It may well be correct.
The worldwide semiconductor (computer chip) shortages are impacting pretty much all motor manufacturers as computer chips are an integral component part in all modern cars. The chip shortages have meant that many car manufacturers have temporarily shut down production lines and / or assembly workers are working reduced hours, so fewer cars are being built.
I’ve read on some of the VW forums of lead times of 9-10 months or longer for certain models of the current Golf.
If you do a Google search on ‘semiconductor shortage and impact on the motor industry’ or similar search, you’ll find more information on this issue.
