Case closed : story from Korea.
So, I was digging into this issue for a while, for my father-in-law's 09 750Li.
After 3 attempts to fix, months in the service facility, it looks like it's been solved.
I wanted to share this case with all bimmer fans/owners.
He was having vibrating/little sputtering issue especially on load, around 2000~or so rpm range. (about 100km/h of vehicle speed)
He complained, and put the car in, each time, it looked like that the problem is been solved, but it came on again in days for twice.
Third time, bmw guys assumed that it's from fuel injection, they tried hard to pick the one failing.
At the end, they couldn't pick just one out of 8, they just replaced all 8 injectors,
the symtom is gone!
(At least it's not on for weeks yet)
Finally, my father in law can drive his 7 with pride..
So, if you are having similar issue with others suffering, I am strongly recommend to take the car to the dealer and have them replace all the fuel injectors
EVEN IF there is no fault code.. Computor/Scanners cannot see through everything.
Don't let them go around until the warranty ends.
It's their responsibility to try everything they can do at whatever cost.
Especially for $200,000 car. (their asking price in Korea)
