HBA (High Beam Assistant) - USA spec high beams that turn off in the presence of headlights or taillights of other cars and automatically turns the high beams on if no other cars are present.
GFHB (Glare Free High Beams) - European spec high beams that enable your car to keep the high beams on without blinding other cars. This is basically a better and more advanced version of HBA.
European cars get VLD and GFHB standard and us Canadians and Americans have it coded out. All we get is HBA if we chose to get the exec pack. Many people here choose to code VLD and/or GFHB back in themselves because they're really cool features to have even though they're technically not legal.
While GFHB is debatably a safety hazard, VLD is most definitely not so people code it back in all of the time.
Variable Light Distribution has several different modes of operation (for Low Beam):
1 - City Light: Shallow and Very Wide Beam Pattern active from 0 - 50kph (30MPH) (Both Headlamps are Panned outwards 12 horizontal from center and 0.7 lowered vertically)
2 - Standard Light: Same Basic Beam Pattern as with 8S4 Enabled and Headlamp Switch Set to Auto. Active from 50 - 110kph (30MPH - 68MPH)
3 - Guiding Fog Light - Shallow and Wider Beam Pattern Enabled with the Front Fog Lamps On and Headlamp Switch in Auto and Speed 0 - 110kph (Both headlamps are panned outwards 8 horizontal from center and lowered 0.7 vertically)
4 - Highway Light - Long Throw Pattern illuminating approx. 25% further than Standard Light. Active from 110 to 250kph (68MPH- 155MHP). (Driver's Side Headlamp is panned 3.5 outwards Horizontal from center and lowered 0.25 vertically, while the passenger side headlamp is raised 0.2 vertical)

Thank you for taking the time to write that! I really appreciate it. Do you know if the Bimmercode app has the ability to code in VLD?
