Rattling noise under car '04 C240

I'm 99% sure its the catalytic converter, our car in the video.

But when I scanned the car via OBDII I got mad errors, Misfires on C1,2,3, MAF Circuit High Input and another.(Codes below)
P0301 - Misfire Cylinder 1
P0302 - Misfire Cylinder 2
P0303 - Misfire Cylinder 3
P0103 - Mass or Volume Air Flow Circuit High Input
C0303 - (No Info)

I wasn't driving the car at the time, I was overseas but when I came back and my brother picked me up I heard it and got suspicious, before I could do any research it dies on him while he's driving to work, had to pick him up in my trusty Volvo(sorry guys).
He said he had trouble accelerating and it died completely when he put it in reverse.

Now I think the broken part in the CC is causing sensors to go off causing a incorrect of airflow through the MAF which is causing cylinder misfires, but I don't know enough to confirm that.

Anyone know what it could be and how much it would cost me? I'm hoping I just gotta replace the Cat.

Also has anyone broken the steering wheel adjustment, I can't seem to lock it now it goes up down and telescopes..
