cobb P0128 code after WP & Tstat replacement

Wassup everyone,

I'm pretty new to the 1 series community, I've had mine for about 6 months and 2k miles ago had to do the water pump and thermostat replacement. I've noticed even after I replaced them I'm still getting the infamous red exclamation point on my dash and I'm getting codes P0128 and p2ef4 along with a bunch of other codes. I attached the pics. I did do the install of everything myself. Could I have possibly done something wrong. I did notice from searching around that alot of people were replacing one of the rubber hoses which I did not do. Any input would be GREATLY appreciated. I am running Cobb v3 aggressive map on the car.

Thanks!
