Sometimes hanging a note from the rear view mirror(or taping a note to the dashboard) so the tech see's it when he works on your car - is an even better way to make sure - your wishes are followed.
This works well for when you do not want your car washed at the dealership. Sometimes the SA forgets to tell the guy who actually works on your car or ends up washing it.

I have the surging problem and hesitation off idle; otherwise, the cars runs just fine.

IF you get the "wastegate fix" the SW update could kill your engine's throttle response. Your dealer needs to make sure that you do not want the WG fix. ie: you don't mind noisy injectors and WG's.
Has anyone contacted BMW regarding 29.2 and lag?

FYI -paying out of pocket(out of warranty) for a SW update runs about one to two hours labor at most dealers. For N55 guys the PPK sw is out on the web. You only need the ODBII cable to flash your car to a PPK sw. For N54's... no one has released or uploaded the PPK sw yet for N54's.
