However, some problems are less significant than others, which is not to say that they do not get worried us. In this article we are going to take a look at a trouble that can happen to many of us, perceiving vibrations at acceleration on Renault Koleos. This trouble can oftentimes be tricky to perceive but it must be looked after. We will therefore begin our article with the origins of these vibrations on Renault Koleos, then, with the answers you have to reduce or stop these tremors.

Why does my Renault Koleos make vibrations when accelerating?

So let’s begin our article with the origins of this form of trouble on your car. You should already know that an engine, specifically 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, specifically those with a lot of torque, can generate this sort of discomfort, both at idle and when accelerating.

I feel vibrations on my Renault Koleos only when accelerating

Let’s take the most interesting case for us in this article. The fact that you feel trembling on your Renault Koleos during your acceleration phases, in this circumstance you will have to check the condition of several elements because several of elements can be at the starting point of these vibrations and even if you are unlucky 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 Renault Koleos is faulty, 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 disrupt the performance of your turbo and bring about vibrations that you may feel within the acceleration of your Renault Koleos.

    • .

  • If the turbo is punctured or ruined, the consequence will be the same, the power supply of your turbo will be troubled and its performance too. Make sure visually verify their condition.

I’m having vibrations on my Renault Koleos at acceleration and deceleration

We will now concentrate on the scenario where you feel vibrations on your Renault Koleos when you are accelerating but also when you are idling. If you only feel vibrations when you are idling on your Renault Koleos, please consult our article focused on this trouble to get rid of your problem. If, on the other hand, you detect that your Renault Koleos 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 generate Renault Koleos vibrates when accelerating but also when stopped.
  • Injectors: Your injectors that regulating 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 effectively.
  • Fuel Filter: Like the injectors, if the filter is clogged it will not let the fuel pass effectively and therefore disturb the performance of your Renault Koleos, up to the point of producing vibrations during acceleration.

Here are the most important triggers of a Renault Koleos that vibrates at acceleration

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

To conclude, in this last section, we will tell you the solutions available to you to cure these tremors on your car when you accelerate. Here is the best attitude to adopt depending on the component that is affected:

  • Turbo: If your turbo starts all these vibrations when you accelerate your Renault Koleos, it will be good for you to control all the parts attached to it because changing a complete turbo is a big budget and typically the trouble does not come exclusively from the turbo. So remember to examine your turbo pressure sensor, your flowmeter, the EGR valve and the hoses of your turbo. Otherwise take your Renault Koleos 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 look into it and clean it, for this see our article on cleaning the EGR valve of an Renault Koleos.
  • Injectors: Injectors are very delicate 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 expert.
  • 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 just have to replace it with a new one.

Now you have all the information you need to discover the source of the vibrations at acceleration on your Renault Koleos. If you don’t feel able to perform certain operations don’t hesitate to go to your technician.
