Ok I try today and see if the light works , yesterday it didn't work. It should not happen for such expensive lights.

FYI, the brake lights are standard LED on the CS.

Only the actual taillights are OLED. All the other lights in the rear cluster, brake, turn indicator, reverse and fog are LED lit.

Can you imagine these failing when the car is 6/7/10 years old... yes sir that will be about 5 grand per side to replace!!

Right, I can't immagine, that's why I will not keep the car after few years. But who will?

In three months of ownership I had many errors and went to shop 4 times. I don't trust the car no matter how much I enjoy driving it.

You need to code out the brake light "Hot" checks in the REM/BDC module to avoid this error message.

These hot/cold bulb pulse checks was originally designed exclusively for incandescent bulbs but for some strange reason, BMW still leaves it on for LEDs, even though the lower power pull of LEDs sometimes triggers an unwarranted fault code, even if they're working perfectly fine. Go figure :

Thanks but the light doesn't work. I have an appointment tomorrow and let you know.
In the meantime, did anyone experience some metallic rattle under acceleration coming from the back center of the car ?

I mean this in the least sarcastic way, but isn't that just rasp? These cars rasp like hell unless you load them up with resonators.

No, it wasn't there before, it rattles when it reaches some resonance like something is loose. I have a video of it.

Is yours in the interior or exterior? Come to think of it, I have some annoying buzz coming from around my back seat area. Almost like a panel or piece of trim is rubbing. Haven't gotten around to putting someone in the back seat to diagnose.

Around back seat but seems in the center. It starts if I hit the bump and accelerate immediately, then I can play with the pedal to increase or decrease the vibrations which crate the rattle.
