Cayenne rear tailgate soft close

[Aza]

Hi All,

My 2005 type 955 has developed a problem with the rear hatch door. I opened the car to clean it and the central locking worked as it should but when I locked it up again the rear door soft close didn't work.

So far I have:
Checked the central locking fuse although all passenger/ driver doors lock and I have checked the rear door soft close fuse - all are OK;
Removed the lower locking mechanism and cleaned it (not the grease!) The mechanism doesn't seem to be seized;
When I press on the top latch mechanism, the 'first position' turns the boot lights off but nothing else happens.

Should the lower mechanism do something? If so, how is it controlled?

Any help is appreciated.

It may be nothing to do with the problem but the tailgate springs
are notorious for weakening.I have to manually close mine and slam it.
It will not stay open on the springs either
I will get it fixed eventually

I have since sold my Cayenne Turbo however if I recall correctly the latch on the main rear door should activate the lower ‘grab motor’ to pull it in really tight.
So you should be able to test it by closing just the latch on the tailgate a screwdriver, which should turn off the red lights and activate the latch pull motor.

I’m sure I read some strange story about how it was a bit of an afterthought to have that pull mechanism fitted (under the chrome plates on boot floor) due to the Cayenne body seals being so airtight that people would fail to close the tailgate!

i had it fail on my previous Cayenne and replaced the motor pull mechanism in the boot floor with a working unit.
