Troubleshooting Phantom Input BMW E90 Board Computer

I own a 2008 BMW 328i Sedan, and I really do love this car. Mechanically its perfect, electrically well… its interesting.

One of the problems i’ve had with this car is that the Board Computer display in the Center of the Instrument Cluster likes to change settings on its own or stops working entirely.

Here is the first video of symptoms, the BC button is inoperative.

I took it in to get it serviced because it was a BMW under the CPO program, they had it for about a week and could not replicate the problem. In person and over the phone they told me they were working with BMW Corporate to figure out the problem. They gave it back to me with a new Control Stalk (ZSL) and said that the melted right turn indicator socket was the cause and to fix the problem it needed to be replaced, however that was out of warranty.

So I did.

But it never really resolved the problem. This morning I was able to capture a new symptom, the BC Operates Independently.

I’m hoping to get some ideas about what I can do to fix this. Because trying to reset the service intervals, and change settings in the car can be very problematic when the BC Button is Inoperative. Anyone have ideas?
