I think there could be some confusion here over interpretation of the English language. Forget about “facelifts” and accept that currently A2 owners on this forum are driving around in what is technically known (by Audi) as 2003 models. If any change were due in the later part of the year 2003 (actual) then I believe it would be called a 2004 model.
It may well be that the A2 Sports and the FSI are deemed by some as 2003 models – in spite of being built in the year 2002.
