In this article we are going to check out a problem that can occur to everyone, having vibrations at acceleration on Opel Zafira. This problem can oftentimes be difficult to perceive but it must be dealt with. We will therefore commence our guideline with the origins of these vibrations on Opel Zafira, then, with the solutions you have to reduce or stop these tremors.

Why does my Opel Zafira make vibrations when accelerating?

So let’s commence our guideline with the origins of this type of problem on your car. You should already know that an engine, specifically if it is old or if it has been driven a lot, can naturally vibrate without being a problem 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 Opel Zafira only when accelerating

Let’s take the most interesting case for us in this guideline. The simple fact that you undergo trembling on your Opel Zafira during your acceleration periods, in this scenario you will have to verify the state of some components because various of elements can be at the source of these vibrations and regardless if you are unfortunate a combination of several of them may also be possible, here is the list of components that can be concerned.

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

    • .

  • If the turbo is punctured or ruined, the result will be the same, the power supply of your turbo will be disrupted and its performance too. Remember to visually check their state.

I’m feeling vibrations on my Opel Zafira at acceleration and deceleration

We will now focus on the scenario where you experience vibrations on your Opel Zafira when you are accelerating but also when you are idling. If you only experience vibrations when you are idling on your Opel Zafira, please seek advice from our guideline focused on this problem to remedy your problem. If, on the other hand, you detect that your Opel Zafira vibrates when accelerating but also when it is stopped, here is the list of elements to check:

  • EGR valve: In reality this valve which manages the return of exhaust gases for pollution standards can become dirty and disturb the evacuation of exhaust gases which can generate Opel Zafira 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 properly, 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 disturb the performance of your Opel Zafira, up to the point of causing vibrations during acceleration.

Here are the most important triggers of a Opel Zafira that vibrates at acceleration

What can I do to stop the vibration when I accelerate on my Opel Zafira? What can I do?

To finish , in this last section, 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 based on the part that is affected:

  • Turbo: If your turbo starts all these vibrations when you accelerate your Opel Zafira, it will be good for you to control all the components associated with it because changing a complete turbo is a big budget and generally the problem does not come exclusively from the turbo. So be sure to take a look at your turbo pressure sensor, your flowmeter, the EGR valve and the hoses of your turbo. Otherwise take your Opel Zafira to your garage area.
  • EGR valve: The EGR valve has the benefit that it is quite often easy to access and simple to disassemble/clean. You can always check out it and clean it, for this see our guideline on cleaning the EGR valve of an Opel Zafira.
  • Injectors: Injectors are very delicate components 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, simply 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.

Now you have all the info you need to locate the source of the vibrations at acceleration on your Opel Zafira. If you don’t feel able to execute certain operations don’t hesitate to go to your auto mechanic.
