It is never pleasurable to listen to an injector noise on your Volkswagen New Beetle. It is a noise that comes up repeatedly, usually when you accelerate or your engine is idling. However, this warning sign may be related to multiple sort of concerns with your automobile injectors. It may not be anything major, but when a recurrent noise happens, you have to be sure. Especially since repairing your Volkswagen New Beetle’s injectors can be expensive. That’s why our team decided to prepare this content in order to help you see more clearly, learn about the different conceivable failures and establish your issue. To do this, we will first look at the normal functioning and usefulness of the injectors in your Volkswagen New Beetle, then at the conceivable causes from which an injector noise may come.injector-noise-volkswagen-new-beetle

Attributes of the injectors

Injectors are a very fundamental element of the operation of your engine motor. They were launched to the modern automobiles about 20 years ago. Before their appearance, 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 collected from the various sensors equipping the automobile (engine temperature, acceleration level, engine speed, etc.). Their goal 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 New Beetle

Hearing injector noises on your Volkswagen New Beetle may result from different locations, we will now look into the potential triggers of these. In general, 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 implemented to prevent them. If you listen to another clicking noise but it is not from your injectors, we suggest you to examine this content about clicking noise on Volkswagen New Beetle to locate the trigger.

The reasons for injector clicking or knocking noise Volkswagen New Beetle

A clicking or knocking noise from your injectors can be justified by different reasons. In fact, the injectors of your Volkswagen New Beetle have three main tasks, to control the vaporisation of the fuel, i.e., to convert the liquid into “gas” during injection, to ease its combustion. Then, its task is to manage 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 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 Volkswagen New Beetle. The main trigger 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 end result of injector noise on Volkswagen New Beetle

Now that we have examined the different causes for injector noise on your Volkswagen New Beetle, we will end by stating the possible end result 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 quickly become serious….
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 felt by drivers is a significant loss of power. In fact, 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 quickly damage your cylinders or pistons and your engine may tighten.
Here are three little suggestions to limit the risks connected with 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>
