Common check engine light codes for the 2015 BMW 6 Series include P0300 (random/multiple misfires), P0420 (catalytic converter efficiency below threshold), P0171/P0174 (lean condition), and O2 sensor codes. Left unresolved, misfires (P0300) can ruin the catalytic converter — an expensive repair — while P0420 can indicate converter or sensor failure that harms emissions compliance.
