Air (boost?) escaping underload left hand side engine.

[Dagilmo]

Hi All,

Underload there is a very clear and distinct sound of air escaping under pressure from the left side of the engine bay. I've previously replaced the top intercooler hose and it seems OK (sound not coming from there anyway) and am thinking it could be a one of the other hoses, the shorter ones that came with the hose kit. On the weekend, I'm going to pull a few things off and see what I can see.

Thoughts?

I find it hard to believe you have a leak that you can hear and you’re not getting a P006A message (MAF versus MAP discrepancy).

Thanks. No codes. Car running fine and driving OK but maybe a little under power through the mid range (also could be in my head.)
