Misfire codes on 2013 650i

[Puddin]

My daughter has a 2013 650i with ~30,000 miles. Recently she has got the following misfire codes once about 2 months ago and then again 2 days ago both were within 36 hours of a fill up. When it has happened the car seems to have a miss and rough idle but then seems to correct itself. I have included pics of our code reader screen any help would be appreciated, thanks in advance.

I had a thread on the exact same topic about a year ago. I have the same car at the same mileage. It took 3 visits to the stealership (under warranty) to get it fixed. First, they replaced the crankcase vent line - that's a known issue that they would've done anyhow and I believe they were just trying to string me along until the warranty expired in 2 more months. I called them on it cause it didn't fix the problem. They then replaced the fuel injectors in Cylinders #3 and #6. My research showed that these - for some reason - seem to be the cylinders that have problems. I asked them to replace all the plugs and coils too (for free), but they would not. 2 weeks later, it was back in for the same problem. They replaced coil #6, and that fixed the problem for the last year. I plan on replacing the other 7 coils and plugs myself now next week as preventive to avoid these misfires ("malfunction" notices).
