I have a 2015.5 V60 CC. After having the seat covers replaced for flaking leather we are now having large amounts of a clear odorless gel/oil collecting on the rear passenger floorboard. It is at the dealer for the third time, with no idea or explaination for what it is simply a cleanup. It is coming from under the passenger seat and pooling in the back floor mat. It appears to be on the top of the floor heater vent from dripping, but they say it can't be coming from the seat. We do not have cooled seats. Has anyone ever heard of this problem or have any ideas to help.
