Hi all, I got my M3 this weekend finally and I noticed that when my 11 year old daughter sits in the passenger seat (she weighs 84 lbs) I get the passenger airbag notification off warning. No notification when my wife sits there (125 lbs) or testing with both kids in seat it works fine as well. Is this normal? Shouldn't an 85lbs child be sufficient to trigger the airbag? Is this something worth discussing with service? Thanks In advance.
