RPM is getting unstable at first run
I'm driving a W204 C220 from 2007 and I'm facing the following issues:
- In each morning when the outside temperature is lower than 10 degrees Celsius my car is going crazy. For about 2 kilometers ( maybe after something is getting heated up ) when I'm accelerating but very gentile the engine revs up and down on it's own even the gas pedal is almost steady as position. For better explanation please watch the video (best at 1:47 ) :
. I have started to have this issue since the winter came ( around 1 month ). After those 2 kilometers all is running smooth even during the rest of the day. The trans fluid was changed 30.000 kilometers ago ( at 150k )
- Monday I had to go out of town and I've noticed that the coolant I added ~ 2 months ago it's gone ( the coolant warning appeared for a short time , after checking the coolant container I saw that the level is not the same as then ) also I noticed that the thermostat needs to be changed cause the temperature is not getting higher than 60 degrees .
Thanks in advance for all the help provided!
