Mein Auto: 97 bmw 740il
Replaced driver side window regulator now airbag light on

So I followed a youtube tutorial on how to replace the 97 bmw 740il window reulator. It had me unhook the battery, so the airbag would not accidetally deploy. When I was done replacing the regulator I hooked the air bag back up and then reconnected the battery. Now the air bag light blinks once then goes to solid on. I tried unhooking the batter for over 15 mins to reset it and still it came back on. Can anybody help? Thanks! Bruce J

I hope you at least got the regulator taken care of...

Once the airbag light is on you will need to read the SRS codes, fix the problem (if any) and clear the codes to turn the light off. That system is really a PITA.

B800 SRS scanner

I had the air bag light come on and stay on for the same reason. I purchased a generic B800 code scanner/SRS reset tool off of eBay for $21.45. It arrived pretty quickly from Hong Kong. It worked perfectly - no more air bag light.

So far I have replaced three out of eight window regulators on the two BMW 740s I own. I recommend the aftermarket window regulators over the oem ones with the pink guides which constantly break. The aftermarket regulators are inexpensive and pretty easy to install. You do need an external female star socket set to remove a couple of the nuts, and a B800 scanner to clear the air bag light when you are done.
