What color, do you have water in the oil as well?


White Smoke No Evidence Of Water in the Oil

Did the problem occur on the first start-up after the change or did it run OK .. then happen? Regressing to the "Water Damage" .. was the car immersed in water? OBC's are tough .. in fact it's one of the few things that may still work on a "Flood Damaged" car. BTW unless you are absolutely, positively sure the Computers have the same Algorithm you may consider putting your old processor chip in the new computer


Yeah, the "water damage" is the mysterious part here- sounds scary- if that car got flooded, it could be that almost anything else got ruined- white smoke is burning oil- did the engine get ruined?
