We get this message on our 210G, 160G and 250G. It always seems to happen on a cold start first thing in the morning. Clearing the code seems to solve the problem for the day, but the issue usually comes back. I have read a few others posts stating that there could be some hose clamps that need to be tightened. Other than that is there anything else to check. Perhaps a bad sensor or a pump issue? RED ECU 000111.01
Welcome to HEF Dan . If I remember ,the coolant surge tank has 2 level sensors in it. One positioned at a low coolant level and one position indicating the tank is empty. Before start up , check around for cold leaks at the clamps on rad hoses , heater hoses etc.
Your memory is really good!
I'll give that a try. Thanks!
Please see attached file for more details. Good luck.
