Rollei 6008 AF Upgrade

[wexlermd]

For you 6008 AF owners, I was informed by Rollei repair that an upgrade to the AF was made ~9-12 months ago (this question, therefore, only affects relatively new owners). Does anyone know how to test one's own AF to determine if it already has the upgrade? Rollei-USA repair mentioned it to me but it was difficult to understand how to check for it.
Thanks,
Dr. Arnold Wexler

would you happen to know what that upgrade exactly improves?
