7 Series - E65 / E66 (2002 - 2008)
Discussion of BMW's 4th generation E65/E66 7 Series flagship. The E65 generated much controversy, due to its radical styling and iDrive user difficulties. Nonetheless, the E65 broke records to become the best-selling 7-series iteration ever, especially after its 2005 facelift.

Mein Auto: 2004 745LI - 2001 M5
04 745LI sometimes wont start-Then finally did start

I bought a BMW, a 2004 745LI with 119K miles. The car is very clean and very well maintained. One day, I got up drove to work 20 Miles from home, drove back home, changed for go to gym and went out to the car and when I pushed the Start button.... nothing. I put the key in the slot.....push the start button.... Nothing. Radio and all electronics are playing. No sign of any battery issue. I'm pushing on the brake, first firm then hard. Push start button ... hear nothing.
Go back in house, try again, and on 10th try car starts. I almost gave up, with a bad case of buyers remorse.
I drove it all day today and parked and restarted 5-6 times. with no issue, started right up.

I have no idea what was happening, but I'm guessing it might have to do with something that I'm unfamiliar with, but maybe BMW owners are aware of.

Is there something you do when you push the start button and nothing happens, what other option do I have to start the car when that happens?

Thank you.

It was quite easy to do on my 2006 e66. 20 minutes maybe.

Hi, I already order the IVM from eBay new at $100 free shipping, in the meantime is it safe if I drive the car or I should better wait until I install the new IVM?

Thank you.

It might leave you stranded. Your decision.

Oh ok I think I'll wait until I install the module.

Is this very common in BMW's?

Thank you.
