The P0400 code indicates an issue with the Exhaust Gas Recirculation (EGR) system, while P0100 relates to a Mass Air Flow (MAF) sensor problem. Start by checking the MAF sensor for dirt or debris and clean it if necessary. Ensure all connections are secure. If the issue persists, consider inspecting the EGR valve for blockages or malfunctions. Let me know how it goes or if you have further questions!
