Tailgate Liftgate Problem

[atreidy]

For these few days, my trunk hasn't been closing properly using the button on the bottom of the liftgate.

Symptoms:
1) The liftgate doesn't seem to open all the way when using any of the buttons to open it. I think this is the case because after finished opening, I can manually push the liftgate about 2-3 inches higher.

2) When I push the button under the liftgate, the liftgate closes down about 3-5 inches, then seems to stop and returns up 1 inch.

3) Hear a bunch of clicking sounds like something is actuating but no results

Observations:
4) I noticed that there is a little rectangular black plastic piece that pulls off in the center of the bottom of the liftgate. If you pull it off, a bowden cable is revealed and it seems like some sort of emergency release for the trunk. Not 100% sure. But I've pulled it out and tugged on the cable before and it is no longer taut. I don't remember if it was taut the first time I pulled on it either. Wonder if I have to do anything to return it to original. It is item 12 here on realoem: http://realoem.com/bmw/showparts.do?...56&hg=41&fg=60

Please help if anyone has had similar experiences and figured out what was wrong

Also, where is the "motor" located in the automatic liftgate?

Thanks

1) did you check the height adjustment via idrive? There's 5 levels I believe.

2) when you say closes down, does it click as if it's completely closed then come back up? Or is it returning up while still in mid-air? If it's the latter, something is certainly wrong. If it closes then comes back up, usually the bottom tailgate is not slammed shut enough or something is in the way.

Sorry don't know anything about the other questions.
