Today I was very close to brick my F55 Cooper AT
Here's what I tried to code with bimmercode:
* Start the engine without pressing brake. This option simple made my car not starting the engine at all. Nor with brake pedal down, nor without it - the engine didn't start. (I tried a long press on the start button, too). Then I tried "recover from backup", but it constantly failed reaching 15%. Finally I got it fixed setting this option back to "inactive". Oh God, it helped!
* Sounds when locking-unlocking the car. This option is now in the settings menu, but I can't enable it. Should I have an alarm to get speakers to beep?
* Video (codecs, video in movement) - still had no chance to test
* Start-stop off by default - it's the only option which worked
To sum it up, my experience with bimmercode is negative.
