Thanks for the responses so far.
Ok, the dealer said "electrical secondary water pump that is dripping coolant". It's near the bottom of the radiator slightly to the passenger side. I asked if it might be just a bad hose or connection. The advisor said no and recommended "to replace the pump and we will re-check the system".
I want to get a second opinion. Anyone can recommend a honest reliable VW mechanic in the Silicon Valley/San Jose area?
Thanks again!
