Picked up car this morning with the recall complete.
No noticable change in the way the car runs.
The worksheet says they replaced: 1 EGR valve, 1 O-ring, and 1 Rubber seal.
The only thing worth mentioning is how nice the new 2012 328i loaner was. They have finally got the transmission right. That 8 speed is silky smooth. The turbo hooked up to the 4 banger was giving me adequate performance when needed along with 35 mpg. One leg I babied it and got 43 mpg. I don't think I could get used to the engine shutting down at every stop. You can turn that feature off but you have to remember to do it.
