I have a 2004 sprinter with 250000 miles with the ecu light on. here's my story: the place I fuel everyday developed a problem with water in their fuel. They put treatment in my tank and cleaned out theirs, this was about 6 weeks ago. Today I decided to pump out my tank just to see if any water was in it. Fortunately it was free of water. I put the fuel back into the tank and started back to the terminal. 4 miles down the road the ecu light came on. I think it came on because I pumped the fuel out but I am not for sure. Anyone have any ideas or suggestions. I also wonder if the light will go off on its own or do I need to have it reset by a dealer. Outside of normal maintenance this is the first time I have had any hint of a problem with this van. The van starts and runs just like it always has.
Thanks
