It could possibly be a blocked ccv, I've heard of them making noises before-look on utube

Just done the test found on YouTube of taking the filler cap off whilst the engine is running to see if there's much suction, there is suction but I wouldn't say it's strong suction, is a bit of suction normal?

Hi, it's a bit of a vague area but there is supposed to be negative pressure but not to much!

Check lower intake boot for holes around joint between large throttle body hose and smaller ICV hose

Fuel pump whine? I'm sure mine has a tiny one, that I could hear with the roof down, might be normal. However, my exhaust mod means I no longer hear it
