DPF Off - Diesel Particulate Filter Deactivation
Software deactivation of the DPF system to end clogging, regeneration and limp-mode problems.
The DPF (Diesel Particulate Filter) sits in the diesel exhaust and traps soot, then periodically burns it off in a process called regeneration. It is an emissions device, and when it works as intended it keeps particulate output low.
The trouble appears with age and short-trip use: the filter clogs, power drops, fuel consumption rises, and the car regenerates constantly or drops into limp mode. Repeated regeneration can also dilute the engine oil with fuel, and a replacement filter is expensive.
DPF Off deactivates every DPF-related function in the ECU, including the differential-pressure and temperature sensor readings, the regeneration cycles and the related fault codes. It is applied together with physical removal or gutting of the filter, and the software then lets the ECU run cleanly without it.
With the system deactivated the engine breathes more freely, the regeneration cycle and DPF fault codes stop, and a costly filter replacement is avoided. Because this removes an emission-control device, DPF Off is intended for off-road, motorsport or export use, and disabling such equipment may not be legal for road use in many countries, so the owner is responsible for checking local regulations.

Frequently Asked Questions
What does DPF Off do?
It removes the diesel particulate filter logic from the ECU: regeneration cycles, differential pressure monitoring and the related fault codes and limp mode are disabled so the ECU no longer expects a filter.
Who is DPF Off for?
Workshops dealing with clogged or failed filters, repeated regenerations or limp mode, and off-road, agricultural or motorsport vehicles. The filter must also be physically removed or gutted; software alone is not enough.
Which file do I need to upload?
A full read of the original ECU file. If the car has a combined request (DPF plus EGR, AdBlue or Stage 1) upload once and select all options.
How long does DPF Off take?
Typically 10-45 minutes if the file is not already in the database; database hits are ready in minutes.
Is DPF Off reversible?
Yes. The original file is kept and can be flashed back when the filter is refitted.
Is DPF Off legal for road use?
Removing emission equipment is not permitted on public roads in most countries, including the EU, UK and Turkey, and can affect inspection, insurance and warranty. The service is provided for off-road, motorsport and export use; the workshop is responsible for compliance.
