Low RPM shake diagnosis

My 2011 750ix has a shudder when accelerating from 1200-1800 RPM. It feels exactly what it used to feel like in a manual transmission when you are in too high a gear and try to accelerate. I have seen this mentioned in other posts but never as a stand alone thread and haven't really seen any resolutions. Has anyone had this successfully diagnosed and fixed? I have already had the CCP completed and had hoped it would make this go away but it didn't. I had all the standard CCP items replaced except the timing belt. I am afraid they are going to say either they could not duplicate or that this is just the way it drives. It drives me nuts. Thanks in advance!

I've noticed my 740i does this sometimes during cold start around 900-1200 rpm's slight shake/stutter but it doesn't throw any codes or affect anything once driving. Id like to know if this is something I should look into as well

I've heard this before, sort of a drivetrain shudder? Was told it's common on the X-drive and can't be fixed.

EDIT: Because it's not "broken"

Update:
Dealer said one of the rims is bent. That may be true but I don't think it's what I am feeling on accel. Anyway no codes so I'll see what rim straightener guy has to say about it.
