    Hey guys, I really need some help diagnosing on my 07 ms3. Finished the swap yesterday and the car was perfectly fine. Now today it won’t hardly run for sh*t and is now throwing these 5 codes:
    PCM
    -P0117
    -P0245
    IC
    -U2064
    -U2023
    ABS
    -U2023
    Yes, I’ve tried clearing codes. Yes, I’ve reset the battery. Yes I’ve checked connections. Just overall stumped at this moment. Any help would be greatly appreciated.

    The coolant temp sensor and wastegate solenoid both terminate in connector 2 of the PCM, as do the CAN bus wires.

    Check the connector for corrosion or damaged pins.

    Finished what swap? Turbo? Engine? IM? Intake?
    Failing the reply above me go check all your harness connections and make sure all the grounds are properly attached.
