About 5/2020 SiriusXM free weekend download affected many PCM units requiring reset. Mine included. The reset fixed the continuous rebooting but left my location corrupted- locates me about 150 miles away and the compass is off 180 degrees.
SiriusXM seemed to admit to causing the problem as they had me take the car back to the dealer so that they could communicate directly with the technician. There may have been a fix. Told to wait and see if held for 48 hours. Reverted back to corrupted state by the time I drove off a few hours later.
Worst case? They tried to surreptitiously tie into my location for ad tracking. Fix would be to initialize the system. Then do updates.
Any ideas? Told to buy a new PCM for $4000 USD. Prefer not to do that.

I have a 2009 957 3.6l v6 Cayenne. The battery was dead a few days ago so I replaced it. It now starts up just as it should but when run a diagnostic it says the alternator voltage is high reading 14.72. I’m assuming I need to replace the alternator to remedy this. I can’t find any information about replacing the alternator. Has anyone attempted this? It looks like it might be straightforward but my concern is whether or not the intake manifold has to be removed in order to get clear access. If anyone has any insight on this I would greatly appreciate it.
Does anyone have a wiring diagram for the seat on a 2008/957 Cayenne which they can let me have?
I’m trying to chase a fault where the passenger seat will motor up and down and the backrest will adjust forward and aft, but there is no response from the controls to move the seat unit forwards and backwards, or the four-way lumber support control.
Thanks in anticipation...
The navigation dvd drive in my 2006 997.1 C4S has failed. It will not eject the dvd. I want to remove the drive unit in order to attempt a repair or, if necessary, replace it. My problem is that I have been unable to remove the plastic piece that covers the dvd drive and audio amp. Porsche said "it just drops down." I have pushed, pulled, and cursed at the cover but it will not budge. I hesitate to use a tool as a lever for fear of breaking the cover.
Do I need to eat more Wheaties so I can pull harder on the cover, or am I just missing a simple solution?
My front wheel was making a rattling noise for about the last week, and this morning as I drove out of my driveway and turned the wheel, I could hear a loud popping noise coming from my wheel whenever I turned. My best guess is that I drove over a pothole and the control arm / bushing moved out of place. Would this be covered under the OE warranty? Or should I take it to a mechanic?
