This is a 2013 Mercedes
This is a 2013 Mercedes Benz S550 w221 model which belongs to my employer Dr Soap. If you experience wet floorboards inside your car, I show you what steps you need to take to prevent this from happening. There's an important water drain system Mercedes put on the S550 to keep the firewall dry as well as keeping water from entering the cars internal air conditioning system. You'll need to focus on 5 drains along the cowl section just below the windshield where the wipers are connected. Keeping these drains free from leaves and other debris will help them to do their job keeping your car from flooding and destroying expensive components which make the S550 the highest quality car on the road today.

I mentioned using a fish tape to push debris through the cowl drain. However, I've discovered the best way to clear them is to use an air compressor Kobalt blow gun that has a blue beveled tip on it and blow from the bottom of the drain upwards. Doing this will blow any debris that's in the drain tubes out at the top. I use a 200 PSI 4 Gallon Air Compressor with a Kobalt blow gun attached to the air hose. I found out this is the method used by dealerships when the car is still under warranty.
Before using a blow gun as described above, make sure you watch the below video which shows you how I modified the drain tubes in a way that accommodates the Kobalt blow gun.
This other video I made will show you how to modify your drains for better flow which can help prevent them from clogging. You'll definitely want to do this, It only requires about $10 at your local hardware store and is very effective for keeping water flowing through your cowl drains (don't skip this or put it off, its important if you park near trees) Mercedes should have did a recall and made this correction for owners but didn't, so you have to do it:
