It is rarely ever enjoyable to acknowledge an injector noise on your Audi Q7. It is a noise that happens continually, usually when you accelerate or your engine is idling. However, this indicator may be connected to multiple kind of trouble with your automobile injectors. It may not be anything severe, but when a continuing noise shows up, you have to be sure. Specifically since fixing your Audi Q7’s injectors can be costly. That’s why our team decided to create this article in order to support you see more clearly, learn about the different conceivable failures and distinguish your issue. To do this, we will first look at the normal running and usefulness of the injectors in your Audi Q7, then at the conceivable reasons from which an injector noise may come.
Attributes of the injectors
Injectors are a very useful element 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 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 causes of a clicking or knocking noise based on the injectors of your Audi Q7
Listening injector noises on your Audi Q7 may come from different origins, we will now focus on the potential causes of these. In most cases, the regular noise of a faulty injector is of the snap type. Here are the different sources of these noises and the solutions to be adopted to get rid of them. If you acknowledge another clicking noise but it is not from your injectors, we recommend you to browse this article about clicking noise on Audi Q7 to find the cause.
The explanations for injector clicking or knocking noise Audi Q7
A clicking or knocking noise from your injectors can be explained for different explanations. Indeed, the injectors of your Audi Q7 have three main tasks, to manage the vaporisation of the fuel, i.e., to convert the liquid into “gas” during injection, to facilitate its combustion. Then, its task is to manage the air/fuel dosage and at last the homogeneity of the mixture, always with the goal of improving combustion. If one of these three features 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 due to bad timing, or a bad quantity of mixture or finally an inhomogeneous mixture and will induce thoses knocking or clicking noises on your Audi Q7. The main cause of these concerns generally originates from a particle that gets into the injectors. The accuracy of the injector being in the nanometer range, any possible obstruction will inevitably end in a malfunction of the injector.

The effects of injector noise on Audi Q7
Now that we have reviewed the several reasons for injector noise on your Audi Q7, we will end by stating the possible side effects of malfunctioning one or more of your injectors. Whether only one is blocked, or broken, or your entire fuel rail is involved, you cannot escape these consequences which can quickly 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 common repercussions noticed by drivers is a severe loss of power. Indeed, if your engine is running on 3 out of 4 cylinders for example, you will undoubtedly have a loss of power
Finally, you risk deteriorating one of your pistons or your engine. Poor combustion will quickly affect 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>
