Hello guys! How are you doing?
I have a C220 W204 2009 and have a problem with fluctuating rpm between 20-80 rpm. This only happens when the gas pedal is slightly pressed and in high gear. When the car is idling or the rpm's are above 2k there isn't a problem, 0 fluctuations.
If there's a hill and you press the gas pedal a lot while the car is with low rpm the rpm fluctuation is very visible.
I have checked & cleaned EGR, changed every filter, changed the engine and transmission oil, checked the injectors, cleaned the DPF, checked for vacuum leaks, checked the turbo, changed the fuel pump, done multiple OBD readings, and also checked every sensor in the car and recalibrated them and also did a reset of the transmission.
After all the things that I checked and did, everything seems to be fine.
Now is this a problem or it's a normal thing for an automatic W204?
