Deafening buzz from left front dash speaker
A couple times now (3 times in 7 months) on my wifes 2010 GTS, a deafening buzz will come from the left front dash speaker. Turning off the PCM or adjusting volumes does not change its sound - volume or otherwise. Sometimes it will come on for a few minutes, other times (like today) for a hour straight. And then to add insult to injury, we suddenly lost the subscription to XM and the XM radio ID went blank. A few restarts later and all is well.
Sounds like the head unit going out.
Anyone else had anything similar?
Thanks.

We had the buzzing noise as well, it migrated from the left rear to the left front. It would happen after hitting a bump in the road and we would then need to look for some more bumps to turn it off.
The deal replaced the rear speaker, then told us we had some loose change laying around. They were never able to replicate it. We brought it in a third time and that same morning, they had another Cayenne in with the same problem.
They finally found a tech bulletin on the issue and replaced a switch in the system. By the time we picked it up the next day, had a third one in with the same problem.

Electronic buzz sound from left side of dash - 2013 Cayenne Diesel
Does anyone know the name or number of the Tech Service bulletin for this?
We recently started getting an electronic buzz sound from left side of dash. There are no messages or warnings on the dash other than an oil change due in 400 miles. Could this be an aural heads up of an up coming service? Did not see anything in the book to indicate what the buzz sound is for.
Probably unrelated but the key fob / car memory is not working. I can not even get the red set light to come on.
