By brakes overheating limp mode you are just referring to them fading and having to back off, not due to some mystery sensor?
It's not a mystery sensor. It's something based on the wheel speed sensors and I don't know what else. Several 135i owners from all over have posted that their dealers showed them the codes. Someone posted just a few days ago after DriveHard said he didn't believe it that it's a published feature that was developed first for the X3 I think. That's all I know about it.
