A couple things that may help. INPA or BMW specific software can force the fan on at whatever percentage you request, I.e. 20% or 100% etc. My Foxwell NT520 can do it and my laptop with INPA. Good for fan diagnostics.

Also, the LCI X5s (facelift like yours) have this dumb variable valving on the AC compressor. So just because you push the AC button, doesnt necessarily mean the fan will come on. Threw me for a loop the first time i realized that..
