Hi everyone
You probably are not aware that ADU cambelt must be positioned out of the set mark on the cam pulley....
Don't tell me i'm crazy...
This is due to a different waterpump pulley compared to the ABY motor instead of setting a new/dedicated mark on the cam pulley Audi went for a "out of mark" set....
The issue it's well known on the RS2 fans world here you can see the "correct" setting:
Off set has to be just and only on the cam pulley the rest has to be put onmark!
