Hi All,

Just wondering if anyone could provide some advice on the auto open boot / trunk function.

I have a 2002 E39 touring with the auto open boot - i.e. hit the button and it goes all the way up (or used to!).

Now when I hit the button, the boot opens and I can hear the motor whirring but nothing happens. Are these systems hydraulic? Any ideas what it could be?

I can still open the boot as normal (i.e. using my arm!) but it is not doing what it is designed to, though it sounds like it is trying to...

Thanks

Chris
