P0658 AUDI – Actuator Supply Voltage ‘A’ Circuit Low

P0658 AUDI Possible Symptoms

Engine Light ON (or Service Engine Soon Warning Light)

P0658 AUDI Possible Causes

Faulty Transmission Solenoids,Transmission Solenoids harness is open or shorted,Transmission Solenoids circuit poor electrical connection,Faulty Powertrain Control Module (PCM)

P0658 AUDI Description

The Powertrain Control Module (PCM) monitors the transmission solenoid circuits by supplying voltage to the solenoids through this circuit, then checking for voltage returning from the solenoids through each of the individual solenoid control wires. If one of the solenoid return circuits does not have the correct voltage returning to the PCM, the PCM will set a code for that solenoid.
