It is never pleasurable to acknowledge an injector noise on your Volkswagen Golf 3. It is a noise that appears frequently, usually when you accelerate or your engine is idling. However, this symptom may be connected to different kind of concerns with your vehicle injectors. It may not be anything serious, but when a continuing noise arises, you have to be sure. Specifically since fixing your Volkswagen Golf 3’s injectors can be costly. That’s why our team chose to produce this content page in order to help you see more clearly, learn about the different plausible failures and determine your issue. To do this, we will first look at the normal function and usefulness of the injectors in your Volkswagen Golf 3, then at the plausible triggers from which an injector noise may come.
Benefits of the injectors
Injectors are a very useful element of the operation of your engine unit. They were introduced to the modern vehicles about 20 years ago. Before their arrival, 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 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 vehicle (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 triggers of a clicking or knocking noise based on the injectors of your Volkswagen Golf 3
Hearing injector noises on your Volkswagen Golf 3 may result from different sources, we will now concentrate on the potential causes of these. In general, the regular noise of a faulty injector is of the snap type. Here are the several origins of these noises and the solutions to be put into practice to stop them. If you acknowledge another clicking noise but it is not from your injectors, we recommend you to read this content page about clicking noise on Volkswagen Golf 3 to discover the cause.
The causes for injector clicking or knocking noise Volkswagen Golf 3
A clicking or knocking noise from your injectors can be justified by different causes. In fact, the injectors of your Volkswagen Golf 3 have three main missions, to manage the vaporisation of the fuel, i.e., to convert the liquid into “gas” during injection, to ease its combustion. Then, its goal is to deal with 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 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 Volkswagen Golf 3. The main cause of these problems in most cases 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 effects of injector noise on Volkswagen Golf 3
Now that we have analyzed the several reasons for injector noise on your Volkswagen Golf 3, we will end by stating the possible side effects of malfunctioning one or more of your injectors. Whether only one is clogged, or damaged, or your entire fuel rail is involved, you cannot escape these effects which can fairly 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 basic consequences experienced 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 undoubtedly have a loss of power
Finally, you risk deteriorating one of your pistons or your engine. Poor combustion will fairly quickly affect your cylinders or pistons and your engine may tighten.
Here are three little tips 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>
