I've got the balance belt tension to 3.5 using the porsche tool 9201.

At that tension if I have 0.5mm clearance between the idle roller and the belt below it there is almost 2mm of clearance between the idle roller and the belt above it, which it should deflect up to 1mm.

The only way I would get the proper clearances above and below the idle roller is to adjust the tension roller so the left side of the belt sits lower, but if I do that the belt tension is way out of spec.

Unless there's something I'm missing, it seems I have to choose between which clearance is more important, the 0.5mm below the idle roller or to touch the belt above it.
