This used OEM BMW Transmission Oil Cooler / Heat Exchanger Bracket (OEM part number 6866329) has been removed from a donor vehicle and is ready for install. Also called a heat exchanger bracket, it secures the transmission cooler to the engine bay. On the 0.6L range-extender models (i3, i3s), this bracket can crack from thermal cycling, allowing the cooler to vibrate or leak. Over time, a broken bracket may cause fluid loss or reduced cooling—replacing it restores proper heat exchanger mounting and transmission temperature regulation.
