BOSE Speaker Vibration Parcel Shelf
 

Hi,

Had my second hand A8 3.0 SE Exec for about 3 months now. Fantastic car!

Recently it has developed vibrations on the parcel shelf at the back. Depending on the music play this is non-existent to really irritating (have to change the song!). When I was looking for A8s I noticed 3 cars that had this vibration, this one did not but it has developed (or may the music choice just got bassey). I'm 100% sure the speakers are fine, just the parcel shelf can not take the bass.

Anyone else faced this issue and have they got Audi to fix it?

Mine seems fine with Bass, even at significant volumes across all types, and my previous car was fine, so couldn't comment. Do those cars all have rear blinds?

I had something similar on my old D2, I always thought that was the blind mechanism rattling.

I've got standard speakers and it definitely does it ... I just turned down the base and subwoofer till it stopped.

Would be interested to see how you get on with the dealer. Is your car still in warranty?

Yeah still under warranty.
I talked to them and they said something about putting in something to dampen the vibrations. Sometimes I prefer no shelf if it help!
Will probably go see them in the new year.

Cheers for that. I will do the same.

Hi chaps old thread but I have noticed the same on mine, Bose system vibration on the rear shelf didn't have this in the d3 you could wind that up full and nothing rattled!

I sat in the back today and placed my hand on the shelf when it occurs and it stopped so I guess it's the shelf not the speakers. Certain frequencies seem to set it off on certain tunes. Did anyone get this fixed before I tackle the local Audi boys? I looked underneath but it's all covered so needs striping to get assess.
Also noticed there's a movement in the drivers seat ....like the seat is slightly loose on its fixings. I have read on another form this is a fairly simple if involving a fibre washer .... Again anyone noticed this ?
Other than that the car is faultless and a really nice bit of kit, mpg is astonishing for such a large motor and so quiet and comfortable. I have had to to set the speed alert :ROFL:
Cheers Glyn

Too lazy to take it in for the speaker shelf. Seems to have stopped vibrating.

Not had the driver's seat issue, but I'm on 35K now, so maybe something for later.

Try this Audio CD rip..

GET THIS TORRENT
and see what frequency it does it at on the bass sweeps, then you can put on track repeat and try prodding and poking until it stops.
You need to download an app called UTorrent before you click the links above.

Revival of an old thread. My D4 developed a buzzing (farty) noise from the rear central subwoofer. Removal of the grille revealed the speaker central dome was coming adrift and vibrating at certain frequencies. I bought a used speaker unit from Prestige (great service as usual) and today attempted to change them out. We took the upper boot trim out with a view to bring it out that way but there was no way that could be done. To take it out would entail removing the parcel shelf which appears to be a massive job. We decided to try dribbling flexible super-glue around the rim of the dome.It appears to have worked. We'll see if it lasts. I have the replacement if push comes to shove. Fingers crossed. Hoping this may help someone in the future.
