Thanks mmi. I won't pretend to know how you knew thatI see... the BCM has different part number (than T6) so VCDS has loaded another description file - which obviously isn't quite up to date.
However, there is a workaround. Just click "LCode 2" to enter into "raw" mode (all the tick boxes show up, though still undocumented) and then tick the "Bit 4". (And retick bit 6!)

Presumably puts a DRL ON/OFF selection into MFD. However, doesn't seem to work on T5/T6. There are a few mentions about this somewhere in the Forum.
