My E90 just started making some belt noises last night, I opened the hood this morning to find that the belt tensioner is slowly walking the drive belt right off. I figured I'd try to tighten the tensioner back on a bit after re-setting the belt in place only to find that my belt tensioner has no way to tighten the bolt. It's got a flat surface where the aluminum torx bolt should be. Now I'm wondering if this is too dangerous to drive to the shop tomorrow because I'm worried the belt will remove itself from the crooked tensioner and damage something. Has anyone seen something like this?
