[long tall eta]

hey guys, my coolant level check panal light won't go out. level is ok. how do these sensors opporate? took it out and cleaned it up as best i could but still the check light comes on. really dont wana spend the 28 bucks plus shipping for a new 1 if there is an easier fix.

the coolant level sensor itself is bad. it's what the wires connect to on your coolant reservoir. they always go bad. i believe the part is $10 from bmw.

I used a fine sand paper to clean mine and it worked.
