Whistling noise while on boost?

[paulabreu]

Hmm feels weird posting here lmao. Anyways, just got a 2010 ms3 last week, it has 80,000km and it's completely stock. It drove perfectly fine until Thursday when I noticed that the boost gauge is not hitting 15 psi and it drops even on WOT. I've checked and tighten all the hoses and everything seems fine.

I've been searching on msf and some threads says that the stock turbo inlet hose tends to come loose but mine is perfectly tight. Same as the hoses coming out of the stock bpv.

What else should I check before I take it in to jimmy

Thanks in advance

Forgot to mention, it also sounds like if I had an aftermarket SRI.

Sounds to me like your engine has a turbo.

Lol... Well It's way louder in person and it wasn't like this for the first few days, also it doesn't feel like it's holding boost?

He's coasting in neutral. You can tell from the speedometer


Check your recirc hose

Thanks so much, I'm inspecting the hoses right now and everything looks tight, engine light went off but it's still having the same symptoms, :/

[paulabreu]

Solved. Lol... The hose that comes out of the throttle body was completely loose.
