Why does my Mercedes Classe A 4 emit vibrations when accelerating?

So let’s commence our content with the sources 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 generate this form of discomfort, both at idle and when accelerating.

I feel vibrations on my Mercedes Classe A 4 only when accelerating

Let’s take the most interesting circumstance for us in this content. The fact that you come to feel trembling on your Mercedes Classe A 4 during your acceleration periods, in this circumstance you will have to verify the condition of several components because several of elements can be at the source 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 components that can be involved.

  • Turbo: If the turbo of your Mercedes Classe A 4 is faulty, it may generate vibrations that you will feel when you accelerate at the moment it is running.
  • The turbo pressure sensor: This sensor will control the pressure exerted in the turbo of your car, if it fails it may disturb the performance of your turbo and generate vibrations that you may feel at the time of acceleration of your Mercedes Classe A 4.

  • If the turbo is punctured or ruined, the result will be the same, the power supply of your turbo will be disturbed and its performance too. Make sure visually verify their condition.

I’m getting vibrations on my Mercedes Classe A 4 at acceleration and deceleration

We will now look into the situation where you feel vibrations on your Mercedes Classe A 4 when you are accelerating but also when you are idling. If you only feel vibrations when you are idling on your Mercedes Classe A 4, please read our content focused upon this problem to fix your problem. If, however, you identify that your Mercedes Classe A 4 vibrates when accelerating but also when it is stopped, here is the list of items to verify:

  • EGR valve: In fact this valve which controls the return of exhaust gases for pollution standards can become dirty and disrupt the evacuation of exhaust gases which can generate Mercedes Classe A 4 vibrates when accelerating but also when stopped.
  • Injectors: Your injectors that control the fuel/air mixture flow may be dirty or damaged, which will discharge 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 properly.
  • Fuel Filter: Like the injectors, if the filter is clogged it will not let the fuel pass properly and therefore disrupt the performance of your Mercedes Classe A 4, up to the point of leading to vibrations during acceleration.

Here are the most important motives of a Mercedes Classe A 4 that vibrates at acceleration

What can I do to stop the vibration when I accelerate on my Mercedes Classe A 4? What can I do?

To finish , in this last part, 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 involved:

  • Turbo: If your turbo starts all these vibrations when you accelerate your Mercedes Classe A 4, it will be good for you to control all the components attached to it because changing a complete turbo is a big budget and in most cases the problem does not come specifically from the turbo. So remember to check out your turbo pressure sensor, your flowmeter, the EGR valve and the hoses of your turbo. Otherwise take your Mercedes Classe A 4 to your garage area.
  • 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 check out it and clean it, for this see our content on cleaning the EGR valve of an Mercedes Classe A 4.
  • Injectors: Injectors are very fragile components and a few harmful particles may be enough to disrupt their performance. 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, just 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 source of the vibrations at acceleration on your Mercedes Classe A 4. If you don’t feel able to complete certain procedures don’t hesitate to go to your auto technician.
