It is never pleasurable to perceive an injector noise on your Volkswagen Amarok. It is a noise that appears continually, usually when you accelerate or your engine is idling. However, this indication may be linked to multiple types of trouble with your vehicle injectors. It may not be anything major, but when a recurrent noise arises, you have to be sure. Specifically since replacing your Volkswagen Amarok’s injectors can be expensive. That’s why our team decided to write this article in order to help you see more clearly, learn about the different plausible failures and determine your problem. To do this, we will first look at the normal functioning and usefulness of the injectors in your Volkswagen Amarok, then at the plausible causes from which an injector noise may come.
Benefits of the injectors
Injectors are a very useful part of the operation of your engine motor. They were launched to the modern cars 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 accurately (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 causes of a clicking or knocking noise caused by the injectors of your Volkswagen Amarok
Listening injector noises on your Volkswagen Amarok may result from different locations, we will now concentrate on the potential causes of these. In general, the typical noise of a faulty injector is of the snap type. Here are the several sources of these noises and the solutions to be implemented to stop them. If you perceive another clicking noise but it is not from your injectors, we recommend you to browse this article about clicking noise on Volkswagen Amarok to find the trigger.
The reasons for injector clicking or knocking noise Volkswagen Amarok
A clicking or knocking noise from your injectors can be explained for different reasons. In fact, the injectors of your Volkswagen Amarok have three main missions, to control the vaporisation of the fuel, i.e., to convert 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 aim of improving combustion. If one of these three features is altered, the main purpose of the injectors will be disrupted and this will lead to poor combustion. This bad combustion will be a violent explosion in the cylinders as a consequence of bad timing, or a bad quantity of mixture or finally an inhomogeneous mixture and will provoke thoses knocking or clicking noises on your Volkswagen Amarok. The main trigger of these situations generally originates from a particle that gets into the injectors. The precision of the injector being in the nanometer range, any possible blockage will inevitably result in a malfunction of the injector.

The end result of injector noise on Volkswagen Amarok
Now that we have reviewed the different causes for injector noise on your Volkswagen Amarok, 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 serious….
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 regular effects noticed 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 fairly quickly harm your cylinders or pistons and your engine may tighten.
Here are three little suggestions 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 swapping your diesel fuel filter regularly>
