Ok, Just got mine back from dealer. The software patch fixed the throttle lag as expected. just feel like my loaner 2011 E90 335xi and very pleased!

For the wind noise, they did multiple test drive and could reproduce abnormal noise coming from both front side window. Found SIB 51-31-11, ordered and installed both parts 51337205594 and 51337205593. but they thought it fixed only 70% of noise.

Finally, they called BMW and found one more parts missing which secure seals and mirror base tightly but the parts is only available in Germany. It is coming soon.

I'll update it once everything is done!

One more thing i noticed, my mpg has been increased from 18.5 to 21.3mpg on the way back to home. (90% hwy)
