I happened to take car ('07 E92 335i) to dealership for alignment and transmission top up ( I had under-filled by 1.5 liters) and courtesy look over, and now my INPA, DIS or ISTA are not able to recognize or connect to my transmission! All my diagnostic software were working fine before the visit.

They must have updated the transmission software, otherwise the car runs fine. Any ideas What to do?

If they updated to a newer TCU flash file that is not in your native tools set up, you'll have to find out what it is and include it into various folders.
