Did you check fuse of right TMS module? I encountered this when changing F82 M4 new headlight and new TMS module.. new TMS cannot be read in ESYS and ISTA. Turns out the fuse was blown.
Replaced with new 7.5A fuse and voila it now appears in ESYS and ISTA and was able to initialize it. Problem solved.
