I hear the ticking/grinding noise when I unlock the car. My kids heard it today when we were emptying the trunk after we drove it so the valve tronic must run again shortly after the car is turned off as well as before.
I have the extended warranty so I'll take it into the shop and update everyone on what they decided to do.

just an update, dealer saw the codes, unplugged the valvetronic motor, cleaned out the plug and reset the codes. kept the car overnight and the codes didnt come back after being driven 70km and a couple cold starts. So far so good, even with a few WOT pulls.
i had the valve cover gasket replaced a couple weeks ago so i am not sure if they maybe knocked it loose then but i did get saddled with the diagnostic bill as no parts were replaced
