BlueTooth related questions (all BT questions go in this thread only)

Hi All - appears to be an older thread but title states ALL BT related posts to be posted here hence (hopefully) reviving it...

My wife has 2011 VW Tiguan which came factory fitted with RNS 510 navigation unit and 7P6 035 730 B module under the driver's seat.

This has worked flawlessly until about 2 months ago when telephone stopped working but everything else (navigation, media via CD, SD card, HDD, MDI) still OK. When starting vehicle, the MFD immediately shows "Phone name" Connecting user but never connects and there's no longer a BT option under media.

I've since unpaired her phone (from the phone side) but cannot get it, or any other phone, even her old phone still listed paired as a media device, to connect.

I have tried to restore the telephone to factory settings using the Setup menu on the display but get message "Factory setting not reloaded". I've also disconnected (unplugged) the module under the seat to try and reset it but no luck. Even left it unplugged for more than a month as, the moment it's plugged in, it again tries to connect to my wife's phone and will then stay on this screen until one hits "cancel", only to reappear a few minutes later again, which can be quite annoying.

Using a mates scan tool (handheld unit) an error code appears under 0019 Gateway 01303 Telephone Transceiver. The same code appeared under Radio (I think 0056) as well as telephone (0077). Once we cleared these, the fault remains under 0019 Gateway whereas both Radio and Telephone now display no faults but issue remains.

Any thoughts appreciated but seems as if the BT function has stopped and not sure if it's part of the unit beneath the seat? If unplugged, the telephone option disappears from the setup menu, but as soon as it's plugged in again, telephone option displays again. So seems the head-unit can see the unit under the seat but BT is not working and one cannot restore factory settings.
