What Causes the Jerking Sensation When Releasing the Throttle in a Mercedes-Benz?
2 Answers
There are several reasons for the jerking sensation when releasing the throttle in a Mercedes-Benz: Suspension system failure: The front wheel shock absorbers are in a compressed state, while the rear wheel shock absorbers are in an extended state, creating a front-low, rear-high nodding posture. When the car comes to a complete stop, the front and rear springs return to their original state, causing the front of the car to lift slightly and the rear to lower, resulting in a jerking sensation. Increasing the stiffness of the front suspension can resolve this issue. Sudden braking: When braking abruptly, a jerking sensation may occur. It is advisable to avoid sudden braking and instead slow down gradually when applying the brakes.
I've been driving a Mercedes for over ten years, and experiencing jerking when releasing the throttle is quite a common issue. It mainly depends on whether your car is an automatic or manual transmission. If it's an automatic Mercedes, throttle-off jerking is mostly caused by dirty transmission fluid or incorrect fluid levels. Mercedes automatic transmissions are particularly sensitive; they tend to jerk as soon as the fluid deteriorates. If the fuel injectors have carbon buildup, unstable fuel supply can also cause shaking when releasing the throttle. Issues with sensors, such as the throttle position sensor, can lead to delayed responses from the ECU due to receiving incorrect signals. For manual transmissions, worn clutch plates might cause rough shifting. I recommend first checking the transmission fluid color to see if it's cloudy. If that doesn't help, take it to a professional shop for a diagnostic scan to check for error codes. Although the jerking might seem minor, delaying repairs could lead to more severe damage, such as transmission overheating or a sudden spike in fuel consumption. Don’t skimp on regular maintenance—changing the transmission fluid every two to three years can effectively prevent such issues.
