I even showed him a document I printed out. He told me that it's not needed because the brakes on the E90 are not high performance brakes. So I didn't do it.
Regardless, can you bed in the brakes at any time? Even after 3500 miles? Aren't they bedded in already from regular driving?
I didn't think they would need it either, but it made a difference in mine... night and day difference. My car has 18k on the odometer, so I think you can do this at any time. Only thing I can figure is these brakes get a film build up on the pads and/or rotors unless they are properly heated up from time to time. Keep in mind I'm no expert!
