VCDS, if you are running the latest version of software, will, if it is considered safe for a DIYer to do, offer the correct security code for a module, if it is not offering a security code when you place the curser in the correct box to enter the security code/key into, ie hovering over that box, then I'd think that VCDS if you are running the latest version of that software, has considered that logging into that module is not the best plan.
