I must have asked the SA 10 times (we talked a lot over the 3+ weeks they were correcting the problem) about preventing the buildup and he never mentioned the new EGR. I tend to put 20 - 25k miles a year on my cars and would love to keep this one a while.

If it's any consulation, most SA's have no idea what they are talking about. Becoming an SA requires no special training, so unless you have a reason to put a lot of stock in what your SA is telling you, don't.
I am not sure anyone can convince you the new EGR replacement/reprogamming will correct the issue - it's still to new of a fix. May I suggest contacting BMW NA regarding the EGR campaign and your recent carbon build-up problem. Explain to them you and others shared your experience here on E90Post. Inquire about the EGR recall/reprogramming and whether it should solve the problem The representative know you intend to share their response here on E90Post. Good luck to you and whatever you decide.
