I have an '09 Cayenne GTS. The pano roof squeaks when driving on certain road conditions, typically lower speeds. I've had it to the Porsche service centre for lubrication which fixes the problem for about a year. Hoping to learn how to lubricate this myself. I cannot find anything on YouTube. Any suggestions?

 

I lubricate the tracks and anything that slides with Blaster Dry Teflon spray. Goes on as a liquid out of the can, the carrier solvent evaporates away leaving a coating of Teflon behind. Works great because it doesn't attract dirt.like grease and oils do.

For the seals, I treat them with Gummi Pflege. Do this each year and it will keep the roof operating as it should.

Thanks for the this. Appreciate the advice.

 

It is actually the glass? Push on the front corners of the glass, you may need to do the little shim mod under the rail.

 

is there a shim mod for the 955 roof? I want to raise my front panel where it meets glass diverter.

 

Mr P
Which Gummi?
They seem to vary widely ethylene glycol / siloxane / mineral oil

So I happened to be driving by my local Porsche dealer and decided to stop in an see if the service manager had any advice for a DIY. To lubricate the seals, he recommended I stop by a GM dealer and purchase AC Delco Silicone Emulsion for about $5 per bottle. Said it's better that what Porsche can offer. I tried it and it's helping. May need a second application (of course i cleaned all this first).

For the mechanism, he recommended from VW, Solid Lubricant Paste part # G 060 751 A2. He says the tube installs in a caulking gun but to use a small stir stick or similar to apply it directly onto the moving mechanism parts. Pricy at about $60. May try the teflon spray suggested by Petza914 in this post. Sounds like it may be easier to apply.

 

Any paste or grease type lubricant attracts dirt and that dirt is counter productive to the desired goal. That's the great thing about the dry Teflon spray.
