I have a 2015 crua style engine and can’t find anything on where certain things go after deleting. For instance, on pre turbo where egr was before does that get plugged or left open and also coolant lines and what not. I can’t find much info on this at all on the web all it shows are older cars pre 2015. Help please

Remember...you MUST tune.
If not the extra fuel will still be injected for Regen...and go out the tailpipe...at best eye watering at worst will melt your bumper or worse.
This will also act as a bit of a bump!
Good luck

I did get the tune done no lights on starts right up but going down the road when turbo starts building boost it sounds like it’s struggling like trying to suck air where it’s plugged off at where old rubber elbow went on egr cooler. I’m wondering what happens if I leave off the silicone plug they sent with kit. I was guessing it went there cause I see nowhere else for it to go

If you change or delete anything you must use a professional tune or you will get codes.
ok, I am in the middle of upgrade on my 2015 Golf TDI CRUA 6speed manual: CP3, CR190, EGR/DPF delete, quafie differential, and south bend stage 3 clutch.
There are several vendors for tunes, do your research for which is best for you and your application.
I am using TuneZilla for my application. Review their web site, it has a lot of information. If you are unsure, find a local dealer and discussing what you are looking for/trying to perform.

Yes, for the 2015 TDIs they are a one year only and there is not a lot of information and some miss information, but that means you have to dig a little harder and look for clues.
