Txs JFP. Truly a great contributor here. Dug around some more on the threads and started to piece together some info and replies from you on other threads.
For those landing on this thread, here are some helpful links on how to do this:

Testing / Camshaft Position Deviation Specification / Wear:
Your cam deviation specs are +/- +6 degrees at idle; if your engine is at 11 & 15 degrees (cam deviation values) you have a more mechanical issue as your cam timing is way out of whack. As you car is a 2000, it is a five chain motor, meaning that it has an extra set of cam tensioning paddles between the two cams (note the small chain connecting the two cams with the green arrows, about half way between the two green arrows you can see the wear pad of the five chain tensioner):
The small wear pads can literally fall apart, throwing the cam timing off (these are worn pads next to new ones):
I would suggest rescanning the car, looking at the cam deviation values at idle
When these pad get beat, the cam deviation values go way out of spec, and the car throws the code you are seeing. You would also find small yellow/brown plastic bits worn off the pads in both your oil filter and sump. If the sump contains green plastic bits, they would be coming from the VarioCam unit itself, which can also do this, but is much less common than the chain paddles. While you are rescanning the car, also activate the VarioCam solenoids one at a time at idle; you should hear a pronounced click, followed by a major movement in the cam timing, along with a big change in how the car idles; this will show you if the VarioCam solenoids and the units themselves are functional.
You definitely have a timing problem, as your can deviation values are way out of spec at idle, which is before the VarioCam does anything. This is most likely the tensioner wear pad issue. Your VarioCam system is not activating on bank 2 (cam angle does not jump to over 20 degrees), so either the solenoid or the VarioCam unit itself is out. Did you hear the "click" I mentioned when you activated the VarioCam on bank 2? If not, I would start with that solenoid.
In any case, you need to get to the source of the out of spec cam deviation values; your timing is far enough out that you could get into serious trouble if it moves further. This is going to require pulling cam covers to inspect the wear pads, which will need special cam holding tooling (the cam cover forms one half of the cam bearings, so a holding tool in needed to keep from potentially snapping the cam in half when the covers are removed).
