Hello friends, today I did diagnostics on my A4 B9 3.0tdi and the errors from the attached photos came out. I can't find anything specific about them on the internet, and I'm hoping someone here can help me figure out what these errors are, where to look for the problem, and how to fix it..I also want to ask what does this mean from the last picture and is it related to the headlights, it won't let me enter the modules as well as the 46 module, it says no communication with the module, what could be stopped. Thanks in advance friends

Hello colleagues, I have a case study and I am asking for help... It is about Audi A4 B9 2017 3.0tdi 272hp. I decided to service the engine properly, camshafts, chains, connecting rods and main bearings all OEM plus new bolts. There was no problem with all the parts except the main bearings and this is where the need for help comes in. No one knows which bearings to order, no one knows what color the car left the factory, some say they measure the shaft, others say they measure the bearings, others say they measure the clearance between the shaft and the bearing, and now once a week we can't order these bearings. What I found out is that they originally come in 4 colors and opposite each one there are dimensions but are they mm or clearance. No one tells or knows what we should look at, what we should measure and how and how to navigate which bearings to order. ... Please advise and help thanks Good night
