I have a water leak on my 2013 CC, first noticed the other day when I was vacuuming my truck, I felt under the driver floor mat and it was wet. I pulled up the carpet and all the padding had soaked up all the water. I began to trace my leak back to the back corner of my rear door. The seals are all good and the door drains are clear, draining just fine when I put the water hose to the door and window seals. I did notice that the vapor barrier behind my door panel was not stuck down, looks like it has been like that since new since the butyl seal was not deformed at all. I resealed that up and dried the truck out thinking that I was good, but I am still having a leak. Today, I pulled off the A pillar trim to see if there was a leak through there, but it is dry as a bone. I am not sure what else to check, possibly the roof gutters?
