Will this grille fit my car?

[MOA4B9]

I'm in a hunt for an RS style grille and found some at very good prices and I'm willing to take a chance on quality. One thing that is stopping me from buying it is the uncertainty if it will fit my car. The description states that it will fit:
for Audi A4 B9 2017-2018（Fit for B9 Models 2017-2018 ONLY）
for Audi S4 B9 2018+ （Fit for B9 Models 2018+ONLY）

I think the first B9 came out in 2016. Is there any difference in grille or bumper between 2016 and 2017+?
I've got an S-line which was registered in March 2017 but I'm not sure if it was built in 2016 or 2017? Is there a way to find out the build date? I bought it used so haven't got much detail about it.

As far as I know, theres no difference. They wouldnt redesign the way a grill fits after 1 year of production

2016 is when the model year 2017 came out, and in 2018 MY 2019 came out so looks like your car is within the range above.

Why didn't you simply read and add on to the thread that commenced in '17 thru to 3/19? T'was only a short simple search.
May already supply the info & then no need for people who have already posted to regurgitate same.
Know its an A4, but the majority of threads discuss A4/S4/RS4.

Have you asked the seller if it fits your particular A4?
