Bad Voltage Regulator (C180 2013)
Hello, what are the signs of a bad regulator? The part is expensive and none of the mechanics can say for sure that the symptoms of my car are due to bad voltage regulator. Car is C180 2013.
Symptoms:
Once car starts and i am driving the first 5 minutes ( especially when going from 1st gear to 2nd) all car electronics turn off then on, such as door locks, screen, inside and outside lights flickering, steering wheel hardens.. and i get warning lights regarding ESP and both airbags are unavailable check user manual.
The scanner says there is an overvoltage along with other issues such as ESP and door buttons errors but the mechanic says its due to the overvoltage.
Any idea?
