Dealer can't seem to find the leak. They pressure tested system and said it was ok. The car does not overheat but the low fluid light comes on. There is fluid on the ground. They replaced a hose the first time in but said they could not find anything the second time. I would have assumed that they have tracked the hoses and tanks for leaks. Any ideas!

Also we are thinking of selling this car but are having trouble pricing out it's worth using Edmunds etc. Any ideas!
