My 2001 A6 recently picks up speed very slow after stop.
I use VAG-COM and read the following fault codes. If anyone knows where to get the brake switches and how to replace them, please help. Any advice is highly appreciated.

Try Blauparts, or pelicanparts search for brake switch. I'm not sure what those exactly are.

Also search the forum for your codes.
