Hey i needed some help in resolving my codes for my 2001 AWW Jetta 1.8t. I currently have 2, p0411 (secondary injection system incorrect flow) and a p0304(cylinder 4 misfire). Im pretty sure the second one has to deal with the coils, which is the cylinder 4 the one farthest to the left right? and the first one I have no idea what that could be. One of my hoses (the s-shaped hose hooked to the pressure regulator valve) is ripped, not entirely but is cracked open. could that have to do with the p0411? I would appreciate it if you would help out, Thanks!
