It might not be a contributing factor but were you using regular gas by chance?
Or maybe pissed someone off who put something in your tank ??

No, I was using shell premium since getting the car and no signs of tampering of the gas filler neck/tube so I would say no to vandalism. I use shell premium in all my beemers.

I think the issue was that the spark plug tube was leaking for a long time before we got the car. I believe the oil crud buildup on the valve is what caused this. I could be wrong though. It’s a shame she was running so good up until the misfire started.
