Here's a pic that might help, it's labelled A96. Quite easy to get to, the part no. is 61357199997 for the later version. There are older versions but it seems the later ones are backwards compatible. Might not be cheap though
. Take a look on Realoem for the different part nos. https://www.realoem.com/bmw/enUS/pa..._30i&mg=61&sg=25&diagId=61_1625&q=61357199997
