BMW 328i cylinder 2 misfire issue with low compression after spark plug and coil pack replacement on BMW 328i

Some BMW 328i owners report experiencing a cylinder 2 misfire issue accompanied by low compression even after replacing the spark plug and coil pack. This misfire may stem from various factors, including faulty ignition components, fuel delivery problems, or mechanical issues within the engine. Additionally, low compression in the cylinder could indicate leaking valves or worn piston rings, which, when combined with a specific misfire code like P0302, suggests problems specifically with cylinder #2. Even after replacing ignition parts, some owners find that underlying issues with other components may still cause the misfire. To address these concerns, further diagnostic testing, such as a leakdown test, is recommended to assess cylinder condition, and seeking a professional inspection from a mechanic or BMW specialist can help accurately diagnose and resolve the issues.
