Q: New battery installation...turn signals, gas guage, & trunk are not working? on 2001 Mercedes-Benz C320

Rookie cbe0621eac06868b3efe0d8d1d3611e23c60d3114864ea2ec19a68cfbd3eebab
I had the typical power seat module problem...draining the battery...installed new battery..unplugged passenger module. Next it was the driver side module draining the ne battery...unplugged it... Sometime later everytime I would lock my car, the exterior front and back lights would flash for several minutes...no siren. MB repair shop installed a new Alarm/Siren package...exterior lights quit flashing, next interior lights or trunk light was flashing-interior especially after locking the car. After installation of new alarm/siren--siren didn't work...didn't care..but now it was like a silent alarm was going off everytime I locked the car. It would happen one week...then not the next...battery went dead had to jump it..then it was fine for a month or so.. Drove it short distances and had to lock it for a couple of days...battery was dead again...this time worse than before...remote wouldn't work, trunk will not open. Manually unlocked...jumped the car and drove for new battery installation yesterday....afterwards turn signals do not work, still cannot open the trunk, fuel guage shows empty...but is full. I resynced the smart key...it lock/unlocks from the passenger side...but now not the driver's side...
