DPF fault help before the filter ruins the drive
If your diesel has a DPF warning light, limp mode, failed regeneration or repeated soot-load faults, the priority is to confirm why the filter is blocking before spending money. We scan the vehicle first, check the fault history, and explain the options clearly.
Send your registration and the warning message you see. We will confirm likely causes, price, and same-day mobile availability before you book.
DPF problems we commonly see
- DPF warning light: The car is asking for regeneration or has stored soot / ash load faults.
- Limp mode or poor power: Exhaust back-pressure, boost faults or sensor problems may be limiting performance.
- Failed regeneration: Common on cars used for short trips where the exhaust never gets hot enough.
- Expensive repair quote: We check the real cause before you commit to a costly filter, sensor or turbo-related repair.

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.
