Servotronic Replacement difficulties.
 

So I removed my steering rack successfully (absolute pain), and I found my hydraulic oil leak and it was the servotronic case cover. I can't find a new rack with the servotronic and I don't really know if theres a possible replacement not directly made by Audi or bosch or that's an original, like a newer one. Any places I could find one? Or a rack with one included?
