i've known about the FSU problem for some time... but it just happened to my 2003 E39 this past Friday. Ordered the part from autohausaz.com this weekend and it arrived today. popped it in under 10 minutes and all is well again! cost was $52.09. thanks for an awesome BMW community that supports each other!
TIP: guys, if you're having a hard time pulling the plug off 'cause it's been there untouched for the last 9 yrs like mine, get yourself some robogrip pliers or something similar. came right off and saved my finger tips and laying in an awkward position for too long. use to do some car/mobile electronic stuff and realized using pliers to remove those plastic wire plugs made life so much better than using fingers and nails.
