Warning light
Saw this tonight, according to the owners manual, this warning light is because of a defective bulb. I checked all lights on the car. I can't find any defective light bulb on the car. Anyone has this experienced before?

One of the bulbs isn't making proper resistance and your M believes that the bulb is out. The best thing to do is to just get a whole new set of replacement bulbs or you can try going about finding the one that it is by trial and error, it could be more than one bulb or just one bulb on the car. There are some LED upgrades if you feel like splurging that are quite safe (I used weisslicht) but there are other solutions available as well.
Your M sends an electrical signal to all of the lights repeatedly and when it does it reads what electrical current is remaining from the signal that it gave to the bulb. On standard bulbs, you won't see anything, on LEDs they'll almost illuminate entirely. It's quite interesting, but basically this electrical current is what your vehicle is using to check the resistance mentioned above in order to identify if there is not enough current being consumed by the light bulbs themselves throughout the entire lighting system (exterior only) of your vehicle. Hope that helps.
