Hello, I write because I bought a car vw passat b5 version after lifts only there is a problem with it was not raining it was all ok and now it's autumn is back from the passenger side is wet on the floor I really do not know why I checked under the battery if it is clogged and put in wire half a meter into this hole and it seems to me that there is nothing jammed here is everything ok. So I lifted the chair in the back and pulled out the lining in the back and it is really wet but you can not see anything coming out. And the black film in a way how to deal with it and do so I count on the help of professionals.
