Lunotto si apre da solo e ulteriori problemi elettrici

Purtroppo il lunotto non ha aperture di emergenza quindi sblocco via software in conce

Certo che i tuoi problemi sono strani... sembra tu abbia qualcosa in cortocircuito o qualche altro problema in contemporanea...

insomma i problemi di DSC non dovrebbero essere imputabili ai cavi della cerniera ed a macchina spenta e chiavi disinserite dovresti aver disattivato l'impianto elettrico

Ma il lavoro chi te lo ha fatto?

 

Soluzione trovata

Non si sa mai possa servire ad altri, quindi lo posto!!! Mi sono spulciato tutti i forum della serie 5, ho finalmente trovato il modo per sbloccare in automatico il lunotto posteriore.. un ragazzo ha postato anche le foto con spiegazione impeccabile! :sbav:

I might be a little late to the game on this, but I found a solution to opening the tailgate glass. First, thanks to frost for the pics he posted. I too got stuck trying to remove the plastic trim because of the two screws that you can only get to with the window open (see frost's orginal picture, it's number 2) The Bentley manual doesn't even mention them, a real help there. Anyway, I ended up, accidentally, breaking them off, or more precisely tearing through them. Turns out to not be a big deal, they still kind of work when I reassembled it.

At this point I have the trim panel off, but I still can't get the window open and I don't feel like tearing into the wiring to energize the latch mechanism. So I'm at work trying to kill some time searching the forums for an answer, thinking surely there must be a manual release, right? I find this post: http://www.bmwland.co.uk/forums/viewtopic.php?f=5&t=105599 and the last post has what I have been looking for the mythical manual release. I get home and look around at the latch for a second to figure it out, and there is an oval shaped hole, down in the hole you can see some metal and the metal has a round hole in it. I put a small screwdriver in the round hole and the whole metal piece slid up and "pop" the glass was open.

The first picture below is looking at the latch if you are standing at the left rear corner of the car. The second picture is a close up of the latch and inside the red circle is the manual release mechanism.





Now with the glass open I can test the actual switch for continuity. What do you know, it's not the switch, so I'm thinking it's the wiring in the hinge. I close everything up for the night, trim is still completely disassembled, and for the fun of it I try the glass switch...and it releases I'm thinking WTF, I try it a few more times and every time it works. I'm not going to complain and I can go to bed happy.

Next day, it still works and I put the rear hatch back together glad the whole ordeal is over with, but with everything reassembled the switch has quit working again.

Back off with all the trim, except for the main trim panel. I removed all the screws/fasteners except the two hidden under the glass. Now for the test (frost I hope you don't mind that I borrowed your picture, but it's perfect for this explanation)

Once you have the trim panel at the same point as picture 1 below, it's possible to use a long slender tool to get to the manual release. I pulled the left half of the trim down and used a 18 inch flathead screw driver in one hand and a small flashlight in the other(to see what I was doing)to pop the latch. The longer the tool the easier it will be because there's not much room to get your hand, much less your arm, in there. Just in case you're thinking of using something like a straightened coat-hanger, don't, it is not rigid enough to pop the latch.



The only thing I can figure out is maybe with the trim panels removed it took some strain of the wires and the switch would work. That's the only thing I can think of anybody have any other thoughts? Since then the temps have dropped into the teens and 20s and I don't care that much about the problem to brave the frigid weather, but will have a look once it warms up a little. Another strange thing, when the tailgate is open (the whole thing) I can't use the remote to unlock or lock the car doors.

Ecco, ora non mi resta che mettermi all'opera!
