BTW, I always heard that you should never change the direction of a belt after installing it (and like many things automotive, this advice was given with no explanation). Did not make sense to me until I figured it would be this groove potential issue where after a while the belt's ribs either survive or not (or wear to accommodate) in the grooves it's got and makes it work. But if flipping, all bets are off. Anyone know if that's right or other factors are involved in that never-flip directions advice?

You can file off the rough edge of the wp pulley and flip the belt. If the problem doesn't come back you found the problem and can replace the belt.

You can also try those laser pulley alignment tool. It magnetically attaches to the pullies and points a laser to check if the grooves align.

If there is no alignment option not sure if that helps just confirms you are screwed :-)

On my M62 I ate two belts. Turned out the indie who replaced my water pump (I was far from home and needed it done) did somethings screwy. Never figured our exactly what, but the pulley was slightly out of alignment causing the belts to go pretty quickly. It was hard to tell just by visual. You needed a straight edge to see the misalignment.
