Can i fit the front LED in my Audi TT 08 model? does it affect the car warranty?

i've been told that they can't be fit since the engineers has no instructions from Audi germany about that while i saw them in the new RS TT 2010 originally fitted.Can i fit the front LED in my Audi TT 08 model? does it affect the car warranty?If you change the car from what it came with from the factory you will void the warranty for that component or any other component that the new part affects. For example, changing the headlight would not affect your transmission warranty, but if you had a problem with a module that controls the headlights, audi could argue that the new headlight burnt out the module
