Discovered the cause of my high pressure air leak!

Bimmina the michelin Mom hose...

Little hose with a big bulge that enters the intercooler from the turbo side
has a crack at the bottom edge of the upper hose clamp. Completely invisible
until removed and only leaked when boost reached about 1.2 BAR!

Worth checking if you are getting a really loud hiss under boost and can't
seem to find the culprit.

Hose is part number 035 145 760 anyone have a spare lying around?

(hey Martin P. - it looks like those hoses do let go!)
