TÜV failed :-(, make/make or scrap?

Hello, today had my TÜV appointment and the Audi failed with the following defects: – Service brake at the rear: effect on one side (brakes at the rear are new, possibly air in the line?) – parking brake on one side (brake ropes are new) – lever distance of the parking brake: too large (can I rearrange) – brake discs at the front: rusted (must I have to replace them for that? / cost?) – brake pads at the front right side: wear limit reached/exceededed (cost?) – steering wheel / handlebar: registration en required (Have ABE, but according to the examiner it has to be entered anyway, because I have exactly the original tire combination, but these must be original Audi rims?) – Push/track rod head: right turned out (cost?) – rear mirror matte right (I can’t see anything matte, completely dirty) – dipped light: height regulation is missing (with the front you can only adjust the height regulation by lever, TÜV inspector I mean have an automatic on it – what is not possible) – Stable Is it possible for me to lose oil (you know) If I can get the oil (you know) If I can get the oil (you know) If I can get the oil (you know) If I can get the oil (you know) If I can get the oil (you know) If I can get the oil (you know) If I can get the oil (you know) If I can get the oil (you know) if I can get the oil (you know) if I can get the oil (you know) if I can get the oil (you know) if I can get the oil (you know) if I can get the oil (you know) if I can get the oil (you know). Which I have to pay in a workshop? Bzw. Opinions whether this is worth it? Greeting Michi
