Hey everyone...

Can someone tell me what this option is on the Rs4? I have circled it in the attached picture.

And if i dont have it on my Rs4 can this be easily added? I actually like how it looks on the car!

Note: Pic was found online, apologies in advance to the owner for using it

Isn't that the adaptive cruise control radar?

[MJ_RS4]

Correct, it’s for the adaptive radar cruise control,which (oddly in my opinion) only exists on the right hand side of the car..

A retro fit job seems expensive for such a mod. I like how looks and not bad to have

[Covkiller]

Wrong
It's a missile launcher

That is the one option my car doesn't have, but when I asked about it being retrofitted with the existing cruise control, the price of this 'radar' made it cost prohibitive. Whether it was a case of Audi not wanting to do the work, I'm not sure......
