All sorted now, lined up as you said. Test started it and it ran perfect.
The *only* thing that concerns me is that the tensioner seems to be 'loose'. There is 1 stud which is pivots on, that even when tightened up - the tensioner (brand new) has movement on, is this normal?
On the Golf IIRC, the pivot stud is also what secures the tensioner, but on the Audi, there is a sprung mechanism that secures the tension - but the marginal play is still alarming, I've never come across this before.
Not mine, but the tensioner arrangement is the same.
