Preparation for AU

Hi, I have to go to the AU 11/05 and wonder if I can check certain things myself or examine them before I can detect any defects and fix them before the AU. At the HU it’s not a problem, you can see many things (e.g. rust, brake pads down, oil cut off from the engine, cross handlebar bearings, …………………..) But what can you look at in front of the AU? And I don’t know in which condition the exhaust gases are in my car. r AU should pay attention to getting through better if you’re just at the border with something? For example, Original ESD reassembly instead of Sport ESD, check bells again (that’s all close to the exhaust system), new spark plugs + oil + possibly refuel a little better spritz before, drive engine before nice warm, ….? Or does all this have no influence on it and you can’t check anything before? The problem is, I don’t know if I come through the AU or not or where I can get through the AU. and I don’t want to fail. What if you fail? Is that the same as with HU with a follow-up within 1 month? mfg
