Engine misfires in the BMW 2 Series can be caused by several factors, but faulty spark plugs are one of the most common culprits. Over time, spark plugs wear out due to carbon buildup, oil contamination, o r incorrect gaps. Here’s how to diagnose and resolve the issue:

Check for error codes: Use an OBD-II scanner to check for misfire-related trouble codes such as P0300-P0306.
Inspect spark plugs: Remove and check for excessive carbon deposits, oil fouling, o r a worn electrode.
Replace with OEM plugs: BMW recommends NGK o r Bosch spark plugs for the best performance. For Pakistan’s climate, iridium o r platinum spark plugs are ideal due to their longer lifespan and better resistance to wear.
Check ignition coils: If replacing spark plugs doesn’t fix the issue, weak ignition coils may also be a cause.
