Can anyone tell me, when running the output diagnostics...
... on the by-pass valve control module (N249) if I should hear a hissing noise coming from the rear of the engine. I know the fuel pump runs and I think the sound I hear is the FPR. But I'm not sure. I would just like to know if the hissing is a vacuum leak.
