Cheers guys...Looks like I was getting confused with dynamic light assist which we don't have in the UK:
Right then, from the Golf 7 Self Study Manual SSP517 - Golf 7 Electrical
Bi Xenon Headlights (with LED DRL's) - as fitted to UK GTI and GTD Models

Technical features
The bi-xenon headlight with dynamic cornering light (AFS, Advanced Front lighting System) features a daytime running light in a continuous U-shaped chain of 18 LEDs around the D3S xenon bulb.
The brightness of the LEDs is regulated according to the function being used (daytime running light or dipped beam).
The LED unit has been designed so that the entire LED chain is switched off in the unlikely event than one of the LEDs fails.
The power consumed by the LED chain when the driving lights are on totals approx. 4.4 watts (dimmed activation) and approx. 8.5 watts when the daytime running lights are on.
Bi Xenon Headlights (with LED DRL's) and DLA (Dynamic Light Assist)

Technical features
The dynamic light assist (DLA) incorporates the dynamic cornering light (AFS) and dynamic main beam control (MDF) functions.
The layout of the bulbs and the appearance of the bi-xenon headlight with advanced front lighting system (AFS) and dynamic main beam control (MDF) is the same as that of the bi-xenon headlight with AFS.
The design of the inside of this bi-xenon headlight is, however, different. It features a group of individually moveable screens which can be swivelled into the light cone cast by the main beam lamp.
The dynamic main beam control function, that is, the partial masking of certain areas of illumination, is implemented through a combination of the screens and the horizontal adjustment of the module.
Hope this helps ?
