My 17 Turbo S has higher oil temps in normal mode vs sport or sport plus. Any thoughts.

Driving the PDK in Normal mode the gear selection jump to 6 and 7 gear at a lower RPM. When in Sport mode or Sport plus you have a lower gear> typically...

The water pump is turning faster to supply/circulate coolant.

The engine is producing more power torque in Sport Mode and Sport Plus> coolant system must remove more heat from the cylinder heads and cylinder coolant jackets..

Also the cooling system has to absorb the added/power performance of the PDK coolant loop/heat exchanger.

Mine too. I've seen 115C on a cool day driving steadily at 70mph, put it into Sport Plus and it fell to 103C

In general, higher engine temps lead to better fuel economy (and lower emissions) since more fuel energy is spent expanding the cylinder contents and less heating the head, piston and cylinder walls.
Lower temps in sport modes give you more reserve for absorbing eventual heat rises due to high power operation.
The oil is perfectly happy at the slightly elevated temperature and probably carries less water in stop and go driving.

Don't monitor engine temps then. The car will warn you if there's a problem, so focus on the other side of the windshield.

Many recent cars do that - from BMW 3 series to Cayenne. GT3 does not. It's essentially allowing higher oil temp in a non-sport mode to improve fuel economy, at expense of reduced cooling margin (there is still a lot of margin on the Turbo). Don't worry about it. Use sport model if you are doing repeated launches or driving on the track.
