C400 Lauch Problem
I am experiencing an issue with my c400 w205. When my car is in M1 gear and pulling gaz to full throtle from start (0 km/h) it kicks. This kicking is coming from the back and not sure what might be doing this.

Cant say I've had that exact issue but I do notice that when I decide to floor it, the shift is pretty hard from 3rd to 4th gear. Can you describe what the 'kicking' feeling is? Engaging the twin turbos perhaps?

When you want to start accelerating at full throttle you feel that there is 2 metals pulling away from each other from the rear. I don't know how to explain to you exactly, but it is like if two objects are attached together and suddenly they separate apart. (that is the feeling). When driving smoothly nothing is noticeable and my gear shifts are pretty smooth.
Full diagnostic was done for my rear left axle today, and no issues were found. Perhaps the mechanic found that my transmission mount is not as strong as it should, so he mentioned that this might be causing the problem.

Several of the C43/450/400 cars have had to replace failed motor mounts.
When you launce do you have traction control off? You might be feeling the rear brakes quickly grab when the car sees the slight wheel spin.
