hi guys
my bp5 auto 2003 has lost ALL boost and has a strange sound coming from the area. the sound is kind of a knock ( sorry for the bad description ) only when boost should be starting to kick in. the person driving it at the time said it started off sounding like air hissing out ( like when you pull the valve out of a tire) i cant see any lines that come loose. but i have not been able to get the time to get in there and look properly. i did notice on a very quick inspection that there is oil around the waste gate, inter cooler area.
my oil levels look fine and cant find any obvious leaks in that area with a quick look.
any help or ideas, guys would be great
cheers
