BMW 328i engine shuts off while idling with sudden jerking during driving, undiagnosed issue on BMW 328i

Some BMW 328i owners report experiencing engine shutdowns while idling and sudden jerking during driving, which may be attributed to several underlying issues. These owners often notice engine misfires, indicating potential problems with the ignition system, such as faulty spark plugs or coils. Additionally, symptoms related to a faulty Idle Control Valve (ICV) may include rough idling and stalling, which can often be resolved by cleaning or replacing the ICV. Some owners have experienced engine shutdowns due to belt seizure, resulting in a loss of power, though the engine may restart smoothly without rough idling. Issues with the Mass Air Flow (MAF) sensor and error codes such as P0101 can also lead to engine shutdowns, alongside other sensor-related errors. Electrical system problems are another concern, with some owners reporting that their vehicle shuts off while driving and fails to restart, potentially due to alternator or battery issues. Other factors, including vacuum leaks, fuel pump/filter problems, or low-quality fuel, may also contribute to these symptoms. For sudden stalling while driving, proper diagnosis by a qualified mechanic is essential to identify the exact cause and ensure prompt resolution.
