Reed Valve and Water Intrusion

Reed Valve and Water Intrusion
Hi,
I just had my 2012 S550 in for service due to water leaking from under the dash on the passenger side onto the carpet.
Under warranty, my MB dealer replaced a reed valve, a water filled blower motor, water soaked cabin filter and dried everything out.
They stated that a clogged reed valve was the problem which allowed exterior rain water to get into the inside of the vehicle.
I have never had a vehicle that was susceptible to water intrusion into the vehicle cabin.
The recent repair work resulting from the clogged reed valve has me concerned. Based on what just happened, this is obviously a serious and costly issue, that could potentially result in electrical issues in the future.
I did a google search that revealed a class action lawsuit regarding MB and this exact issue on cars up to 2006.
It seems the issue hasn’t been resolved on the W221’s.
I asked the dealer to send me a copy of any technical material from service bulletins, shop manual or whatever MB has, so that I can monitor this and I can clean this area if necessary, so this never happens again. They said they would get back to me.
So my question is, are there other S550 owners that have experienced this?
What do you do to monitor this so it isn't a problem in the future?
Even with a clean reed valve, are these cars susceptible to water intrusion in heavy, constant downpours.
I'm concerned.
Other than that, we love the vehicle.
I would appreciate all comments.
Thank you.
Please let me know.

What is the purpose of the reservoir, and when it overflows, how does the water enter the cabin interior.
In addition to the reed valve on the passenger side by the wiper, where else are they located.
To clean the valve, does the grille in the engine compartment snap on and off, or are there screws.
Thanks again.

I have an '06 C55 AMG in the shop because of intermittent starter problems. I used a trusted Benz repair shop who couldn't figure out the problem. They had to take it to the Mercedes dealership for them to figure it out. They did and said it was water intrusion, Repair cost estimate: $5,800. The shop I use, Hanz Wittler Automotive, told them no way and they would try to source the parts needed for the repair for me. What exactly are or where are "reed valves mentioned again on a C55 AMG?
