Hello everyone, I have a V222 350d 2016 (pre-facelift). It has 300HP and 700NM of torque.
It has michelin pilot sport 4's and 5's, the dimensions are 245/45 19 in the front and 275/40 in the back. They have 10 000 km (6000 miles) and are in great shape.

Ever since I got this car in august, I noticed a very strong ESP and clearly abnormal.
Sometimes, when I try a full-throttle, the ESP would activate and litterally prevent me from accelerating for a second accompanied by a very hard "shock".
This problem especially happens when I'm pressing the gas in a corner. It's normal to have ESP but not this harsh.
It's extremely disturbing and frustrating.

I have had a W204 2013 C250 CDI and I have a W220 S320 CDI, the ESP has never done that even when full-throttling.
So i'm asking here, Mercedes doesn't seem to see an issue, there doesn't seem to have any error codes..
Has anyone experienced that ? Do you think it's normal ? What could be the problem ?

 

Sounds like it's losing traction and traction control kicks in. Are the roads wet or dry? Your other cars had about 200NM less torque, so not as likely to break traction. I'm assuming this car is RWD? If so, this is not atypical especially if you step on the throttle in a corner. When turning, the outer tire gets light and can't put down as much torque, and because an open differential always splits torque 50:50 the inner tire can't put more torque down than the outer, so you'll be at the mercy of the outer tire having enough grip. RWD kinda sucks unless you have at least a limited slip differential in the rear, so that the driving torque gets sent to the wheel that has traction. Otherwise the car just scrambles and uses the brakes to slow down the wheel that's losing traction in order to send torque to the wheel that has traction and it'll cut engine torque to manage it all.

 

Please don't create multiple threads for the same thing.

This is expected behavior for a high torque engine on a heavy car.
Also the intervention might feel more abrupt due to the high compression of the diesel.
