Hi, I have clogged windscreen sprayers in my 2019 W205. It was cleared during service but it was clogged again after a few sprays.
would anyone have instructions to get access to the hose?

if you have access to a workshop or somewhere with a compressor airgun.... you can unplug the water hose connecting to the sprayer (underneath the bonnet), then use the airgun to spray into the hose.

likely could be small debris stuck at the tank/pump area. my mechanic advised me not to use too much wiper wash fluid but use just plain old water.

hope this helps.
