It is hardly ever relaxing to notice an injector noise on your skoda fabia. It is a noise that appears repeatedly, usually when you accelerate or your engine is idling. However, this indication may be related to multiple types of complications with your car injectors. It may not be anything major, but when a continuing noise shows up, you have to be sure. Especially since repairing your skoda fabia’s injectors can be expensive. That’s why our team chose to produce this article content in order to help you see more clearly, learn about the different possible failures and establish your trouble. To do this, we will first look at the normal running and usefulness of the injectors in your skoda fabia, then at the possible causes from which an injector noise may come.
Attributes of the injectors
Injectors are a very significant component of the operation of your engine unit. They were released to the modern automobiles 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 precisely (quantity of fuel injected, air/fuel mixture) via the analysis of the data received from the various sensors equipping the car (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 reasons of a clicking or knocking noise caused by the injectors of your skoda fabia
Discovering injector noises on your skoda fabia may originate from different locations, we will now focus on the potential causes of these. In most cases, the typical 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 eliminate them. If you notice another clicking noise but it is not from your injectors, we encourage you to read this article content about clicking noise on skoda fabia to locate the cause.
The reasons for injector clicking or knocking noise skoda fabia
A clicking or knocking noise from your injectors can be explained for different reasons. Indeed, the injectors of your skoda fabia have three main tasks, 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 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 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 because of bad timing, or a bad quantity of mixture or finally an inhomogeneous mixture and will trigger thoses knocking or clicking noises on your skoda fabia. The main cause 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 result in a malfunction of the injector.

The consequences of injector noise on skoda fabia
Now that we have analyzed the diverse reasons for injector noise on your skoda fabia, we will end by stating the possible side effects of malfunctioning one or more of your injectors. Whether only one is clogged, or broken, or your entire fuel rail is involved, you cannot escape these side 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 felt by drivers is a severe 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 degrading 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 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>
