JasonR24 Posted February 19, 2017 Share Posted February 19, 2017 I'm assuming that this is the wastegate chucking out air but just to be sure I made a few videos which I'll try and upload. It sounds like when the first turbo hits its max boost (0.7 to 0.8 bar), it makes a rapid air release noise kind of like a whistle. It makes the noise when you hit the first turbos pressure limit in a high gear up until the second turbo at 3500rpm when it switches over. Hopefully this is normal as everything drives fine.

JasonR24 Posted February 19, 2017 Author Share Posted February 19, 2017 Yea I always check that thread it's brilliant but I can't see anything about this noise. I assume everything is fine but I'd rather be safe than sorry. Link to comment Share on other sites More sharing options...
