I did PM Shogun about this already, but check this out:

--------------------------------------------------------------------------------



My float on my sensor broke off, and got the Coolant Level message. I ordered one from BMA and put it in. I still get the message/error. I took it out again and moved it up and down while connected to the car harness. It seemed to be happy only when the float was down (this is the closed contact). When you hold it up, like the coolant was full, it opens the contact and you get the message/error. It seemed that the sensor was made opposite or wrong.

I verified this by checking out my old sensor. With the float moved toward the connector pins, open continuity. When floating up or away from the connector pins, closed continuity/contact.

I called BMA and they sent a replacement. It is the same as the first. The float moving up causes the contact to open and that makes the car think you have low coolant. Can you shed any light on this?

Thanks in advance,
