The m3 requires the old school break in change. BMW recommends its and pays for it.
The question is why didn't you want the same for your 335?
I'm being rhetorical. It isn't necessary but my thoughts have been if its good enough for an M....
Also don't forget those spark plugs at 45k on the 335!!! it is often missed.
