Do a search on "eccentric shaft". There's a huge thread about it floating around. There's a seal that fails and let's oil into the sensor which screws it up causing those valvetronic error codes. The op of that thread had almost the same issues you had. Eventually the car will have almost zero power. I have no experience with this myself but others in this section have.
