Hi all,

searched but not really found any answers.

Below about 2200 rpm when coming on boost my car sounds like it has a leak. I can hear a hissing sound. Above 2200 rpm this disappears, the car seems to pick up a bit more, as if some thing has sealed. I've checked the boost pipes and so far can't find any leaks.

the car drives ok, returns good mpg but if there is an issue I'd like to sort it sooner rather than later.

Ive scanned with vcds and no fault codes.

cheers

matt
