I just posted similar. I have an '05 530i doing the same. Turn the key to start and get nothing. Foot on brake,,, checked trans in park,,, battery shows 13+,,, computer shows nothing wrong.
Anybody any ideas?

1. Start button (obvious, but happens)

2. Integrated Voltage Supply Module (IVM) is going bad (fairly common, cheap part)

3. Brake interlock going bad (also cheap)

If you're having battery voltage issues, you'll typcally get a iDrive warning with it. I'd have someone look at the IVM.

One other thing you may want to do is have someone with a scanner check if you have fault code A111. In such a case, locate the IBS connector X13895 (3-pin connector with 2 wires, white/blue and gray wires); disconnect the connector and try restarting. If it then starts the IBS is faulty and must be replaced.
