Why does my Mercedes C class produce vibrations when accelerating?

So let’s begin our article with the roots of this kind of problem on your car. You should already know that an engine, specifically if it is ancient or if it has been driven quite a lot, can naturally vibrate without being a problem behind it. Large diesel engines, specifically those with a lot of torque, can generate this sort of feeling, both at idle and when accelerating.

I feel vibrations on my Mercedes C class only when accelerating

Let’s take the most interesting case for us in this article. The simple fact that you experience trembling on your Mercedes C class during your acceleration phases, in this scenario you will have to check the state of several components because a good number of elements can be at the beginning of these vibrations and whether or not you are unlucky a combination of several of them may also be possible, here is the list of parts that can be involved.

  • Turbo: If the turbo of your Mercedes C class is defective, it may generate vibrations that you will come to feel when you accelerate at the moment it is activated.
  • The turbo pressure sensor: This sensor will control the pressure exerted in the turbo of your car, if it fails it may disrupt the performance of your turbo and develop vibrations that you may experience during acceleration of your Mercedes C class.

    • .

  • If the turbo is punctured or damaged, the end result will be the same, the power supply of your turbo will be troubled and its performance too. Make sure you visually examine their condition.

We will now look into the scenario where you experience vibrations on your Mercedes C class when you are accelerating but also when you are idling. If you only experience vibrations when you are idling on your Mercedes C class, please read our article focused on this problem to remedy your problem. If, however, you identify that your Mercedes C class vibrates when accelerating but also when it is stopped, here is the list of things to examine:

  • EGR valve: In truth this valve which manages the return of exhaust gases for pollution standards can become dirty and affect the evacuation of exhaust gases which can generate Mercedes C class vibrates when accelerating but also when stopped.
  • Injectors: Your injectors that regulating the fuel/air mixture flow may be dirty or damaged, which will generate the wrong amount of mixture and thus prevent your engine block from working correctly, it is even possible that one or more of your cylinders are not running correctly.
  • Fuel Filter: Like the injectors, if the filter is blocked it will not let the fuel pass correctly and therefore affect the operation of your Mercedes C class, up to the point of causing vibrations during acceleration.

Here are the main causes of a Mercedes C class that vibrates at acceleration

What can I do to stop the vibration when I accelerate on my Mercedes C class? What can I do?

Finally, in this last part, we will give you the answers available to you to overcome these tremors on your car when you accelerate. Here is the best attitude to adopt based on the component that is concerned:

  • Turbo: If your turbo starts all these vibrations when you accelerate your Mercedes C class, it will be good for you to control all the parts linked to it because changing a complete turbo is a big budget and most of the time the problem does not come precisely from the turbo. So make sure you check out your turbo pressure sensor, your flowmeter, the EGR valve and the hoses of your turbo. Otherwise take your Mercedes C class to your mechanic.
  • EGR valve: The EGR valve has the benefit that it is often times easy to access and easy to take apart/clean. You can always examine it and clean it, for this see our article on cleaning the EGR valve of an Mercedes C class.
  • Injectors: Injectors are very delicate parts and a few harmful particles may be enough to affect their operation. Use a fuel additive to simply clean the injectors, if this is not enough you will have to go to a professional.
  • Fuel Filter: If it is the fuel filter, simply replace it. A fuel filter doesn’t clean itself, so if it is clogged you will basically have to replace it with a new one.

Now you have all the info you need to uncover the source of the vibrations at acceleration on your Mercedes C class. If you don’t feel able to conduct certain operations don’t hesitate to go to your auto mechanic.
