Already drained the radiator hose up front but wasn't sure if there was another plug as illustrated on the 5 series when I googled m57. Was getting frustrated. I went to the dealership few blocks from me and the guy on the parts department doesn't even know what it's for. LOL
Thank the "gods of DIY" I prayed for an immediate answer, and you responded!

i guess it's all drained then if it's just the hose.
