HELP! Parasitic Battery Drain After Accident

[BMW_E53]

Thanks for all the replies. I’m currently having the battery charged and if the current one holds charge will put it back in the car and run the tests and will report back. Hopefully I’ll be able to find it to avoid having to bring it to the shop.

From what I know everything works as it should radio, nav screen, etc. only thing illuminated on the dash is the airbag light after start up. I know the NAV cd player can’t read the disc anymore for some reason, I wonder if that is the culprit and the draw began before the accident.

Will check the FSU, but it was replaced a few years ago with a new one so not sure if it should fail already.
