Overview

About our dpf & egr solutions

Diesel particulate filter (DPF) and exhaust gas recirculation (EGR) problems are among the most common issues on modern diesels, especially cars used mainly for short journeys. Left alone they can cause warning lights, limp mode, poor economy and failed emissions tests.

We diagnose the real cause of DPF and EGR faults and recommend the right solution for your vehicle and how you use it, so the problem is dealt with properly rather than papered over.
