There’s been some forum members on the Golf R forum who’ve waited around two years after placing their orders before getting their cars.
During the past three years, lead times have been impacted primarily by Covid, semiconductor supply shortages and the war in Ukraine. VW were continuing to take customer orders while being impacted by the aforementioned events, which created a sizeable backlog of unfulfilled orders, and that added to lead times for customers - especially those who have most recently placed their orders. VW’s suppliers will also have been affected by the issues listed above.
Things do seem to have been improving during 2023 - from what I’ve read elsewhere, VW appear to have ramped up production earlier this year. Also, Covid is probably having negligible - if any - impact now and I suspect semiconductor supplies are no longer a significant issue. Ukraine was a major supplier of parts / components to motor manufacturers before the war with Russia, but I dare say VW have found alternative sources for parts / components previously supplied by Ukrainian manufacturers.
There’s always chance that your indicated build date will change again, although not necessarily further into the future - it’s not unknown for dates to be brought forward as well as move out.
