Large diesel engines, especially those with a lot of torque, can generate this form of sensation, both at idle and when accelerating.

I feel vibrations on my Audi A5 only when accelerating

Let’s take the most interesting circumstance for us in this guideline. The simple fact that you feel trembling on your Audi A5 during your acceleration phases, in this circumstance you will have to verify the condition of different components because a good number of elements can be at the source of these vibrations and whether or not 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 A5 is defective, it may generate 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 disturb the behavior of your turbo and create vibrations that you may come to feel at the time of acceleration of your Audi A5.

If, however, you notice that your Audi A5 vibrates when accelerating but also when it is stopped, here is the list of elements to examine:

  • EGR valve: In fact this valve which controls the return of exhaust gases for pollution standards can become dirty and bother the evacuation of exhaust gases which can generate Audi A5 vibrates when accelerating but also when stopped.
  • Injectors: Your injectors that control the fuel/air mixture flow may be dirty or damaged, which will generate 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 bother the performance of your Audi A5, up to the point of causing vibrations during acceleration.

Here are the most important triggers of a Audi A5 that vibrates at acceleration

To conclude, in this last section, we will provide you the answers available to you to cure these tremors on your car when you accelerate. Here is the best attitude to adopt based on the component that is involved:

So make sure take a look at your turbo pressure sensor, your flowmeter, the EGR valve and the hoses of your turbo. Otherwise take your Audi A5 to your garage.
  • EGR valve: The EGR valve has the benefit that it is often easy to access and easy to take apart/clean. You can always examine it and clean it, for this see our guideline on cleaning the EGR valve of an Audi A5.
  • Injectors: Injectors are very fragile parts and a few harmful particles may be enough to bother 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.
