X5 computer problems? Or electrical?

[jmweb]

On my way home today I experienced a few problems. They were:

My automatic sensor wipers worked when I turned it one click up. It went at the same speed the whole time but this is the first time I seen the one click up work.

My suspension (arrows pointing up/down) was on. It seems to come on when there is 4-5 people in the suv and then turns off over time.

My stereo did not work when I tried the button (usually does).

I tried pushing the lock/unlock button on my key and it wouldn't lock/unlock.

I plugged in my code reader and nothing came up. It showed no errors. I have the peake research tool.

Do you think these problems are related and do you think its a computer or electrical problem?
