Anyone else have any new info on this coolant return line from the turbo as there is not a whole lot info on the replacement of this part? I have noticed that mine leaks only on certain days, sometimes only a little and sometimes it drains the whole coolant reservoir tank. Makes no since on why it would only leak sporadically and would like to replace to ease my mind, but seems likes dealers are quoting very different prices to replace this part from some of the posts I have read.
