Sounds like your cam phasers. Common problem on these engines.

Thanks….I was thinking that as well…it isn’t my car…i replaced all 8 injectors about a year ago, and it sat for 18 months before I got my hands on it with the fuel system exposed…the owner drives it a lot as well

Try a running compression test. I have seen burnt valves cause that exact scenario. Compression test checked out ok, but a running compression test showed signs of a burnt valve. Symptoms were missfire at idle and smooth under load.

You should get 5 volts from pin 3 with the KOEO. Also, you should not have power on the ground wire.

I have seen an ignition switch cause problems like that on a jetta i worked on…headlights would work till i released the parking brake…the headlights would go off and parking brake light was half illuminated…so it could be the ignition switch…i doubt one light socket would cause that problem…you need to see what is common between the two then go from there.
