My car wouldn't start the other day. I replaced the battery and now it starts and drives just fine, BUT my airbag light is on and my driver side window won't auto-up/ move when you open the door.
Anyone have an idea where I should start to find the fix?

Reset the srs light

Reinitiize the window. Something like holding up on the switch for about 20 seconds after it reaches the top.

Hopefully just a minor hiccup with the low battery problem.

JB4 only reads DME codes, not other modules.


This. You could have bricked the FRM with the low voltage condition, you will need a bmw scanner to reset and clear all the low voltage codes in the system, did you try re-initializing the window switch by any chance?

Man this must be the season for failed FRMs, I have two cars that now have bricked FRMs, both happened last week.
One battery died so I swapped in the battery from the other car since it was down with a broke axle.
No big deal I thought, until I realized my damn EEPROM programmer was also bricked.

¯\_(ツ)_/¯
