I took my Cayenne to the dealer over the winter for service, and when I was working under the car recently, found they cut off part of the undertray that hooks into the transmission crossmember and just zip-tied it on. A couple fasteners and brackets are missing, but I can't find some of the part numbers - was hoping to get some help identifying them so I can replace the zip-tie job.

My car is an 09 GTS 6MT. I'm looking at the rear undertray, which should be part 95550423102.

The undercover has a tongue that fits into a slot on the transmission undercover, but I remember that in addition to the tongue, it's either clamped in place, or hooks onto a bracket. I don't remember that mine ever had brackets, but I've seen pictures of metal tabs like the ones below in several DIY guides. Not sure if this only applies to 955s?

Instead of these brackets, I vaguely remember something like part 95550419900 (part 24 in the diagram below). Did the 957 use this part to clamp the undercover to the transmission crossmember instead of the metal brackets? Maybe mine was just missing them to begin with...

Let me know if anyone recognizes which of these parts are the correct ones to hold the undercover to the transmission support.

 

part 24

 

I unpacked the part marked 24 literally today from Pelican order

Kinda strange though - I have a 2008 CTT and it is just like part 24 in the exploded diagram but the picture of that car suggests a different type of bracket that is kind of spring loaded to keep constant pressure on the tab so it can unhook and come off

Anyways this is what I bought - part #7L0-825-199-VAG, like I said it came from Pelican (my first experience with them and I was very impressed) and cost around $28 - I vaguely remember pricing it at my local dealer (can't remember if I contacted VW or Porsche) and it would have been ~$100

 

Thanks - any idea if it changed from the 955 to 957? Still confused about the metal brackets in the pictures from Pelican's DIY.

Thanks for the feedback. Did it all seem to fit together correctly? I was confused, too, because I've seen pictures of that metal bracket, and my undercover definitely has the slots for the metal fingers, but don't remember those brackets on my car.

 

No metal brackets were on my 08 GTS, just part 24 bolted over the cover panel.

 

Its the same part on my 957 for sure

And just to confirm I do not have those metal fingers - from what I can see you could have one or the other but not both as they both use the same two bolt holes

 

Did anyone resolve this part issue? MY 2009 is missing the silver hooks shown in these photos. Using Zip Ties for now... It is a mystery.

 

Sorry I didn't reply sooner. I ordered the parts, and confirmed part 24 from the parts diagram in my original post was correct. Instead of metal hooks, I guess they now use this plastic piece to clamp the tongue from the undercover against the bracket from the transmission support.

You can see the small plastic part laying on my new undercover in the attached pic (old on top, new below). There's a small difference in duct shape between the two, but it fit up just fine regardless. Note that this undercover was called out as specific to the manual trans models, I don't know if the ducts on the undercover for the auto are any different.

There's no black tall middle duct on the auto trans models.
