It is never pleasurable to listen an injector noise on your Audi R8. It is a noise that happens continually, usually when you accelerate or your engine is idling. However, this indicator may be connected to different sort of complications with your automobile injectors. It may not be anything severe, but when a repeated noise arises, you have to be sure. Most importantly since fixing your Audi R8’s injectors can be costly. That’s why our team decided to write this content in order to help you see more clearly, learn about the different conceivable failures and establish your problem. To do this, we will first look at the normal function and usefulness of the injectors in your Audi R8, then at the conceivable triggers from which an injector noise may come.
Attributes of the injectors
Injectors are a very vital part of the operation of your engine unit. They were launched to the modern automobiles about 20 years ago. Before their appearance, 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 ability, 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 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 get the best possible combustion in the cylinders.
The different origins of a clicking or knocking noise coming from the injectors of your Audi R8
Discovering injector noises on your Audi R8 may come from different sources, we will now center on the potential causes of these. In most cases, the common noise of a faulty injector is of the snap type. Here are the different origins of these noises and the solutions to be applied to stop them. If you listen another clicking noise but it is not from your injectors, we advise you to go through this content about clicking noise on Audi R8 to find the trigger.
The reasons for injector clicking or knocking noise Audi R8
A clicking or knocking noise from your injectors can be justified by different reasons. Indeed, the injectors of your Audi R8 have three main missions, 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 at last the homogeneity of the mixture, always with the objective of improving combustion. If one of these three functions 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 due to bad timing, or a bad quantity of mixture or finally an inhomogeneous mixture and will provoke thoses knocking or clicking noises on your Audi R8. The main trigger of these trouble usually originates from a particle that gets into the injectors. The precision of the injector being in the nanometer range, any possible obstruction will inevitably end up in a malfunction of the injector.

The repercussions of injector noise on Audi R8
Now that we have reviewed the several reasons for injector noise on your Audi R8, we will end by stating the possible side 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 severe….
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 known effects felt by drivers is a distinctive 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 promptly affect 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>
