Jerky throttle response when the engine is cold
This is only happening when the engine is cold. When I start from a traffic light stop, I release the brake, give just a little gas, and then it feels the throttle would open too much and quickly close down to what it should be. Once I drive it for ~3 miles and the engine is warmed up, the acceleration becomes linear again. Does anyone know if this is normal or what component I should check or clean?

Are you in C, S, S+, details help
My instinct and knowledge about this platform tells me that this is pretty typical and things that people would complain about even when they bought the car brand new, this car is new to you then you need to get used to driving this type of MCT transmission as it's very different than a torque converter-based transmission. This is one of the nuances. That being said if you provide more details we may be able to help you figure out if something needs to be modified such as a re-adaptation of your wet clutch in the MCT or a re adaptation of the transmission in general

When it is cold outside, the trans will start off on 2nd gear (regardless of C/S/S+ selected setting) until it reached a certain temp, usually the warm up does not take very long. But during this time, cold fluid / pulling away in 2nd I do find the clutch engagements to cause the car to jerk a little when pulling away from a standstill, only.

You'll have to pull the choke all the way out, at least for a couple of miles. This should help.
BTW, that's pretty normal behavior. Gearbox starts in 2nd, gear oil is super cold and the clutch mechanism has a hard time trying to engage smoothly. Typically stops within the first take off. At least on our side of the shore.

this is just never going to be a car you can just turn on when it's a cold engine and expect it to drive normal ... your foot gets used to it tho

I'm experiencing this same thing now with my E63, and I got this same behavior with my CLA45 and that had a DCT. Particularly in cold weather.

Sorry I forgot to update this thread. I took the car to the dealer and the SA seemed to immediately know what I was talking about and said it’s normal for these bi-turbo V8s. It probably takes longer time to circulate all kinds of fluids when cold. If it missed a gear, it would pop a code immediately.

Just feather the throttle a bit when cold and it'll warm up nicely as you pull away - your foot will develop a "foot memory" to make this seamless in the future like driving a manual transmission/clutch

2014 AMG E63s wagon
Thankful for this thread, I'm having the same issue. Learning this (new to me) wagon and surprised that this is just a quirk, but can get used to it. I had one this morning that was bad enough I thought the person behind me might rear end me. It does go away once warmed up. 2014 e63s wagon w/ 73k miles. I've monitored the transmission temp screen when driving and it takes A LONG time for that temp to get up, probably 30min of driving at least. Brand new fluid.

good catch
maybe he's referring to the engine oil/coolant temp and correlating it with trans temp ??
unless he's logging the car and - is there a trans temp we can access with icarsoft or another scanner?

haha, sorry - before everybody runs out to try to find that screen, meant the coolant and oil temp monitors, using coolant temp as a general correlation to transmission temp (maybe there isn't one? is that not a good go-by?). Regarding the jerkiness though, it seems like it can happen anytime when accelerating from a stop within the first 10minutes of driving.

Good clarification, Jerky normal when cold. Trans temp gonna be different than oil temp. You need icarsoft or something similar for trans temp. You may want to peruse thr oil solenoid thread. That reduces oil warm up.
