How do I get access to my 2 Firewall water drain tubes,2000 Passat 2.8L 30 valve Wagon GLS

What is your question?

I was just advised yesterday for 1st time since buying this car new 18 yrs ago about these 2 Firewall drain tubes are likely the cause of floorboard under carpet full of water. I was trying to find them and cannot see a thing and realize I probably need to remove some things to gain access to these tubes and hoping I can get exact directions what has to be removed so I can clean out these 2 water drain tubes that have not been touched in 18 yrs of driving. I was assured 3-4 months ago my sunroof drain tubes are cleaned out perfect however I have not known a thing about the 2 Firewall drain tubes I was advised are on each side of the Firewall . Thank YOU VERY much for your help in this matter WILLIAMHWEBB.com

How long has your 2000 Volkswagen Passat had this problem?

I was just advised for 1st time yesterday about these 2 drain tubes since I bought the car new 18 yrs ago and am pretty certain they are the cause of water in drivers side floor
