Cayenne_Ben or working4it, any guidance on how you solved the inability to open the hatch?
My fuse 31 is good, and when I attempt to open the hatch normally (from outside) I can see and hear the actuator arm move a bit. Through the access panel in the hatch, I can disconnect the actuator arm from the central hatch latch, and the actuator moves much further. Trying to manually move the latch mechanism only opens it part way. Not enough for the hatch to open. Something is impeding the latch.
Any guidance on if you found it was an issue with the lock mechanism on the hatch that was stopping the latch from being able to be fully released? (and if so, how'd you fix it)
I had this trouble - ended up taking it to my local specialist who opened it from the inside with some patience and tools I didn’t have. Lock replaced (broken internally).
I'm providing some guidance for the next person who runs into a Cayenne rear hatch they can no longer open.
It's awkward, but the interior panel can be removed from the inside. My issue turned out to be an upper latch (attached to the hatch) that was jammed / broken. With the interior panel off it was possible to force the upper latch open (there's also Jeff Spahn's approach above with the Rockwell cutter tool, but I just couldn't bear to try it...).
I also replaced the lower latch mechanism at the same time. It now closes with a much better oompf /authority sound as it pulls the hatch to a full close.
See the PDF for all hatch parts. I replaced the highlit items. interior of hatch
Do you see a clear indicator of what failure lead up to it? Like something lacking lubrication, binding or otherwise being subjected to something that leads to early failure like this?
Not sure which caused the other to fail. The latch in the tailgate was definitely jammed. I drove for several weeks on rough mountain roads without being able to open the tailgate or fully close it. It's been good since replacing both the latch in the hatch, as well as the lower closure motor.
Hello,
I have searched these and other Porsche forums for help on a Tailgate that would not open on a 2008 Cayenne S.
I did not find the answer directly but found some info here to help me resolve issue.
I checked the two tailgate fuses on the right and left dash fuse blocks , both were good.
Symptoms:
Power assist tailgate would not open, stayed shut. Lift motors were running and tailgate became slightly ajar ,about 1mm of play.
There were no means of opening the tailgate, not the door handle nor the button in the driver's door.
I had to open from the inside access panel.
I remove the lock actuator thinking it was the suspect part when when I tested it it worked and tested voltage to the actuator and there was none.
Anyway I read a post here with the same symptoms.
It was the #31 fuse on the right dash fuse block panel- Listed as Central locking system FILLER FLAP. 15 amp

Had these exact symptoms with our 2009 Cayenne. All fuses (including #31) were tested and were found to be okay. Manually accessing and operating the lock actuator did not allow me to the door to open. Then, after much frustration, I discovered that I could get the door open by pulling hard on the lower lip (just barely enough room to get my fingertips in there) while also actuating the unlock button on the key fob.
I am not sure what the problem is, but I am going to replace the upper lock mechanism because it is affordable and it seems likely it is the culprit.
If anyone can point me to step by step instructions (or a video) for replacing this latch I would be most grateful.
When replacing the lock mechanism a chunk of plastic fell out. I suspect that this piece of plastic was jamming the lock. Since I had a new part, I replaced it, but I suspect the new part was not necessary.
it's my turn now! :-D:-D:-D fuses check out the latch arm appears to articulate slightly, but the rear deck lid stays absolutely locked tight, no apparent play, just the warning on the dash. Jeff, I am hoping to avoid your fix for that, but I am certainly unhappy to be gifted with this. I guess I get to go spelunking in the back of my Cayenne this weekend.
Okay, I am not having this problem - Porsche 04 S - my questions is - what warning light came on? Is it just yellow exclamation point? I cannot open or close by rear hatch manually, with key, with rocker switch inside driver's door, etc. The strange this is the warning message - normally it will say "right door open", "left door" etc etc - but for this one it just lets off a horribly long miserable beep, the yellow exclamation point and a picture of car with the whole back end illuminated... arrggghhh, what a nuisance - battery was just replaced in March 2021 - so I'm thinking a fuse? ole number 31? and not a battery problem. Is there a way to make the noise stop while driving? thanks.
