Hello everyone, I'm the proud owner of a 2016 S350D V222 with 98k miles. Under warranty.
I've already driven 4k miles with it and it has been a huge pleasure (coming from a near-base w204 2013)

However, I have a small issue regarding ESP.

Here's my problem :
Whenever I full-throttle, ESP activates and stops the acceleration. This causes the acceleration to stop completely and thus, a very uncomfortable ride lol.
This is 100% not normal, I have a 220 and had a 204 and they never behaved like that. I know how ESP works and this should not happen.
This issue does not happen every time, thankfully or I would've lost my mind, it happens sometimes when the road is not perfectly straight or in good condition. It also sometimes happens when all the conditions are met (but very rarely).

The 4 tires have been changed to Michelin Pilot Sport (275/40/19 for the rear and 245/45/19 for the front) and I still have this problem.
Mercedes checked and they have no error codes whatsoever.

I have read on some forums that this could be caused by a soon-to-be bad sensor that would report false values to the ESP.

Could anyone help me there ? I'd really love to have a better racing experience with it lol

Other infos :
The ESP light is on when the car is stopping the acceleration but then disappears (so that's normal)
I haven't purged the brake fluid since probably a long time. (what would be the reasonable due?)
I've never tried to disable the ESP, i'm too scared of that

Sounds normal to me...back off the throttle if it bothers you or disable it and let the tail hang out :-)

This is the car's attempt to keep you from needing another car, mostly driven by the laws of physics.
A heavy car with a high torque engine will spin the wheels easily, consider applying the throttle proportional to surface grip.
​​​​​​Not sure if that car has ESP sport mode, this would reduce intervention, reducing the margin of safety.

Looks like OP created two threads for the same thing, so just posting what I said in the other thread. And just for comparison, my AMG also makes 700NM, all going to the rear wheels only. It also makes over 200hp more, but too much torque vs. too little frictional grip is what causes loss of traction. I spin my tires constantly even on dry roads with 285s in the rear. It's fun to hang out the tail! But to the point below, my car has an electronic locking rear differential, so instead of traction control cutting engine power and scrambling to control the wheel spin, the rear differential actively distributes the torque between the wheels based on available grip to maximize the available traction. I also have a 9-stage traction control system, so I can dial in exactly how much wheel spin I want. As said above, if this car has ESP Sport mode, then you can reduce the intervention a bit as long as you are prepared to handle a slide, but at the end of the day it's not a sports car and it doesn't have a locking rear differential.

These cars are really hard to peel out with.
my suburban with the 6.2 though? That thing smokes em.

The fundamental problem with peeling out with an open differential and no traction control is that you end up burning out one tire and barely going anywhere as demonstrated by this hooligan in a pickup truck. One of the wheels will just spin and not meet much resistance, so barely any driving torque is going to the other wheel. Traction control is needed here to apply the brake on the spinning wheel and give it resistance so that enough torque is sent to the other wheel and get the car moving. This function of the traction control system is commonly referred to as EDL (Electronic Differential Lock). EDL uses the brakes to simulate a locking differential. The differential itself doesn't actually lock. This system can be rather jarring as it's trying to figure out the correct amount of braking torque to get the car moving and on very slippery surfaces like snow it tends to get the car completely stuck as it essentially stalls the wheels.

Hello thanks a lot for your answer. Sorry for the double post, I forgot I had another one (but it had not gotten any answer till yesterday)
So the main issue here is traction control, I did some research and I did not know it was slightly different from ESP.
Indeed, it's not a sports car and therefore doesn't have a sport ESP mode, unfortunately.
