Your Audi doesn't really have any sensors per say that would cause shaking. The only sensor attached to your caliper is your ABS and that can be ripped out and thrown away and you won't shake. It sounds to me that your rotors are definitely warped. Get some new rotors and pads and I wouldn't imagine you will feel anything else.
