i recently bought a 1999 golf gti vr6. i am a newcomer to vw's, recently joined this website and found it very useful to solve why it was setting the p0411 code (in the end it was a blown fuse, vacuum lines are all ok and in good condition, SAI pump is ok too). once i replaced the blown 5 amp fuse behind the battery, the car ran fine until couple seconds of letting it run, it started making an arc-ing/missfire noise. when i get back to work tomorrow i plan on scanning it and looking for a missfire. if it is a missfire i plan on changing plugs and wires (if necessary coil), but if it isnt a missfire, worst case scenario, what could i be looking into? i also read that a rattle type sound could be caused by the shifter rod near the intake.
