2004 Jetta 1.8 Turbo VLI -- Two engine codes. P0011 and p0030. Idling rough, like a misfire, but apparently not a misfire. Please help diagnose issues. Don't know anything about the p0011, and I've tried to test the upstream o2 sensor for battery voltage, and I'm only getting about between 2.5 and 3.5 volts... but I don't know if I'm doing it right. I place the red lead from my multimeter in each of the pin slots, and then my black lead against the heat shield of the catalytic converter. Some pin slots read in the millivolts, and others read in the range I just mentioned. Nothing reads battery voltage, unless I'm doing it wrong. Wires look fine on the connectors. Help me through necessary tests to properly diagnose both codes. Thank you.

Hello, my name is ***** ***** thank you for using just answer. I would start with the p0011 first, as it relates to camshaft timing. I recommend you check the cam to crank timing with the marks, as well as the condition of the timing belt.. If thats ok, I then reccomend checking the marks between the camshafts, by removing the valve cover.

Okay, I will start there. Could you send me instructions for how to do those things, please?

You there?

The upper part of the picture is the cam sprocket, you must remove the upper timing shield on the passenger side of the engine. The lower part is an image of the harmonic balancer, which is on the bottom. When you have the upper timing cover off, this is also a good time to inspect the belt condition. These engines are known for premature timing belt failure due to a failure in the tensioner, thanks.

  1. Stephen you do have something to do with timing .
  2. The upper timing cover needs to be removed and the rf wheel removed with the side shield.
  3. you need to set the timing up like the pics attached especially at the crankshaft to reference the cam to see if the timing is out.
  4. now did the timing belt break or was changed recently?

thanks

I'll check. Don't think the timing belt has ever been changed.
Customer reply replied 1 month ago
Is this an interference or non-interference engine?
VW Mechanic: Wolfgang, VW Master Technician replied 1 month ago

interference big time!!!

if the belt is spot on then the valve cover needs to be removed . let me know when the cover is removed for the next step

Will do. My brother in law has the car for a another week out of town, so I'll shave c to wait until then to do the check, if it doesn't blow up in the meantime. Don't worry, I always rate people, and I will you when this is done. Thx.
Customer reply replied 1 month ago
You know, please forgive my ignorance here, but is there like a step-by-step process you can give me for exactly how to test or adjust the timing? I know I've got the picture that shows the things lined up, but I don't know exactly how to get to that point, or make any adjustments if it's not lined up, Etc.
