Audi A4 19td 130

Hi, I'm new to this. If I don't answer something, it's because I have no idea. I have to wait for my daughter to help me. The thing is, I need to change all four shock absorbers and I don't know how. If you could send me pictures, I'd appreciate it. The car is an Audi A4 1.9 TDI 130hp, model year 2000-2004. Cheers, and I'll learn as I go.
