Encountering problems on your motor vehicle is especially bothersome, furthermore the financial burden that these problems signify, one must also add the time lost with a non-operational Audi A4 and the time spent to detect and fix the breakdown. On the other hand, some problems are less significant than others, which is not to say that they do not worry us. On this page we are going to look at a problem that can happen to all of us, feeling vibrations at acceleration on Audi A4. This problem can in some cases be complex to perceive but it must be dealt with. We will therefore begin our guideline with the origins of these vibrations on Audi A4, then, with the solutions you have to reduce or stop these tremors.

Why does my Audi A4 produce vibrations when accelerating?

So let’s begin our guideline with the origins of this form of problem on your car. You should already know that an engine, especially if it is ancient 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 sort of impression, both at idle and when accelerating.

I feel vibrations on my Audi A4 only when accelerating

Let’s take the most interesting case for us in this guideline. The fact that you suffer trembling on your Audi A4 during your acceleration periods, in this scenario you will have to examine the state of several components because several of elements can be at the beginning of these vibrations and regardless if you are unlucky a mix of several of them may also be possible, here is the list of auto parts that can be concerned.

  • Turbo: If the turbo of your Audi A4 is faulty, it may trigger 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 affect the behavior of your turbo and generate vibrations that you may come to feel within the acceleration of your Audi A4.
  • .

  • If the turbo is punctured or damaged, the consequence will be similar, the power supply of your turbo will be disrupted and its behavior too. Be sure to visually check their state.

I’m feeling vibrations on my Audi A4 at acceleration and deceleration

We will now concentrate on the scenario where you come to feel vibrations on your Audi A4 when you are accelerating but also when you are idling. If you only come to feel vibrations when you are idling on your Audi A4, please seek advice from our guideline focused on this problem to remedy your problem. If, alternatively, you realize that your Audi A4 vibrates when accelerating but also when it is stopped, here is the list of items to check:

  • EGR valve: In truth this valve which manages the return of exhaust gases for pollution standards can become dirty and disturb the evacuation of exhaust gases which can trigger Audi A4 vibrates when accelerating but also when stopped.
  • Injectors: Your injectors that control the fuel/air mixture flow may be dirty or damaged, which will bring out 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 clogged it will not let the fuel pass properly and therefore disturb the performance of your Audi A4, up to the point of leading to vibrations during acceleration.

Here are the most important triggers of a Audi A4 that vibrates at acceleration

What can I do to stop the vibration when I accelerate on my Audi A4? What can I do?

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

  • Turbo: If your turbo starts all these vibrations when you accelerate your Audi A4, it will be good for you to control all the auto parts associated with it because changing a complete turbo is a big budget and generally the problem does not come precisely from the turbo. So be sure to take a look at your turbo pressure sensor, your flowmeter, the EGR valve and the hoses of your turbo. Otherwise take your Audi A4 to your garage.
  • EGR valve: The EGR valve has the benefit that it is more often than not easy to access and simple to disassemble/clean. You can always take a look at it and clean it, for this see our guideline on cleaning the EGR valve of an Audi A4.
  • Injectors: Injectors are very sensitive auto parts and a few harmful particles may be enough to disturb 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 basically have to replace it with a new one.

Now you have all the information you need to discover the cause of the vibrations at acceleration on your Audi A4. If you don’t feel able to accomplish certain operations don’t hesitate to go to your technician.
