I have the parking brake issue as well, very new to the E70 So when I applied the brake and it became stuck on I legitimately thought I was stuck until I found a YouTube video showing the emergency release. I constantly have the orange P sign and a constant fault code stored 006031 EMF Emergency Release Detected. Even after ISTA+ fault clearence it still remains, what's the reason for that?.. Like I get it if the actuator was stuck but why a permanent emergency release code. My plan was to remove the module and check the bowden cables and power cables to the actuator motor, I absolutely hate the fact that it's the transmission in Park stopping it from rolling at the moment.
