It is never pleasurable to hear a noise from your car you don’t know where from. Thus what if you discover a serpentine belt noise that persists on your Audi Tt? It is extremely plausible that this is a minor problem, but before being sure, it is better to operate some investigations. If this belt noise comes from your serpentine or driving belt, our team has written a post to support you finding and solving it. First, we will look at the serpentine belt noises on your Audi Tt and then we will check out the sources of these sounds.
I encounter noises from serpentine belt Audi Tt
The best technique to check the state of your belts is to listen to your car. As soon as you find sounds such as squealing or bells, you should take a closer look to examine their origin. The role of the serpentine belt or driving belt of your Audi Tt is to transmit the movement of the engine to the secondary parts that it will supply with energy. Like steering, air conditioning, water pump. Its role is therefore important in the normal functionality of your car. The serpentine belt is said to be asynchronous, i.e. unlike the timing belt, it has the capacity to drive different engine parts at variable speeds.
I hear squealing noises on my serpentine belt Audi Tt
This type of squealing belt noises on Audi Tt, which will often be acute, can commonly arise when the engine is cold, or when the acceleration increases in intensity. . This type of sound must be significant and it is often quite simple to connect it with one of these belts. To examine, do not hesitate to open your bonnet, engine running cold and check the origin of this noise, the serpentine or driving belt being accessible, it should not be too difficult for you to locate a belt noise on your Audi Tt. The reason of this problem can be connected to the damper pulley, which operates as a damper to get rid of irregularities in the tension in the motor cycle and therefore in the energy transmission to the belt. This results in a loose belt that will jerk. However, you still have an opportunity that this phenomenon is annodine. As the serpentine belt of your Audi Tt is exposed, it may squeak due to excessive humidity due to weather conditions and it may stop with a change in conditions. Remember to examine the state of your belt (crack, crack), if this is the case change it, otherwise simply tighten the belt.
I hear loud serpentine or driving belt noises Audi Tt
Just like squealing, a driving belt noise on your Audi Tt that sounds like a loud grinding sound can express a lot about its state. It is therefore important that you look further and locate the cause for this sound that can signal the end of your belt’s life. Like squealing noise, it can be identified in most cases when cold . It generally means a worn pulley whose streaks no longer allow it to be driven properly. Other possibilities, the dynamic belt tensioner or the disengageable pulley of the alternator may be at the origin of this problem. Make sure you examine first the serpentine/driving belt which in most cases is the reason of this problem, otherwise it will be necessary to change the tensioner or pulley.
I hear bearing noises on the serpentine belt of my Audi Tt
Finally, if in your case you recognize a bearing belt noise on Audi Tt, it is plausible that it is connected to a serpentine belt that is too tight . Indeed, it is plausible that its size may be smaller than recommended and cause the entire system to overvoltage, resulting in this whistling noise or slight rolling noise. The problem in this case is that the bearing bearings or the Damper pulley may fail . Remember, therefore, to stretch the belt to limit the risks or to change it if it is too short. If after checking all thoses possibilities, you still detect a belt noises, read our article about timing belt noises on Audi Tt which could maybe help you.
