Dear All,
I come here today to share with and ask you for an advice.
without further due, here is my story.

one beautiful morning, I was heading to my class when my ML won't start and it showed a "start error" msg.
a taxi solved the issue for the day and the next morning I decided to take to a Mercedes mechanic.

now what happened there is a disgrace for all mechanics around the world. this guy just started smacking the fuse box and trying to "restore a loose connection" between the fuse box and AAM.
will what do you know it started just enough to reach a close gas station 10 km away and same thing happened again.
the mechanic now decided to check the AAM and DAS and see what might be the issue.

as he proceeded to remove the AAM, he broke the connection copper teeth between the AAM and fuse box.

so I did what a law abiding citizen would do and bought a fuse box with AAM along with it and wired them to my ML.
I took it to a shop where they program "mostly" Mercedes keys and ignition systems.
I was told that after many failures, they were able to make the remote control function works with no luck to make the engine start and "start error" remains flashing.
I was told that there is an electrical problem with the car because they tried to connect my newly programmed AAM to another ML and it worked so it is not an AAM malfunction.

what should I do next because this process is sucking money and with no promising results. I started thinking selling it to a scrap yard, but I love this car. PLEASE help me!!

PS.
- I jumped started the car 2 weeks before this happens. "i don't think it matters but it happened"
- I have both keys and none worked.
- after programming, the keys and all electrical activities returned along with the start error msg.

Thank you,,,
