Unhappy Turbo Noise / Rough Idle / Engine Dies

My 2011 535i has started having a few issues, I'm wondering if anyone has experienced any of this:

1) Turbo used to be a lot more quiet, you can now hear the turbo spool up very loudly, no matter if the windows are closed / open. You can here it throughout acceleration and during gear changes. Is this normal? Anyone else seeing this? I'm barely at 12,000 miles, it started at around 11,000 (that or I never noticed).

2) Engine has "died" in sharp turns, the RPM is usually sitting at 500 - 600, and then just dies. Dealer has said there has been no codes, so there's nothing they can do about it. I have a 6-speed MT, and it was always on neutral when this happens. It has happened four times now.

3) The car shakes a lot during idle, and when turned off it's pretty rough. Whole car shakes, a few test cars I've driver have never done this.. It's just very rough.

4) There is a slight rattle at low speeds, seems to be coming from passenger side. Almost always happen during low (1000 - 2000) RPMs on 1 - 4th gear.

Am I just over-reacting? Has anyone else seen / experienced these issues? Any advice?
