I have a 2004 325i w/SMG transmission I need to do some work on. The clutch is shuttering and the airbag light is on. You have to have "Software" to work on and replace the clutch. I assume the same software can troubleshoot the airbag light. Can someone recommend BMW GT1 software or another software, where it may be purchased and how much it costs. It easily pays off changing the clutch as Indy Shops want $1,600- 1,800 and the dealer in excess of 2k. Clutch kit is $269.
