ML 350 sunroof drain clogged and caused a crazy leak inside the car. After the fox I've been lucky and have had no leaks but some one posted in the comments below that they had a leak and suggested to secure the new hose with silicone around it so the water doesn't seep in the cabin from above. I will definitely try to do so myself as it does seems like a smarter way to fix. once done I will update the video accordingly. Incase someone is looking for the size of the hose, it's 13mm. Thanks for watching!
