There are a few posts about it. I don't remember exactly, but it's something like the ECU sees big differences in wheel speeds and decides your brakes must be failing. Afaik it only happens on track. Somebody said his dealer told him it only happens to cars with tunes. I don't know. |
It's a calculation of brake temps based on a number of different variables. Such a road speed, brake on time, brake pressure etc. It first came out on the E53 X5 as a preventative measure due to brake application due to all wheel drive system intervention. It s feature that has progressed in its function, but at the track it can be a nuisance if you really push hard.
