I am sorry that you have not been helped yet. I just came online and saw your question

Ok, I need you to go ahead and list all fault codes coming up.

I also need you to use your scan tool to try to communicate with each control module and tell me which ones it will not communicate with.

And list any work done immediately before all these issues popped up

The more detail you can provide, the better I can help

Do you now where the control modules are located in the car? I have found one under passengers seat and one under the air conditiong system, but there are more. Do you now?Is it enough to disconnect the contact clamp on each control module and then find the one that not want to communicate?Idont have my fault codes here right now, you can get it later.

I use a scan tool to communicate with the control modules. You need a full function scan tool such as the Snap On Solus. My software is locked up right now, but will post diagrams of each control module location as soon as I get my software going
