It is hardly ever pleasurable to perceive an injector noise on your Volkswagen Fox. It is a noise that appears repeatedly, usually when you accelerate or your engine is idling. However, this sign may be connected to several kind of complications with your vehicle injectors. It may not be anything major, but when a repeated noise comes out, you have to be sure. Especially since fixing your Volkswagen Fox’s injectors can be expensive. That’s why our team chose to write this article in order to support you see more clearly, learn about the different conceivable failures and establish your issue. To do this, we will first look at the normal running and usefulness of the injectors in your Volkswagen Fox, then at the conceivable reasons from which an injector noise may come.
Benefits of the injectors
Injectors are a very vital element of the operation of your engine. They were launched to the modern vehicles about 20 years ago. Before their introduction, 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 opportunity, 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 vehicle (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 get the best possible combustion in the cylinders.
The different causes of a clicking or knocking noise caused by the injectors of your Volkswagen Fox
Discovering injector noises on your Volkswagen Fox may come from different sources, we will now center on the potential triggers of these. Generally, the common noise of a faulty injector is of the snap type. Here are the several origins of these noises and the solutions to be applied to get rid of them. If you perceive another clicking noise but it is not from your injectors, we encourage you to browse this article about clicking noise on Volkswagen Fox to discover the reason.
The causes for injector clicking or knocking noise Volkswagen Fox
A clicking or knocking noise from your injectors can be justified by different causes. In fact, the injectors of your Volkswagen Fox have three main tasks, to control the vaporisation of the fuel, i.e., to convert the liquid into “gas” during injection, to ease its combustion. Then, its mission is to manage 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 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 trigger thoses knocking or clicking noises on your Volkswagen Fox. The main reason of these problems in most cases comes 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.

The consequences of injector noise on Volkswagen Fox
Now that we have examined the diverse reasons for injector noise on your Volkswagen Fox, we will end by stating the possible consequences of malfunctioning one or more of your injectors. Whether only one is obstructed, or damaged, or your entire fuel rail is involved, you cannot escape these repercussions which can fairly 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 known consequences experienced by drivers is a severe 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 deteriorating one of your pistons or your engine. Poor combustion will fairly quickly 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>
