Good morning we have a GOLF SERIES 5 TARGETED DG711TW ENGINE BKD 16 VALVES 103 KW CHASSIS WVWZZZ1KZ7P027553 DIESEL THAT SPORADICALLY GETS ERROR P3101 BODY BUTTERFLY . NOT IMMEDIATELY AFTER CATCHING THE ERROR DOES THE MIL LIGHT COME ON. WHEN WE HAVE THE ERROR THE CAR RUNS WELL AND PERFORMS WELL BUT IT SWITCHES OFF BADLY. ON PIN 1 AND 4 OF THE PLUG WE HAVE CURRENT AND VOLTAGE, THE PLUG WE HAVE REPLACED IN ACTIVATION THE BODY WORKS AND IT OPENS ALL AND CLOSES ALL WITH THE PANEL ON AND OFF. THE BODY IS NEW. we would like to know, in addition to your advice if the body is controlled directly from the engine control unit. THANK YOU
