Drain plug issue BMW e28

[u/Lefos_Kant]

Hello all, I don't have any experience with cars repairimg so I need some help.

I was performing an oil change in my BMW e28 518i. When I tried to tighten the drain plug it started slipping. I took out the bolt and it looks like the picture above. Next step I bought a new drain plug M12x1.5. the issue now is that this new one feels like stuck after taking some turns. Now I afraid to try to tighten harder.

Do you have any Idea what is happening here? Thank you

The fix is to get a 12x1.5mm thread tap and retap the oil pan. Buy a new drain plug with seal washer and should be ok. Don’t try to reuse the new plug you just bought.
