I like them, especially in the winter.

Had them in the past and always wondered why they were there. Don't miss 'em one bit.

I just noticed this, and checked mine, and they aren't there on my S5 SB. then saw this thread. I used to find them handy in the ice/slush/snow in the winter on my A6, but yes, they were a point of failure. And as things melted after a run and using them, they would drip/melt in the garage. so I guess I'm ok with not having them. Where I live now, there wouldn't be much use for them anyways.

The reason they were included with Bi-Xenons was because of the glare that they produced. No need for it with LED headlights.

Had them on my Golf R, not sure they actually did anything other than spray liquid on the lights (which didnt clear them up)

Entirely possible Audi decided the headlights put off enough heat not to need them, not sure on that though.

LED headlights put out less heat than Xenon/Bi-Xenon, if any. All mine did was spray the hood.

While inherently true that per lumen LEDs take less power to run, there's no way of knowing for sure that the LED headlight assemblies draw less power without knowing the design specifics.

They're on the Matrix LED lights as the high-beam would blind other road users unless the light pattern is dispersed properly. If there's too much crud on the headlight lense then the theory is that the refracted beam pattern won't be correct and therefor on-coming road users could be blinded. That's the theory... how much of that actually transfers over to the real world is another matter.

The heat is still in the housing though right? or is the heatsink outside the housing?
