Here are the reasons why the 2011 BMW 5 Series won't start: 1. Severe carbon buildup: Excessive carbon deposits can make it difficult to start the vehicle, causing idle shaking. 2. Ignition system failure: It is necessary to check the vehicle's spark plugs and high-voltage wires. Abnormal operation of the ignition system can lead to this situation, resulting in idle shaking or difficulty starting. 3. Unstable fuel system pressure: If the vehicle's fuel pump cannot supply fuel properly, it can cause poor fuel atomization or failure to open the fuel injectors, leading to cylinder misfire shaking or failure to start. 4. Insufficient engine cylinder pressure: Due to time-related issues, the vehicle's engine may have exceeded its service life and can no longer function properly, resulting in intermittent idle shaking. In such cases, prompt repair at a service center is necessary. Regular inspections and maintenance are essential to prolong the vehicle's service life.
