Hi, i'm new to this forum and was wondering if someone could help me out. I have a 00 avant 2.8 that is giving the codes codes p1411 and p1423, I am checking the combi valves, and the hoses connected to them, and was wondering where they are supposed to run to? Right now they don't run to anything, here is a photo. I'm completely new to this, so sorry if this is a stupid question, just trying to figure out if it is something else before I replace the combi valves. Thanks in advance.
