Finally got my first BMW car, an '04 545i Sport, and was able to diagnose and fix my first issue with the help of this forum and some great folks who shared their knowledge. Was getting Dynamic Drive error and radio drops outs, and am back in business after installing a new alternator Friday evening with your DIY help. Looking forward to returning the favor soon.
Happy trails.

 

glad the forum has been helpful to you. good luck with the E60 =)
