The check engine light in a BMW illuminates when the onboard system detects a problem affecting engine performance or emissions. Common causes include a faulty oxygen sensor disrupting the air-fuel mixture, a loose or damaged fuel cap triggering evaporative emission leaks, or a malfunctioning mass airflow sensor affecting fuel delivery. <br />Ignition issues such as worn spark plugs or failing ignition coils can cause misfires, while catalytic converter problems reduce exhaust efficiency and increase emissions. Although some causes are minor, ignoring the warning can lead to reduced fuel efficiency, poor drivability, or costly engine damage. <br />Prompt diagnosis with a professional scanner helps identify the exact issue and ensures timely, accurate repairs.<br />https://emcnv.com/<br />Follow Us On:<br />Facebook:https://www.facebook.com/EuropeanMotorCarsVegas<br />Instagram:https://www.instagram.com/explore/locations/410906268/emc-european-motor-cars/<br />#BMWEngineAlert #CheckEngineWarning #BMWServiceTips #EngineDiagnostics #GermanCarCare #BMWReliability #VehicleWarningLight #AutoCareGuide #BMWLife #SmartCarMaintenance
