Decoding 8S4 and 5AP

In modern US-spec BMW vehicles, two options are decoded / disabled:
8S4 Decoding for variable light distribution (VLD)
5AP Decoding for no-dazzle high-beam assistance, or glare-free high beam assistance (GFHBA)

For vehicles with adaptive front lighting using Bi-Xenon or LED, VLD can be enabled. On a F87 M2 and a F30 335i, the following codes enable VLD:
  3073 LaMaster 1, FC
    Funktionen
      LUT_FLC_FORWARDLIGHTING_Y - F020_mit_AFS
      C_AFS_ENA = F020_enable

For vehicles with adaptive front lighting using LED and high-beam assistance (required), GFHBA can be enabled. On an F87 M2 and F30 335i, the following codes enable GFHBA:
FEM_BODY or FEM_01
  3073 LaMaster 1, FC
    Funktionen
      C_HBA_ENA = F020_enable
For vehicles with Bi-Xenon additional coding may be required, eg C_HBA_ADAPT_SHUT_ENA.
