how hot does ur 640d runs

[gravityegg]

I just recently bought a 640d with n57, which worries me a bit is the coolant temp runs a bit high, mine runs at 98c for coolant and 100c for oil temp.
i also own a 320d which runs 89c for coolant temp and 100c for thw oil.

not sure others, but 98c for coolant seems too hot for me.
i have a8 4.2tdi which coolant temp stays on 90 and never over.

i have been doing some research and thinking might be the active raditor grille was trying to keep the temp up for better eco.

did anypne here delete the active raditor grille? and what coolant temp did ur 640d runs.

thanks from nz
