Hi David and Helen,
I also have had similar news and worries, I ordered mine in June 2020 and was told to expected it in February or March 2021. It then was extended to August 2021 and the only excuse from VW Germany was shortages in sourcing semi conductor micro chips.
The story was that supplies from China and Japan where the micro chips come from are taking longer than usual due to COVID 19 related issues. Factory closed, factories running at half the personnel and finally a factory had caught fire had cause a major back lock of supply. What can one do, so I just keep waiting. In August not having any news from them I went down to see them in September. To my surprise they offered me the deposit back as they cannot commit or confirm a build date. Now October 2022 has been said and I suppose it is to keep we away until then. VW Germany will not tell us anything else and by the look of things they are not to worried with lose of business.
