Not sure if it is the same problem but my parking brake light would come on intermittently whenever I go over bumpy stuff like railroad crossing so on my last visit to the dealer, I told the service advisor and right away he said the complete assembly needs to be replaced. No problem since.

Let me know how it goes, as I've not repaired mine yet. Good luck!

Hi; I own an 04' Cayenne and i am having trouble with the rear tailgate. The ones from the rear glass are ok,since I never open de glass,but need to know how to replace the lift supports from de tailgate.

 

It was such an issue in my 06 I carried a golf club back there......then one day forgot I propped up the back with it and went to close the lid with some force...........one less golf club..

 

Parts Needed:
955.512.550.03 Rear Lid Dampers (2 required)

Removal

Notes:
- To remove the pneumatic springs, they must be in idle state: rear lid open.
- The rear lid must be secured against accidental closure after removing the pneumatic springs.
- Pneumatic springs must not be opened using force extreme internal pressure.

Note: Some of the interior lining pieces can be fragile so handle them with care.

1. Open rear window and rear lid.
2. Remove rear roof lining:
- Unclip interior light on the roof lining.
- Pull off plug.
- Unclip roof lining at marked positions. To do so, lift the lining slightly at the rear and lever the clip connection out using a screwdriver.
3. Remove the D−pillar trim:
Note: When unclipping the D−pillar trim using a tool, make sure not to damage the electrical wires lying behind it and the head airbag.
- Open cover for luggage compartment net partition.
- Unscrew fastening screw.
- Unclip D−pillar trim (5 locations in the middle) from the interior D−pillar. To do so, raise trim slightly and lever out the fastening clips using a screwdriver.
- Unclip D−pillar trim where it joins rear side trim.
- Unclip D−pillar trim from interior D−pillar at the bottom. To do so, raise trim slightly and lever out the fastening clips using a screwdriver.
- Only in vehicles with BOSE sound system: Pull off plug from the loudspeaker.
- Remove D−pillar trim.
4. Remove rear grab handles at left and right:
- Unfold grab handle, Unclip cover, Unscrew fastening screws.
- Remove grab handle.
5. Unscrew the fastening screws .


6. Unclip and remove the deformation element.


7. Cut open the bonded joint on the cover with a knife and remove the cover.
8. Remove any sealant residue on the cover and on the body.
9. Secure rear lid so that it cannot fall shut accidentally. It is very heavy and one strut will not hold it up.
10. Loosen the retaining clips on the pneumatic spring for the rear lid at the ball sockets using a screwdriver and remove the clips.


11. Pull the pneumatic spring for the rear lid from the ball heads and remove.



Installation

1. Place the retaining clips on the pneumatic spring for the rear lid at the ball sockets and press into position.
2. Press the pneumatic spring for the rear lid on to the ball heads until the retaining clips engage perceptibly.
3. Apply Klebt und Dichtet sealant to the cover and stick on the cover.
Note: After sticking on the cover, allow the sealant to dry for about 60 minutes.
4. Position and clip in the deformation element .
5. Insert the fastening screws and tighten to the 2 ftlbs (3 Nm).
6. Install rear grab handles at left and right (reverse of above).
7. Install D−pillar trim (reverse of above).
8. Install rear roof lining (reverse of above).
9. Remove the rear lid bracing device and carefully test the lid.

 

It is a good idea to replace both the lid and the glass struts at the same time while you are in there. They are both used to hold the heavy gate up, I bet you can guess why I know that.

 

Mine would do it - every winter it would just fall back down - after the second set of gas struts just gave up...

Must be with the 2nd generation went with the motors - my T-Rex hasn't had such an issue and it has been in some pretty cold weather as of late....
