What Causes a BMW 5 Series to Shake and Stall After Ignition?

[DelJoshua]

The reasons why a BMW 5 Series shakes and stalls after ignition: 1. Triggered car anti-theft system: If the car anti-theft system is triggered, the car engine can start but cannot operate normally, so the vehicle will stall after starting. This situation is prone to occur after replacing the car key, so it is necessary to recode the key after replacing it or installing a new battery. 2. Ignition switch failure: If the car ignition switch fails, the car will experience issues such as stalling after starting and the vehicle fault warning light turning on. This situation is relatively complex and requires inspection and repair by professionals at an auto repair shop or 4S store. 3. Severe engine carbon deposits: If the car engine has severe carbon deposits and the fuel cannot effectively burn in the cylinder, the vehicle will stall after starting. In this case, the engine carbon deposits need to be cleaned promptly. 4. Car fuel system pressure: If the car lacks fuel system pressure, the fuel will not burn effectively. This situation requires professionals to inspect the car fuel system.
