Why does my Peugeot 407 produce vibrations when accelerating?

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

Let’s take the most interesting case for us in this guideline. The fact that you undergo trembling on your Peugeot 407 during your acceleration periods, in this circumstance you will have to examine the condition of several components because various of elements can be at the starting point of these vibrations and regardless if you are unfortunate a combination of several of them may also be possible, here is the list of parts that can be involved.

  • Turbo: If the turbo of your Peugeot 407 is faulty, it may cause vibrations that you will feel when you accelerate at the moment it is turned on.
  • The turbo pressure sensor: This sensor will manage the pressure exerted in the turbo of your car, if it fails it may affect the behavior of your turbo and deliver vibrations that you may experience during acceleration of your Peugeot 407.

I’m getting vibrations on my Peugeot 407 at acceleration and deceleration

We will now focus on the situation where you experience vibrations on your Peugeot 407 when you are accelerating but also when you are idling. If you only experience vibrations when you are idling on your Peugeot 407, please seek advice from our guideline focused upon this issue to get rid of your problem. If, however, you notice that your Peugeot 407 vibrates when accelerating but also when it is stopped, here is the list of things to verify:

  • EGR valve: In truth this valve which controls the return of exhaust gases for pollution standards can become dirty and disturb the evacuation of exhaust gases which can cause Peugeot 407 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 correctly, 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 Peugeot 407, up to the point of causing vibrations during acceleration.

Here are the most important causes of a Peugeot 407 that vibrates at acceleration

What can I do to stop the vibration when I accelerate on my Peugeot 407? 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 depending on the component that is concerned:

  • Turbo: If your turbo starts all these vibrations when you accelerate your Peugeot 407, it will be good for you to control all the parts connected to it because changing a complete turbo is a big budget and typically the issue does not come specifically from the turbo. So make sure you take a look at your turbo pressure sensor, your flowmeter, the EGR valve and the hoses of your turbo. Otherwise take your Peugeot 407 to your garage area.
  • EGR valve: The EGR valve has the benefit that it is quite often easy to access and easy to disassemble/clean. You can always check out it and clean it, for this see our guideline on cleaning the EGR valve of an Peugeot 407.
  • Injectors: Injectors are very fragile 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, only replace it. A fuel filter doesn’t clean itself, so if it is clogged you will just have to replace it with a new one.

Now you have all the info you need to uncover the origin of the vibrations at acceleration on your Peugeot 407. If you don’t feel able to do certain procedures don’t hesitate to go to your mechanic.
