Common check engine light codes for the 2018 BMW ALPINA B7 frequently relate to ignition coils, oxygen sensors, turbocharger boost control, and evaporative emissions system faults. Left unaddressed, an ignition coil fault can cause misfires that damage catalytic converters — a costly repair. Faulty oxygen sensors reduce efficiency and increase emissions, while turbocharger or boost-control issues can degrade performance and lead to expensive turbo repairs. Evaporative system leaks may seem minor but can trigger repeated warning lights and failed emissions tests.
