Why does my Mercedes Classe A produce vibrations when accelerating?

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

I feel vibrations on my Mercedes Classe A only when accelerating

Let’s take the most interesting case for us in this article. The fact that you undergo trembling on your Mercedes Classe A during your acceleration periods, in this circumstance you will have to verify the state of different components because many of elements can be at the beginning of these vibrations and whether or not you are unlucky a mix 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 Classe A is faulty, it may trigger 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 disrupt the behavior of your turbo and make vibrations that you may come to feel during acceleration of your Mercedes Classe A.

    • .

  • If the turbo is punctured or harmed, the end result will be alike, the power supply of your turbo will be disturbed and its behavior too. Make sure visually examine their condition.

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

We will now concentrate on the situation where you come to feel vibrations on your Mercedes Classe A when you are accelerating but also when you are idling. If you only come to feel vibrations when you are idling on your Mercedes Classe A, please read our article focused upon this problem to solve your problem. If, alternatively, you realize that your Mercedes Classe A vibrates when accelerating but also when it is stopped, here is the list of elements to examine:

  • EGR valve: In truth 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 A 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 properly, it is even possible that one or more of your cylinders are not running properly.
  • Fuel Filter: Like the injectors, if the filter is blocked it will not let the fuel pass properly and therefore disrupt the performance of your Mercedes Classe A, up to the point of causing vibrations during acceleration.

Here are the main triggers of a Mercedes Classe A that vibrates at acceleration

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

To conclude, in this last section, we will give you the possibilities available to you to handle these tremors on your car when you accelerate. Here is the best attitude to adopt according to the part that is involved:

  • Turbo: If your turbo starts all these vibrations when you accelerate your Mercedes Classe A, it will be good for you to control all the parts attached 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 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 to your garage area.
  • EGR valve: The EGR valve has the advantage that it is quite often easy to access and easy to take apart/clean. You can always take a look at it and clean it, for this see our article on cleaning the EGR valve of an Mercedes Classe A.
  • Injectors: Injectors are very fragile parts and a few impurities 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 specialist.
  • Fuel Filter: If it is the fuel filter, just change it. A fuel filter doesn’t clean itself, so if it is clogged you will simply have to replace it with a new one.

Now you have all the information you need to locate the source of the vibrations at acceleration on your Mercedes Classe A. If you don’t feel able to perform certain procedures don’t hesitate to go to your technician.
