OK I have a coolant leak that will only drip when the car cools off....its coming from that center drop down drip pan that's on the bottom of the engine....I've had the system tested under pressure and they found the hose that goes to the alternator was leaking that was replaced....During the inspection no other areas / hoses where leaking....What I have found is that I can drive the car all day with not a single leak...then at night when I park in the garage I see a small green puddle in the AM about 3 inches wide and about 2 feet long or something like that....its quite annoying!! ....What ever it is will not show up under pressure its in the cool off area...what ever that means.
Any other 540i drivers had this little problem.....about the only thing that I can see to do is wait for it to start leaking more regularly and see if I can find it that way.....Also is there an overflow valve on these cars?
