W204 C63 AMG - misfiring, rough idle, fault codes

[8bit]

Had the car out this morning for a run - absolutely fine. Went to go into town in the afternoon and noticed it sounded weird, vibrating on idle and shaking badly above about 2krpm.

Turned around and came straight home, checked for fault codes and found:

• P0300: Random/Multiple Cylinder Misfire Detected
• P0305: Cylinder 5 Misfire Detected
• P0306: Cylinder 6 Misfire Detected
• P0307: Cylinder 7 Misfire Detected
• P0308: Cylinder 8 Misfire Detected

I cleared the codes later and backed the car into the garage - seemed fine but then I didn't really put any load on it.

Some Googling suggests possible O2 sensor fault, primary catalytic converter failure or failing camshaft adjuster or sensor. Where should I be looking first? Which bank has cylinders 5 through 8?

I was in town at the weekend for a photoshoot (I have a sideline business as a photographer), grabbed a few quick snaps of my car afterwards...
