OBD-II I2C Adapter on PSA vehicles

So after a while of browsing the internet and asking Peugeot/Citroën dealerships for help I figured out why my Mega kit isn't working on my '02 Peugeot 206 GTi.
Apparently PSA vehicles up to '06 do have the OBD-II connector and the Freematics adapter wil fit the J1962 (X11/22), but...
it's not running CAN but VAN (Vehicle Area Network) ISO 11519-3, the OBD-II plug actually sits after a multiplexer called BSI (Built-In Systems Interface) that'll only send several K-lines and one L-line to the plug, but all ISO9141.

I've on a hot persuit of wiring diagrams and device pin-outs at the moment, but will update if I have more information about where to find the CAN Low & High.

I hope this is helpfull to other users with PSA vehicles and myself will greatly apreciate any aditional information an the matter!!
