Being the target of recurring problems on your motor vehicle is particularly bothersome, moreover the economic burden that these complications represent, one must also add the time lost with a non-operational Mercedes Classe C and the time spent to identify and remedy the malfunction. However, some problems are less significant than others, which is not to say that they do not stress us. In this article we are going to look into a problem that can occur to most of us, having vibrations at acceleration on Mercedes Classe C. This problem can sometimes be tricky to perceive but it must be looked after. We will therefore commence our guideline with the origins of these vibrations on Mercedes Classe C, then, with the answers you have to reduce or stop these tremors.

Why does my Mercedes Classe C produce vibrations when accelerating?

So let’s commence our guideline with the origins of this sort of problem on your car. You should already know that an engine, especially if it is old or if it has been driven quite a bit, can naturally vibrate without being a problem behind it. Large diesel engines, especially those with a lot of torque, can trigger this form of impression, both at idle and when accelerating.

I feel vibrations on my Mercedes Classe C only when accelerating

Let’s take the most interesting circumstance for us in this guideline. The simple fact that you suffer trembling on your Mercedes Classe C during your acceleration periods, in this situation you will have to verify the state of some components because a good number of elements can be at the source of these vibrations and even if you are unlucky a combination of several of them may also be possible, here is the list of auto parts that can be involved.

  • Turbo: If the turbo of your Mercedes Classe C is defective, it may trigger vibrations that you will feel when you accelerate at the moment it is activated.
  • The turbo pressure sensor: This sensor will manage the pressure exerted in the turbo of your car, if it fails it may affect the performance of your turbo and deliver vibrations that you may experience within the acceleration of your Mercedes Classe C.

    • .

  • If the turbo is punctured or injured, the result will be similar, the power supply of your turbo will be disrupted and its performance too. Be sure to visually examine their state.

I’m experiencing vibrations on my Mercedes Classe C at acceleration and deceleration

We will now focus on the scenario where you experience vibrations on your Mercedes Classe C when you are accelerating but also when you are idling. If you only experience vibrations when you are idling on your Mercedes Classe C, please read our guideline focused upon this problem to resolve your problem. If, alternatively, you realize that your Mercedes Classe C vibrates when accelerating but also when it is stopped, here is the list of things to examine:

  • EGR valve: In actual fact this valve which manages the return of exhaust gases for pollution standards can become dirty and disrupt the evacuation of exhaust gases which can trigger Mercedes Classe C vibrates when accelerating but also when stopped.
  • Injectors: Your injectors that control 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 effectively, it is even possible that one or more of your cylinders are not running effectively.
  • Fuel Filter: Like the injectors, if the filter is clogged it will not let the fuel pass effectively and therefore disrupt the operation of your Mercedes Classe C, up to the point of causing vibrations during acceleration.

Here are the main motives of a Mercedes Classe C that vibrates at acceleration

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

To conclude, in this last section, we will tell you the solutions available to you to overcome these tremors on your car when you accelerate. Here is the best attitude to adopt depending on the component that is concerned:

  • Turbo: If your turbo starts all these vibrations when you accelerate your Mercedes Classe C, it will be good for you to control all the auto parts linked to it because changing a complete turbo is a big budget and in most cases the problem does not come exclusively from the turbo. So remember to take a look at your turbo pressure sensor, your flowmeter, the EGR valve and the hoses of your turbo. Otherwise take your Mercedes Classe C to your mechanic.
  • EGR valve: The EGR valve has the benefit that it is often easy to access and simple to disassemble/clean. You can always look into it and clean it, for this see our guideline on cleaning the EGR valve of an Mercedes Classe C.
  • Injectors: Injectors are very sensitive auto parts and a few harmful particles may be enough to disrupt their operation. Use a fuel additive to simply clean the injectors, if this is not enough you will have to go to a expert.
  • Fuel Filter: If it is the fuel filter, only replace it. A fuel filter doesn’t clean itself, so if it is clogged you will only have to replace it with a new one.

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