Mein Auto: '08 535xi & '02 X5
Belt tensioners have springs (or hyrdraulic). My 02 x5 needed these. I identified by using long screw drive held handle to ear tip to non moving part close too tensioner. Yes while car is running. Be careful. There is stethoscope for this but I don't have one in my TBox.
