Found the issue! I found my COM port latency was at 16, switched it to 1ms. Modules were reading perfectly after. I was wondering why it would sometimes read the can layout fine, and other times it was challenging to even see all the modules.
Powerclass on the new CAS from BMW was coded to "invalid". Read the DME's power class as "00", and corrected the CAS to 00. Half check engine light came off, car had boost and drove great. Still smelled a clutch smell after a short test drive.
The VTG module was causing dsc malfunctions, so I used INPA to code the 4 digits on the transfer case to the VTG since it was having problems, I believe it was the initialization procedure, and found it had the wrong transfer case programmed as well. After the procedure ran through the clutch tests, I had no CEL or codes!
I don't know WHAT this cheap key guy did, but I'm happy to have found my solution. Customer is very grateful lol.
