How do they work? are they the highbeam function on the M? and can dealer turn this option on?

The DRL's are operated through the high beams, not only on the M's. They're supplied a low wattage (2.5V) from the LCM to be on when the ignition is on, and yes the dealer can turn them on/off.

if you have bi-xenons than your high beams are your xenons, hence bi, the DRL's are only used for DRL and flashing oncoming trafic

Your dealer or someone with a GT1 can program your car to have or not have DRL
Bixenons work by raising a flap when you lock out the high beam function on your stalk:

Bixenon do not affect flash to pass - your inner "high" beam units, those are still in affect when you pull the stalk towards you.

DRL functions at 1/2 (6V) voltage - which is generally between 25-35W output - for the standard 55W H7 bulbs in your high beams.
