Helping a friend with LED headlight retrofit on 2014 F15 but I'm having some issues.

We went from adaptive Xenon to adaptive LED. Made the appropriate wiring changes and did the following coding:

Updated VO:
- Removed 522 (Xenon)
- Added 552 (Adaptive LED)

VO Coded following modules with updated VO:
- Left and Right FLE
- BDC


Retrofit is successful and working well, but the old TMS modules are still visible in ISTA. Receiving a no communication error with STM (which theoretically makes sense since they are no longer in the car?)

Have you written "updated VO" and new VCM to the car???

With adaptive LED headlight you should have communication with both the LHM (FLE) as well as the TMS. you have 2 units per headlight (1x LHM and 1x TMS), so 4 units in total and all 4 need to be coded. Check your wiring again and make sure you get communication and power to the TMS modules.
