Accelerator pedal/gaspedal vibration at low RPM
Recently got my first new C200 CGI. I have been noticing that when the car is driven at around 1500RPM, the accelerator/gas pedal vibrates. Depressing the pedal little more makes it disappear. I sent the car to the dealership for inspection late last week. Their mechanic's initial response - I don't feel any vibration (a response that I was somehow already expecting). Anyway, they kept the car for further inspection, and finally sent it back to me after updating the software, saying that it should hopefully make a difference now. However, unfortunately there is no change.
My questions are - has anyone faced the same problem? If yes,what did they do to get rid of it (the vibration is bothering me quite a lot
)? My previous car was a non-turbo, is it possible that this is how the turbo engines behave at low RPM? Please help.Thanks a lot guys!

I would investigate engine/transmission mounts. Also make sure nothing is touching the firewall in the engine compartment or tunnel. It should be easy to see as it would leave a bright mark.
This is not normal.
Thanks again!
Talked to the dealership service department this evening. They said the mounts would have been checked as well. I don't believe them, so I'm planning to have the car inspected elsewhere. Let's see what they find, and then I'll go back to the dealership for repair. I wish the issue gets diagnosed properly soon.
