My issue is related to the Auto Start/Stop function, when outside temp is very low, say below zero Celsius, the front driver speaker cuts off briefly each time the engine restarts, my dealer said it is a known issue on 2013 Canadian Cayenne. Does anyone also experience this? When outside temp is over 10 Celsius, things are normal. Between 0 to 10 Celsius, it may or may not happen. Now that the weather is getting cold, I like to resolve this issue.

 

I think there is no such thing as region specific problem in a porsche. I maybe wrong. But let the dealer fix it before the warranty is up

 

2013 Cayenne GTS. I'm not in Canada, but yesterday afternoon traffic was a nightmare because of all the people on their way over the the river & through the woods to Grandma's for Thanksgiving. So I did engage Auto Stop for all the stop & start traffic.

I noticed that each time I took my foot off the brake and the car started back up, the radio volume dropped noticeably, then almost as quickly came back up to full volume.

Temps in mid-40s F. I'm guessing it's a battery drain due to the power needed to kick the starter.

 

In my case, only the front driver speaker drops volume.

 

There is indeed regional difference. See today's posting 'PCM map question' for another issue unique to Canadian Cayenne.

 

Ok, tested it at -3C on the way home yesterday from work. This is on a V6 with PCM+NAV (so not the base speakers, but not the Bose/Burmeister ones either) testing with music coming from both the internal jukebox harddrive and from the radio (I don't have any CDs anymore). Had no issues with either audio cutting in and out during stop/start or any perceivable decrease in volume..

 

Thanks so much. I hope my dealer can solve the problem.
