radiator light

[Dinan325I]

Hi brother Bimmer drivers I am new to this so I am not sure if this topic was discussed. When I start my e46 325i my radiator light comes on. After driving a bit it goes off. I had it checked and the dealer couldn't find anything wrong. Now the light comes on and off more frequently. Can anyone help me with this, I don't want to ruin my bimmer. Thanks in advance!!!!![bmwdance]

Just had this exact issue last week -- the dealer topped off the antifreeze, and the light went out.

In the manual, it says this light goes on when the fluid is low, are you sure your fluid is not low?

Deal checked the hoses the belts and level of coolant is normal. I even had the water pump replaced. So I am at my witts end. Could it be a defective switch?

Could be a defective switch. The float/contact mechanism cna get gunked up. This is common enough that the dealer should have checked it.

Want to thank everyone for there input. What I did was flush the radiator myself and cleaned out the floating devise. Seems to work.
