Having problems with your 2004 BMW 5 Series ?
My 2004 BMW 525i won't start (no clicking, slight humm)
\015 My 2004 BMW 525i won't start. I hear a slight humm, but no clicking. All the head lights, dash lights, stereo, and indicators work fine. I connected battery cables to my 2008 Highlander and it still won't start. I drove over 350 miles yesterday (145 miles ea. way) with no issues.\015
Sounds like battery or bad starter
Starter motor solenoid problem by the sounds of it, check the connections are clean and secure, give it a tap with a soft head mallet or hammer handle. If it doesn't spring back into life it will need replacing.
