Hey there i have experienced the same issue. car was stalling out. opened my ECU box and found there to be water in there which was causing my car to stall and throw random check lights at me. e91 330i wagon. Just wondering what the best thing would be to do, ive taken the ECU out and trying to dry it as best as i could but how much would a second hand ECU to replace and re flash be etc?
Does my ecu look salvageable or do I need a new one? Any info would be great thanks
cheers
