Check coolant level

Hi, I have a 1994 BMW 325i and it shows "check coolant level" but when I check my coolant, it has enough coolant/antifreeze fluid in it. So would it be the sensor failure for the coolant ?

The expansion tank is split down the middle, I had mine look full and got the same issue. The other side is hard to see from the cap. You can try filling it to the split line, or through the bleeder screw hole. Otherwise it could be your sensor, though I'm not sure how common a failure is with those.

It's much more likely to be a bad sensor.

Check coolant level

I have a 325i 1994 convertible and had the same problem. Finally I took a small screwdriver (like for eyeglasses) and wrapped a small amount of sandpaper around it. I used it to clean the female portion of the expansion tank sensor connector. Under the hood by the passenger headlight. I pushed it back together and I've never had the light come on again.

I have two e36 both of them throw the same light every time I get in the car an when I start them the light goes off. Both tank are full also. I'm pretty sure the sensor in the bottom of tank are notorious for this issue. An the oem expansion tank is **** lol
