Just got my 2007 550i with 27K miles back from the dealer. I had the jerky transmission, rough downshift from 2-1. I got this done - http://www.bmwtis.com/tsb/bulletins/bullet...mp/B240309g.htm.
Observations:
- 2-1 transmission slam is gone.
- overall the car feels more responsive and the transmission just feels like its in the right gear. it used to feel like it was in the wrong gear half the time.
- MPG: no change, 18.5 for me.
- I must have got a comprehensive SW update as the font on my heads up display looks different as do the colors on I-Drive.
Also had my sunroof seal taken care of (was noisy) and my door seals quieted (they added some tape or something).
