I understand the theory of how it's supposed to work, but you haven't provided any evidence that it does what you say it does. Do you have any proof that it has successfully prevented an aux belt from taking out a timing belt on a D5? I'm not having a dig at you here. I'm trying to acertain whether this is a theoretical idea that is still unproven, or a legitimate fully functional and approved method for timing belt protection.
