Nivau regulation on the rear axle 3.6l Bj 90

Hello together I am once again on the help of those instructed who know themselves !
Because with the replacements of Audi I can't get any help anymore, I am so far around the Audi I want to know someone has idea how the rivau regulation works with the V8 because I have a set of dampers that are like me for the regulation but when I have disassembled them I don't know how that should go what moves when it regulates and what must the damper look like so that it also looks like some pictures or tips would be really awesome! I thank you and wish you another good evening!
