It is hardly ever pleasant to listen to an injector noise on your Seat Arona. It is a noise that comes up frequently, usually when you accelerate or your engine is idling. However, this indicator may be linked to several types of complications with your vehicle injectors. It may not be anything serious, but when a frequent noise happens, you have to be sure. Specifically since fixing your Seat Arona’s injectors can be expensive. That’s why our team chose to write this content in order to support you see more clearly, learn about the different plausible failures and establish your issue. To do this, we will first look at the normal function and usefulness of the injectors in your Seat Arona, then at the plausible triggers from which an injector noise may come.injector-noise-seat-arona

Attributes of the injectors

Injectors are a very significant part of the operation of your engine motor. They were launched to the modern cars 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 precisely (quantity of fuel injected, air/fuel mixture) via the analysis of the data received 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 triggers of a clicking or knocking noise coming from the injectors of your Seat Arona

Discovering injector noises on your Seat Arona may originate from different locations, we will now concentrate on the potential triggers of these. In most cases, 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 used to eliminate them. If you listen to another clicking noise but it is not from your injectors, we encourage you to examine this content about clicking noise on Seat Arona to find the reason.

The causes for injector clicking or knocking noise Seat Arona

A clicking or knocking noise from your injectors can be justified by different causes. Indeed, the injectors of your Seat Arona have three main tasks, to control the vaporisation of the fuel, i.e., to transform the liquid into “gas” during injection, to facilitate its combustion. Then, its mission is to manage 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 disturbed and this will lead to poor combustion. This bad combustion will be a violent explosion in the cylinders resulting from bad timing, or a bad quantity of mixture or finally an inhomogeneous mixture and will provoke thoses knocking or clicking noises on your Seat Arona. The main reason of these situations usually comes from a particle that gets into the injectors. The precision of the injector being in the nanometer range, any possible obstruction will inevitably end in a malfunction of the injector. If after checking, this noise comes from another part of the engine of your Seat Arona, read this content for more informations.

The repercussions of injector noise on Seat Arona

Now that we have reviewed the several reasons for injector noise on your Seat Arona, we will end by stating the possible consequences of malfunctioning one or more of your injectors. Whether only one is obstructed, or broken, or your entire fuel rail is involved, you cannot escape these effects which can fairly quickly become considerable….
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 common repercussions felt by drivers is a noticeable 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 fairly quickly affect your cylinders or pistons and your engine may tighten.
Here are three little recommendations to limit the risks linked 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>
