So i replaced my battery for my e92 sedan and after i replaced it a "lighting system malfunction, stop vehicle" code came on and now the interior lights dont turn on and my windows dont roll down on the driver or passenger buttons but in the back of the car i can roll those windows down going back there. Everything else seems be working fine except for those. Is it because i havent registered the battery or is it another issue? Any ideas on how to solve this?

Nope not a registration issue .
Could be your Frm module is blown.(controls the lights and windows)
There was a recall on these in some years.
Typical it blows when updating modules but a spike when hooking up the battery
could do it.

If you want to nail it down get a Copy of BMW standard tools software and a K/D can
cable. You also need a PC to run it .
Or for a phone bimmergeeks pro tool which also is capable of registering the battery
and a bunch of other stuff.

Your FRM Module is probably dead. You can try to connect with the module with Tool32 and try to flash the newest firmware with Winkfp. If this doesnt work, you have to repair it with a Programmer.
