Could be something with your ignition system, a misfire caused by bad plugs.

I am thinking is the Gas paddle issue. Because it’s only happen when press the gas to go.

I have a 2013 CLS63 AMG that has the same jerky issue. The issue only seems to happen when the Temp outside is below 50 degrees. After the car warms to above 60 degrees I dont seem to have the issue anymore. Not sure if you figured out a solution but would like to hear if you did. I only have 27,000 miles on the car.

I try to ask many people who have experience in that car they told me the problem from Wet clutch solenoid located in transmission

But i can’t say it because i didn’t replace that solenoid before in my car
