not sure on the difference but my new mirrors have a blue tinted glass in them and my old ones have like an orange glass and are both heated and auto dimming ect. hope all the conections are there for the new mirrors, also the trims with audi quattro sport on them look very nice indeed and a nice touch i think to when you open the doors i will post pictures when its all done, you can have my glass when i change them over if you pm me your address ect and we can go from there
