Hey guys,
I have a 2013 F30 X-drive with 58k miles
When accelerating I can notice a stutter in the acceleration of the car. Almost as if its losing power or not getting enough fuel.
I have read and know of the issues of our LPFP's\injectors.
My question is, how do I know that this is the actual issue, since I get no light/codes. I just did spark plugs to rule that out.
Also, can I upgrade to a stage 2 even though all i'm running is jb4/chargepipe/intake? or is that only if you have higher mods. Should I just upgrade the pump to the latest walbro?

I also have a 2013 F30 X-drive that has recently started hesitating during acceleration. I've noticed that it's almost imperceptible when I first start it up in the morning but is much more noticeable after the car warms up on my way to work(30 minute drive). I've suspected everything from clogged fuel injectors, clogged air filter, bad gasoline, transfer case failure, software issues, broken charge pipe, bad spark plugs and finally broken turbo. I've been able to rule some of these out but I need to make an appointment with my dealership to get it diagnosed because it's really bothering me. Maybe we can figure this out at the same time! I'll update my progress.

Probably a long shot but, have you tried cleaning the Mass Air Flow Sensor? How many miles are on both your cars?

I have been meaning to do that as well! I will definitely rule that out today.

What about walnut blasting for oil buildup. I've read other posts that the N55's didn't have this problem (only the N54's) but, others say the N55 does have this problem just not as bad as the N54. Maybe someone can chime in and offer some info.

Sorry, not yet. A new development tho, in the morning when it's cold outside and the engine is cold, the hesitations are not present. As the engine warms up, they come back. Maybe a bad mass airflow sensor? It's going to the dealership the 1st week of December, I'll update when I find out.

keep us posted!

I used some MAF cleaner. I want to say it greatly improved the situation, with very little hesitation after. But has come back slowly since.
