M272, what is your idle speed when drive gear?
I had two volvos before, and they idle near 700-750.
My E350 idles 700-800 until engine perfectly warm up.
After some driving, my engine idles at 550rpm, stable. All okay but steering wheel is but heavier than 800.
When I put my gear to N, it moves to near 600rpm.
Is it normal range?
My car is 08 E350 4matic with 5G.
