Choosing our dealership ensures repairs use OEM parts backed by factory warranties and performed by technicians trained on BMW systems. We also offer service financing so you can resolve urgent repairs immediately and pay over time, plus periodic service specials that may lower your initial cost.

2022 BMW 8 Series Gran Coupe Check Engine Light Codes

Understanding common check engine light codes for the 2022 BMW 8 Series Gran Coupe helps owners in Decatur make smart service decisions. Typical codes we see at Nalley BMW of Decatur include P0300 (random/multiple misfires), P0420 (catalytic converter efficiency low), P0171 (system too lean), P0455 (evaporative emissions leak), and P0128 (coolant thermostat). Left unresolved, these can cause progressive damage: misfires can harm a catalytic converter (repair costs $1,000–$3,000+), a faulty oxygen sensor left in place may reduce fuel economy and cause premature catalyst wear ($200–$600 for sensors), and EVAP leaks can lead to emissions failures and repeated check engine alerts (simple cap fixes are inexpensive, major repairs more).
