Audi A6 power control module failure reasons: low output voltage, high input voltage. The following details the causes: Low output voltage: If the circuit input voltage is too low, it can cause the circuit to malfunction. For example, in microcontroller systems, a sudden increase in load can lower the microcontroller's power supply voltage, causing a reset. If the power supply operates at a low input voltage for a long time, the lifespan of the circuit can also be significantly affected. High input voltage: If the input voltage is too high, it can easily burn out the circuit, causing significant damage. Solution: Replace with an input voltage within a reasonable range. If there is interference voltage, consider adding a TVS diode or voltage regulator at the input.
