any help is appreciated in pinpointing my issue.
how do i bypass the n112 valves? just remove them and connect the hoses with clamps? or how?You could always bypass the n112 valves for a couple of weeks and see. If I undrstand things correctly and the n112s are the issue, it should cause the combis to be open all the time and if everything else is working, the CEL should go out after something like 8 cold starts. If not, the combis are likely seized closed.
