I've tried multiple obd2 scanners and none can connect to pull the codes up, they all receive power from the port but no information. I've tried the scanners on other cars and there fine. also, my eml and all other related dash light work fine.

Welcome to 2CarPros.

First, this vehicle isn't offered in the US, so I have very limited technical information, but I will try to help.

Since you have power and you know the scanner is good, the next thing you need to check is if the OBD port has ground (and on this vehicle I'm not sure of the pin location).

If you can get a schematic of the DLC, identify which pin is ground and check it for continuity to ground.

Let me know what you find.
