If your vehicle is suffering from EGR-related issues, such as loss of power, excessive smoke, or warning lights, our EGR delete and remap service offers a reliable and cost-effective solution. A failing EGR system can cause poor engine performance, increased fuel consumption, and expensive repair bills. At Onyx Performance in Slough, we specialise in professional EGR removal and ECU remapping, ensuring your vehicle runs smoothly without EGR-related faults.

The EGR (Exhaust Gas Recirculation) system is designed to reduce emissions by recirculating exhaust gases back into the engine. However, over time, carbon deposits build up, causing the EGR valve to stick open or closed, leading to poor performance, turbo lag, increased fuel consumption, and even engine damage. If left untreated, a blocked EGR system can make the vehicle undrivable.

Our EGR delete service permanently disables the EGR function, preventing carbon buildup and eliminating common EGR fault codes such as P0401 (EGR Flow Insufficient) and P0404 (EGR Valve Stuck). This process improves throttle response, fuel efficiency, and overall reliability. We achieve this by reprogramming the ECU to deactivate the EGR system, ensuring the vehicle runs without any warning lights or limp mode issues. If necessary, we also blank the EGR valve to stop any residual gas flow.
