Z4 Fuse Descriptions?

[proboner]

Curious if anyone knows the actual component/system for each fuse in the fuse box? Was diagnosing something earlier today and decided to look over all my fuses and found that I'm missing a few that seem potentially required and some that are just a head scratcher. The fact that they're all related to small pictures instead of actual descriptions, doesn't help. Specifically I'm missing:

Fuse 2- which is OBD related? OBD Still seems to work fine...
Fuse 5- Appears to be related to ABS/TCS and the steering wheel? I'm manual, so maybe it's for paddle shifters, which is why it's missing?
Fuse 18- No clue what this pertains to, it's an outlined black rectangle
Fuse 54- Guessing not important for me, maybe some BMW wifi service or something?
Fuse 64 and 65- Looks like a little gear or trigger wheel? both are missing for me
Fuse 69- Looks like it's related to the stereo, but as far as I can tell my stereo is working fine. I'm guessing it's for a higher trim model that has an extra amp or something?
Fuse 87- looks like it's temperature related

Need to cross check it with TIS wiring diagrams…that’s how I worked out how to tap in extra power take offs

F2 is part of power distribution for junction box, F74 is for obd.
F5 Steering wheel heater, Steering column switch center
F18 DAB, Video module
F54 Alarm and their sensors in doors
F64 F65 Gear indicator lightning
F69 Amplifier
F87 Electric coolant pump

Also i think, that individuals shouldnt just poke around with fuses without understanding its meaning and without knowledge to find such info.

THanks for the info! Where did you get this?

TIS

Also if you understand what to look - you can see if pin/connector for the fuse is wired in junction module at their socked and fuse should be present for your vehicle order or just an empty socket.
