Yes, this is for your Vanos system. From what I can see, everything is working fine... The input and output are for intake and exhaust camshafts. For intake, the adjustment angle (grad) increases with % because the camshaft can only advance due to Vanos gear design. The opposite is true for the exhaust, because Vanos unit can only retard when the solenoid activates. So what you are seeing is percentage of Vanos solenoid activation (pulse width) versus camshaft movement via the camshaft sensors, the intake/exhaust adjust in opposite directions.
