Does this sound like a misfire to you?

I'm getting a cylinder 2 and 3 misfire and a 2C3A oxygen sensor code on my N54 335i. I'm also hearing a weird noise. You'll hear it the background try and ignore the injector sound ticking sounds.

Not exactly sure that it sounds like a misfire. Especially if you aren't throwing any misfire codes. But have you changed plugs, could, or injectors recently? Is the car running poorly?

Which o2 sensor is throwing the fault? It does sound like a misfire have you try swapping the coils around to see if it follows? If it's the pre turbo o2 sensor that can also cause the misfire due to it not scheduling fuel correctly.
