      Hi guys,
      I need some help finding the answer regarding my 2011 Mini Cooper S R56 engine codes.
      This are the following codes that somehow I believe are connected:
      2C3E – Quantity control valve activation – circuit open/ short to ground
      2D0C – Catalytic converter upstream oxygen sensor heating activation: circuit short to ground
      2D10 – Catalytic converter downstream oxygen sensor heating activation: circuit short to ground
      3400 – Engine oil pressure control valve, activation: circuit short to ground
      348F – Map thermostat activation: circuit short to ground
      37DE – Crankcase ventilation heating,activation: open circuit

        I would take the easiest error short to ground and start diagnosing that.
        You could also inspect for harness contact wear points.
        A wiring diagram of your specific vehicle will be very helpful.
