I finally got a chance to check the start/stop coding. I did have the ECU DME Auto Start Stop Function coded as NOT ACTIVE. I reverted to backup settings, changing it to ACTIVE and the clutch pedal actuation no longer deactivates the parking brake.

Yesterday afternoon my service advisor called me back from my local dealer and he reported the shop foreman said that behavior is normal. Obviously we are modifying our cars at our own peril, but the fact that the BMW service departments are not able to distinguish that these behaviors are NOT normal behavior, is definitely a safety concern, even if the behavior is due to modifications.

I left the NHTSA investigator a voicemail with my results and will update those interested in any other developments.

That's probably about the best ending this story could have, since there's zero need to ever code the AS/S as not active. There's a physical button that disables AS/S, and the setting persists across sessions. Unlike so many other settings in the G87

I mean, it's a better ending than it being a factory bug. Now, anyone know the authors of Bimmercode, etc, because maybe they should disable this setting (or at least put a warning on it)?

I take this as another example which I find myself getting more annoyed with each year I get older: you are often best served to become your own expert. It is incredibly frustrating when you pay people for a service (dealer maintenance in this case), yet you end up finding out/learning more than they do.

I learned several things reading through this entire thread, so I appreciate you sharing this with everyone.

This has been the case since I purchased my first car 31 years ago. I had a friend who was a certified Chevy tech, and I wouldn't trust him to work on my Camaro SS at the time (he had a similar Camaro SS). The techs just follow service manuals and what the computer tells them to do, they don't really know how to diagnose or fix anything.

It is funny I was reading this thinking this was a bonus and one more reason i should dump my f87 for the g87. How is this so unsafe? Does the same thing happen every time the clutch is pushed in? If not then it is unacceptable and I understand. Any time I get in my car and push the clutch in I intend to move the car. Even on hills if I know that the car operates this way this is a not an issue. I have had other cars that did this and it was not a problem. It stops my wife form being able to kill the parking brake accidentally. If she has to move my car out of her way or the rare occasion she drives it she cant kill the parking brake. This is like complaining to ykk because I got caught in the zipper. You know what you have act accordingly. Hopefully my 2025 will do this when I get it or I can make it do it with bimmer code.

I don't think it's a big problem personally, but no one is expecting the clutch to disengage the parking brake because it doesn't do that on any other car and it never has on any car with manual parking brake clearly.

It's not when you push it in, it's when you release. You can engage the parking brake then take your foot off the clutch and it will release. That's my main issue.

Mine was also the start/stop. I didn't think I had deactivated because it still was able to be turned on and off. Sure enough it was deactivated. Reset it and all works normal now.

That doesn't excuse the moron in the service department saying it was normal though. He damn well knew it wasn't.

Thanks to everyone that looked into this and offered suggestions. This community is helpful (usually )

I have this issue as well, it's not every single time I clutch in but it is sometimes... i don't have stop/start activated - are you saying if i enable start stop then it'll stop this happening?

If you used Bimmercode, and changed the auto start stop function to "not active", the parking brake will release itself simply with clutch activation.

Changing the setting back to "active" solved my issue.
