    Loud Whistle coming from the engine of my C7 S7 - Crankcase Apparently

    Guest-only advertisement. Register or Log In now!
    So, I was driving yesterday and I heard a loud whistle coming from the engine at idle and up to about 1500 - 2000 RPMs. I could make it stop as long as I was accelerating. But it was god awful when sitting at lights or when parking. To the point where I was shutting her down at lights and hiding behind my dark tint.

    Here is a video link of the noise and my initial troubleshooting:

    Took her in and apparently this is common in other models but the stealership had not seen this from the S7 yet. Just my luck! I will report more as soon as I get the service order back tomorrow but the short answer is the baffle / seal on the crankcase is leaking.

    Hope this helps anyone else out there that experiences this.

    My first time posting and hope to contribute more!

    Had same issue with my '13 S6. It's a reasonably easy fix.

    Had it too - 200 miles after the apr tune. I was nervous. After market warranty never found the tune and covered the big $$ repair!
