Will a 2011 M3 OEM alternator fit in a 2012 M3? They seem to be identical in dimensions. Any input is appreciated.
You should always purchase parts by vin number. BMW loves to switch parts mid year to give you the shaft. You can't just ask for a 2012 alternator and expect it to fit.

2011-2013 M3 with ZCP have an improved EDC + DSC software. There was a BMW press release article reference on the improved EDC (not to confuse with euro MDM). They re-optimized how the EDC uses DSC data to dynamically adapt the damper setting in sport mode. This is no speculation.

"With a suspension lowered by some 10 mm and light alloy wheels in the size 9 x 19 inches at the front and Y-spoke design at the rear, the Competition Package provides further optimised longitudinal and transverse dynamics. In addition, the control of the electronic damper adjustment function EDC including a Sport mode specially developed for the Competition Package has been precisely adjusted to the chassis modifications by means of map-based control and the driving stability control function DSC."

I am sure there are other 'silent' minor improvements in the last year that the marketing team did not publish.
