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 ?

Thanks for that mate, very helpful! So it looks like the UK have to do without the active headlights then!  

I hope the static cornering lights can be turned off with VCDS.  They look a bit daft to me if I see them as I'm walking/driving along - like the car has broken fog light.

I'm not a fan of DRLs either - that was the first thing I turned off on my Mark VI.

The mk7 doesn't use the fogs as cornering lights so you probably won't see them anyway.

Actually it does.... The centre light between the bi-xenon and the parking led comes on below speeds of 10km/h. It's an H7 light as you can see in the picture and it is definitely active in mine as you can see in this video:

The reason I've resurrected this thread is that the yellow colour of the cornering lights is annoying me compared to the white light of the xenons, so I've just ordered a set of blue H7s.

I'm skipping to the end here so apologies if this has already been answered but is the orange glow in the cluster from the bulb or from the cluster itself, ie. Can I buy a chrome coated indicator bulb to get rid of it?

I had a look at this, it's a clear bulb with an orange plastic lens so nothing you can do about the orange in the headlamp.

Well that's a shame but never mind, thanks jimble

Whilst on the subject, is the H7 a horrible yellow bulb and will it need replacing with an Mtec or does it already match the xenon?

Standard H7 is quite yellow, swapped mine out for Osram Nightbreaker plus.

I see thanks for the quick reply, i always like cosmos blue over the osrams, i know its not a good example but you can see how nice the mtec is here http://www.e90post.com/forums/showthread.php?t=138890
