The Exhaust Gas Recirculation (EGR) system is a common source of engine problems in diesel vehicles. Over time, carbon deposits can clog the EGR valve, leading to loss of power, increased fuel consumption, rough idling, and expensive repairs. If the system malfunctions, it can trigger dashboard warning lights, excessive smoke, and even force your vehicle into limp mode.

This means your engine will no longer suffer from carbon buildup or EGR-related failures, resulting in improved performance, smoother acceleration, and lower maintenance costs.
