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.

Automatic Trunk Lid Doesn't Work

My trunk lid on my 2007 750li no longer opens and closes automatically. When I press the trunk button on my key the trunk unlocks but just sits there. I have to open and close the lid by hand. Not that that's so tough but I would like it to work the way it's supposed to. I read somewhere that it might be low on hydraulic fluid. Any suggestions?

Check the fluid, passenger side in the trunk, But if its low, i would check for leaks.

Do you hear the motor in the trunk pumping when you push the release button ?

I had exactly the same with mine and it turned out to be the gas shocks that help to lift the boot / trunk. My hydraulic level was fine it was just weak gas shocks.
If the motor is running and you can help it to open by hand then you could take a look at replacing them. It's fairly easy to do and not expensive.
