Well I've finally got my Mac Pro back from the Apple authorised repair shop, they couldn't find anything wrong with it.
But Bluetooth was definitely still not working properly, so I swapped the antenna leads myself. And now Bluetooth seems to be working properly. Though the Wi-Fi signal still seems a bit weak.
