Check Engine Light Flashing

A flashing check engine light in a 2019 BMW 3 Series indicates a potentially severe condition — commonly an engine misfire that risks catalytic converter damage, poor drivability, and reduced fuel economy.

Our certified BMW technicians use dealer-level scanners and live-data analysis to pinpoint misfires, ignition faults, and fuel or compression problems accurately. Fixing the right issue the first time preserves catalytic converter life and prevents cascading failures that are far more expensive.
