2025 GLC43 AMG Weird Idle, High oil temp

Just took delivery of a 2025 GLC43 AMG, 100 miles on the dash and in park at idle I get odd stutters, almost feels like the motor is hitching or misfiring. No fluctuation in RPM's either. Also, I noted today in very normal driving and at idle in comfort mode my engine oil temp was far higher than the other temps. (214 degrees at idle) Any ideas? Other temps, Gearbox (183) Coolant (192). All Fahrenheit.

That is strange, and I guess no CEL? Time to head back to the dealership : (

That said, I thought 214 degrees is actually normal.. ish for engine oil for this vehicle though?

Okay flashing CEL needs to go back to the dealership, don't recommend driving with a flashing CEL, get it towed by MB roadside to the dealership, you can technically drive with a solid CEL but not recommend with a flashing one. Sorry to hear about this by the way : (

Flashing CEL went away after 5 seconds, has not come back solid or flashing but definetly weird behavior if car idles for more than 5-10mins and has a hiccup on startups. Smelling burnt plastic in the garage I suspect they did not conduct the PDI properly, washer fluid reservoir also empty??

Looks like they rushed things this time.
