A good example is using the AE Halo lamps as DRLs - this cannot be "coded" as such but the Resler/iBus or Bluebus units are able to activate this "feature" via a datagram or message via the appropriate bus.

I think the mirrors folding on ignition is like this - the Resler/iBus unit is sending the same datagram or message (command) as would be sent when you press the mirror fold button but there is no coding option to activate this "feature".
