Why does my Audi A3 make vibrations when accelerating?

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

I feel vibrations on my Audi A3 only when accelerating

Let’s take the most interesting case for us in this content. The simple fact that you experience trembling on your Audi A3 during your acceleration phases, in this situation you will have to verify the state of several components because several of elements can be at the starting point of these vibrations and even if you are unfortunate a combination of several of them may also be possible, here is the list of parts that can be concerned.

  • Turbo: If the turbo of your Audi A3 is defective, it may generate vibrations that you will suffer when you accelerate at the moment it is turned on.
  • 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 bring about vibrations that you may experience during acceleration of your Audi A3.
  • .

  • If the turbo is punctured or injured, the end result will be the same, the power supply of your turbo will be disturbed and its behavior too. Be sure to visually verify their condition.

I’m having vibrations on my Audi A3 at acceleration and deceleration

We will now focus on the situation where you experience vibrations on your Audi A3 when you are accelerating but also when you are idling. If you only experience vibrations when you are idling on your Audi A3, please read our content dedicated to this trouble to resolve your problem. If, however, you notice that your Audi A3 vibrates when accelerating but also when it is stopped, here is the list of things to verify:

  • EGR valve: In truth this valve which handles the return of exhaust gases for pollution standards can become dirty and affect the evacuation of exhaust gases which can generate Audi A3 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 effectively.
  • Fuel Filter: Like the injectors, if the filter is clogged it will not let the fuel pass effectively and therefore affect the performance of your Audi A3, up to the point of leading to vibrations during acceleration.

Here are the most important causes of a Audi A3 that vibrates at acceleration

What can I do to stop the vibration when I accelerate on my Audi A3? What can I do?

Finally, in this last section, we will tell you the solutions available to you to get over these tremors on your car when you accelerate. Here is the best attitude to adopt in accordance with the component that is involved:

  • Turbo: If your turbo starts all these vibrations when you accelerate your Audi A3, it will be good for you to control all the parts associated with it because changing a complete turbo is a big budget and generally the trouble does not come directly from the turbo. So be sure to check out your turbo pressure sensor, your flowmeter, the EGR valve and the hoses of your turbo. Otherwise take your Audi A3 to your mechanic.
  • 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 check out it and clean it, for this see our content on cleaning the EGR valve of an Audi A3.
  • Injectors: Injectors are very fragile parts and a few impurities may be enough to affect 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, only 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 info you need to find the origin of the vibrations at acceleration on your Audi A3. If you don’t feel able to do certain operations don’t hesitate to go to your mechanic.
