Audi RS3 owner cannot release tensioner with standard 17mm socket because it broke off, and needs to know if the center Torx can be used to fully rotate the tensioner into service position for belt replacement.
Existing repair guides assume the 17mm release point is intact; no clear guidance on using the center Torx as an alternative when the primary release point breaks.
