My S3 registered Nov 2016 and is facelift and has the LED headlights. They’re very good. LED was standard on facelift models but I’m not sure if that was just S3. Let me find my brochure....
EDIT: According to my brochure and judging by your photo, yours looks to be an A3 “black edition” which is the same specification as an S-line. So yep, LED headlights were standard on your model. As standard you would have had:
18” alloys
Black styling pack
Privacy glass
Black door mirrors
Audi sound system
Sport suspension
LED headlights with LED dynamic rear indicators
S-line body styling
Front sport seats with S logo
Aluminium inlays
LED interior light pack
Flat bottomed steering wheel
Illuminated door trims with S logo
Storage pack
That’s not an exhaustive list because the brochure says you get all the other stuff that the A3 Sport would have had, and the sport has all the stuff that the SE model has etc...you get the picture.
