Why does my Renault Grand Modus release vibrations when accelerating?

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

I feel vibrations on my Renault Grand Modus only when accelerating

Let’s take the most interesting case for us in this guideline. The fact that you feel trembling on your Renault Grand Modus during your acceleration periods, in this situation you will have to verify the state of different components because many of elements can be at the source of these vibrations and regardless if you are unfortunate a mix of several of them may also be possible, here is the list of auto parts that can be involved.

  • Turbo: If the turbo of your Renault Grand Modus is defective, it may cause vibrations that you will suffer when you accelerate at the moment it is activated.
  • The turbo pressure sensor: This sensor will manage the pressure exerted in the turbo of your car, if it fails it may bother the performance of your turbo and generate vibrations that you may feel within the acceleration of your Renault Grand Modus.

    • .

  • If the turbo is punctured or harmed, the end result will be alike, the power supply of your turbo will be disturbed and its performance too. Be sure to visually check their state.

I’m experiencing vibrations on my Renault Grand Modus at acceleration and deceleration

We will now concentrate on the scenario where you feel vibrations on your Renault Grand Modus when you are accelerating but also when you are idling. If you only feel vibrations when you are idling on your Renault Grand Modus, please have a look at our guideline dedicated to this issue to resolve your problem. If, on the other hand, you realize that your Renault Grand Modus vibrates when accelerating but also when it is stopped, here is the list of elements to check:

  • EGR valve: In actual fact this valve which manages the return of exhaust gases for pollution standards can become dirty and disrupt the evacuation of exhaust gases which can cause Renault Grand Modus 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 correctly, it is even possible that one or more of your cylinders are not running correctly.
  • Fuel Filter: Like the injectors, if the filter is blocked it will not let the fuel pass correctly and therefore disrupt the performance of your Renault Grand Modus, up to the point of generating vibrations during acceleration.

Here are the most important motives of a Renault Grand Modus that vibrates at acceleration

What can I do to stop the vibration when I accelerate on my Renault Grand Modus? What can I do?

To conclude, in this last part, we will give you the answers available to you to overcome these tremors on your car when you accelerate. Here is the best attitude to adopt depending on the component that is involved:

  • Turbo: If your turbo starts all these vibrations when you accelerate your Renault Grand Modus, it will be good for you to control all the auto parts connected to it because changing a complete turbo is a big budget and typically the issue does not come precisely from the turbo. So make sure you examine your turbo pressure sensor, your flowmeter, the EGR valve and the hoses of your turbo. Otherwise take your Renault Grand Modus to your workshop.
  • EGR valve: The EGR valve has the advantage that it is often times easy to access and easy to disassemble/clean. You can always examine it and clean it, for this see our guideline on cleaning the EGR valve of an Renault Grand Modus.
  • Injectors: Injectors are very sensitive auto parts and a few harmful particles may be enough to disrupt their performance. Use a fuel additive to simply clean the injectors, if this is not enough you will have to go to a expert.
  • 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 basically have to replace it with a new one.

Now you have all the info you need to discover the cause of the vibrations at acceleration on your Renault Grand Modus. If you don’t feel able to accomplish certain procedures don’t hesitate to go to your repair shop.
