[M52turbo]

Hey there guys I'm here because I just ran into an issue with my 2007 bmw 328i e90 2 days ago. First I would like to thank everyone who will be helping me out. I got my car 4 years ago and never gave me any problem just gave her maintenance she took care of me. But 2 days ago I parked my car and when I wanted to go to the store it was dead no interior lights or anything I replace my started and battery about 9 months ago. Took the battery to get checked and its 100% even after 2 days just sitting there. Can someone lead me the right way i don't know what to do to fix it plus its dead and can't run a scanner. Please and thank you
