What I am saying is that typically when new PSdZData comes out, you just update your PSdZData, as we have all done many times over the last year. This will continue as usual, until your Token validity expires. However, if at some future time during your year of validity, BMW changes the security measures, well yes, of course an updated patch / token will be required.
