This is a genuine BMW ribbed v-belt, part number 11 28 7 636 378. You will find it under Engine (Other Engine parts). It supersedes the older number 11 28 1 437 929, so a part carrying that number is the same part.

BMW draws it on 10 drawings, among them two Belt Drive Water Pump/Alternator drawings. It weighs about 160 g (0.4 lb).
