'09 Carrera S
A couple of weeks ago my car alerted me that the washer fluid level was low. I added a small amount of washer fluid (all that I had at the time). A few days later, the warning appeared again, so I added about a half gallon of washer fluid.

Last night, the warning popped up again. As far as I know, the fluid is not leaking out of the tank, as I don't see any wet spots on my garage floor. However, this is the rainy time of the year here in NW Washington, so driving the car on wet roads tracks water into the garage. I haven't yet pulled the fender liner off to get at the tank.

Does this symptom of repeated warnings of low washer fluid level suggest that the washer tank sensor is going bad? Or could it be something as simple as just cleaning the electrical contacts?
