w20312

I recently got a 2012 250 for really cheap. Here’s the issue I’m having though, no power to anything besides radio and instrument cluster. Literally no fuel pump hum or anything Checked fuses in the front fuse and rear fuse box and all seem to check out besides maybe 3-4 in the front fuse box that I’m assuming only are on when the car is running. also tried to run my innova obd2 on it and it said something about no ECU communication.The car also doesn’t show what gear it’s stationary in. Can anyone throw some pointers out for me?

Did you check for large amp fuses, usually located closeby your starter battery?

2012 is not W203. You're in the wrong forum.
