2002 tdi 1.9 diesel 5spd jetta..... I was replacing a bunch of broken and worn hoses from solenoids when i was replacing my egr valve. And cleaned out the egr cooler. Runs great now. But this code p0412 2nd dairy air injection circuit. Malfunction.... Didnt have any codes before.... I may have put new vacuum line hose in wrong places. .. Any pics out there for this ciruit. And which solenoid is the one that runs this?
