It is rarely ever enjoyable to perceive an injector noise on your Audi Q2. It is a noise that happens repeatedly, usually when you accelerate or your engine is idling. However, this symptom may be connected to multiple kind of complications with your automobile injectors. It may not be anything major, but when a persistent noise appears, you have to be sure. Most importantly since replacing your Audi Q2’s injectors can be costly. That’s why our team chose to create this article content in order to help you see more clearly, learn about the different possible failures and determine your trouble. To do this, we will first look at the normal running and usefulness of the injectors in your Audi Q2, then at the possible triggers from which an injector noise may come.
Benefits of the injectors
Injectors are a very fundamental part of the operation of your engine. They were launched to the modern automobiles about 20 years ago. Before their arrival, 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 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 obtained from the various sensors equipping the automobile (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 obtain the best possible combustion in the cylinders.
The different causes of a clicking or knocking noise based on the injectors of your Audi Q2
Experiencing injector noises on your Audi Q2 may come from different origins, we will now focus on the potential causes of these. In general, the usual noise of a faulty injector is of the snap type. Here are the different origins of these noises and the solutions to be put into practice to stop them. If you perceive another clicking noise but it is not from your injectors, we advise you to read this article content about clicking noise on Audi Q2 to locate the reason.
The causes for injector clicking or knocking noise Audi Q2
A clicking or knocking noise from your injectors can be explained for different causes. Indeed, the injectors of your Audi Q2 have three main tasks, to control the vaporisation of the fuel, i.e., to transform the liquid into “gas” during injection, to ease its combustion. Then, its mission is to deal with the air/fuel dosage and finally the homogeneity of the mixture, always with the goal of improving combustion. If one of these three functions is altered, the main role of the injectors will be disrupted 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 provoke thoses knocking or clicking noises on your Audi Q2. The main reason of these trouble generally 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 up in a malfunction of the injector.

The side effects of injector noise on Audi Q2
Now that we have reviewed the different causes for injector noise on your Audi Q2, we will end by stating the possible effects of malfunctioning one or more of your injectors. Whether only one is blocked, or damaged, or your entire fuel rail is involved, you cannot escape these repercussions which can almost instantly become considerable….
First, you risk destroying your exhaust unit 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 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 degrading one of your pistons or your engine. Poor combustion will almost instantly harm your cylinders or pistons and your engine may tighten.
Here are three little recommendations 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 changing your diesel fuel filter regularly>
