Replacement DIM works - but all other problems still there.

Thinking of just pulling CEM and sending it in...

OK - FIXED!

MoVolvos - THANK YOU for recommending Yagger. Guy is a genius - bottom line, I would not have gotten this fixed without him - VERY GOOD GUY.

Ended up being a bad CCM (Climate Control Module) - it's signal corrupted the entire low speed CAN BUS network which fouled dash, radio, locks, windows, sunroof, dome lights and caused all kinds of communication problems between other modules as per VIDA. Very interesting how one bad module can lead to soooooo many things going haywire.

Learned a lot through this, including how to use an oscilloscope and saved a TON of $ - dealer would have had a field day with this one.

Thank you to everyone and this forum!
