Replacing injectors on a 2014 TDI VW Passat

2014 Passat TDI. I had a check engine light pop, investigated with my code reader and found something I didn't really like. Code indicated cylinder 3 injector was failing so I figured since I was going to be into it that I would replace all 4. At the time of this repair the car has about 120k miles on it.

I sourced the injectors from https://vw.oempartsonline.com
All other required parts are from https://www.idparts.com
