Hey everyone. Ive been having a slight coolant leak on my 2006 2.0t fsi A3 58kmiles. The leak is coming from the hose that i believe comes off the charge pipe. Not from the charge pipe/hose connection but the other end of the hose to what I believe is connected to the radiator or intercooler?. It was very slightly loose at the connection and I pushed it back in and wiped it off. (Can get pictures if needed) That's the only area it leaks from. Obviously it will have some drips on the splash guard. I'm slightly confused. I've had to put in maybe 1/3 of a jug of coolant in the past 6months. What is this from and is it a really bad thing that can lead to something worse? Thanks.
