Check Engine Light Flashing

The check engine light flashing on a 2012 BMW ALPINA B7 is an urgent indicator that a misfire or severe engine issue may be causing catalytic converter damage or risking further engine harm. A flashing light typically means immediate shutdown of combustion is occurring in one or more cylinders, which can raise exhaust temperatures and damage emissions components — creating costly repairs if ignored. At Nalley BMW of Decatur, our factory-trained technicians perform a prioritized inspection to protect performance and long-term ownership value. We start with a quick, OEM-level scan, compression and ignition checks, and targeted tests that isolate electrical, fuel, or turbocharging problems. Customers benefit from clear estimates, OEM parts, and genuine BMW procedures that preserve warranties and reliability. Ask about our current service specials and service financing to address issues now and spread payments over time. If you see a flashing light, don’t drive far — contact us and schedule service so we can diagnose and secure your vehicle promptly.

2012 BMW ALPINA B7 Check Engine Light Codes

Common diagnostic trouble codes on a 2012 BMW ALPINA B7 include misfire-related P0300-series codes, oxygen sensor faults (P0130–P0167), and turbo/boost sensor codes.
