It is hardly ever relaxing to experience an injector noise on your Volkswagen Arteon. It is a noise that arises repeatedly, usually when you accelerate or your engine is idling. However, this sign may be connected to different kind of trouble with your car injectors. It may not be anything serious, but when a repeated noise shows up, you have to be sure. Most importantly since fixing your Volkswagen Arteon’s injectors can be expensive. That’s why our team decided to create this content in order to help you see more clearly, learn about the different plausible failures and identify your trouble. To do this, we will first look at the normal function and usefulness of the injectors in your Volkswagen Arteon, then at the plausible causes from which an injector noise may come.injector-noise-volkswagen-arteon

Functions of the injectors

Injectors are a very useful component of the operation of your engine motor. They were introduced to the modern cars about 20 years ago. Before their arrival, more conventional carburettor-type intake systems were used, 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 collected from the various sensors equipping the car (engine temperature, acceleration level, engine speed, etc.). Their aim 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 Volkswagen Arteon

Listening injector noises on your Volkswagen Arteon may originate from different origins, we will now look into the potential causes of these. In general, the usual noise of a faulty injector is of the snap type. Here are the different sources of these noises and the solutions to be used to eliminate them. If you experience another clicking noise but it is not from your injectors, we recommend you to go through this content about clicking noise on Volkswagen Arteon to find the reason.

The reasons for injector clicking or knocking noise Volkswagen Arteon

A clicking or knocking noise from your injectors can be justified by different reasons. Indeed, the injectors of your Volkswagen Arteon have three main missions, to manage the vaporisation of the fuel, i.e., to convert the liquid into “gas” during injection, to facilitate its combustion. Then, its goal 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 functions is altered, 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 trigger thoses knocking or clicking noises on your Volkswagen Arteon. The main reason of these concerns in most cases originates from a particle that gets into the injectors. The accuracy of the injector being in the nanometer range, any possible obstruction will inevitably end up in a malfunction of the injector.

The repercussions of injector noise on Volkswagen Arteon

Now that we have examined the different causes for injector noise on your Volkswagen Arteon, we will end by stating the possible consequences 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 side effects which can quickly become severe….
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 inevitably have a loss of power
Finally, you risk deteriorating one of your pistons or your engine. Poor combustion will quickly harm your cylinders or pistons and your engine may tighten.
Here are three little tips to limit the risks associated with 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>
