It is hardly ever pleasant to experience an injector noise on your Volkswagen Coccinelle. It is a noise that happens regularly, usually when you accelerate or your engine is idling. However, this sign may be connected to different kind of problems with your automobile injectors. It may not be anything major, but when a repeated noise shows up, you have to be sure. Specifically since replacing your Volkswagen Coccinelle’s injectors can be costly. That’s why our team chose to create this article content in order to help you see more clearly, learn about the different possible failures and distinguish your trouble. To do this, we will first look at the normal function and usefulness of the injectors in your Volkswagen Coccinelle, then at the possible reasons from which an injector noise may come.injector-noise-volkswagen-coccinelle

Functions of the injectors

Injectors are a very fundamental part of the operation of your engine motor. They were launched to the modern vehicles 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 ability, 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 automobile (engine temperature, acceleration level, engine speed, etc.). Their objective 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 based on the injectors of your Volkswagen Coccinelle

Finding out injector noises on your Volkswagen Coccinelle may result from different sources, we will now focus on the potential triggers of these. In most cases, the regular noise of a faulty injector is of the snap type. Here are the several sources of these noises and the solutions to be applied to eliminate them. If you experience another clicking noise but it is not from your injectors, we encourage you to examine this article content about clicking noise on Volkswagen Coccinelle to locate the trigger.

The reasons for injector clicking or knocking noise Volkswagen Coccinelle

A clicking or knocking noise from your injectors can be explained for different reasons. In fact, the injectors of your Volkswagen Coccinelle have three main missions, to manage the vaporisation of the fuel, i.e., to convert the liquid into “gas” during injection, to ease its combustion. Then, its goal is to manage the air/fuel dosage and at last the homogeneity of the mixture, always with the objective of improving combustion. If one of these three features is modified, the main functionality of the injectors will be disturbed 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 induce thoses knocking or clicking noises on your Volkswagen Coccinelle. The main trigger of these situations commonly originates from a particle that gets into the injectors. The accuracy of the injector being in the nanometer range, any possible blockage will inevitably cause a malfunction of the injector. If after verifying, this noise originates from another part of the engine of your Volkswagen Coccinelle, check this article content for more infos.

The repercussions of injector noise on Volkswagen Coccinelle

Now that we have analyzed the several reasons for injector noise on your Volkswagen Coccinelle, we will end by stating the possible end result 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 known consequences experienced by drivers is a serious loss of power. In fact, 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 affect 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>
