Encountering problems on your vehicle is specially bothersome, in addition to the economic side that these concerns represent, one must also add the time lost with a non-operational Audi A7 and the time spent to detect and solve the breakdown. Nevertheless, some problems are less major than others, which is not to say that they do not stress us. Today we are going to look at a trouble that can occur to most of us, perceiving vibrations at acceleration on Audi A7. This trouble can occasionally be complex to perceive but it must be taken care of. We will therefore begin our content with the origins of these vibrations on Audi A7, then, with the solutions you have to reduce or stop these tremors.

Why does my Audi A7 emit vibrations when accelerating?

So let’s begin our content with the origins of this type 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 provoke this form of impression, both at idle and when accelerating.

I feel vibrations on my Audi A7 only when accelerating

Let’s take the most interesting circumstance for us in this content. The simple fact that you experience trembling on your Audi A7 during your acceleration periods, in this situation you will have to examine the state of different components because a good number of elements can be at the origin of these vibrations and even if you are unlucky a mix of several of them may also be possible, here is the list of components that can be concerned.

  • Turbo: If the turbo of your Audi A7 is faulty, it may provoke vibrations that you will come to feel when you accelerate at the moment it is running.
  • The turbo pressure sensor: This sensor will manage 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 at the time of acceleration of your Audi A7.

    • .

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

I’m feeling vibrations on my Audi A7 at acceleration and deceleration

We will now look into the scenario where you come to feel vibrations on your Audi A7 when you are accelerating but also when you are idling. If you only come to feel vibrations when you are idling on your Audi A7, please consult our content focused upon this trouble to remedy your problem. If, alternatively, you detect that your Audi A7 vibrates when accelerating but also when it is stopped, here is the list of elements 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 provoke Audi A7 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 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 blocked it will not let the fuel pass effectively and therefore disrupt the operation of your Audi A7, up to the point of producing vibrations during acceleration.

Here are the most important motives of a Audi A7 that vibrates at acceleration

What can I do to stop the vibration when I accelerate on my Audi A7? What can I do?

Finally, in this last section, we will tell you the answers 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 concerned:

  • Turbo: If your turbo starts all these vibrations when you accelerate your Audi A7, it will be good for you to control all the components connected to it because changing a complete turbo is a big budget and generally the trouble does not come precisely from the turbo. So make sure you check out your turbo pressure sensor, your flowmeter, the EGR valve and the hoses of your turbo. Otherwise take your Audi A7 to your garage.
  • EGR valve: The EGR valve has the benefit that it is generally easy to access and simple to take apart/clean. You can always examine it and clean it, for this see our content on cleaning the EGR valve of an Audi A7.
  • Injectors: Injectors are very fragile components and a few impurities 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 specialist.
  • Fuel Filter: If it is the fuel filter, simply 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 discover the origin of the vibrations at acceleration on your Audi A7. If you don’t feel able to conduct certain operations don’t hesitate to go to your repair shop.
