The voltage regulator's function is to control the field current applied to the spinning rotor inside the alternator. A bad voltage regulator in your Audi A4 leads to a poor supply of voltage to different parts. It will also lead to a non-functioning instrument cluster. See the given slideshow for the 5 most common symptoms of a bad voltage regulator in Audi A4.

1. 5 MOST COMMON SYMPTOMS
OF BAD VOLTAGE REGULATOR
IN AUDI A4
TOLD BY MECHANICS OF
SANTA BARBARA

2. A voltage regulator
maintains an even flow of
electrical power to the
various electrical systems.

3. Generally, the voltage
regulator can be found
mounted inside or outside of
the alternator housing.

4. And if you own an Audi A4
in Santa Barbara, then
you need to take more care
of the flow of current.

5. The voltage regulator's
function is to control
the field current applied
to the spinning rotor
inside the alternator.

6. 5 SYMPTOMS OF A BAD
VOLTAGE REGULATOR

7. DROP IN INTERMITTENT
VOLTAGE

8. A bad voltage regulator
in your Audi A4 leads to
a poor supply of voltage
to different parts.

9. You will start to
experience the engine
sputtering and a lack of
acceleration.

10. You have to deal with a
rough idle as the power
is not being regulated
correctly.

11. HIGH VOLTAGE OUTPUT

12. When the voltage
regulator is broken, the
maximum output is 15
volts or higher.

13. The higher voltage
output will trigger
harm to
the different
electrical modules.

14. The first sign of this issue
is dimming
headlight or taillight.

15. ILLUMINATED ENGINE OR
BATTERY WARNING LIGHT

16. To find the real cause, check the
diagnostic
trouble codes and use a multimeter
to run a quick voltage check.

17. The best way is to take
your vehicle to the
local Audi shop and get
a detailed inspection
done on your Audi A4.

18. It will help to find the
issue and fix it before
causing more damage to
the other parts of your
car.

19. INSTRUMENT CLUSTER
NOT
FUNCTIONING

20. The instrument cluster
offers critical
information during
driving like speed,
fuel level and many
more.

21. The instrument cluster
requires a minimum
amount
of power to keep
functioning and show
all the details you
need when driving.

22. A bad voltage regulator
will lead to a
non-functioning
instrument cluster.

23. FLICKERING
HEADLIGHTS

24. The headlights are the
one which is most
affected by a faulty
voltage regulator in your
Audi A4.

25. The high-beam bulbs
won't light up properly
indicate an issue with
the electrical supply.

26. The voltage isn't being
well regulated and has
an impact on the inner
lamps and other devices.

27. CONCLUSION

28. You must never drive with a bad voltage
regulator as it might cause severe
problems in your Audi A4.

29. Whenever you find any of the above
symptoms, it
is recommended to get the car inspected
by an experienced mechanic in Santa
Barbara.
