FYI, since your in europe, your probably not getting very hot summers, in which to push your Z4's S54. Although germany did have some heat waves this summer, so I wonder if you "pushed it" at the ring on one of those days.

I have an MZ4 Coupe with S54 and I've pushed it at 115º F days in the middle of summer at a grueling track like Buttonwillow (lots of slow speed turns). Oil Temp never went above 260º F.
