s4 t2, like the tiel says, I've got coolant and oil. I did a search and found a few posts about arguments of disabling the buzzer or keeping it.

The water level sensor that alarms the buzzer is the one on the thermostat neck? I actually have a new one on there. My old one separated. Or is the sensor on the radiator? I did a Koyo n Flow a half a year ago and threw away the original, but I swear there were no sensors on there before I threw it away.

My oil level sensor is hooked up and the connection is good.

I really don't want to disable the buzzer, I guess I will have to study the wiring to troubleshoot. Any advice, comments?

 

the rad sensor is the one that makes the buzzer go off.(top of rad)
the single brown wire near the AFM is the one to look at.That goes to the Coolant level sensor at the top of the rad.If that is broke or disconnected you get the buzzer going off.
you can ground that wire from the harness to GROUND and it should stop the buzzing.
Note: you really should have this working though as it lets you know the coolant level.

 

Ahhh, thanks! I'll have to buy another sensor, doh!

 

you dont have to buy another sensor.. all it is is a piece of metal that conducts through your coolant to ground the buzzer circuit. it may just need cleaning, or check the wire for continuity

 

I threw mine away with my old radiator

 

Can ground the wire. On my s5 it is brown/yellow. Just so you can drive it until you fix the problem
