Does anybody know why my low coolant light comes on when I check its the level is good it seems like I have to change out the tank every year because of the float start to stick

 

Had this happen 6 months ago, replaced the tank. Are you using genuine Land Rover parts or aftermarket?

 

I had to do this in February 2019 - the expansion tank was replaced with one from Meyle at that time.

Today I replaced the Meyle one with a Nissens one for the same reason. So it lasted about five years and four months. 🤷‍♂️ Twsted the tank for continuity after removing it and it did behave differently than the brand new one.
