Petrol Emissions Solutions
DIAGNOSE · ADVISE · RESOLVE
Software solutions for petrol emissions faults — secondary lambda/O2 sensor issues and blocked GPF (petrol particulate filter) problems. Supplied strictly for off-road, motorsport or export vehicles. Please read the legal notice below before enquiring. (Petrol engines only — not suitable for diesels.)
Important legal notice — please read
In the UK, Europe and most other countries it’s illegal to use a vehicle on public roads if its factory emissions-control equipment has been removed, disabled or bypassed. Doing so will cause an automatic MOT failure and can invalidate your insurance.
For that reason, all this work is supplied strictly for off-road use, motorsport applications or vehicles being exported. If you’re unsure whether your vehicle qualifies, please ask before booking.
What these systems do
Petrol cars run their own emissions systems, and when they fault they can bring on warning lights, restriction or limp mode. Here’s what each one does and the software solution available for off-road or export vehicles:
Lambda / O2 (secondary sensor)
The secondary oxygen sensor monitors the catalytic converter’s efficiency. When a cat has been removed or is faulty, it commonly triggers a P0420 fault and the engine management light. The software solution reconfigures the ECU so the secondary sensor readings no longer trigger those faults.
GPF — Gasoline Particulate Filter
The GPF is the petrol equivalent of a diesel’s DPF — it traps soot from direct-injection petrol engines. When it blocks it can cause restriction, warning lights and limp mode. The software solution stops the regeneration cycles and the sensor monitoring tied to the filter.

How I work
All emissions software work is carried out fully mobile across Bridgend, Cardiff, Swansea and the M4 corridor. Your original ECU file is always read and saved first, so the vehicle can be returned to standard at any time.
I’ll always be straight with you about the legal position. These solutions are supplied strictly for off-road, motorsport or export use — if your vehicle doesn’t fall into one of those categories, I’ll tell you rather than carry out work that would make it illegal to drive on the road.
