Avanti

Hello, Will mats designed for the pre-facelift A4 Avant (pre 69) fit the current A4 Avant? Because I can’t see any for ‘2019 onwards’; In the item description on various websites, at best it’s listed as ‘2016-2020’ or ‘2016-2019’. I can’t find this information anywhere on line! Also, I see that each generation has a code associated with it; ‘B9’ for example. I don’t know what this means or what it is, but what would it be for a 2020 A4 Avant? I saw ‘8W’ somewhere? Thank you, A.
