Exclamation Winshield Wiper Fluid Light

The windshield wiper fluid light is on , and even when i refill the reservoir with fluid, it still does not go off. What could be the issue ?

Are you sure the fluid is not leaking on the floor?
It could be a faulty sensor too.

The level sensor is bad. About $25-$30 from Autohauz or Pelican. Do a search of the forum for how to change it. You have to remove the headlight wiper and the headlight. Plan on about 1-3 hours with stops to refer back to the forum thread. Print it so you can refer to it outside. Look at the headlight rubber molding. If it needs to be replaced get it from some of the online MB dealers for about $50. Replace it while you are in there. If you wait long enough the radiator level sensor light will also come on. They are on the same circuit.

I am about to change mine for the second time. This time I will change the headlight moulding. If it bothers you, put electrical tape over the light until you change it.

Could it be that just the connection got loose and it just needs to be reattached ?

Coolant light was on a couple months ago, level fine, bought the sensor, no luck, figured out they are on the same circuit. Washer level sensor next. Is this in a sticky? Should be, replace both at same time.

2 97 600s with the same intricate issue in the same 3 month span. Parts life-cycle age as a constant, anyone? This is a good lesson for anyone who believes that mileage is more important than age in estimating pre-purchase potential repaiss - age is equally important, if not more so!

How many miles on yours, NY? Are you the one I sold my old wheels to?

I have about 75000 on my 1997 S600. I do not believe that i have bought any wheels from you. I have the AMG Aeros on my sedan.
On my car the coolant light is not on and functions properly; it's just the windshield wiper fluid light which is on.

It could be loose, but you still have to remove the headlight to get to it and check the connection. You are looking at 1-3 hours. You may as well change it while you are in there.

So I've got 184k, you've got 75k, and both ours failed within 3 months of each others. I was just making a general point about how age is every bit a factor as mileage, people pay up for low-mile cars but the reality is most of these components fail with age. 21 year lifespan! Wow. But yeah, case closed, replace both sensors because they're cheap and you're gonna be in there anyway.
