It is hardly ever pleasant to acknowledge an injector noise on your Volkswagen Golf 6. It is a noise that appears continually, usually when you accelerate or your engine is idling. However, this indication may be related to different sort of trouble with your automobile injectors. It may not be anything major, but when a persistent noise shows up, you have to be sure. Specifically since repairing your Volkswagen Golf 6’s injectors can be costly. That’s why our team decided to create this article content in order to support you see more clearly, learn about the different conceivable failures and establish your problem. To do this, we will first look at the normal functioning and usefulness of the injectors in your Volkswagen Golf 6, then at the conceivable triggers from which an injector noise may come.
Functions of the injectors
Injectors are a very useful part of the operation of your engine motor. They were released 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 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 received 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 coming from the injectors of your Volkswagen Golf 6
Experiencing injector noises on your Volkswagen Golf 6 may result from different sources, we will now concentrate on the potential causes of these. In general, the common noise of a faulty injector is of the snap type. Here are the several sources of these noises and the solutions to be adopted to get rid of them. If you acknowledge another clicking noise but it is not from your injectors, we suggest you to read this article content about clicking noise on Volkswagen Golf 6 to locate the cause.
The explanations for injector clicking or knocking noise Volkswagen Golf 6
A clicking or knocking noise from your injectors can be explained for different explanations. Indeed, the injectors of your Volkswagen Golf 6 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 deal with the air/fuel dosage and finally the homogeneity of the mixture, always with the objective of improving combustion. If one of these three characteristics 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 Golf 6. The main cause of these trouble generally 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 in a malfunction of the injector. If after checking, this noise originates from another part of the engine of your Volkswagen Golf 6, have a look at this article content for more infos.
The consequences of injector noise on Volkswagen Golf 6
Now that we have reviewed the different causes for injector noise on your Volkswagen Golf 6, we will end by stating the possible side effects of malfunctioning one or more of your injectors. Whether only one is blocked, or broken, or your entire fuel rail is involved, you cannot escape these consequences which can almost instantly 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 repercussions noticed by drivers is a serious loss of power. Indeed, 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 almost instantly affect your cylinders or pistons and your engine may tighten.
Here are three little suggestions 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>
