What the Door Ajar Warning Light Means on a Mini Cooper S
The door-ajar light on a Mini Cooper S indicates a door (or the boot/bonnet) is not fully latched. It is a safety and security warning, and a stubborn one usually means a door switch or latch sensor has failed.

Is It Safe to Drive With the Door Ajar Warning Light On?
Safe-to-drive depends on judgement, and here is the technician's version for a Mini Cooper S: respect the colour, respect the behaviour.

Why is the Door Ajar Warning Light on in my Mini Cooper S?
Your Mini Cooper S turned on the Door Ajar Warning Light after its self-diagnostics flagged an issue in that system. Because several different faults can trigger the same symbol, the smart first move is an OBD-II scan to pull the specific code before you spend any money.
Can I keep driving with the Door Ajar Warning Light on?
Short answer: sometimes, but not indefinitely. Given this indicator's low priority, respect the warning colour and the car's behaviour. When in doubt with your Mini Cooper S, the safe choice is to stop and have it checked rather than risk further damage.
How much does it cost to fix the Door Ajar Warning Light on a Mini Cooper S?
Cost varies widely because the Door Ajar Warning Light can stem from several causes on a Mini Cooper S. Some fixes are almost free — tightening a cap or a connector — while others involve a sensor or component and its labour.

Will the Door Ajar Warning Light reset itself on a Mini Cooper S?
