Low Coolant light!!!!

[MEDSTUDENT87]

I recently changed my coolant hoses but not my coolant due to it being 6 months old and BMW coolant, which is expensive. Anyways now every time I start my car the low colant light comes on then will disappear and come one agian after the car is turned off and tells me to see owners manual. The thing is the coolant it at the perfect level and the system properly bled. I sprayed the plug at the bottom of the surge tank with parts cleaner to clean off some possible coolant that is still on there but it still comes on!!!!! What should I do to fix this. I like having the sensor but only if it works correctly and dosn't cry wolf having me check for coolant levels every time I go somewhere. It also does not happen consistently. HELP

How do you over ride the obd?

The coolant level sensor on my e34 is extremley picky. It often gives me BS readings. I've replaced it about three times and at this point have simply given up. The sensors for some reason just give false readings of coolant level. Nothing is a replacement for actually looking under the hood and checking your coolant level.

I haven't figured out how I could disable the sensor, or even if such a practice would be wise. My advice, check your coolant level, if it's fine, ignore the light and just keep an eye on your temperature gauge and coolant level under the hood.

Yea I always check all my fluids every time I fill up wiht gas just very annoying when you coolant is at ideal level and no leaks and it says you have low collant. When that light came on between fill ups I don't know if I might have sprung a leak. ya know? Well knock on wood it hasn't come on in a while I think coolant spilled on it when I changed all the hoses and it have disapated finaly. Tahnks for the info though.
