Why does my BMW 4 Series produce vibrations when accelerating?

So let’s start our content with the roots of this form of issue on your car. You should already know that an engine, specifically if it is ancient or if it has been driven quite a bit, can naturally vibrate without being a issue behind it. Large diesel engines, specifically those with a lot of torque, can generate this form of discomfort, both at idle and when accelerating.

I feel vibrations on my BMW 4 Series only when accelerating

Let’s take the most interesting case for us in this content. The fact that you suffer trembling on your BMW 4 Series during your acceleration phases, in this circumstance you will have to verify the state of different elements because many of elements can be at the starting point 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 BMW 4 Series 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 manage the pressure exerted in the turbo of your car, if it fails it may disturb the behavior of your turbo and develop vibrations that you may experience within the acceleration of your BMW 4 Series.

  • If the turbo is punctured or damaged, the end result will be alike, the power supply of your turbo will be disrupted and its behavior too. Make sure you visually check their condition.

I’m experiencing vibrations on my BMW 4 Series at acceleration and deceleration

We will now focus on the scenario where you experience vibrations on your BMW 4 Series when you are accelerating but also when you are idling. If you only experience vibrations when you are idling on your BMW 4 Series, please seek advice from our content focused upon this issue to fix your problem. If, on the other hand, you detect that your BMW 4 Series vibrates when accelerating but also when it is stopped, here is the list of items to check:

  • EGR valve: In 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 generate BMW 4 Series 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 operation of your BMW 4 Series, up to the point of leading to vibrations during acceleration.

Here are the main causes of a BMW 4 Series that vibrates at acceleration

What can I do to stop the vibration when I accelerate on my BMW 4 Series? What can I do?

To finish , in this last part, we will give you the answers available to you to cure these tremors on your car when you accelerate. Here is the best attitude to adopt dependent on the component that is concerned:

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 BMW 4 Series to your mechanic.
  • EGR valve: The EGR valve has the advantage that it is generally easy to access and simple to take apart/clean. You can always take a look at it and clean it, for this see our content on cleaning the EGR valve of an BMW 4 Series.
  • Injectors: Injectors are very delicate auto parts and a few impurities may be enough to disrupt their operation. Use a fuel additive to simply clean the injectors, if this is not enough you will have to go to a specialist.
  • 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 only have to replace it with a new one.

Now you have all the information you need to find the origin of the vibrations at acceleration on your BMW 4 Series. If you don’t feel able to perform certain operations don’t hesitate to go to your auto mechanic.
