This is exactly what I did. How do you write FA back to the car computer?

To restore I read my backup FA xml (I diff'ed it against current with 5AP in it and no 8TL) and did what you mentioned above. I may be doing something wrong so it would be great to know how to do it correctly.
If all you have done is code ECU without writing the FA then I'd wager your OTA update was not related to the FA state.

You have different coding options than your FA indicates, but I doubt the OTA pre-req checker would know about that.

There are some codes that impact remote services so I guess that could be a possibility. I've changed codes that have prevented CD services from working, but seems unlikely and more likely a co-incidence.
