XPS 8910 Bluetooth

I had a useless hour call with the Dell hardware warranty support group about what I concluded was a defective Bluetooth component of the M.2 wireless card that shipped with the system:

Intel 3165 3165NGW 3165AC Dual Band Wireless AC + Bluetooth 4.0 Mini NGFF wifi card 802.11AC

The Bluetooth part of the card stopped working. I uninstalled the Bluetooth component, tried other drivers from Intel and used the Dell Diagnostics and Windows Bluetooth Troubleshooter. Basically the Bluetooth component could not be found.

The hardware support team could not find that a Bluetooth card was shipped with the system. They did not seem to understand that the Intel 3165 card has both a dual band wireless and Bluetooth 4.0 component. I showed them the description of the card on the Intel site but that did not sway them. Since a Bluetooth card was not on the hardware component list that shipped with the system, I did not have Bluetooth.  They  dismissed the fact that Bluetooth was working fine until recently and suggested I spend some time and money talking with the software group or erase my system and reinstall Windows. .Since I can replace the card for less than $10 I did that.

The question is whether, in fact,  this card has both functions. The wireless component works fine, a little unusual when the Bluetooth component does not.
