2012 TFSI 2.0t number 1 cylinder misfire only at idle, worse with cold start engine. Ruled out coil, plug, carbon on valve, fuel injector and vacuum leaks. Changed out the intake cam variable oil control plug and it stopped happening for about 5 minutes, then returned. Any help appreciated. Anyone know if the cam phaser can be removed from cam? No cam codes given on fault scan. only misfire number 1

 

What is the compression in that cylinder.

 

I got 120 psi on all 4
