so i bought this 2005 545i on ebay, and i received the car, i left it at the bodyshop and i pick it up a few weeks later, with the surprise that theres no audio, i remember i heard the beeping inside the car because the door was opened, now it doesnt beep anymore so i checked the back inside of the trunk and found this cut wires and it looks like its missing somenthing, and then i checked at the front passenger side and found some other cut wires its the same harness as the headligth and the horns, it also must be the same for the fog lamps and maybe the parking sensors, bu im not really sure if it has them in the front because the bumper doesnt have them, but it does have them on the back bumper, another thing the car now doesnt start and i think its the starter because it only make a one click noise when i try to start the car has a new battery and the ligths dont dim or anything, somenthing i think its important mention is that when i got the car it didnt started on its own because it had a bad battery so they connected a jump starter at the battery terminals in the trunk, the car started fine, later they needed to move the car and they did the same but the car would turn off whenever they disconected the jumpstarter, now the car doesnt want to start even with the jump starter connected it sounds like its gonna start but it just doesnt, and by its self just the click. any help is greatly appreciated i think the best help i can get is some pictures of someone elses car to know where the cables go, thanks.

 

Believe it or not, to me that looks like an easy fix, but I love automotive electronics. Just trace the harness until you find the other end of the wires and solder/splice in new connections. If I am seeing your picture correctly this looks like the front passenger wheel well. Good chance some of those wires relate to your charging/ignition system.

 

I'd start by splicing the same color wires together. Otherwise I would get a replacement harness.

 

so someone butchered your wires when the car was at the bodyshop? have them fix it. was your amp in the trunk taken?

 

+1 You sure they didn't steal anything?

I know this doesn't answer your question but it sounds like the shop stole something. I would take it back ASAP. You also may want to look that shop up with the BBB to see if other people have had issues with them.
