Any Thoughts

Cam deviation value limits are +/- 6 degrees; if you are really reading +25 degrees on bank number one (at idle, VarioCam not activated), you have a problem as the cam seems stuck in the advanced position.

The # 1 bank camshaft deviation is +25.0, and when I activate the variocam it seems to be actuating due to the idle fluctuates up and down. Which almost stalls the engine. If the camshaft is stuck in the advance position how do I correct that?

Could the camshaft position sensor cause this? How can I test that?
