My car misfired on the way home from work yesterday, I pulled over and scanned the codes and it was cylinder 4. Thought it may be my coils since i had changed my plugs ~4k miles ago and idk if the coils were ever changed by the previous owners, so I swapped the coils from cylinder 3 and 4. Took it for ~20-minute drive on the freeway and street and the misfire did not occur. Any idea what the issue could have been? I have a 2hr trip coming up in a couple of days and don't want to risk the misfire coming back on the drive there.

Bump, drove for a while again today, no misfire still

It's more than likely the coil packs. Change them. If they are going out the they will have spotty misfires.

Literally had the same thing happen to me the other day on my car. Cylinder 1 had a misfire, next day no issues.

Change them because I guarantee you on that 2 hour trip, that Coil pack will be shot.

When one goes, it's a good sign that the rest of them aren't far behind.

Did that this morning before my trip, car was fine before changing coils, and after i installed new coils the misfire came back, on cylinder 4 again. Was unable to troubleshoot as i had about 5 minutes to spare, ended up having to drive my moms car. Have high doubts my spark plugs are bad, like i said they only have around 5k miles and are the factory standard plugs from fcp euro, also my car isnt boosted yet. Any idea what the issue is? Read online that it may be the fuel injectors but my car only has around 83k miles so it seems extremely early for my fuel injectors to go.

Codes im getting are:
2EE0-Combustion misfiring, several cylinders: Fuel Injection Deactivation.
2EED-Combustion misfiring, cylinder 4: Fuel injection deactivation.
2EFE-Misfire, several cylinders: Damaging to catalytic converter or damaging exhaust gas.
2F02-Misfire, cylinder 4: Damaging to catalytic converter or damaging exhaust gas.

N55

In my experience N55's rarely have injector issues but they often have misfires. I would change the plugs again with dealer plugs or NGK's gapped correctly. My friend with an N55 and I have both put brand new plugs in (Bosch) and had immediate misfires. Of course it could be injectors, carbon buildup, coils, etc. but that's where I would start.

I thought I read that you changed your spark plugs

That would be the next step. And get the right plugs. OEM pregapped. Super important.

If it's not the plugs, then it's the fuel injector since you already did compression test.

Im going thru kind of the same thing
I have a n55 335i with these codes
2BC0 fuel-air mixture too lean
2FAB ignition, cylinder 4 combustion period too short
2EFE combustion misfires several cylinders detected
2F02 combustion misfire cylinder 4 detected
2EE0 misfire, several cylinders: fuel injection deactivation
2EED misfire cylinder 4: fuel injection deactivation
2774 air mass plausibility air mass too high
The car us on mhd stage 2 plugs and coils have less than a 2k miles on them
Colder plugs and upgraded coils
Would it he the injectors?
I didnt go with a really known coils brand its called trq coils but the car’s boost target is around 16.1 and its only going up to 8-9 psi with no engine lights not limp mode

Did you ever find a solution to your codes as I am having the same issues and exact same codes as you posted. Thanks in advance for your help.
