2004 Cayenne Turbo keep shows tailgate is open

Recommended Posts

04 Cayenne Turbo, The dash is show a car with tailgate in RED while im driving, it will keep Beep every time i take off from a stop, it is very annoying. I did make sure the glass and the tailgate are closed. anyone know this RED trunk dash message is for the glass or the tailgate? it must be a broken sensor that i want find it to adjust or unplug it or short it out in the meantime while im looking for a new trunk sensor to replace.

You can try adjusting the latch catch itself.  But this will only work temporarily.




The sensor itself is for the Glass and located right under where the glass latches physically.  The sensor is normally open, so what that means is you can just unplug it and it will think it's always closed.  This is what i did since the sensor is not easily replaced and is apart of the latch assembly.


get inside and close the hatch.  then get to work pulling the plastic off by the window ( i think the sides have to at least be loosened for the bottom plastic frame to be removed)  you will see a little micro switch in the center below the glass, it will have a 2 prong plug.  unplug that.


Good Luck.

I was surprised that I got this red tailgate picture and warning beep - all it was ...the dog blanket in the back caught in the latch area. It didn't even seem enough to stop the tailgate from closing all of the way but clearly enough to make the sensor think the gate was not shut. A minor latch adjustment might solve your problem. Also check inside the latch area to make sure nothing has dropped through the sprung trapdoor around the latch

I have a 2008 Cayenne GTS doing the same thing.  At weird times, the alarm will suddenly go off.  When I look at the dash on the car,  the indicator shows that the rear hatch is open.  Despite opening and reclosing the hatch, the dash warning and interior lamps will not go off.  Also, when I attempt to drive the car with this fault, I get the constant and irritating beeping whenever I start forward and periodically during driving.  It is strange that this only does this periodically, but I am unable to clear it.  There is nothing caught in the latch assembly or blocking the rear door from closing fully.


Does anyone have any ideas?


The 1/2/2016 12:56PM Clarksongli reply posting above contains pictures that are not viewable, so I can't determine if the post is able to help my issue...
