Strong jerk when accelerating
I have a problem with Mercedes w205 c200 year 2016 petrol 4x4.
In my case, jerking occurs very rarely, but usually when I press the gas pedal hard. Strong jerk sometimes two. Audible hit. The effect on the automatic and manual gear shift mode. I checked whether the effect occurs when dropping the gear.
A moment later I can trample as much as I want and everything is fine. The engine turns on beautifully and gives off power.
The car at idle and calm driving works properly. Evenly and quietly. No errors on OBD2.
With hard driving, no problems for weeks. The car accelerates properly. Nothing happens until it's just...YEP! A strong jerk and a sudden drop in power for 1/2 second and a moment later it's OK.
I replaced a damaged pear from the turbine. What's next?
I changed the oil in the gearbox. There is jerking when pressing hard. The revs drop when you jerk. If I do not let go of the gas, it happens that the gearbox switches to D mode and cannot be changed to Manual. I've been in higher gears ever since. No power. WTF!The dealerships don't know what's causing it. The car was connected to the computer. ZERO errors.

Hi there, are you facing the same problem? I faced a similar issue in the fall and fixed it by getting my crankshaft position sensor (primary issue) and pedal value sensor replaced. HAven't had any issues since.

hard faults... don't go quietly
These faults are classified with top severity by ECU:
-- CKP stops the engine dead
-- APP limp-modes at the very first occurrence.
Normal driving is interrupted with this class of hard faults.
Zero chance of both defective parts at the same time.
