Bluetooth
In a nutshell is it a case of oh yeah that’s quite common or yeah not so common but does happen or is it a case of if everything is working as it should and it’s only the Bluetooth not working then the chances of it being the Bluetooth part of the multimedia unit going down next to zero?? (Oh it’s a 2010 so not a separate module under seat job). Could a software issue/bug just stop the Bluetooth working only? It’s only that I’m in that predicament of I really could do without lobbing out £££ on either a apple carplay or buying a 2nd hand mmi unit and all the grief that goes with it (removing component protection etc) if there’s a chance it’s just maybe a silly software issue and then would I’d be better off just paying Audi to check?? As at end of the day all I’m after is the Bluetooth working so as lovely as a apple-car play probably is I don’t really need it! Thanks again!!

If you don't see anything faulted in your VCDS scan, then neither will the Audi dealer, and that's when they start making things up, like, we recommend that you NEED to replace the head unit or this control unit, etc., etc. It's definitely a learning experience if you haven't been to the Audi Stealer seeking a diagnosis/repair on electronics
If you want further reassurance, then you can go do a fiber-optic test/diagnostic using VCDS that will check to ensure everything that's connected is working properly. I don't think it'll turn anything up on your car, but you've got VCDS, and so why not run the test/diagnostic and see what comes back...it's the same thing an Audi dealer tech would do.
You've established that everything else works perfectly within your MMI/infotainment system except for getting your phone to work/synch for the hands-free calling/Bluetooth in the car.
You noted you have a significant number of faults showing up in your internal, Green Menu MMI faults/errors pics, and have you traced any of those down or tried to clear them inside the Green Menu section where those are showing up? The test/diagnose option is located one or two options above/below where you found that list of fault codes, and some of them can likely be cleared; I've done that on my own Q7 just to tidy things up. Write down the fault item #s, as you need those to pull them up in the menu where you tell the computer to PASS that item through the testing node, then you delete the fault code in same screen, then go back to see if it removed or not, etc. You can cycle through several in succession before referencing back to the 'faults' display page menu.
I know you'd like to think the Audi dealer would be able to fix this for you, but that's not really what they do; they replace expensive parts and then test to see if replacing the expensive part they sold you fixed the issue or not.
If not, then they begin again.This is simply a very difficult thing to remotely troubleshoot, as once you check the 'basics', then it is heavily 'in-the-details' of your specific car's coding and internal MMI fault messages, which is why I sent you the pics from my own Green Menu to verify if your background Car Functions menu settings are correct or not. All it takes is one errant checkmark in a sub-menu box related to hands-free or Bluetooth to make that feature not work, which would otherwise work perfectly fine, etc.
In other words, just because your Q7 has the Bluetooth for hands-free calling doesn't necessarily mean that every reference to it found in that Car functions/settings, etc., menu should be checked off...that's just not how it works. It's a shared, common system, and each car model has it's own unique coding.
