This is the mechanical A/C belt tensioner used on the 2001-2006 E46 M3, MZ3 S54, and Z4M. The tensioner keeps the A/C belt at the proper tension for driving the A/C compressor. A failing tensioner will allow the belt to loosen or slip resulting in diminished performance.

This part is listed by BMW as BMW part number 11281433571 (11-28-1-433-571) and is described as Genuine BMW Tensioner Assembly for AC Belt.
