    Charge pressure control actuator

    Hi all,

    Golf 2014 1.4 TSI (122) received EPC and went into limp mode, restarted car and the light EPC error went away. EPC came back, so did the above again, but then engine management light appeared. Plugged into system and received P334B/013131 - Charge Pressure Control Actuator: Mechanical Malfunction. Car has only covered 23000 miles, is driving fine at the minute and actuator is not getting stuck when starting car. Have seen that this is a common issue on the 1.2 TFSIs were the ECU needs updated to sort out the actuator. Have not heard of this affecting ‘many’ 1.4 122 versions, keen to hear from you guys.

    Hi,

    Please post an Auto-Scan for context.

    The engineering problems are likely insurmountable. It would be like proposing to land a rocket booster section on a barge floating in the middle of the ocean.

    Hi,

    Will post when I get the chance. Can you just answer a question? On the following link it makes reference to 1.2 ECU updates, would this also apply for 1.4 engines? http://wiki.ross-tech.com/wiki/index.php/P334B/013131
