It is quite difficult to get information on the exact changes between different MY ID4s for the UK, especially interior trim, but I have gauged the following from many websites.
Please add useful stuff or info links
MY21 - release model
MY22 - from 1 Sep 2021 - enhanced spec - no information on changes
MY22.5 - from 1 Dec 2022 - interior drops the brown trim on dashboard and pockets for dark grey and black
MY23 - all get 12” screen
MY24 - new screen controls with “lit up” volume and temperature controls
