i use it alot, maybe thats why. Honestly i think its one of the best parking brake technology BMW introduced. I like the fact that you can just sit in traffic set the parking brake and just relax. but it seems like the engineering finish sucks.

I have the latest software(PDC and camera).

I have had this problem before which i just released it manually from the trunk and it worked. Not this time though. This time the cable is not firm at all.
Its back at the dealer now. I will not use it anymore, unless i really need to.
