Your car is shaking and losing power, you think it can stall at any time? This little trouble sometimes happens on a BMW 4 Series and it is necessary to identify the reason because it can have more serious consequences in the future. In this article, we will try to give you an answer and identify all the potential causes that can make your BMW 4 Series shake.


Factors that makes your BMW 4 Series shake


The first thing to do as an analysis on your BMW 4 Series is to clean the various parts. Indeed, dirty parts can provoke acceleration problems. So check your filters, as air and fuel go through this path before attaining the injectors. If the road was blocked, think of it as a blocked highway, everything is slowed down. Clean them, and if they are too old, it is reasonable to change them.

Injectors of your BMW 4 Series:

Directly related to these filters, the injectors obtain the fuel through the filters, and then supply the combustion chamber, where the spark plugs ignite the fuel, which enables your BMW 4 Series to move forward thanks to this process. If you had poor quality fuel or simply fouling at this level, the pressure of the injection pump could be damaged, and therefore combustion would no longer be correct. Of course, this will be experienced in the acceleration of your BMW 4 Series.


As described above, the spark plugs ignite the fuel once it reaches the combustion chamber. If it hasn’t had any problems so far, maybe that’s where it comes from. If the spark plugs are faulty and have difficulties igniting the fuel, you will have trouble driving gently with your BMW 4 Series. Check them and change them if necessary.

Hoses of your BMW 4 Series:

In your BMW 4 Series, you have small hoses that are similar to small pipes that also allow the transport of different fluids. They must absolutely remain waterproof, otherwise you will also find yourself shaking because the fuel or oxygen supply will not be heterogeneous.


Another point to check if the BMW 4 Series shakes is the calculator. This one is accountable for the ignition but also for the injection. It sends orders electronically to ensure that this task is completed. Imagine a conductor giving inconsistent instructions to the orchestra, it would end into a rather chaotic situation. The same is true for your BMW 4 Series, which would end up shaking. If the calculator is involved , it becomes more tough to manage yourself. It is more reasonable to go to a garage to have it recalibrated or replaced if it is not repairable.

Conclusion :

Here are the main motives that could cause your BMW 4 Series to shake. It is necessary to note that it is often dirty and generally poorly maintained parts that will cause this. Try to regularly check on the inside of your BMW 4 Series by cleaning what you can.
