Yeah vanos could definitely be a problem, but it would also throw codes for timing related issues, but since all cylinders on bank 2 show low compression I would assume maybe even a loose chain gear sprocket since there is no pin to guide them gears with the cams there isn't anything that can hold them other but the pressure of the torqued bolt that holds it.
