I have the same dashboard noise on my new Cayenne Diesel as well. I can't figure out if it's coming from the air vents or the speedo area.

Sometimes, it just starts to rattle non-stop when I'm on the highway. If some others are not experiencing this rattle, then ours must have some sort of issue.

Knowing how dealers are.. You need to hound your service manager. Be nice but firm. Because it is really unacceptable to pay $70-90k large and have rattles and creaks.

Hey Guys,
So I was able to take a video of another issue. I hear this intermittent buzzing/static from the passenger side of the dashboard. It almost sounds like static. Please tell me if you guys can hear it as well, and if anyone has experienced this.

Also uploading video of my dashboard rattle. Will share that link shortly.

Thanks
Simer

Okay Here is the Rattle Video. Really bad video, and it's dark but you'll be able to hear the rattle from 00:40 seconds onwards...

Yeah, that rattle would drive me nuts. Yikes!

I have a 6 month old V6 (not diesel), and when I brought my Cayenne in for the "legendary" clock repairs, I gave them a laundry list of very minor rattles (not as bad as yours). These also come and go from day to day, and happen at certain temperatures.

- Driver side vent rattle exactly as your video 1.
- Whole dash rattles with resonance at 3800RPM (not quite like your video #2, but perhaps similar cause).
- Squeak from back seat.
- ticking sound from back seat.

Additionally I had engine vibration accelerating at 3800RPM, and de-accelerating or coasting at 1100RPM.

Dealer said they fixed rattles (definitely an improvement but some rattles are still there). Additionally, some of the rattles and engine vibrations are apparently caused by "defective down pipes", and I now have a new set on back order from Germany !?! Never heard of a "down pipe" issue with new Cayennes, but low and behold lots of mentions on VW forums where the natural vibrations of the VR6 has to be quashed with carefully tuned and weighted downpipes! Obviously wont be the same on the Diesel ....

Will chime in when I get the new down-pipes, and see if they tame the VW V6 into a new-found smoothness! Mine was kinda rough from day one (expected that from test-drives, feedback on the forums, and the price for a $14K savings), but seems to have gotten a bit worst with either winter temperatures or time (or both).

I will probably just have to keep mentioning some rattles at every service, in an ongoing attempt to have an absolutely rattle/tick/vibration free car From countless posts here, this is not the Cayennes strong point.

@Steve - The buzzing/rattle sound on your driver side compared to my video 1, is it constant for you? That noise for me is intermittent. and can come out of nowhere even at very low speeds on smooth roads.

The sound coming from your vent is caused by the ball bearing failing inside the fan motor. I had that once on a Benz. Dealer swapped out the entire motor unit for a new one. It should be a quick fix if dealer has the part.

Mine happens some days, not on others, and at any speed and RPM. Kinda like your video, but perhaps more ticking sounds than constant rattle, then stops. If I push in all the snapped together plastic parts, that "seems" to affect it. I would think it is more the plastic clips ticking (just push on the pieces and listen to it creak) ... than what Laiceps describes. I.e. seems more a surface sound, than from the fan motor bearings from within. I think I hardly hear it anymore since dealer did something (or a coincidence and it will come back).

A similar but different sound can be if you have a bunch of things on your keys chain dangling there, but should not be the case for you on the passenger side!

simer,

Thanks for taking the time to make those videos. I have the exact same rattle/ticking noise that you experience coming from the air vent area! Except mine is coming from both the drivers and passengers side. Drives me insane...hopefully we can get to the bottom of this.

@Cali,
It's good to know that this is not normal. I have taken this car two the dealer twice, and each time they say "It's pretty normal for a Porsche". This will be my third attempt.
By the way, My car is less than a month old and have had these issues from day one.

I too have the intermittent buzzing noise from the driver's side. The dealer could not replicate it but found noise from the passenger side. Apparently there is a Porsche CD that allows the dealership to detect rattles/noises.

Thanks for the review, enjoy your diesel!

324 miles on our CD and no such rattles or noises. In fact, it's been super quiet all around. Will report back if rattles/noises start appearing. Our town has concrete roads which are really bouncy so if there were any rattles we'd know right away.

1300 miles on my CD, no rattles so far, great driving vehicule.

27.1 and 27.8 mpg so far, mixed freeway and around the subdivision driving.
