Please reduce engine load message
Believe it or not, the only thing that gets me stressed out about this is not being able to enjoy my car while it is at the dealer.

Believe it or not, the only thing that gets me stressed out about this is not being able to enjoy my car while it is at the dealer. I will continue to use it as it was intended to be used regardless. If it happens again, I will have it towed to the dealer, over and over until it is either fixed or the AZ lemon law kicks in.

I don't get it either. If the existing two radiators and controls are working correctly, then the water temp should have shot up if the oil went up that much. Having a third unit gives extra capacity, of course, but as long at the water temp is 194 F (90 C) then there should have been capacity to keep the oil from going this high.
I think Porsche has just programmed a 194F into the water temp.
Mine used to read 205 continuously, then after an update now reads 194 continuously.
I hope so...11 days so far at the dealer and have not heard anything except for data has been uploaded to PCNA and then crickets.

I was tracking 2 weeks ago when, 15 minutes into the second 20 minute session, my power dropped, the message "Please reduce engine load" message appeared and the oil temp jumped to close to 280-290. Coolant temp remained in control throughout. I immediately pulled off and drove off switching back to normal mode from sports plus. Message cleared itself. Brought the car to dealer 9 days ago. The dealer tells me they uploaded the info to Porsche Car NA and still waiting for guidance.
Anyone else experienced this?

A DE event would not matter. Club Racing, a timed event, probably would. Our major dealerships sponsor PCA DE events here. In fact, my dealership Sales Manager just took my buddy and me to a private track event 2 weeks ago. It probably helped that I referred my buddy to him to purchase his new 991 Turbo.
Sure seems odd that the dealer and PCNA haven't made any progress as yet. Here's a link to Porsche's service information document (relevant section starts @ pg. 64).

Seems like the coolant/oil heat exchanger could be a likely culprit, but you would think they would have been able to identify it fairly easily. Hope you're back on the road soon.

UPDATE:
After 2 weeks I finally got the car back. The fault was caused by overheating transmission. They replaced the trans temp sensor under warranty.
Last week I used the car under spirited driving conditions, Sports Plus in auto and after 10-15 minutes of driving the oil temp increased to 265F. No engine fault but still hot. I let my dealer know and the foreman's answer was: "The avg rpm is more than likely consistently over 4 or 5k in sport plus mode auto. The car should run much cooler if you leave it in sport mode not sport plus and auto and the lap times will probably be the same." ...which I interpret as " do not use sports mode plus for spirited driving".
I am escalating. Question:
When you guys use sports plus in auto, what is your oil temp?

My car is a 7MT and PowerKit, so different than you, but in Sport Plus, and spirited driving, the highest oil temp I've seen is 232 in +95 degree humid weather.
While the dealers may participate in DE events, and will go to bat for you to get damage repaired, PCNA takes a different outlook on paying for your track related repairs.
I'd keep that info to yourself that the situation happened while on track.
