@lightbody : Hi. Yes, @langers2k is almost 100% correct (because there is no "probably" in his/her assertion)!!.

If you think about how DRL lamps are designed, there is no need to add cut-off characteristics into their reflector designs (more correctly called "luminairs") because they operate in daylight when dazzling effects don't happen. Also, because DRLs compete with daylight, the design objective of the fittings is to get as much light as possible into the front of the car.

Both of these factors are antithetical to illumination during night-time!! So, and in answer to your question, the DRLs are switched-off, or they are dimmed substantially when the Low-beam lights are illuminated. This should also happen when the Parking Light (Side Lights) position is selected (often the dimmed DRL is used as the actual Parking Light).

Yes, they are reduced in brightness, when the low beam is switched on.

Thank you both for the clarifications. So in conclusion, the car does not have an equivalent of what in the UK we called "side lights", and the only lighting at the front of the car that is suitable after daylight is dipped beams.

I actually just nipped out in the car - today is an overcast but actually quite nice day in Glasgow - and it was nagging for me to turn on dipped beam...

Not so, "side lights" are still fitted but turning only them on is less than intuitive.

If it's the same on the Golf 7/7.5 as on my Octavia if you turn the light switch to off instead of Auto then the DRLs don't come on, and if you turn the light switch to the position after Auto then the side lights turn on but not the DRLs.

@lightbody: Just to add a concluding comment to @PetrolDave response - on MQB platform cars the difference between how the associated lamps for Parking-Light/Side -Light works is determined exclusively by the the 2 x Leuchte-commands ;

Standlicht allgemein (Schlusslicht; Positionslicht; Begrenzungslicht) =Parking lights in general (tail light; position light; parking light)
Standlicht vorn (Positionslicht; Begrenzungslicht)=Parking light (position light; position light)

If 1 is used in a Lichtfunktion channel, the lamp will illuminate whenever the LDS is NOT set on 0 position (i.e. the LDS is set on AUTO (and night-time), PL (2 x opposing lights symbol) and Low-Beam positions)

If 2 is used in a Lichtfunktion channel, the lamp will illuminate only when the LDS is on the PL (2 x opposing lights symbol) position

LDS (ignore "Fog-lights off" in picture)
