Question drivetrain malfunction

2 days before my scheduled appointment to take care of the water pump recall i got the error "drivetrain malfunction". i had just started the car in a grocery store parking lot to go home when it came up. i turned it off, waited a minute then restarted, everything ok.

for the last several months it has been occasionally hard to start, hesitant and jerking with taking off and horribly jerky in sport and sport+ mode. i have constantly voiced my concern with service dept and they say "according to bmw north america its normal".

so now with the drivetrain malfunction they finally listened. they have changed all 8 fuel injectors and it still drives rough. they are now changing the turbo o-rings. will these repairs fix the problem?

its a 2010 750Li with around 35000 miles, dont know exactly, but under the amount alloted for the lease agreement which is 45000. oh and it is a lease and they will be getting it back in january of 2013.
