2014 C300 4MATIC
Temperature Change

Hello all,


I have the 2014 W204 C300 4Matic and it has about 23,000 miles on it.
A few days ago I was driving on highway and was driving at around 65mph - 70mph and there was sudden change in weather from warm to cool with rain attack.
I believe outside temperature dropped about 10F (from 65F to like 50F's).
When I looked at the odometer and car's temperature, I noticed it has dropped a little from the normal operating temperature.
After a few minutes, car's temperature went back to normal operating temperature it suppose to be.
Could this happened due to change in outside temperature with rain all of sudden?
Or do I have problem with car's thermostat?
Has anyone experienced similar issue?


(Just a side note that the car was in normal operating temperature before I got on highway, and throttle was wide open in S mode while weather was changing)


Thank you all in advance for your comments and help.

Could have changed slightly if you went from a slower speed when you were off the highway to the faster speed when you were on the highway. Rain could have factored a bit as well. As long as it was just a slight variation that sounds normal from your brief description.
