They diagnosed it as a faulty power control module. I took the module and shipped it to Solo Auto Electronics in Miami. They went through it and sent it back


I also found the exact same module on the internet from a salvage yard. and bought it. I shipped it to Beckman Technologies in North Carolina and the unlocked it

so then I had 2 modules. I towed my car back to the same mechanic and still no results.
In my frustration I found a guy who specializes in Mercedes and said he's worked on Crossfires. I towed it there and now waiting for him to diagnose all over again
