Crankcase Ventilation hose failure
Got this CEL with mods: PS2 turbo, charge pipe, meth, JB4+, Wagner intercooler, DV+. Seen this on other forums but none on 16 OG M2 with mods. Any advice please? Car runs fine otherwise

However if it really has to do with the pcv hose, then in most likelihood the brittle plastic hose has cracked. It is very common especially after heat cycling for awhile, and it could have cracked. Since these cars can measure vacuum it probably detected a leak in the crankcase caused by your faulty hose and triggered the cel. Just open the hood and feel the pcv hose by gently squeezing it. If it feels firm then it's ok check the connections if they're secure, if it feels like it's crunching around or brittle like a bunch of broken pasta noodles the hose body is broken and you'll need to replace it. Make sure you feel the entire length of the hose from the valve cover to the intake inlet pipe, and do it when the car is cold if you don't want to burn yourself.

Also check if your oil cap is loose that could be contributing to vacuum leaks in the crank case, since the car detects vacuum leaks from the crank case and always suspects the pcv system to be the issue and not the oil cap (since they expect that to be tighten when the car is running.

Just saw a stg 2 turbo install and if ur using the pure inlet there's a screw for the PCV pipe that didn't work for the tech working on the car I saw. He zip tied the pcv and made sure the o ring was on securely. That could be ur problem. See where the hose connects to the inlet pipe close to the rad fan.
