2013 GLI with 2.0T CBFA engine, has new timing chain with all correct parts. Sets code P0016. All marks are correct (I've done probably 20-30 chains before without any problems), and it looked like nobody worked on the car before (so I kinda exclude the possible wrong install/indexing for the crank gear). Moving piston 1 up (screwdriver is spark plug method) shows correct position of camshaft marks. Any idea where to start? Or what most probable?
It's apart now and I would like to check mechanical stuff before I put it all together and check field 93.
Thanks

Oil Control Valve will be the first thing I am checking in the morning. I know the oil screen was good. But I didn't know that oil control valve can come apart (and maybe send pieces in the VVT sprocket). Any more ideas? Thank you again

I found the problem. Front timing marks looked good. But the camshaft "dent" on intake was advanced. I moved it back with the 18mm wrench and it moved and locked in place. I suspect debris (maybe previous oil screen) is inside the VVT vanes. I will replace camshaft along with oil control valve and bridge. Lesson to be learned: visual inspection of the indentations on camshafts is highly recommend it. Thank you all
