01 ML 320 Washer Fluid Sensor
 

Our ML ran out of washer fluid the other day and the dash sensor did not come on. Odd that it came on several weeks ago. I would not be concerned except all of this is on the same can bus and may be a sign of other things.

Am I barking up a tree or should I just ignore it for now. Any resistance tests I can do on the sensor?

thanks!

On the early ML's the level sensor is available ONLY by buying the complete reservoir.

didn't the sensors appear later? i don't recall seeing a sensor on earlier models.
