3.6l Cayenne alternator replacement

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.

That charging number is pretty close to normal.

Are you sure you do not have a short or device causing a power draw. This can be measured with an amp meter easily and should be under 100 ma.

Thanks so much for your response! I thought that it was pretty close to where it should be but wanted to play on the safe side. The only thing I have added is a pedal commander which increases pedal sensitivity. I don’t know if that could be causing any power draw and forgive my ignorance I’m not very savvy with electrical systems.
