BMW 428i Gran Coupe recurring fuel system and drivetrain error leading to shutdown despite recent battery and fuel pump replacements on BMW 428i Gran Coupe

Some BMW 428i Gran Coupe owners report experiencing recurring fuel system and drivetrain errors despite recent battery and fuel pump replacements. These issues may stem from known fuel pump problems, such as hard starting, intermittent stalling, and drivetrain malfunction errors, particularly in models from 2014 to 2015. Additionally, the drivetrain malfunction message can indicate engine or transmission component problems, potentially triggering fail-safe driving mode to prevent further damage. Some owners also encounter fuel pump control module failures, which can complicate fuel system functionality. Software updates may resolve issues related to low pressure fuel sensors or fuel control modules, so checking for necessary updates is advisable. Moreover, a malfunctioning fuel pump can lead to no-start conditions or stalling, posing safety risks while driving. To address these recurring issues effectively, it is recommended that owners seek a thorough diagnostic check by a certified BMW technician to ensure optimal vehicle performance and safety.
