Fluid leaking
I have a 2016 E400, don’t drive it much, in fact it’s probably been a month since I’ve driven it. It stays parked in my garage. I woke up this morning and there is a huge puddle of clear water all around the front of the car that wasn’t there yesterday. I’ve determined that it’s windshield washer fluid. I’m just trying to figure out how all the sudden all my windshield washer fluid decided to leak out? It’s the strangest thing. Like I said, it hasn’t been driven in a month. Any ideas as to why it’s started leaking?

It's the standard washer pump seal that falls apart.
It's an easy 20mn fix through the left wheel well.
You washer fluid chemistry may not be compatible with the washer system. That how you get reminded to only use MB supplies!
I was afraid to read it was your clear brakes leaking 😳

I am afraid to use a standard washer fluid and cause a seal leak, destroy the sensor or tiny pump itself.
This basic system is designed to need repairs.
