I didn't need to reset anything - the check control error cleared down and I left the lights on with a battery charger connected while putting everything back together. I'll scan the LCM later today and clear down the shadow codes, I'm assuming all is well.

There is a TSB on this which is all I can add right now:
====================
SI B 63 07 05
Lights
April 2006
Technical Service

This Service Information bulletin supersedes S.I. B63 07 05 dated November 2005.

[NEW] designates changes to this revision

SUBJECT
Headlight(s) are Inoperative After Parts Replacement or Coding

MODEL
E46 (3 Series) with SA 522 (Xenon lights)
E53 (X5) with SA 522 (Xenon lights)
[NEW] E83 (X3) with SA522 (Xenon lights)
[NEW] E85 (Z4) with SA522 (Xenon lights)

SITUATION
After replacing a headlight(s) assembly, Lamp Module (LCM), Lamp Switch Center (LSZ), Stepper Motor Controller (SMC), Active Headlight Control (AHL) or coding the LCM/LSZ the headlight is inoperative.

CAUSE
The System has not been initialized.

PROCEDURE
The headlight has to have a calibration sweep in order for the LCM/LSZ to recognize it.

Use the following procedure to calibrate the headlights:
^ Select - Control Module Function Screen
^ Select - Active Headlight Control (AHL)
^ Select - Activate Components
^ Select - Reference run with senior
^ Select - Control module reset

====================
This looks to me to be forcibly 'reminding' the LCM of the state it should be in.
