Mgoff5000 is suggesting that you watch that torsion value in engine block 4 column 4 (the same one you read the 0.0 value from) while driving or revving the engine. The value sometimes changes slightly (0.5 degree) with rpm. If it changes from 0 to 0.5 or -0.5, it means your belt is timed perfectly. If it doesn't change, then the test is inconclusive, and I would try nudging the cam physically:
You don't take the gear off or move it a whole notch. Leave the belt in place and loosen the 3 sprocket bolts. With a ratchet you can CAREFULLY turn the cam by the center bolt just a hair (a degree). It wont move easily/smoothly and you wont get much precision. You might try putting the ratchet on and hitting it lightly with your palm. It is an iterative process of bumping it a hair, retightening bolts, then check what VCDS says.
And take a look at this, there is a video at the end too:
