I tried the old one and even a spare sensor from another set of heads and nothing

rut ro......you need to pin out the harness and hope you find it in there.you could be looking at a bad switch in the ecm or an issue with the windows in the cam.(never seen a vq cam like that,but could be)

you need to start with basics, check every ground and make sure you have no voltage drop to the ecm

list your codes.
