One problem related to front air bag has been reported for the 2002 BMW 745. The most recently reported issues are listed below.
My vehicle is a 2002 BMW 745i that has an drive system and the latest warning note came up on the idrive screen that says, "fault in pass. -restraint system affecting airbag, belt tensioner or belt-force limiter. Fasten and continue to wear belts. Please contact the nearest BMW center". My research indicates that there is a service bulletin that BMW initiated that covers this issue for a 10 year period.
