Why replace both ignition coils and spark plugs together?
Failing coils accelerate spark plug electrode wear, while high-resistance fouled plugs force coils hotter and shorten coil life. Matched coil and iridium plug sets balance resistance across every cylinder.
How do I diagnose a bad ignition coil on an X3?
Common symptoms include hesitation under load, poor fuel economy, rough idle, and cylinder-specific misfire codes (P0301–P0306). Swapping the suspect coil to another cylinder and re-scanning to see if the code follows confirms a faulty unit.
