Today is my last day of legal driving. We found the new vsv I bought was faulty, so I bought another one, we tested it, it works. Check engine light came back on last night, still egr. Replaced all the necessary parts, egr, modulator and vsv, new vacuum lines, everything is clean. We are truly at a loss. Maybe 02 sensor? I read about it. P0401. Never ending. This sucks.

Also make sure you re-connect the vacuum lines correctly after the installation of the new valves. It's easy to switch them around. I learned that the hard way
