"DME Electrical Wastegate Valve Faults - Adaptation Limit Positions Not Detected. Engine runs with reduced power. Emissions warning lamp lights up. One or more of the following faults are entered in the DME fault memory. 123411 ""Electrical wastegate valve, limit position teach in: End stop (wastegate valve open) not found 123412 - Electrical wastegate valve, limit position teach in: End stop (wastegate valve open) not found Other consequential faults that also may be stored: 123401 - Electrical wastegate valve, adaptation: Cold start not learned 123437 - Electrical wastegate valve: Jammed closed Problems with electromagnetic compatibility (EMC). The PWM actuation (PWM = pulse-width-modulated) of the heat management module causes a fault condition on the 5V supply line of the electrical wastegate valve controller. This leads to a fault on the position sensor signal of the electrical wastegate valve controller."
