Just picked up my 1st E55 yesterday!
Set your dash to read outside temp, turn key to position 1, then press the reset button 3 quick times, scroll through the menu (on the dash with steering wheel buttons) select dyno mode. Turn key off. Theres also a video on YouTube.

But if it works, how cool is that?

That being said, if this is really how you enter "dyno mode" then how do you exit it?
Thanks!
