Make sure you did not disable the EGR system — it's against federal emissions regulations to remove or render inoperative emission control devices. If the EGR is still active, please post all diagnostic trouble codes (DTCs) and specify your transmission type, as troubleshooting varies by model. Loss of turbo communication and no boost with a persistent P2BAC code could indicate issues with the EGR valve, sensor wiring, or internal turbo components. Even after cleaning the EGR valve, if the code persists, further diagnostics are needed.
