What Does Your Audi A4 Voltage Regulator Do?-
What Happens When It Fails
2
The job of a voltage regulator is to keep the
power output of an alternator stable- usually,
within the range of 13 to 14 volts.
3
By doing so, it achieves the following objectives

• Prevents battery from overcharging
• Protects the battery from voltage fluctuations

4
You can find it attached to the inside or outside
of your car alternator unit.
5
If it wears out, the battery will not get the
requisite amount of electric energy, as a result
of which it may die prematurely.

Lets discuss what else would happen if your Audi
A4s voltage regulator goes bad.
