ok rebuilt buddies m7 carb that he decided to meltdown, got her back together and everything is good except light is constantly flashing code states water temp to high but can't be at start up anyways changed out the sensor on the bottom of the case and still there. Do you need to flash the ccu kinda like a car to erase codes on these or am I missing something else. Thanks

the only time i have see this is in an over heat condition, check the waterpump for flow and no air in the system.

check the connector for bent pins on the temp sensor. and a long shot pull the valves and make sure thay are clean.

ya I had that once that will put your M7 in "limp" mode and only let you reach 6100rpms or so. Check to see if they are connected, if they are and its still flashing, tie the valves open

Had same issue after my last rebuild. Ended up being kinked servo cables from rerouting. I also went and took all my connections apart and put dielectric grease in them and my issues all went away.
