It is never enjoyable to perceive an injector noise on your Audi A1. It is a noise that happens repeatedly, usually when you accelerate or your engine is idling. However, this indication may be linked to several types of trouble with your automobile injectors. It may not be anything major, but when a recurrent noise shows up, you have to be sure. Especially since fixing your Audi A1’s injectors can be expensive. That’s why our team decided to produce this article content in order to support you see more clearly, learn about the different possible failures and establish your problem. To do this, we will first look at the normal function and usefulness of the injectors in your Audi A1, then at the possible causes from which an injector noise may come.
Functions of the injectors
Injectors are a very vital part of the operation of your engine motor. 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 precisely (quantity of fuel injected, air/fuel mixture) via the analysis of the data collected 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 origins of a clicking or knocking noise coming from the injectors of your Audi A1
Finding out injector noises on your Audi A1 may result from different locations, we will now focus on the potential triggers of these. In most cases, the usual noise of a faulty injector is of the snap type. Here are the different sources of these noises and the solutions to be applied to prevent them. If you perceive another clicking noise but it is not from your injectors, we encourage you to browse this article content about clicking noise on Audi A1 to find the cause.
The causes for injector clicking or knocking noise Audi A1
A clicking or knocking noise from your injectors can be justified by different causes. In fact, the injectors of your Audi A1 have three main missions, to control the vaporisation of the fuel, i.e., to transform the liquid into “gas” during injection, to facilitate its combustion. Then, its task is to deal with the air/fuel dosage and at last the homogeneity of the mixture, always with the aim of improving combustion. If one of these three tasks 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 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 A1. The main cause of these trouble in most cases originates from a particle that gets into the injectors. The precision of the injector being in the nanometer range, any possible blockage will inevitably produce a malfunction of the injector. If after verifying, this noise originates from another part of the engine of your Audi A1, browse this article content for more infos.
The consequences of injector noise on Audi A1
Now that we have analyzed the diverse causes for injector noise on your Audi A1, 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 side effects which can promptly become major….
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 common effects experienced by drivers is a noticeable 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 degrading one of your pistons or your engine. Poor combustion will promptly damage your cylinders or pistons and your engine may tighten.
Here are three little suggestions 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>
