It is rarely ever enjoyable to listen an injector noise on your Bmw Serie 4 F33. It is a noise that comes up continually, usually when you accelerate or your engine is idling. However, this indication may be connected to several types of complications with your automobile injectors. It may not be anything serious, but when a persistent noise appears, you have to be sure. Especially since replacing your Bmw Serie 4 F33’s injectors can be expensive. That’s why our team chose to write this article in order to support you see more clearly, learn about the different plausible failures and identify your trouble. To do this, we will first look at the normal functioning and usefulness of the injectors in your Bmw Serie 4 F33, then at the plausible causes from which an injector noise may come.injector-noise-bmw-serie-4-f33

Purposes of the injectors

Injectors are a very useful part of the operation of your engine. They were released to the modern cars about 20 years ago. Before their introduction, more conventional carburettor-type intake systems were employed, which handled the intake of air and fuel into the engine cylinders. With the injectors, manufacturers now have the opportunity, thanks to the injectors pump, to control electronically each stage of the intake process very precisely (quantity of fuel injected, air/fuel mixture) via the analysis of the data collected from the various sensors equipping the automobile (engine temperature, acceleration level, engine speed, etc.). Their purpose is therefore to inject under high pressure a precise quantity of an air/fuel mixture at a perfect timing to obtain the best possible combustion in the cylinders.

The different triggers of a clicking or knocking noise based on the injectors of your Bmw Serie 4 F33

Finding out injector noises on your Bmw Serie 4 F33 may result from different sources, we will now focus on the potential causes of these. In general, the usual noise of a faulty injector is of the snap type. Here are the several origins of these noises and the solutions to be used to prevent them. If you listen another clicking noise but it is not from your injectors, we recommend you to go through this article about clicking noise on Bmw Serie 4 F33 to locate the trigger.

The causes for injector clicking or knocking noise Bmw Serie 4 F33

A clicking or knocking noise from your injectors can be justified by different causes. Indeed, the injectors of your Bmw Serie 4 F33 have three main missions, to control the vaporisation of the fuel, i.e., to transform the liquid into “gas” during injection, to facilitate its combustion. Then, its mission is to control the air/fuel dosage and finally the homogeneity of the mixture, always with the target of improving combustion. If one of these three attributes is altered, the main purpose of the injectors will be disrupted and this will lead to poor combustion. This bad combustion will be a violent explosion in the cylinders resulting from bad timing, or a bad quantity of mixture or finally an inhomogeneous mixture and will induce thoses knocking or clicking noises on your Bmw Serie 4 F33. The main trigger of these problems usually originates from a particle that gets into the injectors. The accuracy of the injector being in the nanometer range, any possible blockage will inevitably end up in a malfunction of the injector.

The effects of injector noise on Bmw Serie 4 F33

Now that we have analyzed the several reasons for injector noise on your Bmw Serie 4 F33, we will end by stating the possible side effects of malfunctioning one or more of your injectors. Whether only one is blocked, or damaged, or your entire fuel rail is involved, you cannot escape these effects which can fairly quickly become major….
First, you risk destroying your exhaust system in the long run, because the unburned fuel residues that will end up in your exhaust system can corrode the metal in it.
One of the most common repercussions experienced by drivers is a significant loss of power. Indeed, if your engine is running on 3 out of 4 cylinders for example, you will undoubtedly have a loss of power
Finally, you risk degrading one of your pistons or your engine. Poor combustion will fairly quickly harm your cylinders or pistons and your engine may tighten.
Here are three little suggestions to limit the risks relating to your injectors and protect you from engine failure:

  • Do not drive at the bottom of the tank, as you may absorb impurities
  • Use quality fuel
  • Think of changing your diesel fuel filter regularly>
