My MY2009 TD4 has developed a 'dirty water' leak from turbo area, not yet been under to check exactly where from, no noises or other obvious symptoms.
Dumping about a cupful on shutdown, no significant level drop in coolant reservoir level. Unable to find anything similar in this forum, could it be ambient temp related? this is my first summer with FL2 and temp has been +30C last couple of days.

Condensate from the aircon? That exits in that general area.

as he said,the hotter the weather the more condensation from aircon

confirmed as condensate by switching air con off for a trip and no puddle

many thanks
