what is going on!

hey guys, i have a 2014 jetta tdi that’s lately not been wanting to start up properly. I’ve gotten a new battery about a year ago, and just recently a new manifold, egr valve replacement, new glow plugs, and fuel pump. My CEL is on still which is in turn causing my car not to regenerate to make the DPF light go off. This is a video I took today trying to start it. Any help would be great thanks!
