Man oh man guys I've been running into issues with my 2019 330i.

I always had an issue with a slight rattle at the rear of the car (they couldn't figure out where it came from), but never anything too bad.

However, since they did the wiring harness/battery service bulletin my car throws electrical malfunction on shutdown warnings, high battery discharge warnings, and heck once just refused to start for a few minutes.

The cherry on top is the ASD speaker rattles in sport mode sometimes now too.
