What do they do during the 1200 break in service?

I bought my M3 used with 30k on it, so I never had to worry about the break in service.

I imagine a break in service as a super early oil change, what else do they do?

From the "Service and Warranty Information" booklet:


1200 Mile Service
The engine in your BMW M3 is a race-bred
engine design which includes increased power
output and maximum engine speeds compared
to conventional BMW 3 Series engines. The
increased power output also affects other major
drivetrain components such as the transmission
and the rear axle differential. The 1200 Mile Ser-
vice requires changing the oil in the engine, as
well as in the transmission and the differential.
The engine air cleaner element must also be
replaced during this service.



Note that the transmission fluid change is only for manuals, the M-DCT fluid is lifetime. Also, engine redline is kept very low during break-in: 4500rpm, if I remember correctly.
