Hi folks, my first post, I need a bit of advice. My son in law's 2006 A4 diesel (40k on clock) has had the small (about as thick as your thumb) steel pipe come out of the side of the turbo, making a terrible din! RAC pop'ed it back in with a crow bar and it's off to the dealer, probably for replacement under warranty, tomorrow. Has anyone had this happen ? looks like it is clamped in position by a two bolt flange. Only serviced by dealer so hope no 'excuses' by them! mickyal.
