You certainly suspect it, however the alternator is a determining element in an engine. This is the one who is responsible for transforming energy of the engine block of this Audi in Electricity supply in order to recharge the battery. In the specific case where there is a problem, this could especially cause electrical failures. It is thus important to pay attention to it. Only the problem could also come from your belt, and even pulleys. We will discover through this post where the problems related to noise that comes out.
Noise alternator belt on an Audi
La alternator belt, also called an accessory belt, is the capital component which contributes to the good action of the alternator. It is this one which, through its convolution, drives the alternator and will produce electricity. However, it also serves to operate different pumps of the engine block. If it breaks, the latter may cause damages really important in the engine of this Audi.
A metallic noise on the Audi:
Here is a hazard that usually comes Cold. The most common reason is that some of the streaks on this belt will be damaged. However it could also happen when the pulley is a little out of gon. If the belt breaks up, it can obviously break. If it happens that you recognize this noise, the best thing to do is to replace the belt and the problem will be solved almost every time.
A sharp screech on the Audi:
This remains the most recurrent concern, but also the least critical. It usually comes out cold, but will sometimes come back even hot sometimes. However, it suddenly stops. This inconvenience generally comes as soon as the accessory belt is relaxed. Just the tighten and voila. Small warning, when it remains in this situation for a long time, the belt may be damaged and lead to a more serious incident in the long term. This acute screeching also sometimes occurs when the damper pulley is damaged, however it is less frequent.
A slight hiss or breath on the Audi:
It is the opposite of the preoccupation of before. The belt is certainly excessively tight or too short. You can imagine what you have to do!
Alternator noise on an Audi
In the case where it is really the alternator which makes noise and not the belt, then the problems will be fundamentally different. However, the noise you hear may have similarities to that of a belt, either high hiss. The dysfunction will sometimes come from a electrical failure, this is relatively common. If ever voltage essential to the good activity of the Audi is usually deficient, this is generally seen during a lack of alertness of lights or bulbs in your automobile. If the lack of alertness is excessive, it is possible that the battery indicator stay on. In order to achieve a good diagnostic malfunction, it is useful to use a voltmeter to check the tension on the + and the least of its battery, with the ignition on of course. If the voltage is lower than that recommended on the battery, the problem will come from the alternator. In this case, it usually needs to be replaced.
Conclusion:
A new alternator noise usually comes from the alternator belt, but will sometimes also come from the alternator itself. Economically, an alternator belt costs considerably less compared to the alternator. Get a quote from a auto repairer rather than starting work, because you can never be sure of the source of the problem. Hope this article has helped you, if so you can write a comment. Enjoy the road with your Audi.
