Ok, my E36 used to beep when I had my door open and
1) Key was in the ignition
2) Lights were on (VERY useful)
Now my E46, the car beeps when the door is open, period. Someone told me there should be a different tone when the key is in the ignition and someone told me it should not beep at all if the key is not in.
What is the deal?
FYI, one guy put his computer analyzer thing on there (a mid-cheaper model) and it showed no computer errors.
