There is definitely a new Weber code key were are not aware of. I have run into another VG model Q2200. VG is also showing on the Weber.com schematic/manual download page at https://www.weber.com/US/en/help/manuals/. Note the VG in the dropdown box.
I've had reports from owners in Germany and The Netherlands of Genesis II EP-335 with GBS and Spirit E-330 Premium with GBS grills with VW date codes on grills purchased in 2020. Also, another EP-335 in Germany with a VG date code for a grill purchased in 2021.
It's got me rethinking GIVEJOYNUW.
Weber.com says these are valid codes: GE, GI, GJ, GN, GO, GU, GV, GY, VW, and VG.
I think it's actually GVIEJOYNUW. That fits with the reports I've been hearing about for VW and VG grills. So 2022 grills should be VV and 2023 grills should be VI.
