Hi! 
I have recently retrofitted NBT EVO and changed TCB1 to ATM in black box. I have done adapter plug, routed new Oabr twisted pair and GPS antenna from EVO to ATM because I don’t have blue plug in HU. 

Evo works perfectly. I could flash it and activate new FSCs. But I can’t communicate with ATM. I don’t see it in esys and ISTA. 
BUT somehow GPS is working, and I was able to activate WLAN hotspot via iDrive menu. Also my microphone is working but very quiet. There is of course SOS failure on dash. 
I tried to connect another ATM (I had only white, roof version to test) using my adapter to make sure my wiring is ok and it worked fine. I could see it on diagnostics and esys was able to code it. 

Is it just cooked ATM or its common issue? It seems ATM is working but it can’t log into CAN. Is it fixable?
