Having recently purchased my first BMW, a nice 2001 540i Sport, I discovered that there have been 3 recalls for this vehicle. One for the airbags and 2 for the cooling fan. My questions are, (1) does BMW only perform the corrective actions for the original buyer, or is it available to subsequent buyers if not completed already, and (2) how can I determine if they have been done? Having been in an automobile where the airbags deployed, I would not like having one deploy inadvertantly, scaring me out of 3 years growth. Any information would be greatly appreciated. Thanks.
