restored at any time.
Yes, DPF delete is often combined with a Stage 1 or Stage 2 remap for maximum performance gains. We can carry out both services in a single visit.
