BMW S85 engine problems and reliability
First of all pay attention to the VANOS system. Always check the temperature of it and try not to overheat it.
Also, this engine has problems with premature wear of connecting rod bearings. The interval of its replacement is about 50,000 miles (80,000 km). So, summing up, the most common problems are:
Connecting rod bearing wear
Throttle body actuator failure

Not enough?!
IMO, comparing to this our engines are rock solid
Of course after you harden the VANOS
PS: don't get me wrong. I love S85 a lot. That sound is unbelievably good. Just cannot justify for myself rebuilding it every 50k.
