Check out what type of hose you're using from the cap to the refill tank. I
had the one used for gasoline, and these rot, and leak in a way that is
difficult to detect. I you have them, check them to see if they are hard and
brittle. I had this problem with our Jetta, and discovered the cause by
accidentally squeezing a coolant hose, the small hose from the expansion
tank was "sweating" coolant, no drips. Replace those with regular rubber
hose.
