Looks like there's a bit of excessive wear on the outer edge of that belt ok. Likely coming from the edge of the drive pulley, suggesting that the belt is indeed not running onto/off it true.

Presumably your oil level is ok and the oil warning light goes out instantly when you start the engine?

I wouldn't worry about using them, i'm sure they're fine, but i'd want to see them running true and straight whatever the cause. You can imagine if the edge has been worn like that in 10 mins, they would soon deteriorate with full-on use.

I once had the outer lip (press fit ring) come off the outer drive pulley, coupled with a tensioner bearing failure (possible cause) the end result was the outer 10% of the belt shredding itself while eating half way through the horizontal belt cover. ‘02 M620ie.

Oil pressure is good, so assume top pulleys are lined up with engine running, most likely suspect at this point is non-OEM (eBay) tensioners.

The problem was the aftermarket mobile tensioners, you can see some photos in this thread, i will refund them and buy OEM,

Good to know this for future reference - about spurious tensioners. And, it's always wise to check new belts/tensioners etc shortly after fitting.
Would be good to hear an update when you get sorted with new tension pulleys. Were you able to check the suspect pulleys to see how badly (or not) they were off?

From a local producer in Italy. He said that these tensioners are more robust than OEM and have 3 years guarantee but too bad that didnt fit...
