I also have a small leak, that produces a smelly blue fluid. I believe it is from the main transmission and accumulates on the metal pan imiediatly behind the back seats. It is hard to clean up because it is hard to reach and there are quite a few moving parts and stiffeners in the way.
What I do know is when some accumulates and seeps into the cabin, it smells bad and is harder to clean up.
Definatly blue color, where does it come from?
