Any thoughts on N55 left sitting
So I left my 2016 435i gran coupe sitting for a couple of weeks when I was away at work. First time I fired it up, it seemed like it stuttered a bit, then a few miles down the road I got a drivetrain malfunction alarm, loss of power, and the car shook when I applied the gas. I googled the symptoms and it said maybe bad plugs or ignition coils, try letting it sit turned off for 5 to 10 minutes. The charge pipe is fine.
I left it overnight and then the next day when I tried it, the thing ran perfectly. I put it in Sport+ and drive it hard for a little bit and everything is fine.
Did it just need a good run? Fouled plug(s) maybe? I'm hoping that's it and I'm good but any thoughts works be appreciated. Cheers
