The air pump belt is a common emission component found in many cars especially the older ones equipped with V8 engines.
The air pumps purpose is to reduce emissions and is usually driven by an engine accessory belt.
Moreover, the air pump belt in your Audi is made up of rubber which will wear out and will ultimately need to be replaced.
Here are certain signs associated with the malfunctioning of the air pump belt in your Audi.
Appearance of cracks on the belt is the first visual sign that the air pump belt needs to be replaced.
In due course of time due to the constant exposure to extreme heat from the engine, cracks will develop on and at the ribs of the belt.
Cracks are permanent damage to the belt that weakens its structural stability which makes the belt more susceptible to failure.
You must inspect the air pump belt from time-totime for cracks, large chunks missing or scuffs along the outside.
As the air pump belt begins to wear it will also give rise to other problems in your car.
One of the most common problem is that it will weaken your belt to a point where entire chunks of rubber can break off.
Any places along the ribs of the belt where the rubber has broken off are considered weakened and the places along the belt where it is more likely to occur.
Whenever the air pump belt malfunctions, then it has a direct effect on the AC of your Audi.
Another prominent sign of excessively worn out air pump belt is scuffing along the edges or outsides of the belt.
Mostly it is caused due to the misalignment of the belt on the pulley or by contact with some sort of debris or component of the engine.
In addition to this, some scuffs may cause threads from the belt to come loose.
Loose threads along the edges or outside surface of the belt are obvious signs that the belt should be replaced in your Audi.
