I can see the rpm on my 2014 116i.
I am also trying to use an extended pid to read oil temp and pressure.
So far I have found mode 22 586F gives data but have yet to convert the A & B bytes into actual pressure. (actually I've found over 200 PIDs using Torque Scan plug-in but no way to identify what data they contain)
No luck with the oil temp so far. (the OBD mode 01 pid of 5C is not used by BMW)
This website has some extended pids. RPM is 0A5 bytes F(low byte and G high byte)
