    ECU potential bad

    Lately we've had a lot of rain, I went to drive and the car quickly went into limp mode. I have about 20 different codes now, main code of P0651. I found water sitting on top of the ecu housing. Think this could be the cause? I don't know why the date for the fault codes are from random years and not the current date.

    Code:

    I guess the first thing I would do is to pull the connector(s) from ECU and check the condition of the pins. There should be no water in there, and no corrosion.

    Get one of these if it doesn't have one on ECU already and that goes for any MED series ECU, without this you are just asking for ingress bad time trouble?
