The heater is for cold fuel, definitely not for drying the fuel. From "BMW Advanced Diesel Technology" (factory handbook):

The fuel heater only works with the ignition switched on and when
both of the following conditions are fulfilled:
Temperature drops below a defined value
A defined fuel delivery pressure is exceeded due to cold,
viscous fuel.
So, as can be seen, no mention of "Drying" but definitely a mention of cold fuel.
