Hey 👋🏻, so I picked up a used 2020 540i M sport about two weeks ago. The day I get home from the dealer I see there’s a crack on the drivers side mirror cap. Annoyed, but my fault for not realizing it before I Left the lot or I would’ve negotiated a bit more. Nevertheless, I ordered the mirror cap from getbmwparts and I went to just line it up and realized it’s actually not the mirror cap at all and is the arm that swings below it. My question is does anyone have a part number for that specific area? Do I have to buy the whole Mirror assembly!? Really didn’t want to spend $700 on the part. Photos attached and any info is appreciated. TIA
