It is hardly ever pleasurable to experience an injector noise on your Bmw 1 series. It is a noise that happens continually, usually when you accelerate or your engine is idling. However, this symptom may be linked to different types of trouble with your vehicle injectors. It may not be anything severe, but when a repeated noise arises, you have to be sure. Specifically since fixing your Bmw 1 series’s injectors can be costly. That’s why our team decided to compose this content in order to support you see more clearly, learn about the different plausible failures and identify your issue. To do this, we will first look at the normal function and usefulness of the injectors in your Bmw 1 series, then at the plausible reasons from which an injector noise may come.injector-noise-bmw-1-series

Benefits of the injectors

Injectors are a very significant component of the operation of your engine motor. They were introduced to the modern vehicles 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 possibility, thanks to the injectors pump, to control electronically each stage of the intake process very accurately (quantity of fuel injected, air/fuel mixture) via the analysis of the data accumulated from the various sensors equipping the vehicle (engine temperature, acceleration level, engine speed, etc.). Their goal 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 reasons of a clicking or knocking noise coming from the injectors of your Bmw 1 series

Experiencing injector noises on your Bmw 1 series may come from different locations, we will now look into the potential causes of these. In general, the typical noise of a faulty injector is of the snap type. Here are the several sources of these noises and the solutions to be put into practice to prevent them. If you experience another clicking noise but it is not from your injectors, we advise you to browse this content about clicking noise on Bmw 1 series to locate the reason.

The reasons for injector clicking or knocking noise Bmw 1 series

A clicking or knocking noise from your injectors can be explained for different reasons. In fact, the injectors of your Bmw 1 series 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 at last the homogeneity of the mixture, always with the aim of improving combustion. If one of these three features is modified, the main functionality of the injectors will be disrupted and this will lead to poor combustion. This bad combustion will be a violent explosion in the cylinders as a consequence of bad timing, or a bad quantity of mixture or finally an inhomogeneous mixture and will provoke thoses knocking or clicking noises on your Bmw 1 series. The main reason of these concerns generally originates from a particle that gets into the injectors. The precision of the injector being in the nanometer range, any possible obstruction will inevitably lead to a malfunction of the injector. If after verifying, this noise originates from another component of the engine of your Bmw 1 series, have a look at this content for more infos.

The consequences of injector noise on Bmw 1 series

Now that we have reviewed the different reasons for injector noise on your Bmw 1 series, we will end by stating the possible end result of malfunctioning one or more of your injectors. Whether only one is clogged, or damaged, or your entire fuel rail is involved, you cannot escape these side effects which can promptly become serious….
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 regular consequences noticed by drivers is a noticeable loss of power. In fact, if your engine is running on 3 out of 4 cylinders for example, you will surely have a loss of power
Finally, you risk deteriorating one of your pistons or your engine. Poor combustion will promptly harm your cylinders or pistons and your engine may tighten.
Here are three little tips 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 swapping your diesel fuel filter regularly>
