I have a 2018 Q50 RS400 and I've been getting the "windshield wiper fluid low" dash light. So I've made sure it was full and I've reset the system by unhooking the negative on the battery and after a few minutes of driving that sum beaatch comes back. Anyone else ever have this problem and know of a solution? It's not the end of the world to get that warning but it's a pain in the butt cuz it takes over the mph view at any moment when it does it and I have to click to get back to it. That's why I hate it, tho it is a first world problem, any help will be much appreciated.

If the washer fluid level is low, you won't get a low washer level warning for 3 minutes after turning on the ignition. Since you've filled the reservoir and you're still getting a low-level alert, I'd say your level switch is faulty. It's located on the bottom of the reservoir, but you'll have to remove the driver's side front fender protector to access the switch.

It's a float-type switch so I'd check to make sure the float is freely moving as it has a small magnet in the float that pulls in a reed switch when the level gets low. If it is moving properly, then you might check the continuity of the switch by connecting a multimeter to the switch and tilting the switch back and forth to engage the magnet on the reed switch.

I thought when we discussed this a few years back it was determined that the type of washer fluid affected the level sensor? Or has it since been determined that the level sensor is a float in all model years and the type of fluid was a red herring?

I thought we came to the conclusion that there was only a float-type level sensor in that thread. If so, then fluid conductivity isn't relevant. If there is also a conductivity type level sensor available, then it could be possible that certain washer fluids may not have sufficient conductivity to work with the sensor. I don't think that's the case though.

the funny thing is, all that is in there is straight water. It was low and I filled it with just plain kentwood water and then now all this crap.

Oh yeah, I just joined the ranks of the SprintBooster clan. Well I ordered it, so I haven't fought the install yet, but I got it based off of all you knuckleheads reviews. I trust yall tho, so I know I'm good and it'll be good

If you have the proper tools, a physique like a spider monkey, and grip strength strong enough to tear a phone book in half, you'll have no trouble. If not, may God be merciful.

Dang Avedis I've been all over this forum and you've got your fingerprints on just about every discussion. How do you get all those in depth diagrams of our cars and the different areas of them?

I should wash my hands more often.
