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...

hello there,
i have exactly the same issu with my ml63 amg w164
went for normal ride then kaput engine is misfiring and shaking
codes are exactly the same as yours = all cylinders in bank 2 are misfiring
please can you help me with that ? how did you resolve the problem ??
 
Hi, sorry to hear about your engine troubles.

In my case, it happened once then never happened again so I didn't have to do anything as such. I just noted the codes down, cleared them and left it alone for a while and then started it later on to take it round the block to see if it was still a problem but it was fine.

Have you tried that?
