As a seasoned driver with years of experience, I've encountered the situation where a BMW Mini has power but fails to start several times. Although the dashboard lights up, the battery might be aging with high internal resistance, causing a voltage drop during startup that prevents the engine from turning. Check if the key's anti-theft system is properly recognized—sometimes the key battery is weak, leading to poor signal. Another common issue is a stuck or corroded starter motor or relay. Also, make sure the gear is in park or neutral, otherwise the car's anti-misstart feature will prevent ignition. A faulty fuel pump could also be the culprit—listen for a humming sound from the rear seats when starting. It's advisable to first use a multimeter to check the battery voltage; if it's below 10 volts, replace it. If the voltage is fine, don’t delay—take it to a professional repair shop to inspect the circuits and diagnostic codes. Safety comes first—don’t procrastinate.
