Hi! I own a C220 CDI Coupe with a manual gearbox, and noticed that when driving in traffic jams in 1st or 2nd gear at low RPMs (1-2k) and at constant rate with low press on the gas - the car occasionally slightly hesitates. It is only slightly, but it can be also noticed at the RPM indicator as it slightly jumps up and down in the range of say 50 RPMs. If I keep the same amount of gas, it stop after a few seconds, while if I press harder or release the paddle it stops as well. Anyone had a similar thing? Thank you!
