It is never enjoyable to experience an injector noise on your Volkswagen Golf 8. It is a noise that appears frequently, usually when you accelerate or your engine is idling. However, this indicator may be related to several types of trouble with your automobile injectors. It may not be anything serious, but when a repeated noise arises, you have to be sure. Most importantly since fixing your Volkswagen Golf 8’s injectors can be costly. That’s why our team chose to compose this content in order to help you see more clearly, learn about the different possible failures and identify your trouble. To do this, we will first look at the normal function and usefulness of the injectors in your Volkswagen Golf 8, then at the possible reasons from which an injector noise may come.
Functions of the injectors
Injectors are a very useful element of the operation of your engine motor. They were launched to the modern automobiles about 20 years ago. Before their appearance, 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 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 causes of a clicking or knocking noise based on the injectors of your Volkswagen Golf 8
Experiencing injector noises on your Volkswagen Golf 8 may result from different sources, we will now center on the potential causes of these. In general, the regular noise of a faulty injector is of the snap type. Here are the several origins 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 Volkswagen Golf 8 to discover the trigger.
The reasons for injector clicking or knocking noise Volkswagen Golf 8
A clicking or knocking noise from your injectors can be explained for different reasons. Indeed, the injectors of your Volkswagen Golf 8 have three main missions, to manage the vaporisation of the fuel, i.e., to transform the liquid into “gas” during injection, to ease its combustion. Then, its objective is to deal with 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 purpose 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 Golf 8. The main trigger of these trouble generally comes from a particle that gets into the injectors. The precision of the injector being in the nanometer range, any possible blockage will inevitably cause a malfunction of the injector. If after verifying, this noise comes from another component of the engine of your Volkswagen Golf 8, have a look at this content for more informations.
The effects of injector noise on Volkswagen Golf 8
Now that we have examined the diverse causes for injector noise on your Volkswagen Golf 8, we will end by stating the possible consequences 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 effects which can almost instantly become critical….
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 basic consequences noticed by drivers is a severe 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 deteriorating one of your pistons or your engine. Poor combustion will almost instantly affect your cylinders or pistons and your engine may tighten.
Here are three little recommendations to limit the risks connected 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>
