Hi. Building my r32 mk4 back and have several issues when plugged in.

*01314 (ecm) no communication
*01316 ( brake control module) no communication.
*01321 ( air bag module) no communication.
*01336 (combination comfort databus) no communication.

Any ideas what it could be causing all these no communications.
The main ecu is plugged in correctly.

Also i have 2 plugs im not sure what they connect to. One wire is really thick. Looks like its coming from scuttle panel area. Picture attached.

Also 3 plugs that would be near the oil filter.

thanks in advance
