Correct alternator?

I sure hope you are right, but the quality aftermarket parts producers have not proven to be so kind to Cayenne owners when you look at the gouging still going on with things like engine rebuilds, headlights, air struts, the 8 different $100+ plastic vacuum lines, wheel bearings, etc. I guess there are some cheaper aftermarket options available like waterpumps that will ruin your engine block or control arms with bushings that will fail in a few years time.

I've purchased all 8 of the $100 plastic vacuum lines over the last few years if that makes you feel better.
Edit: most of them are actually in the $115-$130 range...

Track Day
Good to review this before you dive in
thanks so everyone here for their help! I did it.
If I were going to do this alternator job again, I would have saved a couple trips to the store if I had these in advance:
1. Three new gallons of coolant and a funnel. Distilled water, if you don't buy the 50/50 mix.
2. Four m10-125 150mm (or longer) bolts. These are metric screws. Doesn't matter if they are/aren't hex heads. (just order these, they were impossible to get in my U.S. town of 3 million.)
3. Torx 6 Star Female Bit Socket Set Can't remove alternator without these. You also need a long, medium and short length Rachel set extension.
4. A bad *** glue kit specifically for plastic that has an agent that activates a permanent bond. The plastic parts the manual told me to buy did not fit the alternator that arrived, so I had to re-use some of the existing plastic pieces. The base of one of them broke a little and I was glad I could save it. That would have left me without a vehicle for a couple weeks.
5. A with various plastic screws for securing undercarriage, wheel well, plastic covers in the engine. As I got "intimate" with my vehicle I found many that had fallen off and I was glad I could replace them.
6. It would be nice to have a friend help you when you put the wheel well plastic back in. That was hard to do alone.
Work hours?
I am new to vehicle repair, and was working alone. It took me 2 solid long days (counting store trips) to do this job. This video said that 2 pro guys who work on cars all the time could do it in ~3.5 hours.
Tips:
Here is a video I made that explains what "Detach lock mount - Service position" is. It is important.
You gotta take picture of the screws in EVERY section before you start removing screws. This job requires you to remove roughly 60 screws of various sizes and locations.
I wish I had followed the instructions to clamp the coolant line before I disconnected it from the alternator. I had already drained the line, so I was lazy and figured it would be fine. It was not fine.
Stalling?
When I first started the car back up, it stalled immediately. Then I would try again and it would stay on. It did this about 6 times, but has not since I drove it on the highway for about 20 minutes.
Over that same time, some other error lights went away.
Soundtrack?
I found this job paired well with there album Kind of Blue by Miles Davis. I tried heavy metal, but don't recommend it.
