Reading Insignia 2011 suspension errors

Hello. I have 2011 Insignia 2.0 CDTI EcoFlex which has a "Service Suspension System" Error on the dash. From what I have researched I cannot read those errors and the suspension module with the Chinese clone of the OP-COME because the communication is done through CH-CAN. I have tried several shops with different scan tools and in only one with original GM MDI were able to read the error (one of the suspension sensors or the wiring causes the problem). I want to be able to read those kind of errors and modules by myself so I am searching for a tool that I can do that with. So the questions are - Are the original OP-COM and original GM MDI are the only tools that can communicate with this module? Or I can buy GM MDI clone (and from where) or something like THINKGDIAG 2. Or there is even cheaper alternative?

THINKDIAG 2 will be ok. i read with launch so You can also do it.

clone of mdi or scanmatik 2pro or scanmatik3 + gds2
