BMW 528i intermittent starting issue and loss of power during left turns after replacing DME, battery, and alternator on BMW 528i

Some BMW 528i owners report experiencing intermittent starting issues and loss of power during left turns, particularly after replacing the DME, battery, and alternator. These problems may stem from common causes such as battery, alternator, or starter issues, and it's crucial to reset the Engine Control Module (ECM) after battery replacement to ensure proper functioning. Additionally, loose connections or power cuts to the DME can lead to starting difficulties, especially if voltage at pin #27 is absent. Furthermore, loss of power during left turns could indicate fuel delivery system issues or potential problems with the immobilizer system. Owners are advised to check battery health, inspect electrical connections for security, and ensure the alternator is functioning correctly. If these issues persist, seeking professional inspection may be necessary to diagnose and resolve any underlying electrical or mechanical problems.
