CLS63 engine heat?
its well known that if you get this and you let it happen alot, that your suspension is going to go BOOM due to the intense heat!
!.....well i had to had my spot of fun. MY guess is its normal and these cars have big engines with big power and the heat you are feeling is just it venting through.
I usually get it to after spirited driving its normal....try popping the hood then u will feel the heat escape

Enjoy and in good health

Btw, does you oil temperature usually stay around 100-112 degrees celcius?

Btw, does you oil temperature usually stay around 100-112 degrees celcius?The Best of Mercedes & AMG
im in sunny LA, and my temperature never goes above 102 except on a really sunny day... if the temp outside is 100 (a month ago), it goes up to 105-107

My guess is unless we get the temp warning light, our car should be able to handle the heat.
Today, L.A. was in the high 90's F and some 100's F in other places; my oil temp got to 129 C when crawling on the freeway.

Checked the dipstick when I got home and it was around the 3/4 filled mark so there definitely was enough oil.
First, there is approximate 3% (6 degrees in 200) permitted by law for tolerences in gagues.
When the Dealer changed out my instrument cluster, I noticed that my normal running temp of a hair below 100 all of a sudden changed to a hair above 100 with the new instrument cluster. Same car, same condiitons.
I think what we must notice is a change in the normal range of temp, not the actual reading. So if your beast is always at 103, become concerned when under the same conditions it changes to 110.

I was on local street, stop and go, stop and go.
Any advice?
You use manul mode during stop and go traffic?

Oh, yeah that temperature is normal.
I drive almost exclusively in Manual mode. Approximately 95% of the time the car is driven in Manual. I would say that I typically hold a gear at 3,600 -3,900 RPM under normal city driving. Highway cruising I drop down to 3,000 - 3,200 RPM.
Just today, the gauge was reading at 123 Celsius and thats on the highway.
"The ideal operating range for engine oil is 180°F through 200°F. While operating within this range, the oil works as a lubricant, coolant, and cleansing agent in the engine. Modern engines generally run with radiator coolant temperatures between 200°F and 220°F with oil temperature ranges between 20°F and 75°F HOTTER. In other words, when the engine is performing flawlessly, the engine oil is already overheating! Oil that exceeds 220°F rapidly loses its ability to lubricate and cool causing accerlerated fatigue and premature component failure."

I'm wondering if adding an aftermarket oil cooler can bring the temperature down.
