VW Code 03673
03673 Description And Summary : |
|---|
Diameter in engine actuator supply voltage 'c', circuit high causes include a bad boost pressure sensor or a vacuum leak in the system turbo/super charger wastegate solenoid d (n389), signal high . So for next bank 2, system too rich off idle is the final reason of the code. |
