Can worn spark plugs cause knocking? On my code reader for my f30 335i it says super-knocking, cylinder 6: injection switch-off, permanent injection deactivation, injection switch-off please help! If it doesn't can someone help find me a solution.
I scanned the car 2 days ago and it had no faults and yesterday it had 3 faults.

I would start by replacing the spark plug and coil pack on that cylinder.

Do you think it's that? I just bought some double spark plugs waiting for them to get in? Do you by any chance know which cylinder is 6 in the engine bay

Is the engine knocking, missing or running rough? The codes seem to say the injector is not working or shut down.

The other night it was revving high with little power and started shaking when I was braking.

IF the injector is not working as the codes indicate then that msy ne the cause of the rough running and knocking. I think you need an experienced BMW mechanic to take a look. The super knocking message can be the result of carbon buildup too.

Arrow shows the front is cylinder 1 so that of course cylinder 6 in the very back
Thats Assuming since its the 335i (not the 340i) it has the N55 engine
