Why does my BMW 3 Series make vibrations when accelerating?

So let’s begin our guideline with the roots of this form of problem on your car.

Large diesel engines, specifically those with a lot of torque, can bring about this form of sensation, both at idle and when accelerating.

I feel vibrations on my BMW 3 Series only when accelerating

Let’s take the most interesting circumstance for us in this guideline. The fact that you undergo trembling on your BMW 3 Series during your acceleration phases, in this scenario you will have to check the state of different parts because a good number of elements can be at the beginning of these vibrations and whether or not you are unlucky 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 3 Series is defective, it may bring about 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 behavior of your turbo and deliver vibrations that you may come to feel at the time of acceleration of your BMW 3 Series.

We will now concentrate on the situation where you come to feel vibrations on your BMW 3 Series when you are accelerating but also when you are idling. If you only come to feel vibrations when you are idling on your BMW 3 Series, please consult our guideline dedicated to this problem to get rid of your problem. If, alternatively, you detect that your BMW 3 Series vibrates when accelerating but also when it is stopped, here is the list of things to check:

  • EGR valve: In truth this valve which controls the return of exhaust gases for pollution standards can become dirty and affect the evacuation of exhaust gases which can bring about BMW 3 Series 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 properly.
  • Fuel Filter: Like the injectors, if the filter is blocked it will not let the fuel pass properly and therefore affect the operation of your BMW 3 Series, up to the point of leading to vibrations during acceleration.

So make sure take a look at your turbo pressure sensor, your flowmeter, the EGR valve and the hoses of your turbo. Otherwise take your BMW 3 Series to your garage.
  • EGR valve: The EGR valve has the advantage that it is 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 BMW 3 Series.
  • Injectors: Injectors are very sensitive auto parts and a few impurities may be enough to affect their operation. 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 just have to replace it with a new one.
