So I just bought a used 2009 Audi A4 B8, as I was test driving I couldn't see the MPH on the dash screen instead it was the gas tank range, but I figured I could change that in the settings later. After I got the car I was playing around and researching and I realized that was actually an option the orignal buyer did not opt for?!?!?!?

I was kinda mad, but I guess this is the beginning to a whole new modding journey. Any ways, I found a wiper stalk from a salvaged car with the appropriate buttons needed to change the DIS settings (I have a red DIS by the way and I have no idea if this changes things), now I am assuming that I also need a vag com connector thing to code in some new stuff too. Once I get my wiper stalk could anyone help me code this so I can have something that really shouldn't have been an option in the first place?

FYI I have only had the car for 3 days so I am super new to vag com and a lot of other Audi things so please bare with me.
