Mein Auto: 2011 550xi
Is there any way to tell if you have the most recent update?

I have a late May/2011 build 550xi that experiences really sluggish acceloration in the 5-20mph range about 50% of the time. Sounds similar to what I have read here, sluggish start and feels like it has 2-4 big stutters until the turbos kick in in-full.

I plan to take it to the dealer, and I would like to give them the specific update to check for.
