Hi, hope all is well.

I have a 2010 BMW 320i with the N46 engine, 190000km on it. It's had its share of problems, it's got a new timing chain, gearbox, vanos solenoids etc .

The car seems to run alright now apart from a cylinder 1 misfire I just can't figure out, I've been using Bimmerlink to log the values. It's always a misfire on cylinder 1. So far I've replaced the spark plugs, switched ignition coils with a different car, swopped injectors, new vanos solenoids (which did seem to fix a different issue). Nothing seemed to help the cyl 1 misfire. I was wondering if someone would please take the time to read through the log, I find the air mass fluctuations particularly interesting. I do notice the misfire seems to only be apparent when the car warms up. But if it's a vacuum leak or something of the sort surely it would not just register a misfire on cylinder 1?

The log is attached, any insight is appreciated.
