I have an 07 335I MT, with 170K miles, you will need to look at all the rubber in the suspension. I did a marathon maintenance on my car this last winter. The car was down for couple of week as I fix all the oil leaks (except oil pan), clean intact ports (3rd cleaning) mind looked like yours but I walnut blasted them, changed plugs, and coils (original), change front and rear shocks, fixed various broken plastic part under the hood. I am starting to notice the suspension if getting sloppy and vibration, looks like most of the rubber is shot or very close to being toast. I would advise looking at all those parts as well.
