I have water coming out of a pipe under my 2010 Renault Grand Scenic. There is not a smell to it. The water is coming from the passenger side and it is dripping from a wee rubber pipe.
For the sake of having answers for questions, I agree with the comments, and believe this is just condensation coming from the air conditioner.
You know how water collects on the outside of a cold glass when its warm outside? The same thing happens on the cold coil inside your AC system. Some cars just have a hole in the firewall that the water drains out of, and others, like your car, have a little rubber drain tube.
Critical fluids in the car have a color and normally have some smell. A clear, odorless liquid can really only be water and is of no concern.
