Common Symptoms of Audi Alternator Failure
The battery warning light comes on.
When the alternator fails to charge the battery, the battery warning light (usually a red battery icon) on the dashboard will come on. This is the most immediate sign of a fault 2.
Abnormal function of electrical equipment
Dimmed or flickering headlights, especially noticeable at low or idle speeds2.
Slow or malfunctioning equipment such as electric windows, heated seats, or audio systems.
Abnormal noise
Worn bearings or malfunctioning parts inside the generator may cause a roaring, whining, or metallic scraping sound, especially noticeable during acceleration 29.
Frequent battery loss or failure to start
A malfunctioning generator can cause the battery to recharge, and the vehicle may fail to start several times due to a lack of charge, requiring frequent power-ups29.
Burning odor or overheating
When the generator is short-circuited or overloaded internally, it may smell burnt rubber or wires, or even smoke in severe cases.
Unstable voltage
Use a multimeter to detect the battery voltage (normal should be 13.5-14.8V), if the voltage is lower than 12V or fluctuates sharply, indicating that the generator output is abnormal.
